Electrical Safety Electrical Safety Hazard Overview Solutions Regulations Learn More Hazard Overview What is meant by electrical contact? Electrical contact occurs when a person, object, or equipment makes contact or comes in close proximity with an energized conductor or equipment that allows the passage of current. What is meant by energized? Energized refers to something that is electrically connected to a source of potential difference, or electrically charged so as to have a potential significantly different from that of earth in the vicinity. What are the hazards associated with electrical contact and electricity? Failure to follow basic electrical safety principles can result in equipment and property damage (e.g., due to fire), severe shock and burns, and electrocution. Solutions What can I do to protect myself? Employees should examine cords used to connect equipment for signs of wear, especially missing insulation or exposed wiring. Extension cords with three-prong plugs that are missing grounding pins should be removed from service until the plug can be replaced or a replacement cord obtained. Employees using extension cords in construction-related activities or in wet locations must ensure they have ground-fault circuit interrupter protection. Report to your supervisor any electrical problems you observe while at the workplace. What resources are available to assist employers? Safety and Health Programs The electrical safety-related work practices policy and lockout/tagout program can be downloaded and customized to fit the individual workplace. An example PPE hazard assessment is available and can be customized to fit workplace conditions. Employers are required to perform a workplace hazard analysis to determine what personal protective equipment is necessary to protect employees from continued exposure to identified hazards. Training and Outreach Services The presentations on electrical safety, personal protective equipment (PPE) and lockout/tagout may be useful when dealing with electrical hazards. They can also be modified to meet the needs of the employer's worksite. In addition, the education, training and technical assistance bureau provides free online safety and health training and outreach services (i.e., speaker's bureau requests, safety booths) upon request. Further, the lockout/tagout pre-recorded webinar is available to assist with employee training. Lastly, the NCDOL Library offers free safety and health videos (including streaming video services) and related research assistance on consensus standards (i.e., ANSI, NFPA, NEC). A-Z Safety and Health Topics Related resources can be found on A-Z safety and health topics for lockout/tagout and personal protective equipment for more information. Consultation Services The consultative services bureau provides free and confidential onsite consultation regarding worksite safety and health hazards. Regulations Which standards apply?
