Engineering Controls

Before workers are required to perform tasks with electrical equipment, control measures can be applied to reduce the risk of arc flash events. Design elements that ensure thorough insulation of the equipment and reduce the amount of time that an arc flash can continue are effective in lessening the potential injuries these events present.

Design option decisions should allow the ability to eliminate hazards or reduce risk by doing the following:

• Reducing the likelihood of exposure
• Reducing the magnitude or severity of exposure
• Enabling the application of an electrically safe work condition
