What Are the Hazards of Fire-Damaged Vehicles?

[SanEmiliano]

Hazards of fire-damaged vehicles: After exposure to high temperatures, the plastic insulation layers of various wiring harnesses will have aged, making them prone to short circuits. In minor cases, this may burn out fuses and electronic control components, while in severe cases, it can lead to spontaneous combustion. In metal heat treatment processes, there is a technique called "annealing." After annealing, the hardness of the metal decreases, making it easier for further processing. A vehicle that has been through a fire essentially undergoes an "annealing" process on its body frame, which reduces the frame's strength. Therefore, fire-damaged vehicles are similar to accident-damaged vehicles in this regard. After a vehicle has been through a fire, the visible damage to plastic components is not the main issue—these can simply be replaced. The real danger lies in the changes to the vehicle's structural strength. Once exposed to fire, the metal's microstructure alters, causing the energy-absorbing zones in collision areas to lose their functionality. In the event of an accident, safety can no longer be guaranteed.
