Respirator How-To Guide & Safety Checks

Essential procedures for proper respirator use and maintenance

Proper Respirator Fit and Use

Inspect Before Each Use

Before donning your respirator, perform a thorough visual inspection. Check the facepiece for cracks, tears, or distortion. Examine straps for elasticity and secure attachment points. Inspect cartridges and filters for damage, proper seating, and expiration dates. Ensure all valves move freely and seal properly. Any damaged components must be replaced before use.

Proper Donning Procedure

Hold the respirator by the straps or body, not the cartridges. Position the facepiece on your face, ensuring your chin is properly seated in the chin cup. Pull straps over your head - bottom straps should sit on your neck below your ears, top straps on the crown of your head. Adjust straps evenly for a snug but comfortable fit. The respirator should not shift when you move your head.

Perform User Seal Check

Positive Pressure Check: Cover the exhalation valve with your palm and breathe out gently. The facepiece should bulge slightly and no air should leak from the seal. Negative Pressure Check: Cover the cartridge inlets and breathe in gently. The facepiece should collapse slightly against your face and hold the vacuum. If you detect any leakage, readjust the straps and repeat the seal check.

Work With Proper Technique

Avoid touching the facepiece during use as this can break the seal. Do not remove your respirator in contaminated areas. Be aware of your filter/cartridge service life - replace based on manufacturer guidelines, breakthrough (detecting odor), breathing resistance, or time limits. Never prop your respirator on your forehead or around your neck as this damages the seal and may expose you to contaminants.

Proper Removal and Storage

Move to a clean area before removing your respirator. Lift bottom straps over your head first, then top straps, while holding the facepiece away from your face. Immediately place used respirator in a clean, dry storage area or bag. Never leave respirators in contaminated areas or where they can be crushed or damaged. Store away from direct sunlight and extreme temperatures.

Cleaning and Maintenance

Clean reusable respirators after each use. Disassemble removable parts carefully. Wash the facepiece and components in warm water with mild detergent. Use a soft brush for stubborn residue. Rinse thoroughly with clean water. Sanitize with manufacturer-approved disinfectant if sharing equipment. Allow all parts to air dry completely before reassembly. Inspect all components during cleaning and replace any damaged parts.

⚠️ Daily Safety Checklist

  • Inspect facepiece for cracks, tears, or distortion
  • Check all straps for proper elasticity and attachment
  • Verify cartridges/filters are correct type for hazards
  • Confirm cartridges are not expired or at end of service life
  • Test inhalation and exhalation valves function properly
  • Perform positive and negative pressure seal checks
  • Ensure cartridge gaskets are in place and sealing
  • Check for proper fit - no gaps between face and facepiece

When to Replace Filters and Cartridges

Particulate Filters (P100, N95, etc.)

  • Increased Breathing Resistance: When inhaling becomes noticeably more difficult
  • Physical Damage: Any tears, punctures, or deformation
  • Manufacturer Time Limits: Follow specific product guidelines
  • Contamination: Visible accumulation of particulates
  • Hygiene: End of shift in highly contaminated environments

Gas/Vapor Cartridges

  • Odor Breakthrough: Detecting chemical smell inside mask
  • Taste Detection: Any taste of contaminants
  • Irritation: Eye, nose, or throat irritation developing
  • Time-Based: Following manufacturer's change-out schedule
  • Cartridge Weight: Significant weight gain from absorption (if detectable)
  • End Serice Life Indicator: If equipped with ESLI feature

Important: Never Rely on Warning Properties Alone

Many hazardous substances have poor warning properties - you may not smell or taste them before dangerous exposure occurs. Always establish a cartridge change-out schedule based on:

  • Contaminant type and concentration
  • Work rate and duration
  • Environmental conditions (temperature, humidity)
  • Manufacturer recommendations
  • Change-out schedule calculators or monitoring

Annual Fit Testing Requirements

OSHA regulations (29 CFR 1910.134) require annual quantitative or qualitative fit testing for all tight-fitting respirator users. Fit testing must be performed:

  • Before initial use of a respirator
  • Annually thereafter
  • Whenever a different make, model, or size is used
  • When physical changes occur that could affect fit (weight change, dental work, facial scarring)

Fit Test Methods

Qualitative Fit Test (QLFT): Pass/fail test using irritant smoke, saccharin, or Bitrex. Person wears respirator and performs exercises while exposed to test agent. Detection of taste or smell indicates failed fit test.

Quantitative Fit Test (QNFT): Uses specialized equipment to numerically measure face seal leakage. Provides fit factor score - minimum acceptable is 100 for half-face respirators, 500 for full-face respirators. More objective than qualitative testing.

Factors That Affect Respirator Fit

  • Facial hair - even stubble can prevent proper seal
  • Eyeglasses - temple bars break the face seal
  • Jewelry - facial piercings interfere with sealing surface
  • Head coverings - hoods or scarves under straps
  • Physical changes - weight gain/loss, dental work
  • Scarring or deformities in the sealing area

Critical: Facial hair in the sealing area is absolutely prohibited. Even one day of beard growth can reduce protection by 90% or more.

Medical Evaluation Requirements

Before using a respirator in the workplace, OSHA requires a medical evaluation to ensure the worker can safely wear respiratory protection. This evaluation considers:

Medical Conditions Evaluated

  • Respiratory conditions (asthma, COPD, emphysema)
  • Cardiovascular disease or high blood pressure
  • Claustrophobia or anxiety disorders
  • Previous lung surgery or scarring
  • Current medications affecting breathing
  • Physical ability to wear equipment weight

The Evaluation Process

  • Complete OSHA medical questionnaire (Appendix C)
  • Reviewed by physician or licensed healthcare provider
  • Additional exams if questionnaire indicates concerns
  • Written determination of ability to wear respirator
  • Re-evaluation if health status changes
  • Confidential - employer receives clearance only

Common Respirator Problems and Solutions

Problem Possible Causes Solutions
Respirator leaking Improper fit, facial hair, worn straps, damaged facepiece Adjust straps, shave facial hair, replace worn components, try different size
Lens fogging Temperature difference, blocked exhalation valve, nose cup misalignment Clean lens, check valve operation, adjust nose cup, use anti-fog treatment
Difficult breathing Clogged filters, wrong filter type, blocked airways Replace filters/cartridges, verify correct filter selection, inspect air passages
Odor inside mask Expired cartridge, wrong cartridge type, poor seal, cartridge not installed Replace cartridges immediately, verify correct type, check seal, exit contaminated area
Skin irritation Dirty facepiece, too-tight straps, material sensitivity Clean respirator thoroughly, adjust strap tension, consider hypoallergenic barrier cream
Headaches Straps too tight, CO2 buildup, dehydration Adjust strap tension, check valve function, take breaks, stay hydrated

⚠️ When NOT to Use a Respirator

  • Oxygen levels below 19.5% - use supplied air instead
  • IDLH (Immediately Dangerous to Life or Health) atmospheres without proper SCBA
  • Unknown contaminants or concentrations
  • Failed seal check or damaged equipment
  • Expired or contaminated filters/cartridges
  • Wrong filter type for the hazard present
  • Medical clearance has not been obtained
  • Fit testing has not been completed
