Hot work can be defined as any operation such as brazing, cutting, welding, grinding, soldering, or torching that can cause sparks or flames.
Hot work often arises from construction and/ or maintenance activities. Hot work is work that might generate sufficient heat, sparks or flame to cause a fire. Hot work includes welding, flame-cutting, soldering, brazing, grinding and other equipment incorporating a flame, e.g. tar boilers, etc. Hot work can be very dangerous and stringent controls must be in place.
