Which of the following is a responsibility of a supervisor during a permit-required confined space entry?

• A. Verify a permit has been issued
• B. Monitor atmosphere and entrants
• C. Ensure rescue readiness
• D. All of the above

Answer: (D)

The main idea here is that the supervisor oversees the entire permit-required confined space entry to ensure all safety controls are in place and followed. Verifying a permit has been issued means confirming that a valid entry permit exists, outlining the hazards, required precautions, and conditions for entry. Monitoring the atmosphere and entrants ensures that oxygen levels and any toxic or combustible gases are checked and kept within safe limits, with ongoing oversight of the entrants’ status and communications. Ensuring rescue readiness means having trained rescuers and the appropriate equipment ready and a rescue plan in place and executable if conditions change or an emergency occurs. Because all of these elements are essential to a safe entry, the best choice is that all of the above.
