Respiratory Protection HS 432
OSHA (29 CFR 1910.132) "Protective equipment … shall be provided, used, and maintained in a sanitary and reliable condition whenever it is necessary by reason of hazards of processes or environment, chemical hazards, radiological hazards, or mechanical irritants encountered in a manner capable of causing injury or impairment in the function of any part of the body through absorption, inhalation, or physical contact."
Hierarchy of Control • Engineering • Administration • Personal protective equipment (PPE)
PPE • Personal protective equipment • You must be trained in use and demonstrate understanding • Respirators • Gloves • Eye and face protection • Chemical-resistant clothing
The Occupational Safety & Health Administration (OSHA) requires employers to provide employees with PPE when there's a risk of exposure to various hazards OSHA does more than require employers to provide PPE. The agency also requires employees to USE the PPE that's provided.
Some people seem to think PPE is optional—or just too much trouble OSHA requires it, and so does ABC Corporation Since it exists to protect you, you shouldn't consider PPE any more trouble than putting on gloves on a day when the temperature falls below freezing or wearing sunglasses when the summer sun is shining in your eyes.

Disposable Respirators • Simple Filtering Devices • Snug Fit Is Required
Powered Air Purifying Respirators • Same Limitations As Other Air Purifying Respirators • Provide A Higher Protection Factor Due To Positive Pressure In The Facepiece
Supplied Air Respirators • Types • Airline • Self Contained Breathing Apparatus {SCBA }
Supplied Air Respirators • Cannot provide protection against every type of hazard • Inspect before every use • Clean after every use • Store properly
Fit Testing • QUALITATIVE • Negative pressure check • Positive pressure check • Banana oil/irritant smoke test
Rainbow Passage • When the sunlight strikes raindrops in the air, they act like a prism and form a rainbow. The rainbow is a division of white light into many beautiful colors. These take the shape of a long, round arc, with its path high above and its two ends beyond the horizon. There is, according to legend, a boiling pot of gold at one end. People look, but no one ever finds it. When a man looks for something beyond reach, his friends say he is looking for the pot of gold at the end of the rainbow.
Fit Testing • QUANTITATIVE • Concentration of a test aerosol is measured inside and outside the respirator. • Coutside/Cinside is compared to theoretical protection factor of respirator to check if it fits the wearer adequately.
