Installing properly certified infrared (IR) windows to inspect switchgear and motors can make it easier for companies to comply with the U.S. NFPA 70E Standard for Electrical Safety in the Workplace. IR windows allow technicians to inspect electrical equipment without removing the panel cover (the cause of more than 99 percent of arc blast incidents).
Infrared windows provide a solid barrier between the thermographer and the live conductors. By design, it is possible to reduce the trigger effects of an arc, but also provide a far safer working environment. Additional safety applications include:
Moving safety programs from reactive to proactive
Inspecting energized components with the panel door closed
Increasing speed of inspections
Ensuring only trained and authorized people can remove the IR window to complete an inspection or scan
Whether workers use IR windows to take thermal images or inspect equipment, IR windows increase worker safety under potentially hazardous conditions. When it comes to IR windows, durability matters. Be sure to find windows that are capable of withstanding arc blasts, realizing that durability can change over time.
