Front-line technicians can safely scan electrical equipment with a thermal imager in two ways: by leaving the panel closed and scanning through a specialized infrared window or by opening the electrical panel while wearing all of the required personal protective equipment (PPE).

Depending on the arc-flash rating of the equipment, PPE could include but is not limited to protective clothing, gloves, and a face shield. Most arc-flash events happen because of a change in state of the equipment, such as opening a piece of equipment to scan it.

By installing infrared windows, technicians can scan electrical equipment more frequently and safely, as well as without being forced to change the state of the equipment.

Whichever way managers choose, the maintenance staff must understand and adhere to requirements of National Fire Protection Association 70E, Electrical Safety in the Workplace.
