Final answer:
The individual responsible for monitoring and ensuring the safety of workers in permit spaces is known as the Attendant.
Step-by-step explanation:
The person stationed outside one or more permit spaces who assesses the status of authorized entrants is known as the Attendant. The primary role of the Attendant is to continuously monitor the safety of the workers inside and ensure the conditions remain safe for entry. They also have emergency duties and must be able to effectively communicate with the authorized entrants and the rescue services if necessary. The Attendant does not enter the space but may perform non-entry rescues if an entrant is in danger. This position is vital for the overall safety of confined space operations.
