OSHA testing requirements include initial and periodic hearing tests for employees enrolled in hearing conservation programs, fit testing of respiratory equipment and skin testing for employees who risk exposure to tuberculosis, and periodic testing of fire safety equipment. Employees enrolled in a hearing conservation program must have a hearing test called an audiogram upon starting work to establish their initial hearing levels and undergo annual tests thereafter to assess the degree of hearing loss that may be work-related.
Hearing conservation programs are required when employees engage in work where noise levels average over 85 decibels over eight hours, where the maximum noise level exceeds 115 decibels or where the peak noise level exceeds 145 decibels.
OSHA also requires workers in health and medical care facilities, correctional institutions, homeless shelters, long-term care facilities and drug counseling centers who are at risk for exposure to tuberculosis to perform annual fit tests on respirators to ensure they provide protection against possible infections. OSHA also requires that for facilities in which the risk of exposure to tuberculosis exists; workers undergo medical abatement practices that include initial skin tests for tuberculosis, and periodic tests every three months for workers at high risk of exposure, every three months for workers with intermediate risk of exposure, and annually for workers with low risk of exposure. Additionally, OSHA requires inspectors to perform tests such as smoke-trail visualization tests to confirm negative pressure isolation in facilities at risk for developing tuberculosis outbreaks.
OSHA also requires periodic testing of fire extinguishers, sprinklers, fire doors and other fire safety equipment.
