Which activity requires the implementation of a hot work program?

The implementation of a hot work program is specifically required for hot work operations because these activities involve sources of ignition, such as open flames or sparks, which significantly increase the risk of fire and explosion. Hot work includes tasks like welding, cutting, grinding, and soldering, all of which can inadvertently ignite flammable materials in the vicinity.

A hot work program establishes safety procedures, monitoring protocols, and protective measures to minimize risks during these operations. This may include ensuring safe distances from flammable materials, using fire-resistant blankets, and having fire extinguishing equipment readily available. Furthermore, a permit system might be involved to ensure that all safety precautions are taken before beginning hot work, thus protecting workers and the facility from potential hazards.

In contrast, the other activities mentioned do not inherently pose the same level of risk for igniting a fire, therefore, they do not necessitate a hot work program in the same way.
