BOpen the water drum manhole before opening the steam drum manhole.

DRemove handhole plate dogs with a slugging wrench.
AI Explanation

The correct answer is A) Wire all valves closed that connect to other boilers. Wiring all valves closed that connect to other boilers is considered a safe practice when opening and inspecting the waterside of a boiler. This prevents the inadvertent release of steam or hot water from the connected boilers, which could pose a serious safety hazard to the personnel performing the inspection. The other options are not considered safe practices. Opening the water drum manhole before the steam drum manhole (B) could lead to a sudden release of steam, and ventilating the waterside until completely dry (C) is not necessary for a safe inspection. Removing handhole plate dogs with a slugging wrench (D) could be unsafe and is not a recommended procedure.
