Q: When is the use of respirators required? A: OSHA’s respirator standard, 29 CFR 1910.134, requires the use of respirators to protect employees from breathing contaminated and/or oxygen-deficient air when effective engineering controls are not feasible, or while they are being instituted.
When would you need respiratory protection?
Millions of workers are required to wear respirators in various workplaces throughout the United States. Respirators protect workers against insufficient oxygen environments, harmful dusts, fogs, smokes, mists, gases, vapors, and sprays. These hazards may cause cancer, lung impairment, diseases, or death.
What is required before respiratory protection can be used?
Prior to issuing a respirator, employers must have a written respiratory protection plan. The plan is required to include key information such as respirator selection, medical clearance/questionnaire, training, fit testing, and proper use/storage of the respirator.
Which conditions may compromise your ability to use a respirator?
The following conditions may compromise the effective use of the respirator and jeopardize worker protection: facepiece seal leakage; removing the respirator at the wrong times in hazardous atmospheres; not properly performing user seal checks; or not properly repairing defective parts.
What standard requires respiratory protection training?

What are the three types of respirators?

What must be performed every time a respirator is put on?

How long can you wear a full face respirator?
