Respiratory Protection Program Guide: Hazard Assessment, Medical Evaluation & Training

Section 1: Introduction to Respiratory Protection Programs

Fit testing is an essential component of respiratory protection, but it’s only one element of a comprehensive program. Effective respiratory protection requires a systematic, documented approach addressing hazard identification, exposure assessment, equipment selection, medical evaluation, training, maintenance, and ongoing program evaluation. This comprehensive framework—known as a Respiratory Protection Program (RPP)—ensures workers receive genuine protection from airborne hazards, not merely the appearance of protection.

What is a respiratory protection program: An RPP is a structured,written program that establishes policies, procedures, and practices for selecting, using, and maintaining respiratory protection equipment. It assigns responsibilities, establishes training requirements, and creates systems for monitoring program effectiveness. A comprehensive RPP integrates all aspects of respiratory protection into a cohesive, managed system rather than treating respirators as standalone pieces of equipment.

Why comprehensive programs are needed: Respiratory hazards cause irreversible lung diseases—silicosis, asbestosis, coal workers’ pneumoconiosis, occupational asthma, chronic obstructive pulmonary disease, and infectious diseases like tuberculosis. These diseases develop gradually from cumulative exposures, often without immediate symptoms warning the worker. Once established, these diseases are incurable and progressive. The only effective strategy is prevention through systematic hazard control and respiratory protection when exposure cannot be eliminated.

Providing respirators without a comprehensive program creates a false sense of security. Workers may use the wrong respirator for the hazard, fail to achieve adequate fit, neglect maintenance, or use respirators unnecessarily when engineering controls would be more effective. Systematic programs prevent these failures.

AS/NZS 1715:2009 program requirements: The Australian/New Zealand Standard for Selection, Use and Maintenance of Respiratory Protective Equipment (AS/NZS 1715:2009) establishes minimum requirements for respiratory protection programs. Compliance with this standard is mandatory under Work Health and Safety regulations in all Australian jurisdictions. The standard requires:

Written respiratory protection program
Designated program administrator
Hazard assessment and exposure monitoring
Respirator selection based on hazards and required protection factors
Medical evaluation of respirator users
Fit testing for tight-fitting respirators
Training for all respirator users
Maintenance, cleaning, and storage procedures
Program evaluation and quality assurance

Benefits beyond compliance: Beyond regulatory compliance, comprehensive RPPs provide:

Reduced occupational illness: Preventing respiratory disease protects workers and reduces workers’ compensation costs
Improved productivity: Workers confident in their protection focus on work without distraction or concern
Regulatory protection: Documented programs demonstrate due diligence during inspections or after incidents
Legal defensibility: Comprehensive programs reduce liability exposure in litigation
Competitive advantage: Strong safety reputation attracts and retains quality workers

Industries with high respiratory hazards—construction, healthcare, mining—gain substantial value from well-implemented RPPs.

Section 2: Respiratory Hazard Assessment

Respiratory protection begins with understanding what hazards exist, where they occur, and at what concentrations workers are exposed.

Identifying Respiratory Hazards in the Workplace

Types of respiratory hazards: Workplace respiratory hazards fall into several categories:

Dusts: Solid particles generated by mechanical processes (crushing, grinding, cutting, drilling, blasting). Includes:

Silica dust (concrete, stone, rock, sand)
Coal dust (mining)
Wood dust (carpentry, manufacturing)
Metal dust (grinding, polishing, machining)
Grain dust (agriculture, food processing)
General nuisance dust

Fumes: Solid particles formed by condensation of vaporized metals. Common in:

Welding (metal fumes from welding rod and base metal)
Foundry operations (metal casting)
Smelting operations

Mists and sprays: Liquid droplets suspended in air:

Paint spray (spray painting, coating)
Pesticide application
Metalworking fluid mists (machining)
Disinfectant mists (cleaning)

Gases: Substances that are gaseous at normal temperature and pressure:

Carbon monoxide (combustion, diesel engines)
Hydrogen sulfide (sewers, petroleum, mining)
Nitrogen dioxide (welding, diesel exhaust, silos)
Chlorine (water treatment, chemical processing)

Vapors: Gaseous form of substances normally liquid or solid at room temperature:

Organic solvents (painting, degreasing, cleaning)
Gasoline/diesel vapors
Chemical processing vapors

Biological hazards: Living organisms or products of living organisms:

Bacteria (tuberculosis, legionella)
Viruses (influenza, COVID-19, measles)
Fungal spores (mold, histoplasmosis)
Endotoxins (organic dust)

Sources by industry: Hazards vary by industry:

Construction: Silica dust, asbestos (demolition/renovation), welding fumes, paint spray, diesel exhaust
Manufacturing: Metal dust/fumes, chemical vapors, paint spray, general dust
Healthcare: Airborne infectious diseases, disinfectant vapors, medication aerosols
Mining: Coal dust, silica dust, diesel particulate matter, explosive residues (nitrogen oxides), toxic gases
Agriculture: Grain dust, pesticide spray, ammonia (livestock facilities), biological agents

Work process analysis: Identify hazards by analyzing work processes:

Review all work tasks: List every task workers perform, particularly those involving cutting, grinding, heating, spraying, chemical handling, or confined spaces
Observe work activities: Walk through work areas observing actual practices (not just written procedures)
Consult with workers: Experienced workers often know hazards managers may overlook
Review safety data sheets (SDS): Every chemical used in the workplace should have an SDS identifying hazardous components and associated health risks
Chemical inventories: Comprehensive list of all chemicals, including trade names, manufacturers, quantities, and locations

Exposure Assessment Methods

Once hazards are identified, assess worker exposure levels to determine if they exceed acceptable limits.

