Chapter 22: Hot Work Safety
Hot jobs are those that involve operations that can generate sparks, flames or enough heat to start a fire or explosion. These activities include welding, cutting, brazing, grinding, circular sawing, and other forms of work that involve the use of power tools or the generation of heat. This chapter provides guidance on how to perform these jobs safely and effectively.
Risk Identification
Before starting any hot work, it is essential to identify all associated risks. This may include the presence of flammable or combustible materials, the possibility of ignition of gases or vapors, exposure to high temperatures, and the possibility of injury from sparks or molten metal spatter. A proper risk assessment must be carried out and documented before any hot work begins.
Risk Control
Once risks are identified, measures must be taken to control them. This may include removing flammable materials from the work area, providing adequate ventilation to remove gases or vapors, using appropriate personal protective equipment (PPE) such as safety glasses, heat-resistant gloves and aprons, and implementing safe work procedures.
Safe Work Procedures
Safe work procedures are an essential part of hot work safety. They should include steps for safely preparing the work area, using equipment correctly, observing all safety precautions, regularly checking the work site for any new hazards, and properly cleaning up after work is completed. These procedures must be followed strictly at all times.
Personal Protective Equipment
Proper use of PPE is vital to safety in hot work. This may include safety glasses to protect eyes from sparks and molten metal spatter, heat-resistant gloves to protect hands, heat-resistant aprons or clothing to protect the body, and safety shoes to protect feet. Workers must be trained in the correct use of PPE and it must be maintained in good working order.
Training and Supervision
Proper training is crucial to hot work safety. Workers must be trained in correct hot work techniques, proper use of PPE, and hazard identification and control. In addition, adequate supervision must be provided to ensure that safe work procedures are followed and that any emerging risks are promptly identified and controlled.
Conclusion
In summary, hot work safety is a matter of identifying and controlling hazards, following safe work procedures, wearing the proper PPE, and receiving proper training and supervision. By following these guidelines, hot work can be carried out safely and effectively, minimizing the risk of fire, explosion and injury.
