Who is responsible for confirming that conditions remain consistent with the permit during a confined space operation?

The entry supervisor is responsible for confirming that conditions remain consistent with the permit during a confined space operation. This role is crucial for ensuring the safety of all personnel involved in the operation. The entry supervisor has the authority and responsibility to perform a comprehensive evaluation of the confined space conditions before the entry and continuously monitor those conditions throughout the operation.

The entry supervisor's duties include reviewing and understanding the permit, verifying that all safety measures are in place, and ensuring that the air quality and atmospheric conditions remain within acceptable limits as specified in the permit. This oversight helps prevent incidents that could arise from changing conditions within the confined space.

While the attendant, who is on-site to monitor the safety of entrants, has an important role in observing and reporting any unsafe conditions, it is ultimately the entry supervisor who is in charge of making sure that all safety protocols are being adhered to and that the operation stays within the parameters set forth in the permit. The other roles, such as the entrant and backup entrant, have specific duties focused on executing the tasks inside the confined space, but do not hold the overall responsibility for monitoring and confirming compliance with safety conditions.
