Electric fires are becoming more common as appliances and electric feeds are used more and more in our daily lives. Like other fires, the root cause of an electric fire is the introduction of heat, oxygen, and fuel. In electrical fires, the heat is released as electricity is dissipated through a resistive element, while the fuel may come from the surroundings or from the material that makes up the appliance. When analyzing an electrical fire, it is important to find the origin of the fire as well as the safety precautions that could have prevented the fire. Some common causes of electrical fires and explosions include insufficient insulation and improper grounding.

Expertise

Questions Answered

We have experience in many aspects of electrical fires and explosions including:
  • Measuring and testing appliances and their components to trace the cause and origin of fire
  • A reference library including electrical standards and codes
  • Measuring operating parameters and comparing these to pre-fire values

Case Examples

Circuit Breaker Explosion:
A man was exposed to 4000 amps when he accidentally dropped his screwdriver into a live industrial electrical panel. When this happened, several metal parts in the circuit box vaporized causing an explosion. Initially, he was thought to have suffered an electric shock. Our investigation revealed that his injuries had all been caused by secondary explosions. He was not hurt directly by the electricity in any way. This information was needed to show that the wiring installation was not sufficiently grounded.

Schoolbus Crossing: Safety and Security Part 1

By: Ned Einstein

In the last installment (STN, Jun, 2007), I stressed the importance of distinguishing between an actual bus stop and the waiting area across the street from it in terms of safety. But the selection of the stop and waiting area also involves concerns for student security. Sometimes, there are trade-offs that must be made. These trade-off are often complex and subtle. But they must be made correctly.