Air monitoring and sampling: Direct measurement of airborne contaminant concentrations.

Personal air sampling: Worker wears a small air pump and sampling device throughout their shift. The pump draws air through a collection filter or absorbent tube at a controlled flow rate. Analysis determines time-weighted average concentration for the shift.

Advantages:

Measures actual exposure to individual worker
Accounts for work practices, movement patterns, and microenvironments
Most accurate representation of worker exposure

Disadvantages:

More expensive than area sampling
Requires worker cooperation (wearing equipment all shift)
Labor-intensive (requires technician to set up, collect, analyze)

Area air sampling: Stationary monitors placed in work areas measure ambient concentrations. Provides data on general air quality but doesn’t capture individual worker exposures.

Advantages:

Less expensive than personal sampling
Can monitor continuously over extended periods
Useful for identifying contamination sources

Disadvantages:

Doesn’t capture actual worker exposure (workers move through varying concentration zones)
May underestimate or overestimate personal exposures

Real-time monitoring: Direct-reading instruments provide instant concentration readings. Used for:

Identifying peak exposures or high-concentration events
Verifying ventilation effectiveness
Emergency response (detecting hazardous atmospheres)
Oxygen concentration monitoring

Common instruments:

Particulate monitors (dust monitors, photometers)
Gas detection meters (single-gas or multi-gas)
Oxygen meters

Gravimetric analysis: Collected samples are analyzed in laboratory. For dust, filters are weighed before and after sampling to determine mass of dust collected. For chemicals, samples are analyzed using gas chromatography, mass spectrometry, or other analytical methods.

Exposure measurement: Exposure results are expressed as:

Time-weighted average (TWA): Average concentration over a specific time period (typically 8 hours). Example: 0.15 mg/m³ respirable silica over 8 hours.

Short-term exposure limit (STEL): Maximum average concentration for short periods (typically 15 minutes). Protects against acute effects from brief high exposures.

Ceiling limits: Absolute maximum concentration that should never be exceeded, even instantaneously.

Comparing to workplace exposure standards (WELs): Measured concentrations are compared to exposure standards. In Australia, Safe Work Australia publishes Workplace Exposure Standards for Airborne Contaminants. If exposure exceeds the WES, controls (engineering, administrative, or PPE) are required to reduce exposure below the standard.

When to conduct air monitoring:

Initial assessment: When beginning work with airborne contaminants, baseline monitoring establishes exposure levels
After process changes: New equipment, materials, or processes may alter exposure levels
Periodic reassessment: Annual or biennial monitoring verifies controls remain effective
Following incidents: Spills, equipment failures, or worker symptoms suggesting overexposure
Regulatory requirements: Some industries (mining, particularly) have mandatory monitoring frequencies

Workplace Exposure Standards

Understanding Australian WES: Safe Work Australia Workplace Exposure Standards list time-weighted average (TWA) concentrations for hundreds of chemicals and dusts. These represent airborne concentrations to which most workers can be repeatedly exposed without adverse health effects.

Important principle: WES are not a sharp dividing line between “safe” and “unsafe.” They’re administrative thresholds based on current scientific knowledge. Some workers may experience effects below WES (individual susceptibility varies). WES should be viewed as maximum acceptable levels, with good practice targeting exposures as low as reasonably achievable (ALARA).

Safe Work Australia Hazardous Chemical Information System (HCIS): Online database providing WES for specific chemicals, health effects information, and risk management guidance. Free access at www.safeworkaustralia.gov.au.

Immediately Dangerous to Life or Health (IDLH) values: Concentrations representing immediate danger—either immediate death/permanent injury, or concentrations preventing escape from the environment. IDLH values (published by NIOSH in the US, adopted in Australia) trigger requirements for supplied-air respirators or SCBAs. Air-purifying respirators are inadequate in IDLH atmospheres.

Action levels and trigger points: Some regulations establish “action levels” at fractions of the WES (commonly 50% of WES). Exceeding action levels triggers specific requirements (medical surveillance, increased monitoring frequency, etc.) even if exposures remain below the WES.

Hazard Control Hierarchy

Before selecting respiratory protection, apply the hierarchy of controls to eliminate or minimize exposures.

Elimination: Completely remove the hazard. Most effective control but often impractical.

Example: Eliminate silica exposure by substituting non-silica-containing materials (replace sandstone paving with concrete pavers)

Substitution: Replace hazardous substances with less hazardous alternatives.

