What authority does OSHA have regarding exposure limits?

The correct answer centers on the authority of OSHA (Occupational Safety and Health Administration) in relation to workplace safety and health. OSHA is responsible for setting and enforcing regulations that ensure safe and healthy working conditions. This includes the authority to issue citations for violations regarding workplace safety standards.

OSHA specifically establishes permissible exposure limits (PELs) for various hazardous substances, including anesthetic gases. However, it does not adopt standards directly from NIOSH (National Institute for Occupational Safety and Health); rather, it operates independently, often using NIOSH recommendations as guidance. Therefore, the option that implies OSHA can issue citations when there is non-compliance with the standards it has set is accurate, considering its regulatory authority. This reflects OSHA's role in maintaining workplace safety by enforcing compliance with its own established standards in various industries, including veterinary practices.

In terms of the other options, while OSHA does provide regulations regarding safety procedures, it does not set its own exposure limits for anesthetic gases nor does it have the authority to regulate based on NIOSH standards. Additionally, stating that OSHA does not regulate any exposure limits is incorrect, as it explicitly does so through its established guidelines.
