Overview
This web page serves as a trusted supply for respiratory safety info. Thousands and thousands of staff throughout the USA depend on respiratory safety to maintain them protected on the job.

When an employer determines that staff want respiratory safety, the Occupational Security and Well being Administration (OSHA) requires the usage of NIOSH Accredited® respirators. The NIOSH Respirator Approval Program is liable for evaluating and approving respirators utilized in U.S. office settings.
Varieties
There are two principal forms of respiratory safety. Every respirator sort supplies a distinct stage of safety primarily based on its design:
- Air-purifying respirators (APRs)
- Ambiance-supplying respirators (ASRs)
Moreover, NIOSH approves 5 various kinds of APRs and ASRs for cover towards chemical, biological, radiological, and nuclear agents.
Every sort of respirator has an assigned safety issue. This means the extent of safety you may count on to obtain from that respirator. Table 1 of the OSHA Respiratory Protection standard presents the assigned safety issue for every respirator sort.

Ambiance-supplying respirators (ASRs)
ASRs present clear respiration air from a separate supply. These respirators defend you from many forms of airborne contaminants (particles, gases, and vapors) and, in sure instances, oxygen-deficient atmospheres. The various kinds of ASRs are:
- Provided-air respirators
- Self-contained respiration equipment
- Open-circuit (generally utilized by firefighters)
- Closed-circuit (used for entry or escape in industries resembling mining the place it is called a self-contained self-rescuer)
- Mixture supplied-air/self-contained respiration equipment
Respiratory safety packages (RPPs)
Workplaces lined underneath OSHA should set up a whole RPP when respiratory safety is required.
Highlight
