Finding Electrical Hotspots Before They Turn Into Fires: The Role of Thermographic Scanning

Bangladesh Fire Service and Civil Defense officials believe that a majority of fires in RMG factories occur due to electrical faults and malfunctions. For this reason, the Alliance places a high priority on remediating electrical hazards as a means of preventing disasters like those that have plagued the industry in the past.

Infrared imaging – also known as thermographic scanning – is the most effective tool available to our engineers for identifying urgent electrical risks. IMG_4608Unlike conventional cameras, infrared scanners capture radiation and produce images that show the relative temperature of electrical equipment. At a minimum, there are 40 types of electrical equipment that should be scanned (if found onsite), such as fuse boxes, water and vacuum pump electrical systems, and fan and coils panels. The greatest concerns arise when we see the largest temperature differential. Regular scans of all equipment should be done every few years, though the required frequency of this task may increase based on past incidence of hotspots. (more…)