Examples:

Use water-based paints instead of solvent-based paints
Use wet methods (water suppression) for dust-generating activities instead of dry methods
Replace toxic chemicals with less toxic alternatives

Engineering controls: Isolate workers from hazards through physical means:

Ventilation: Local exhaust ventilation (LEV) captures contaminants at source before they enter breathing zone. General ventilation dilutes airborne contaminants.
Enclosure: Contain dusty or chemical processes in enclosed spaces
Isolation: Perform hazardous processes in separate areas away from other workers
Automation: Remote operation removes workers from exposure areas

Administrative controls: Reduce exposure duration through work practices:

Job rotation: Rotate workers through high-exposure tasks to limit individual exposure
Work scheduling: Perform high-exposure tasks during periods when fewer workers are present
Work practices: Standard operating procedures that minimize exposure (wet methods, enclosed handling)

PPE (respiratory protection): Last line of defense when higher-level controls cannot reduce exposure adequately. Respirators depend on worker use, fit, and maintenance—much less reliable than engineering controls. Regulations require exhausting higher-level controls before relying on respirators.

When respirators are appropriate: Respirators are the primary control only when:

Engineering and administrative controls are technically or economically infeasible
During installation or maintenance of engineering controls
During emergency response
During non-routine operations where engineering controls are impractical
As interim protection while permanent controls are being implemented

Determining Required Protection Factors

Once exposure levels are measured, calculate the required assigned protection factor (APF).

Calculating required APF:

Required APF = Measured Exposure Concentration ÷ Workplace Exposure Standard

Example 1: Silica dust

Measured exposure: 0.3 mg/m³ respirable crystalline silica
WES: 0.05 mg/m³
Required APF = 0.3 ÷ 0.05 = 6

Selecting appropriate respirator: Required APF of 6 means the respirator must reduce exposure to 1/6th of ambient concentration. Half-mask respirator (APF 10) exceeds the required APF of 6, so it’s adequate.

Example 2: Organic vapor

Measured exposure: 850 ppm toluene
WES: 50 ppm
Required APF = 850 ÷ 50 = 17

Required APF of 17 exceeds half-mask capability (APF 10). Full-face respirator (APF 100) or PAPR (APF 25-1,000) is required.

Assigned Protection Factors (APFs) for common respirators:

Respirator Type	APF
Half-mask (disposable or elastomeric)	10
Full-face respirator	100
PAPR – loose-fitting hood	25
PAPR – tight-fitting half-mask	50
PAPR – tight-fitting full-face	1,000
Supplied-air (demand mode)	10
Supplied-air (continuous flow)	1,000
SCBA (pressure-demand)	10,000

Safety factors: Apply safety margins—don’t select respirators where required APF equals rated APF. If required APF is 8, select APF 10 respirator (acceptable, but minimal margin). If required APF is 15, select APF 100 respirator (not APF 10), providing significant safety margin.

Documentation

Hazard assessment report: Document the hazard assessment process and findings:

Date of assessment
Areas and tasks assessed
Hazards identified (with CAS numbers for chemicals)
Exposure measurement results
Comparison to WES
Engineering and administrative controls in place or planned
Required protection factors
Selected respirator types
Signature of qualified person conducting assessment

Air monitoring results: Maintain records of all air monitoring:

Sampling date and duration
Worker name (personal samples) or location (area samples)
Sampling method and analytical method
Results (concentrations)
Comparison to WES
Actions taken if WES exceeded

Control measure evaluation: Document that hierarchy of controls was considered and higher-level controls were implemented where feasible before relying on respirators.

Section 3: Medical Evaluation for Respirator Use

Not all workers can safely use respiratory protection. Medical evaluation identifies contraindications and ensures workers are physically capable of respirator use.

Why Medical Evaluation is Required

Physical stress of respirator use: Respirators impose physiological burden:

Increased breathing resistance: Drawing air through filters requires effort, increasing work of breathing
Dead space: Air space inside facepiece contains exhaled CO₂ that’s rebreathed, slightly increasing CO₂ levels
Heat and humidity: Exhaled air trapped inside facepiece creates hot, humid microclimate
Weight: Respirators (particularly full-face and PAPRs) add weight to head and neck
Psychological stress: Some individuals experience claustrophobia or anxiety wearing respirators

Healthy workers tolerate these stresses easily. Workers with cardiovascular or respiratory disease may experience symptoms (chest pain, shortness of breath, dizziness) or exacerbation of underlying conditions.

Pre-existing medical conditions: Conditions that may contraindicate respirator use or require restrictions:

Cardiovascular disease: Coronary artery disease, heart failure, uncontrolled hypertension, arrhythmias
Respiratory disease: Asthma, COPD, emphysema, pulmonary fibrosis, lung cancer
Psychological conditions: Severe claustrophobia, panic disorder, severe anxiety
Neurological conditions: Seizure disorders (if seizure occurs while wearing respirator in hazardous atmosphere, outcome may be fatal)
Musculoskeletal conditions: Severe neck or back problems may be exacerbated by respirator weight (particularly PAPRs)

AS/NZS 1715:2009 requirements: The standard requires medical assessment before fit testing and initial respirator use, and periodic reassessment.

WHS duty of care: Employers have legal duty to ensure workers are medically fit for assigned work, including respirator use. Requiring respirator use without medical evaluation breaches this duty and creates liability exposure.

