Since the 2004 revision of the NFPA-70E there has been a requirement to develop workflow processes that mitigate against the risk of exposure to arc flash explosions. Among the myriad of measures employed to protect qualified personnel from these risks has been the application of infrared windows and viewports. This webinar is intended to educate and edify end users on the strengths, weaknesses, opportunities, and threats to utilizing these devices. Their use is not as simple as it many times is presented and understanding their function and limitations can mean the difference between success and failure. This webinar is a must for people before purchasing and installing the windows, as well as after installation and how to collect the best data you can with your thermal imager.
