Fire Damage Equipment which has suffered thermal damage as evidenced by cosmetic aberrations in plastic components may not be restored. Besides heat, a fire generates combustion by-products. These by-products are locked into the soot, which condenses on all cool surfaces. Smoke exposure during the fire for a relatively short time does little damage, but the particulate deposited contains active corrosive components. These components, in the presence of humidity and oxygen, will corrode metal surfaces.
Irreversible damage can occur in the time period of a few days.
The ultimate objective of restoration is to remove the contaminants. All of the equipment cannot be cleaned simultaneously, so it is important that immediate steps be taken to arrest the corrosion process. Move to another area if necessary. If you cannot move the equipment, seal each piece off from outside elements, but beware of trapping moisture inside the chassis. Desiccants may be required.
