Who can authorize opening and entry into IDLH spaces?

• A. CO
• B. XO
• C. CDR
• D. CNO

Answer: (A)

Opening and entry into IDLH spaces carry life-safety implications that require the highest level of authority. The Commanding Officer has the ultimate responsibility for the ship’s safety and mission readiness, so they are the person who can authorize access after ensuring a proper entry plan, permits, and safety measures are in place. The CO can delegate this authority in writing to a qualified individual, but the authority originates with the CO. Other ranks may oversee or implement safety procedures, but they do not hold the final say to authorize entry into an IDLH space.
