What is the role of the attendant during permit space entry?

The role of the attendant during permit space entry is to monitor the entry and assist entrants as necessary. This responsibility is critical for ensuring the safety of individuals working within a confined space. The attendant remains outside the permit space and acts as a vital point of communication and support for those inside. They are tasked with monitoring the conditions within the space and ensuring that everyone can safely exit if a hazardous situation arises.

This role involves keeping an eye on the entrants and being prepared to respond to emergencies, which might include calling for help or initiating evacuation procedures. The attendant may also be responsible for maintaining communication with entrants, ensuring that they can relay any issues or needs that arise during the work being performed inside the space.

The other roles outlined in the options do not accurately define the attendant's duties. Entering the space if needed could compromise the safety systems in place, while performing atmospheric testing is typically the responsibility of the entrants or a designated safety professional, not the attendant. Additionally, while supervision is a part of the attendant's role, their primary function does not extend to overseeing all tasks performed inside; their main focus is on monitoring safety and providing assistance as required.
