Electrocution

Occupational hazard analysis

Recognize

Electric shocks and electrocution are thought to be the main risks involved with electrical work. In the US, there were nearly 6000 fatal cases of electrocution between the years of 1992 and 2013, and 24,100 non-fatal injuries between 2003 and 2012. Clearly this is a concerning hazard we should try to better control.

Evaluate

The risk of electrocution depends on many factors, including the current, voltage, duration, and pathway of the shock. Symptoms usually include burns. Depending on the pathway, the shock can cause neurological effects, especially to the heart and lungs. If it passes through the heart ventricular fibrillation may be induced, which can be lethal.

Control

Often employees working within an electric cabinet are wearing proper protective equipment, but others helping or in the surrounding area are not. These people should also be wearing the appropriate equipment as an electrical arc can reach up to 10 feet from its source.

It is also recommended that facilities should plan ahead to prevent workplace accidents. This includes ensuring all equipment is properly maintained and tested, there is a employee education and health program in place, and adequate supervision is provided. Additionally, older facilities (ex. a power plant) should be upgraded when necessary.

As electrical workers will frequently put themselves at risk of electrocution, anyone in a hazardous situation should wear protective equipment. This include flame resistant clothing, safety goggles, hard hats, and gloves.
