Electrical Safety

Electricity can present many dangers for workers, including arc flash hazards. An arc flash occurs when high-amperage currents travel, or “arc,” through the air.

Although injuries from electrical hazards represent a fraction of total on-the-job injuries, they are more likely to result in death than injuries from other causes, according to the Arlington, VA-based Electrical Safety Foundation International.

Electrical hazards cause more than 300 electrocutions and 4,000 injuries in the workplace each year, according to the Rosslyn, VA-based Electrical Safety Foundation International. Many of these incidents could have been avoided with increased awareness about electricity, according to the organization.

Improperly using electrical equipment can create very serious hazards for workers. Special safety features built into equipment often are rendered ineffective when equipment is manipulated or misused.

Inattention to electrical hazards can lead to burns, shocks and electrocution. It is important to always be mindful of any potential electrical risks, both on and off the job.

Between 1992 and 2005 at least 154 workers were killed by electrocution when a metal ladder came into contact with overhead power wires, according to the most recent data available from the Bureau of Labor Statistics.

Jump-starting, testing or inspecting a vehicle battery without taking proper safety precautions could lead to a serious eye injury, warns Chicago-based Prevent Blindness America.

Although it is a commonplace activity on many worksites, charging a lead-acid battery can be an extremely hazardous task. NIOSH identifies a number of associated hazards: the hydrogen gas formed while the battery is charging, the poisonous and corrosive sulfuric acid present in the battery fluid, the possibility of short circuits causing burns or explosions, and the risk of electric shock.
