Which standard mandates the use of backup teams at incidents where operations are conducted in an IDLH atmosphere?
Correct Answer:
OSHA 1910.134
Explanation:
In environments that are immediately dangerous to life or health (IDLH), the OSHA Respiratory Protection Standard requires having a backup attendant available to monitor and assist the respirator user and to perform a rescue if the wearer cannot safely exit. This standby arrangement is built into the respiratory protection program to ensure rapid response in case of equipment failure, loss of air, or any distress while operating in hazardous atmospheres. Because this protection and rescue requirement is specifically tied to respirator use in IDLH conditions, this standard is the one that mandates backup teams. The other listed standards cover different topics and do not specifically mandate standby rescue personnel for IDLH entries.