Medical Questionnaire

Medical evaluation begins with a questionnaire completed by the worker.

Sample medical evaluation questionnaire components:

Section 1: Personal Information

Name, date of birth, gender
Current job title and duties
Type of respirator to be used (half-mask, full-face, PAPR, SCBA)
Expected frequency and duration of respirator use

Section 2: Medical History

Questions address:

Current medications
History of lung disease (asthma, bronchitis, emphysema, tuberculosis)
History of heart disease (heart attack, heart failure, angina, arrhythmias)
History of high blood pressure
History of seizures
History of claustrophobia or anxiety disorders
History of back or neck problems
Current respiratory symptoms (cough, wheeze, shortness of breath, chest tightness)
Current chest pain or heart symptoms
Diabetes
Pregnancy (current or planned)
Previous problems wearing respirators

Section 3: Work-Related Symptoms

Difficulty breathing at work
Cough or wheeze at work
Chest pain or tightness at work
Symptoms that improve away from work

Key health considerations:

Cardiovascular conditions: Heart disease increases risk during physical exertion. The additional work of breathing through a respirator may trigger angina or arrhythmias in workers with coronary disease. Uncontrolled hypertension increases cardiovascular stress.

Respiratory conditions: Asthma, COPD, and other chronic lung diseases reduce baseline lung function. The additional breathing resistance from respirators may cause intolerable breathlessness. However, mild, well-controlled asthma usually doesn’t preclude respirator use.

Psychological conditions: Severe claustrophobia makes respirator use intolerable. Panic attacks while wearing a respirator in a hazardous environment could be life-threatening if the worker removes the respirator.

Medications that impair breathing: Beta-blockers (blood pressure medication) can exacerbate respiratory symptoms. Some psychiatric medications affect breathing patterns.

Confidentiality and privacy: Medical questionnaires and evaluations are confidential medical records:

Stored separately from personnel files
Accessible only to occupational health staff and treating physicians
Workers have right to access their own records
Employers receive only fitness-for-duty determination (“cleared for respirator use” or “restrictions apply”), not detailed medical information

Occupational health physician review: A physician trained in occupational medicine reviews questionnaire responses. For workers with concerning responses (history of heart or lung disease, current symptoms, medication concerns), the physician may:

Request additional information from the worker’s treating physician
Conduct physical examination
Order diagnostic testing (spirometry, chest X-ray, cardiac evaluation)
Provide fitness-for-duty determination with any necessary restrictions

Medical Examination Components

For workers with concerning questionnaire responses, medical examination provides further evaluation.

Physical examination:

Cardiovascular examination (heart sounds, blood pressure, pulse)
Respiratory examination (lung sounds, breathing pattern, chest expansion)
Musculoskeletal examination (range of motion, strength)
Neurological examination (if seizure history)

Pulmonary function testing (spirometry): Spirometry measures lung volumes and airflow rates:

FEV₁ (Forced Expiratory Volume in 1 second): Volume of air forcefully exhaled in first second
FVC (Forced Vital Capacity): Total volume of air forcefully exhaled
FEV₁/FVC ratio: Indicates obstructive (low ratio) vs restrictive (normal ratio, both values low) lung disease

Spirometry identifies lung disease that may make respirator use difficult or unsafe. Results are compared to predicted values based on age, height, sex, and ethnicity.

Cardiovascular assessment: For workers with cardiac history or risk factors:

Resting electrocardiogram (ECG)
Exercise stress test (if significant cardiac concerns)
Cardiology consultation if indicated

Fitness for work determination: Based on questionnaire, examination, and test results, the physician determines:

Approved for respirator use without restrictions
Approved with specific restrictions (type of respirator, duration of use, etc.)
Not approved for respirator use

Spirometry Testing for Respiratory Health Surveillance

Beyond medical clearance, spirometry serves as health surveillance detecting early lung disease from occupational exposures.

What is spirometry: Objective lung function measurement. Worker takes deep breath and exhales forcefully into spirometer, which measures volumes and flow rates. Quick (5-10 minutes), non-invasive, objective.

Baseline spirometry before respirator use: Baseline testing establishes the worker’s normal lung function. Future tests are compared to baseline to detect decline.

Periodic spirometry: Annual or biennial spirometry detects lung function decline. Significant decline may indicate:

Occupational exposure causing lung damage (inadequate respiratory protection or excessive exposure despite protection)
Development of other lung disease (smoking-related COPD, asthma)
Need for enhanced respiratory protection (upgrading from half-mask to full-face or PAPR)

Early detection of respiratory disease: Spirometry detects disease earlier than symptoms appear. Lung function can decline 20-30% before workers notice breathlessness. Early detection allows:

Removal from high-exposure roles before irreversible damage
Enhanced respiratory protection
Smoking cessation counseling (smoking and occupational exposures compound effects)
Medical treatment to slow progression

FEV₁, FVC measurements:

Normal values: Predicted based on age, height, sex, ethnicity. Generally, 80-120% of predicted is normal.
Obstructive pattern: FEV₁/FVC <70% indicates airflow obstruction (asthma, COPD, silicosis)
Restrictive pattern: FEV₁ and FVC both reduced but ratio normal indicates reduced lung volumes (pulmonary fibrosis, advanced silicosis)

Integration with fit testing program: Schedule spirometry and fit testing together for efficiency. If spirometry shows concerning findings (significant decline), enhanced respiratory protection may be needed before fit testing.

