Who must sign the confined space entry permit before entering a permit-required space?

• A. Entry supervisor
• B. Employee
• C. Safety officer
• D. Plant manager

Answer: (A)

The main idea is that a permit-required confined space entry is only authorized by the person in charge of the entry—the entry supervisor. That role has the authority to confirm that all safety measures are in place before anyone enters, including isolating the space, completing and reviewing atmospheric testing, ensuring a rescue plan and equipment are ready, and assigning an attendant and entrants who understand the hazards and procedures. The entry supervisor’s signature documents that these controls have been reviewed and are in effect for the permit’s duration, making entry permissible. The other roles—an employee, a safety officer, or a plant manager—don’t have the authority to authorize entry into that space through the permit, though they may contribute to the process in other ways.
