The standard that mandates the use of backup teams in incidents where operations are conducted in an Immediately Dangerous to Life or Health (IDLH) atmosphere is 1910.134. This specific regulation outlines the requirements for respiratory protection and establishes protocols for ensuring the safety of personnel operating in hazardous environments.

Under OSHA’s 1910.134 standard, if firefighters or emergency responders are working in an IDLH atmosphere, they must have a team standing by to provide assistance if needed.
