Cincinnati Fire Damage: Article About Thermal Fogging
Thermal fogging is one of the most effective ways to deal with smoke odor left behind after a fire. It is likely that a Cincinnati fire damage restoration professional will use thermal fogging as part of a restoration project. Thermal fogging works by creating a dry fog, reducing the particle size of the counteractant to that of smoke particles and driving the counteractant into hard to reach places, such as vents, cracks, crevices and porous surfaces. This application process makes the counteractant more effective at neutralizing smoke particles and preventing odors from recurring. It is more effective because it recreates the heat and pressure conditions similar to the actual fire.
A building must be properly prepared for thermal fogging before the process begins. Windows and doors should all be closed, and any closet doors, dresser drawers and cabinets should be opened. Any open flames should be extinguished, including pilot lights. A professional restorer will likely notify the fire department of the impending procedure, and it may also be a good idea to notify neighbors because the fogging often appears to be smoke. Smoke detectors should be disabled because the fogging will set them off.
Thermal fogging is performed in teams of two.

One member prepares the room and guides the person with the fogger. The process is planned so that the team can move slowly backward out of the room or area being fogged. Drawers, closets and cabinets are fogged first. The corner of the room farthest from the exit door is then fogged. The process moves slowly backward toward the exit door. The treated area is then left to rest for at least 30 to 60 minutes to allow the fog to fully penetrate into surfaces. Once treatment is complete, the area is opened and thoroughly ventilated to remove the chemicals and odors. Ventilation typically takes 30 minutes or longer depending on the size of the area and the efficiency of air flow.
Use of a thermal fogger remains one of the most effective ways of dealing with lingering odors caused by smoke damage. While it may be considered one of the more intensive restoration processes, it has proven to be highly effective. Only a professional restorer with the proper equipment should attempt thermal fogging. If thermal fogging is done improperly or without the proper equipment and safety gear, it may cause even more damage to a home's surfaces and furniture. The chemicals used in thermal fogging dissipate so long as there is venting, and they will not present a lingering hazard.
