This is a picture of a fast food restaraunt after a fire. The fire got into the void space and spread very quickly. Crews were pulled out early and there were no injuries. The building was a total loss.
The focus of this picture is the fall out of from the ceiling. As you can see, when these suspended ceilings fall, many opportunities for entanglement fall with them. A firefighter may not see these hazards because of conditions but are still in danger of being trapped by the fallen materials.
In addition, some of the wires could still be “live” and could energize other conductive materials that have fallen with them. Be aware and prepared. This is why you need tools and a radio when entering hazardous conditions. Stay safe and have a great week.
