Which statement about opening hollow drums before work is accurate?

• A. It is not necessary to open and vent hollow containers before working on them
• B. It is mandatory to open every container before welding
• C. Only unempty containers require opening
• D. Containers should be opened only after welding starts

Answer: (A)

Opening hollow drums before work is about making sure there aren’t flammable vapors or built‑up pressure inside. In some safety practices, if a hollow container has been properly drained, cleaned, and verified to be free of hazardous vapors, you can proceed without forcing an opening and venting step. The idea is to assess the actual contents and condition of the drum rather than apply a blanket rule to every hollow container. If a drum is known to be empty and safe, venting may not be necessary before working on the shell. The other statements imply universal requirements that aren’t always appropriate. Saying you must open every container before welding is overly prescriptive and can be unnecessary if the container has been confirmed safe. Claiming that only unempty containers require opening ignores the possibility that even some empty-looking containers can still hold hazardous vapors or residues. Waiting to open until after welding starts creates a real risk of ignition or vapor buildup.
