Transferring tank to loading rack requires ________ COF HOLDER.

Transferring tank to loading rack requires ________ COF HOLDER.

• A. NONE
• B. TWO
• C. THREE
• D. ONE

Answer: (D)

Transferring from a tank to the loading rack is a controlled operation that requires clear authorization from a trained supervisor. A single COF holder is designated to oversee the transfer, carrying the Certificate of Fitness and ensuring all safety steps are in place before and during the process—grounding/bonding, valve alignment, alarms and interlocks, and clear communication with rack personnel. Having one person responsible provides a clear point of authority, reduces the risk of conflicting actions, and allows a quick stop if anything goes wrong. None would leave the operation without proper supervision, while having two or three COF holders would add unnecessary complexity and potential confusion. So, the required number is one COF holder.
