Summary

The speakers review recorded statistics on nonfatal electrical injuries in the U.S. private industry from 1996 to 2020.

• The figures may undercount injuries. They include recorded incidents, but some workers may not report a shock or complete the required paperwork.
• Recorded nonfatal injuries declined over time. The speakers describe a rise from 1996 to 1999, reaching just over 4,000 injuries, followed by a downward trend to just over 2,000 by 2020. They suggest that training, improved personal protective equipment (PPE), safer tools and meters, and advances in equipment may have contributed to the decline. However, safer equipment only helps when people know how to use it properly.
• Electric shock is the most common injury category, but electrical burns also make up a substantial share. Burns can occur when current passes through the skin and heats it, or from an arc flash, which can cause severe burns across large areas of the body. The speakers caution against treating even a “minor” shock as an inevitable or harmless part of working around electricity.
• Construction has the largest share of injuries among the sectors discussed. Manufacturing also involves substantial exposure. Other sectors mentioned include business services, education, health services, leisure and hospitality, retail trade, and other industries.
• Electrical injuries are not limited to electricians. Painters, roofers, and workers using ladders or scaffolding may also be exposed, including workers who are not supposed to work on electrical systems.
• Risk varies by work environment. Jobs and industries involving more contact with electrical equipment naturally create more opportunities for exposure.
