The Occupational Safety and Health Administration, or OSHA, requires employers to have a respiratory protection program that contains policies and procedures to prevent exposure to airborne infectious disease. Your organization’s respiratory protection program requires you to have fit testing, so you know how, when, and what type of particulate respirator to use. Understanding the proper fit and use of particulate respirators is vital to ensure you are fully protected. This course discusses fit testing and how to use and perform a seal check for a particulate respirator.
