Anywhere from 5 to 10 arc flash accidents occur every day in the U.S., resulting in severe burn injuries that affect over 2,000 workers annually. The costs in lives, livelihoods, and liability claims can be enormous. Fortunately, new FLIR IR Windows now offer a solution to help reduce exposure so you can perform scans safely, more efficiently, and confidently that comply with NFPA 70E requirements.

  • Easy Installation – Only one hole to drill and FLIR's single PIRma-Lock™ ring nut to tighten; same design as conduit connections that use standard US punch tools
  • PIRma-Lock™ Reliability – Tried and true locknut technology makes FLIR's IR Windows' self-grounding locking ring an IR windows first, with teeth that bite tight to the inside of the panel
  • Quick Access Hinged Cover – IR Windows' simple flip-open cover with integrated equipment ID label stays permanently attached so it never gets dropped, mismatched, or lost
  • Broadband Transmission – Crystal lens supports short, mid, and longwave IR cameras, visual inspections, and fusion technology; allows FLIR cameras with integrated lamps to capture video documentation

Determine the Correct Protection Level, To evaluate Fire Retardant clothing materials in order to measure the heat transferred through the fabric, two values are calculated: Arc Thermal Performance Value (ATPV)...the minimum energy causing the predicted onset of second-degree burns and Heat Attenuation Factor (HAF)...the percentage of total energy of the arc that the fabric prevents from passing through, OSHA requires that each employer must assess the potential hazards in the work environment and determine the appropriate clothing materials using ASTM PS57-97. Always do a hazard assessment. You will need to know electrical system voltage, fault current available, number of phases, Arc time duration, estimated Arc gap, minimum distance from the Arc, and Arc configuration.
