Hot Work is any work activity which produces an open flame or sparks (e.g., welding, brazing, metal grinding, etc.). Because of this, these activities present a risk of fire in the work area. The Hot Work Safety program attempts to prevent uncontrolled fires through proper work procedures, monitoring, and documentation, and  worker exposure to health and safety concerns. Employees that  perform hot work will need to receive the comprehensive training outlined in this program.
