What activities are included in the definition of hot work?

Hot work refers to any tasks that generate heat or sparks, which can pose a fire hazard in environments with flammable materials. Cutting and welding are classic examples of hot work because these processes involve high temperatures that can ignite combustible materials nearby. The use of tools like torches and welders produces intense heat, which is why proper precautions and safety measures are vital when performing these tasks in potentially hazardous areas.

In contrast, the other activities listed, such as painting and cleaning, electrical work, or installing and assembling, generally do not produce the same level of heat or sparks associated with cutting and welding, and therefore, do not fall under the same risk category. These tasks may involve their own risks, but they do not carry the specific incendiary risks associated with hot work.
