What is the role of a "spotter" in confined space operations?

The role of a "spotter" in confined space operations is primarily to monitor the safety of entrants from outside the space. This involves being vigilant about the conditions inside the confined space, ensuring that safety protocols are followed, and providing immediate assistance or communication in case of an emergency. The spotter watches for any signs of distress or hazardous conditions that the entrants may be unable to detect themselves due to the nature of the confined space, such as low visibility or limited access to outside help.

In this context, while various roles and responsibilities within confined space operations are critical for safety, the specific task of monitoring by the spotter is essential to maintain an awareness of the situation and act promptly if needed. This role is complementary to others involved in the operation, such as those who manage entry permits or perform atmospheric tests, but the spotter's immediate focus is on the safety and well-being of those inside the confined space.
