What defines hotwork?

Hotwork is specifically defined as any activity that generates a flame or creates temperatures exceeding 400°F. This definition is crucial because hotwork operations, such as welding, cutting, grinding, or brazing, pose significant fire hazards, particularly in environments where flammable materials are present.

The threshold of 400°F is established because at this temperature, the risk of ignition increases significantly, and proper safety measures must be in place to mitigate these risks. Understanding this definition helps ensure that safety protocols and precautions are strictly followed during such work to prevent potential fire incidents.

While producing sparks or temperatures above a certain degree might seem relevant, they do not encompass the full spectrum of risks associated with hotwork. The emphasis on flame generation or high temperatures provides a clear and specific guideline for understanding the boundaries and potential dangers associated with hotwork activities.
