Electrical hazards can cause burns, shocks and electrocution (death).

• Assume that all overhead wires are energized at lethal voltages. Never assume that a wire is safe to touch even if it is down or appears to be insulated.
• Never touch a fallen overhead power line. Call the electric utility company to report fallen electrical lines.
• Stay at least 10 feet (3 meters) away from overhead wires during cleanup and other activities. If working at heights or handling long objects, survey the area before starting work for the presence of overhead wires.
• If an overhead wire falls across your vehicle while you are driving, stay inside the vehicle and continue to drive away from the line. If the engine stalls, do not leave your vehicle. Warn people not to touch the vehicle or the wire. Call or ask someone to call the local electric utility company and emergency services.
• Never operate electrical equipment while you are standing in water.
• Never repair electrical cords or equipment unless qualified and authorized.
• Have a qualified electrician inspect electrical equipment that has gotten wet before energizing it.
• If working in damp locations, inspect electric cords and equipment to ensure that they are in good condition and free of defects, and use a ground-fault circuit interrupter (GFCI).
• Always use caution when working near electricity.

Working with electricity can be dangerous. Engineers, electricians, and other professionals work with electricity directly, including working on overhead lines, cable harnesses, and circuit assemblies. Others, such as office workers and sales people, work with electricity indirectly and may also be exposed to electrical hazards.

Electricity has long been recognized as a serious workplace hazard. OSHA's electrical standards are designed to protect employees exposed to dangers such as electric shock, electrocution, fires, and explosions. Electrical hazards are addressed in specific standards for the general industry, shipyard employment, and marine terminals.

OSHA maintains a listing of the most frequently cited standards for specified 2-6-digit North American Industry Classification System (NAICS) codes. Please refer to OSHA's Frequently Cited OSHA Standards page for additional information. For Construction of Buildings use NAICS code 236, for Heavy and Civil Engineering Construction use NAICS code 237, and for Specialty Trade Contractors use NAICS code 238 in the NAICS search box.

State Standards

There are twenty-eight OSHA-approved State Plans, operating state-wide occupational safety and health programs. State Plans are required to have standards and enforcement programs that are at least as effective as OSHA's and may have different or more stringent requirements.
