Electricity, it’s a common and potentially hazardous source of energy found in the workplace. Shock is the most obvious hazard associated with electricity, but serious injury or death can also result from exposure to arc flash and arc blast. Workers exposed to these hazards risk electrocution, severe burns,hearing and sight damage, internal injuries, etc. Because of these risks, electrical safety is becoming an increasingly important topic of conversation.
The surest way to prevent injury is to eliminate exposure to the hazardous electrical energy. This is normally achieved using a lock-out tag-out (or LOTO) procedure to disconnect or “isolate” a machine from its power source. Practical guidance on LOTO programs & procedures can be found in the Canadian Standards Association CSA Z-460. Control of Hazardous Energy – Lockout and other methods. Certain work like trouble shooting and testing, however, can only be performed while equipment is live.
Anytime an electrical box or panel is opened while the power is on, live work is being performed. Working live significantly increases exposure to shock, arc flash and arc blast hazards. Special tools, protective equipment, training and procedures are needed to reduce risk and prevent injury. The National Fire Protection Association NFPA 70E Standard for Electrical Safety in the Workplace provides the guideline for live electrical work in the United States. In Canada, CSA Z-462 “Workplace Electrical Safety” parallels NFPA 70E standard.