Referral pathways for abnormal results: Workers with abnormal spirometry results should be referred to:

Respiratory physician for further evaluation (chest CT, bronchoscopy if needed, diagnosis, treatment)
Workers’ compensation system if occupational disease is suspected
Enhanced exposure monitoring to verify protection adequacy
Potential retesting on higher-protection respirators (full-face, PAPR)

Medical Clearance Process

Approval to wear respirators: Physician provides written determination:

“Worker [Name] has been medically evaluated and is cleared to wear [respirator types] for [job duties].”

Restrictions or limitations: Some workers may be approved with restrictions:

“Cleared for half-mask respirators only (not full-face or SCBA due to claustrophobia)”
“Cleared for PAPR only (not negative-pressure respirators due to lung disease)”
“Cleared for respirator use up to 4 hours per shift (cardiovascular concerns)”
“Cleared for respirator use with restriction: No heavy exertion (cardiac concerns)”

Restrictions must be accommodated through job modifications, alternative respirators, or alternative work assignments.

Temporary vs permanent clearance:

Temporary: Valid for specified period (e.g., 1 year, 2 years). Requires periodic re-evaluation.
Permanent: Valid indefinitely unless health status changes or worker reports problems

Most programs use annual or biennial re-evaluation.

Reevaluation triggers: Reeval uation required when:

Scheduled periodic reevaluation date (annually or biennially)
Worker develops new respiratory or cardiac symptoms
Worker reports difficulty using respirator
Significant weight gain or loss (>10 kg)
Physician recommends more frequent monitoring

Special Populations

Pregnant workers: Pregnancy affects respiratory protection in several ways:

Increased metabolic demand and breathing rate (respirators may be more uncomfortable)
Potential facial changes from fluid retention (may require fit test retesting)
Balance changes increasing fall risk (particularly with PAPRs or SCBAs adding weight)
Heightened concern about fetal effects from respiratory exposures (even with respirator use)

Medical evaluation should address pregnancy specifically. Some physicians recommend enhanced protection (upgrading to higher APF respirators) or reassignment to lower-exposure roles during pregnancy out of abundance of caution for fetal protection.

Aging workforce: Older workers have higher rates of cardiovascular and respiratory disease. Medical evaluation is particularly important for workers over 50 using respirators, especially full-face, SCBA, or during physically demanding work.

Workers with disabilities: Respiratory protection should accommodate workers with disabilities where possible:

Physical disabilities not affecting respiratory or cardiovascular function generally don’t preclude respirator use
Hearing or vision impairment may be accommodated with appropriate communication systems or procedures
Cognitive disabilities requiring clear, simple instructions and enhanced training

Reasonable accommodations: Under anti-discrimination laws, employers must provide reasonable accommodations for workers with disabilities or medical conditions unless doing so creates undue hardship. For respiratory protection:

Providing PAPR for worker who cannot tolerate tight-fitting respirators due to anxiety
Modified work schedules allowing rest periods for workers with cardiac concerns
Role reassignment to lower-exposure tasks

Section 4: Respirator Selection and Maintenance

With hazards assessed and workers medically cleared, select appropriate respirators and establish maintenance procedures.

Program-level respirator selection: Systematic respirator selection based on:

Required APF (from hazard assessment)
Contaminant type (particulate, gas/vapor, both)
Work environment (heat, humidity, exertion, communication needs)
User acceptance and comfort
Cost (purchase and ongoing consumables)

Approved respirator list development: Maintain list of approved respirator makes/models:

Include multiple models (2-3 options per respirator type) to accommodate facial diversity
Specify approved cartridge/filter types for each hazard
Document why each model is approved (APF, filter type, face fit range)

Procurement and distribution:

Centralized procurement ensures only approved models are purchased
Adequate stock levels prevent workers using unapproved alternatives when shortages occur
Issue respirators to individual workers (not shared) with assigned responsibility for care

Cleaning and disinfection procedures: Elastomeric respirators require regular cleaning:

Disassemble respirator (remove cartridges/filters, head straps, valves)
Wash components in warm water (up to 49°C) with mild detergent
Rinse thoroughly with clean water
Air dry on clean surface (do not use heat)
Disinfect if shared between workers: Immerse in disinfectant solution (e.g., quaternary ammonium compounds, dilute bleach, commercial respirator disinfectants) per manufacturer instructions, then rinse and dry
Reassemble after complete drying
Inspect before storage

Storage requirements:

Store in clean, dry location away from contaminated work areas
Protect from sunlight (UV degrades elastomers), extreme temperatures, chemicals, physical damage
Store in breathable containers (mesh bags, paper bags, plastic containers with ventilation holes)—not sealed plastic bags that trap moisture
Store inverted or in a way that prevents facepiece deformation

Inspection schedules:

