Electrical hazards
['HAZWOPER']
- Employers should minimize electrical hazards to workers by identifying and deenergizing circuits workers might contact and communicating about potential dangers.
- Power line and lightning hazards also pose risks to site employees working outdoors.
Electrical equipment
Electrical equipment used onsite may also pose a hazard to workers. To help minimize this hazard, low-voltage equipment with ground-fault circuit interrupters and watertight, corrosion-resistant connecting cables should be used onsite.
Capacitors
An additional electrical hazard involves capacitors that may retain a charge. All such items should be properly grounded before handling. OSHA standard 29 CFR 1910.137, Electrical Protective Equipment, describes clothing and equipment for protection against electrical hazards.
Power lines
Overhead power lines, downed electrical wires, and buried cables all pose a danger of shock or electrocution if workers contact or sever them during site operations.
Electrical lines should be assumed to be energized until proven otherwise. Lines and other conductors may become reenergized without warning as utilities are evaluated and restored after an emergency release or other disaster.
Employers should:
- Identify the location of any energized electrical power circuit that employees (or their tools and equipment) could contact;
- Deenergize and ground any such circuits; and
- Post signs and advise individuals of the location, hazards, and protective work practices.
More information is provided in the Occupational Safety and Health Administration (OSHA) fact sheet, Working Safely Around Downed Electrical Wires, found at www.osha.gov/OshDoc/data_General_Facts/downed_electrical_wires.pdf.
Lightning
In addition, lightning is a hazard during outdoor operations, particularly for workers handling metal containers or equipment. To eliminate this work hazard, weather conditions should be monitored, and work should be suspended during electrical storms.
