Electrical Safety
National Summary

This topic covers OSHA’s electrical safety regulations for general industry and for construction workplaces.

The general industry rules are divided into two major categories: design safety standards and safety-related work practices. The regulations cover electrical installations and equipment installed or used within or on buildings, structures, and other premises. OSHA’s safe work practice rules for electricity provide standards for both qualified employees (those with a specific level of training) and unqualified employees (those with little or no training) who work on, near, or with various electrical components.

OSHA's electrical standards for construction work (i.e., construction, alteration, or repair) cover the hazards that expose construction employees to such dangers as electric shock, electrocution, fires, explosions, and falls.

For related resources and training materials, refer to the following topics:

  • Lockout/Tagout for information on OSHA regulations for hazardous energy control programs
  • Electric Power Generation for information on OSHA regulations for electric power generation and distribution systems
