Which three positions are identified by OSHA to handle confined space operations?

The correct answer identifies three essential roles that OSHA has established for effectively managing confined space operations: entry supervisor, entrant, and attendant. Each of these roles is critical for ensuring safety and compliance during confined space work.

The entry supervisor is responsible for overseeing the entire operation, ensuring that all safety protocols are followed, and that the environment is suitable for entry. This person's role includes assessing the risks, approving entry permits, and ensuring that everyone involved understands their responsibilities.

The entrant is the individual who physically enters the confined space. This person must be trained to recognize hazards within the space and is typically equipped with necessary personal protective equipment. The entrant must also understand how to communicate with the attendant and respond to any emergency situations.

The attendant plays a crucial role outside the confined space. This individual monitors the activities of the entrants, maintains communication, and is alert for any signs of distress or emergencies. The attendant is responsible for alerting the proper authorities and initiating rescue procedures if necessary.

In contrast, the other options involve roles and responsibilities that do not align with OSHA’s specifically identified positions for confined space operations, which is why they do not represent the standard established for such environments.