Before each use: Worker inspects for cracks, tears, valve damage, strap condition
After cleaning: Thorough inspection during reassembly
Periodic: Supervisor or safety staff periodically inspects workers’ respirators (monthly or quarterly) to verify proper care

Repair and replacement policies:

Minor repairs (replacing straps, valves, head harnesses) are acceptable using manufacturer-supplied parts
Facepiece damage (cracks, tears, permanent deformation) requires replacement—do not attempt repair
Replace respirators at end of service life per manufacturer guidance (2-5 years for elastomeric respirators depending on use and care)

Defective equipment removal: Establish procedure for removing damaged respirators from service:

Workers must report defects immediately
Defective respirators tagged “out of service” and removed from work area
Replacement provided same shift
Tracking system monitors defect patterns (if one respirator model has high failure rates, consider alternative)

Section 5: Training Requirements

Even the best-selected, properly fitted respirator provides inadequate protection if workers don’t understand when and how to use it correctly.

Initial Respirator Training

AS/NZS 1715:2009 training requirements: The standard requires training for all respirator users before initial use and annually thereafter, covering:

Respiratory hazards in the workplace and health effects
Engineering and administrative controls, and why respirators are necessary
Respirator types, capabilities, and limitations
How to inspect, don, use, and remove respirators
User seal checks
Maintenance, storage, and care
Medical signs and symptoms limiting effective use
Workplace-specific procedures

Who needs training: All workers who may use respirators, including:

Regular users (daily or frequent use)
Occasional users (may encounter respiratory hazards intermittently)
Emergency responders (may don respirators during incidents)

When training is required:

Before initial respirator use
Annually thereafter
When new respiratory hazards are introduced
When new respirator types are introduced
When observations or evaluations indicate worker lacks knowledge or skill

Training Program Components

Respiratory hazard awareness: Workers must understand the specific hazards they face:

Identity of contaminants (chemical names, not just trade names)
Health effects of exposure (both acute and chronic)
Routes of exposure (inhalation, skin absorption, ingestion)
How hazards are controlled (engineering controls, administrative controls, PPE)
Why respirators are necessary (engineering controls reduce but don’t eliminate exposure)

Personalizing training to specific workplace hazards improves engagement and retention. Generic training on “dust” is less effective than specific training on “respirable crystalline silica causing silicosis.”

Respirator capabilities and limitations: Workers need realistic understanding of what respirators can and cannot do:

What respirators can do:

Filter airborne particles (when proper particulate filters are used)
Absorb gases and vapors (when proper chemical cartridges are used)
Provide protection when properly selected, fitted, worn, and maintained

What respirators cannot do:

Provide protection in oxygen-deficient atmospheres (<19.5% O₂)—supplied-air required
Provide protection in IDLH atmospheres (requires SCBA or SAR)
Protect against skin absorption of chemicals (requires additional PPE)
Compensate for inadequate engineering controls (not a substitute for proper ventilation)
Protect if not worn correctly (gaps, improper donning, facial hair, etc.)

Proper donning and doffing: Step-by-step demonstration and hands-on practice:

Inspect respirator before donning
Correct strap placement and tightening
Noseclip adjustment
Positive and negative pressure seal checks
Proper doffing without contaminating face or clothing (for contaminated environments)
Storage after removal

User seal checks: Detailed training on positive and negative pressure seal checks:

When to perform (every time respirator is donned)
Step-by-step procedures for each check
What passing checks feel like vs. failing checks
Troubleshooting failed seal checks (adjusting straps, noseclip, repositioning)
Demonstration, then worker practice under supervision

Maintenance and storage: Proper care extends respirator life and ensures continued protection:

Cleaning procedures (daily for elastomeric, after each use if heavily soiled)
Disinfection (when and how)
Inspection (what to look for, when to replace)
Filter/cartridge replacement (when and how to determine end of service life)
Storage (where and how to prevent damage and contamination)

Medical signs and symptoms: Workers must recognize symptoms indicating respiratory stress or exposure:

Difficulty breathing
Dizziness or lightheadedness
Nausea
Weakness or fatigue
Increased heart rate
Chest pain or tightness
Headache

What to do: If symptoms occur while wearing respirator:

Leave the contaminated area immediately
Remove respirator only after reaching clean area
Report symptoms to supervisor
Seek medical evaluation
Do not resume respirator use until medically cleared and problem is identified/corrected

Fit testing explanation: Workers should understand the purpose and process of fit testing:

Why fit testing is required (verify proper seal before use)
What to expect during testing (qualitative or quantitative, exercises, duration)
That fit testing is required annually and after changes
Responsibilities (arrive clean-shaven, bring typical eyewear, follow tester instructions)

Training Methods

Classroom instruction: Traditional lecture/presentation covering theory:

PowerPoint presentations, videos, handouts
Hazard information, regulatory requirements, program policies
Suitable for knowledge-based content

Hands-on practice: Practical demonstration and supervised practice:

Donning and doffing respirators
User seal checks
Cleaning and maintenance
Most effective for skill development

Competency assessment: Verification that workers have learned material:

Written test: Multiple-choice or short-answer questions testing knowledge (hazards, procedures, limitations)
Practical test: Observed demonstration of respirator donning, seal checks, and removal
Pass/fail criteria: Workers must demonstrate competency before being cleared for respirator use
Remediation: Workers who fail receive additional training and retesting

Competency-based assessment ensures training effectiveness. Simply attending training doesn’t guarantee learning—demonstration of competency does.

