The COF holder should ensure valves do not leak and are easily what?

• A. Operable
• B. Sealed
• C. Accessible
• D. Lubricated

Answer: (A)

Valves must be easily operable. Being able to open and close a valve without difficulty is essential for quickly isolating oil flow during normal operations or in an emergency, which helps prevent spills and reduce hazards. If a valve leaks, containment is already compromised, but even a non-leaking valve that is hard to operate can delay shutdown and worsen an incident. The other options don’t address the action needed in practice: sealing relates to preventing leaks but not to the ability to operate; accessibility is about physical location rather than functional use; lubrication is a maintenance detail, not the primary safety requirement.
