What are the three duties of personnel in a Confined Space entry?

The correct identification of the three duties of personnel in a confined space entry pertains to specific roles that ensure safety during such operations. These roles include authorized entrants, attendants, and entry supervisors.

Authorized entrants are individuals who have the permission and training to enter confined spaces. They are responsible for monitoring the environment and their own safety while performing tasks inside the space. This role is critical because it ensures that only trained personnel are exposed to the potential hazards that may exist in confined spaces.

Attendants are responsible for monitoring the activities of the authorized entrants from outside the confined space. Their role is crucial for maintaining communication and ensuring the safety of entrants by being prepared to act in case of an emergency. Attendants are tasked with keeping track of the conditions in and around the confined space, providing a crucial link between the entrants and the entry supervisor.

Entry supervisors hold the responsibility for overseeing the entire confined space entry operation. They ensure that proper safety protocols are followed, that all necessary equipment is in place, and that the atmospheric conditions are monitored. The supervisor's role is vital for coordinating the entry and ensuring compliance with safety regulations.

The combination of these three roles — authorized entrants, attendants, and entry supervisors — forms a comprehensive approach to safely managing confined space entries, thereby providing
