Which federal agency requires medical screening and fit testing of SCBA?

The requirement for medical screening and fit testing of Self-Contained Breathing Apparatus (SCBA) falls under the jurisdiction of the Occupational Safety and Health Administration (OSHA). This federal agency is responsible for ensuring safe and healthy working conditions by setting and enforcing standards, as well as providing training, outreach, education, and assistance.

Specifically, OSHA standards mandate that employers must provide their employees with proper respiratory protection when necessary, which includes conducting medical evaluations to determine the fitness of employees to use respirators, as well as fit testing to ensure that the respirators provide an adequate seal. This is vital for the safety of firefighters and other emergency personnel who rely on SCBA for protection against hazardous environments.

In contrast, other agencies like the Environmental Protection Agency (EPA), the Centers for Disease Control and Prevention (CDC), and the National Institute of Standards and Technology (NIST) have different roles and responsibilities that do not specifically focus on the testing and screening aspects required under the OSHA standards.
