Hazardous Energy Control refers to the procedures and practices used to prevent accidental release of energy during maintenance or servicing of equipment. This includes controlling various forms of energy such as electrical, mechanical, hydraulic, and thermal energy. Proper control measures ensure that machines are safely shut down and cannot be restarted unexpectedly, protecting workers from potential injuries. The process typically involves Lockout/Tagout (LOTO) procedures, where energy sources are isolated and locked to prevent operation. Workers place tags on equipment to indicate that it is not to be used until maintenance is complete. This systematic approach is essential for workplace safety.
