What should workers do with holes in walls when welding?

Covering holes in walls while welding is essential to prevent the escape of sparks, molten metal, and slag that can result from the welding process. This is crucial for maintaining safety and minimizing fire hazards, especially in environments where flammable materials may be present. By covering the holes, workers help contain any debris generated during welding and protect individuals in surrounding areas from potential injury.

Leaving holes uncovered may seem beneficial for ventilation, but it exposes the area to risks associated with welding activities. Ignoring the holes or making no modifications overlooks the fundamental principle of maintaining a safe working environment. Proper safety practices dictate that all potential sources of fire hazards, including openings in walls, should be addressed effectively to ensure the protection of both the workers and the workspace.
