What operations are specifically prohibited in the vicinity of flammable liquids or combustible materials?

Cutting or welding operations are specifically prohibited in the vicinity of flammable liquids or combustible materials due to the high risk of ignition. Both cutting and welding generate sparks, heat, and molten metal that can easily ignite flammable vapors or materials present in the area. The presence of flammable substances means that any spark can lead to a fire or explosion, posing serious risks to personnel and safety. As such, strict safety standards dictate that these operations must be conducted in designated areas that are free from flammable materials, or appropriate safety measures must be put in place if such tasks must be performed near these hazards.

While other operations like painting, electrical installations, and repairing machinery can also carry some risks, cutting and welding are particularly dangerous because of their direct involvement with open flames and intense heat, making them the operations that need the most stringent controls in potentially hazardous environments.
