What is one key responsibility of the attendant in a permit-required confined space?

The key responsibility of the attendant in a permit-required confined space is to monitor the safety of the entrant. This role is crucial because the attendant serves as the link between those working inside the confined space and outside emergency responders. By continuously monitoring conditions, the attendant can ensure that the environmental factors remain safe and can quickly identify any potential hazards that may arise. This includes keeping an eye on atmospheric levels, ensuring that the entrant has the necessary equipment, and being prepared to communicate with them at all times.

The attendant is also responsible for sounding alarms or alerting authorities if emergencies occur and for managing the entry and exit of personnel in a safe manner. This monitoring aspect is essential for preventing accidents and ensuring that the work being performed does not endanger the entrant's life or health.
