Which of the following is a responsibility of the attendant in a confined space?

The primary responsibility of an attendant in a confined space is to monitor air quality, which includes ensuring that the atmosphere is safe and within acceptable limits for the people working inside. This is crucial because confined spaces can contain hazardous gases, insufficient oxygen levels, or other dangerous conditions that may suddenly arise. The attendant must be vigilant, continuously checking the air quality and being aware of any signs of distress or hazards that may indicate a need for immediate action.

While performing rescues and providing first aid are critical safety roles, they typically fall under the responsibilities of trained rescue personnel rather than the attendant specifically. The attendant's main function is to act as a watchful observer and communicator, facilitating help if needed but not necessarily engaging in rescue efforts. In this context, the focus of the attendant's duties is primarily on monitoring the environment and ensuring the safety of those working inside the confined space.