Refresher Training

Annual retraining: AS/NZS 1715:2009 requires annual training. Refresher training:

Reviews key concepts from initial training
Updates on any program changes (new hazards, new respirators, policy updates)
Addresses common problems identified through program evaluation
Reinforces proper techniques (seal checks, donning, maintenance)
Shorter than initial training (2-3 hours vs. 4-6 hours)

Trigger events for additional training:

Introduction of new respiratory hazards
Changes to respiratory protection program
New respirator models
Following incident or near-miss involving respiratory protection
When observations indicate workers are not using respirators correctly

Updated hazard information: As new information becomes available about hazards (revised exposure standards, new health studies), training should be updated and communicated to workers.

Training Documentation

Attendance records: Maintain training roster:

Training date
Topic covered
Trainer name and qualifications
Attendee names and signatures
Duration

Competency certificates: Issue certificate of competency to workers who successfully complete training and pass assessments. Workers carry certificates (or electronic equivalent) as proof of training.

Training materials retention: Maintain copies of all training materials, presentations, handouts, and tests. Demonstrates program content if questioned during incident investigation or regulatory inspection.

Section 6: Program Administration and Oversight

Effective programs require designated leadership, documentation, and ongoing evaluation.

Appointing program administrator: Designate a qualified individual as respiratory protection program administrator. Responsibilities include:

Overall program oversight and coordination
Conducting or arranging hazard assessments
Selecting respirators and maintaining approved respirator lists
Ensuring medical evaluations and fit testing occur
Developing and delivering training

Liaising with regulators and auditors

Qualifications: Administrator should have:

Training in occupational health and safety
Understanding of AS/NZS 1715:2009 and respiratory protection principles
Authority to implement program requirements and enforce compliance

Large organizations may dedicate full-time staff; smaller organizations may assign this responsibility to a safety manager or coordinator.

Roles and responsibilities: Clearly define responsibilities:

Program Administrator: Overall program management
Supervisors: Ensure workers are trained, fitted, and use respirators correctly; enforce compliance
Workers: Attend training, undergo fit testing, use respirators as required, maintain equipment, report problems
Occupational Health: Conduct medical evaluations and health surveillance
Procurement: Purchase only approved respirators and consumables
Senior Management: Provide resources, support compliance, lead by example

Program administrator and responsibilities
Hazard assessment procedures and results
Respirator selection criteria and approved respirators
Medical evaluation procedures
Fit testing procedures and frequency
Training requirements and content
Maintenance, cleaning, and storage procedures
Program evaluation methods

Template: Written program templates are available from Safe Work Australia, industry associations, and respiratory protection equipment manufacturers. Customize templates to reflect your specific workplace, hazards, and procedures.

Program evaluation and auditing: Systematic program evaluation ensures effectiveness:

Annual program review: Review all program elements, update based on changes
Workplace inspections: Regular workplace walks observe respirator use, identify problems
Respirator inspections: Periodic inspection of workers’ respirators assesses condition and care
User surveys: Anonymous worker feedback on respirator comfort, training quality, program effectiveness
Incident review: Investigation of any incidents involving respiratory protection failure
Compliance audits: Verify training currency, fit testing currency, medical clearances, approved respirator use

Continuous improvement: Use evaluation findings to improve:

Update training content based on knowledge gaps identified
Add respirator models to approved list if fit testing success rates are low
Enhance engineering controls to reduce reliance on respirators
Improve communication and engagement

Management review: Present program performance to senior management annually:

Compliance rates (training, fit testing, medical clearances)
Program costs
Incidents or near-misses
Program improvements implemented
Resource needs for coming year

Worker consultation: Engage workers and health and safety representatives in program development and review:

Seek input on respirator selection (comfort, usability)
Discuss barriers to compliance and identify solutions
Communicate program changes and rationale
Build ownership and buy-in

Section 7: Integration with Other Safety Programs

Respiratory protection doesn’t exist in isolation—integrate with broader safety management.

Confined space entry: Confined space entry procedures must address respiratory hazards:

Pre-entry atmospheric testing (oxygen, flammable gases, toxic gases)
Continuous monitoring during entry
Respirator requirements based on testing results
Emergency rescue respirators (SCBA) staged for rescuers

Emergency response: Emergency responders require specialized respiratory protection:

SCBA or supplied-air for IDLH atmospheres, fires, unknown atmospheres
Chemical-specific respirators for hazardous material spills
Enhanced training on emergency respirator use
Regular respirator maintenance and inspection (readiness critical)

Hazard communication: Respiratory protection program integrates with hazard communication (GHS, SDS):

SDS specify recommended respiratory protection
Workplace labels indicate when respiratory protection is required
Training addresses specific chemicals used in workplace

PPE program: Coordinate respiratory protection with other PPE:

Eye protection compatibility with respirators
Hearing protection compatibility (communication systems, earplugs vs. earmuffs)
Head protection (hard hats) compatibility with respirators
Ensemble considerations (combinations of multiple PPE)

Health surveillance: Integrate respiratory health surveillance with broader health monitoring:

Coordinate spirometry with fit testing appointments
Share findings (with appropriate consent) between occupational health and safety personnel
Refer workers with concerning findings for enhanced medical evaluation
Track trends (increasing rates of respiratory symptoms may indicate inadequate controls)

Section 8: FAQ Section

Q1: Do we need a written respiratory protection program?

