Which of the following roles does NOT participate directly in confined space entry operations?

The rescue team does not participate directly in confined space entry operations because their primary role is to be on standby in case an emergency occurs. Their involvement is crucial for ensuring the safety of the entrants, but they do not enter the confined space themselves during regular operations. They are trained to respond to incidents and provide assistance, but their actions are activated only if an entrant is in distress or an emergency arises, rather than during the actual entry process.

In contrast, the entry supervisor is responsible for overseeing the entire situation, ensuring that safety protocols are followed, and that all participating personnel are adequately trained and equipped. The entrant is the individual who physically enters the confined space to perform work. The attendant remains outside the confined space, monitoring the situation and maintaining communication with the entrants to ensure their safety. Each of these roles has direct involvement with the entry operations, whereas the rescue team's function is preventive in nature.
