What type of equipment is categorized as hot work equipment?

Hot work equipment refers to tools and devices that can generate sparks or flames, thus posing a fire hazard during their operation. Electric or gas welding tools fall into this category because they produce high heat and molten metal during the welding process, which can ignite flammable materials nearby.

In contrast, office computers, portable heaters, and construction lifting machines do not generate heat or sparks in a manner that directly contributes to fire hazards in the same way that welding tools do. Office computers are used for information processing, and while they may overheat if malfunctioning, they are not typically associated with hot work operations. Portable heaters can produce heat but are generally not categorized under hot work as they are not involved in processes that result in open flames or sparks like welding. Construction lifting machines focus on hoisting and moving materials and do not involve activities that lead to fire risks associated with hot work.