Yes, AS/NZS 1715:2009 requires a written program for all workplaces where respirators are used. Even small businesses with minimal respirator use need documented procedures, though the program may be brief and simple.

Q2: Who can be a respiratory protection program administrator?

Any qualified person with training in occupational health and safety, understanding of AS/NZS 1715, and authority to implement requirements. For small organizations, a safety manager or coordinator typically fills this role. Large organizations may dedicate full-time staff.

Q3: How often should we conduct air monitoring?

Initially (when beginning work with airborne contaminants), after process or control changes, annually or biennially for ongoing operations, and following incidents suggesting overexposure. Specific industries like mining may have more frequent mandatory monitoring.

Q4: What if a worker is medically cleared but still can’t tolerate wearing a respirator?

Medical clearance confirms the worker CAN safely wear a respirator from a health perspective. If the worker psychologically cannot tolerate it (anxiety, claustrophobia) despite medical clearance, options include: additional desensitization training, switching to loose-fitting PAPR (less claustrophobic), role reassignment to non-respiratory-hazard work.

Q5: Can we use respirators instead of installing ventilation?

No. The hierarchy of controls requires elimination, substitution, and engineering controls before relying on PPE. Respirators are acceptable only when engineering controls are technically or economically infeasible, or as interim protection while engineering controls are being installed. Regulations do not permit using respirators simply because they’re cheaper than ventilation.

Q6: How do we train a linguistically diverse workforce?

Provide training in workers’ native languages using qualified interpreters or multilingual trainers. Provide written materials in multiple languages. Use visual aids, demonstrations, and hands-on practice (less language-dependent). Verify comprehension through practical competency assessment, not just written tests.

Q7: Who pays for medical evaluations—employer or worker?

Employer. Medical evaluations are a workplace requirement, not a personal medical expense. Employers must provide evaluations at no cost to workers, during work hours (or compensate if conducted outside work hours).

Q8: Can workers bring their own respirators from home?

Only if those respirators are on the approved respirator list and the worker has been fit tested on that specific make/model/size. Workers cannot use unapproved respirators. Best practice: Employer provides all respirators to ensure quality, appropriateness, and fit testing alignment.

Q9: How do we handle contractors who arrive with their own respirators?

Verify: (1) respirator is appropriate for the hazards in your workplace, (2) contractor has current fit testing on that specific respirator, (3) contractor has been medically cleared, (4) contractor has been trained. If any element is missing, contractor must use your organization’s equipment and undergo your program requirements, or be excluded from respiratory hazard areas.

Q10: What if we discover our respirators are inadequate for the hazards?

Immediately stop work in affected areas until appropriate respirators are procured and workers are fit tested. This may cause operational disruption, but continuing work with inadequate protection is unsafe and illegal. Expedite procurement and fit testing. Investigate how the error occurred and implement corrective actions to prevent recurrence.

Q11: How long should we retain respiratory protection program records?

Fit testing records: Duration of employment + 30 years
Medical evaluation records: 30 years after employment cessation
Training records: 3-5 years (or as specified by jurisdiction)
Air monitoring records: 30 years
Hazard assessments and program documents: Duration of program + 5 years minimum

Q12: Do office workers who occasionally visit production areas need fit testing?

If they enter areas requiring respiratory protection and may be exposed, yes. Alternatively, implement administrative controls preventing office workers from entering those areas, or timing visits when production is shut down and no exposure occurs.

Q13: Can we allow voluntary respirator use (workers choose to wear respirators even when not required)?

Yes, but you still have obligations: Provide training on limitations and proper use, ensure voluntary use doesn’t create hazards (e.g., tripping), verify respirators don’t interfere with required PPE. Fit testing is not required for voluntary use of disposable filtering facepieces (P2/N95) but is required for voluntary use of elastomeric respirators.

Q14: What if workers complain that respirators are too uncomfortable?

Investigate causes: Wrong size or model (try alternatives), improper adjustment (additional training), defective equipment (replace), unrealistic expectations (explain necessity, gradual acclimatization). Comfort is important for compliance, but protection is non-negotiable. Balance comfort and protection by offering multiple approved respirator options and ensuring workers are fitted to the most comfortable model that meets protection requirements.

Q15: How do we evaluate if our respiratory protection program is effective?

Track metrics: (1) Compliance rates (% workers with current training, fit testing, medical clearances), (2) Exposure monitoring trends (are exposures decreasing?), (3) Health surveillance trends (any respiratory illnesses?), (4) Incident rates (exposure incidents, respirator failures), (5) Worker feedback (satisfaction, perceived effectiveness). Effective programs show high compliance, stable or declining exposures, absence of respiratory illness, and positive worker feedback.
