Final answer:
An authorized entrant must exit a confined space when ordered by the entry supervisor to ensure workplace safety and adherence to hazardous environment protocols.
Step-by-step explanation:
The authorized entrant has a few responsibilities, including exiting a confined space when ordered by the entry supervisor. This responsibility ensures safety within the workplace and is a precaution in environments that can be hazardous. The entrant must always be prepared to evacuate either upon direct order from the supervisor or if alarm systems are activated, signaling a potential danger. It's important for an entrant to understand all safety protocols, including the conditions that require immediate exit, such as the presence of an atmospheric hazard, a warning from a worker outside the space, or a malfunction in safety equipment.
