A thermal oil system has been contaminated and needs draining for cleaning. The written procedure tells you to open the drain valve but doesn't specify a cooling-down period or PPE. What should you do?
A. Treat the gap as a hazard in its own right: apply a suitable cooling/depressurising period and full PPE before proceeding, and raise the procedure gap with the Chief Engineer
B. Delegate the task to a junior rating without further briefing, since the procedure covers it
C. Skip the task until a class surveyor is on board
D. Follow the procedure exactly as written — if it doesn't mention cooling or PPE, they're not required
