For example, I was once up a ladder, working on getting power to a sign for a new Chinese restaurant. A passer-by wasn't about to accept my answer that I was just the sign guy, I had no idea when they would open, etc. Their endless questions continued to interfere with my work, when they asked what would be on the menu (!!) Well, in finest form, I replied that they could see the menu at animal control.
Let me clarify one thing, on large fires, a fire investigator is sent to the fire. Fire investigators mostly due a great and accurate job of finding the cause of the fire. The fire calls I am talking about are the ones that cause minim damage. These make up a vast majority of the NFPA fire reports. Most of these fires do not warrant a fire inspector be called. In small FD, a fire inspector may make every fire. My reference is to large FD departments in large cities. These departments have a few inspectors to cover a large area and only respond to larger fires. Dryer fires are very common due to years of lint build-up. Although this is an electrical appliance, the fire is not caused by electrical malfunction. But I have made fire calls on a dryer where the cause was caused by a dryer cord shorting against the chassis where it enters the dryer. This is electrical. The details you put in the fire report help the NFPA & NEMA develop codes and rules to address these problems.
