Which of the following is NOT a duty of attendants in a work environment?

The role of attendants in a work environment, particularly in confined spaces, involves specific responsibilities designed to ensure the safety and monitoring of workers who are entering and exiting potentially hazardous environments. Among these responsibilities, attendants are required to communicate effectively with entrants, maintain an accurate count of how many individuals are inside the confined space, and monitor all activities happening both inside and outside of the space.

Operating heavy machinery is not a duty typically assigned to attendants. Their focus is on safety and communication rather than on tasks that require operating equipment, which is generally the responsibility of qualified operators. This distinction helps to ensure that attendants can concentrate on monitoring the condition of entrants and react promptly to any emergencies without being distracted by the operation of machinery.
