A Bad Atmosphere
• Can be deadly
• Requires a respirator.

Types of Hazardous Atmospheres• Deficient
• Contaminated
• Hazard determines respirator used.

Air-Purifying Respirators
• Enough oxygen in the air
• Three types:
– Particulate removing
– Vapor and gas removing
– Combination.

Supplied Air Respirators
• For oxygen-deficient atmosphere
• Two types:
– SCBA (and SCUBA)
– Air supplied from outside source.

Respiratory Protection Plan• Establishes proper procedures
for:
– Respirator selection
– Respirator use
– Respirator maintenance.
• Evaluates respiratory hazards.

Medical Evaluation
• Medical screening usually required
• Ensures you are physically able to use equipment
• Questionnaire
• Physical examination.

Fit Testing
• Tight face-to-mask seal
• Qualitative / Quantitative
• Negative / Positive pressure test.

Respirator Maintenance: InspectionCheck for:
• Holes or rips
• Broken or loose connectors and fittings
• Detergent residue or dirt
• General cleanliness.

Respirator Maintenance: CleaningSteps include:
• Disassemble mask
• Wash components
• Disinfect if needed
• Rinse and drain
• Hand dry.

Respirator Maintenance: Storage• Place in plastic bag.• Store with valves and tubes undistorted.• Protect from:
• Dust• Sunlight• Heat• Cold• Moisture• Chemicals.
Respirator maintenance is YOURresponsibility!
