What is one of the key regulatory frameworks governing the use of respirators?

The Occupational Safety and Health Administration (OSHA) is the correct answer because it plays a crucial role in regulating workplace safety and health standards, including the use of respirators. Under OSHA regulations, employers are required to provide appropriate respiratory protection to workers who are exposed to airborne contaminants. This includes ensuring that respirators are properly selected, maintained, and used according to established standards.

OSHA has specific guidelines, found in the Respiratory Protection Standard (29 CFR 1910.134), which outlines the requirements for respiratory programs, including the assessment of respiratory hazards, medical evaluations for employees required to use respirators, fit testing procedures, and training for employees on proper use and limitations of respiratory protection. By adhering to these regulations, organizations can help ensure a safer environment for their workers, particularly in settings where respiratory hazards are present.

The other entities listed, while also important in their respective fields, do not directly regulate respirator use in the workforce. The National Fire Protection Association focuses on fire safety codes, the Environmental Protection Agency deals with environmental protection and pollution, and the American National Standards Institute develops consensus standards but does not enforce regulations like OSHA does.
