Who must authorize and sign the entry permit for confined space entry?

The requirement that the confined space entry permit must be authorized and signed by the CSE (Confined Space Entry) supervisor is crucial for ensuring that all safety protocols are followed before anyone enters a confined space. The CSE supervisor has the expertise and responsibility to assess the risks associated with the entry, review the safety measures implemented, and confirm that all necessary precautions, such as air quality monitoring and hazard mitigation, are in place.

This supervisory role is vital not only for compliance with OSHA regulations but also for the health and safety of all personnel involved. The supervisor's knowledge of the specific hazards that might be present in the confined space and their authority to enforce safety measures enable them to make informed decisions about when it is safe to proceed with the entry.

The other roles, such as the safety officer, entrants, and equipment operators, while important in the overall safety plan, do not hold the final authority to authorize the entry; thus, they do not fulfill the requirements outlined in OSHA standards regarding confined space entry permits.
