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.

The references on this page provide information related to electrical in construction including OSHA's electrical construction regulations, hazard recogition, possible solutions and general resources.

OSHA Standards

This section highlights OSHA standards, frequently cited standards, Federal Register notices (rules and proposed rules), directives (instruction to OSHA staff), and letters of interpretation (official letters of interpretation of the standards) related to electrical hazards.

Electrical hazards are addressed in specific standards for the construction industry. For additional information on general industry regulations, see the general industry regulations section.

Visit the Electric Power Generation, Transmission and Distribution Standard Page for information on the final rule.

Frequently Cited Standards

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.

Hazard Recognition

Many workers are unaware of the potential electrical hazards present in their work environment, which makes them more vulnerable to the danger of electrocution. According to 29 CFR 1926.21(b)(2), "The employer shall instruct each employee in the recognition and avoidance of unsafe conditions and the regulations applicable to his work environment to control or eliminate any hazards or other exposure to illness or injury." The following references aid in recognizing hazards associated with electrical work.

Possible Solutions

A variety of possible solutions may be implemented to reduce or eliminate the risk of injury associated with electrical work. Examples of solutions include the use of insulation, guarding, grounding, electrical protective devices, and safe work practices. The following references aid in controlling electrical hazards in the workplace.
