Before any welding can take place in one of his/her vessels, what must a power engineer ensure?

Before any welding can occur on a vessel, a power engineer must ensure that the equipment is isolated and free of combustibles. This is crucial for safety reasons. Welding produces sparks and heat, which can ignite flammable materials and lead to dangerous fires or explosions. By isolating the equipment, the power engineer ensures that there are no live electrical connections or pressurized systems that could become hazardous during the welding process.

Additionally, removing combustibles from the area minimizes the risk of ignition. This step is a fundamental part of safety protocols in any operation involving welding, especially in confined spaces or near flammable materials. Ensuring a safe working environment is the primary responsibility of the power engineer prior to commencing welding activities.
