I have an insurance company that refuses to pay for the use of an AFD on a water loss in the home of an elderly person who has breathing problems. I can’t seem to find anything in the latest edition of S500 that supports its use.
Do you have anything that might help me convince them that the AFD is reasonable and necessary?
We found a reference on AFDs and health. S500-15 Chapter 13, paragraph above the section entitled Controlling Humidity and Determining Initial Dehu Capacity. It says:
Airmoving devices inherently tend to aerosolize soils and particulates present in the environment. As water evaporates from surfaces and materials such as carpet, more particles often become aerosolized, creating possible health, safety, comfort and cleanliness issues. Restorers should perform a preliminary cleaning of materials and surfaces (e.g., carpet, hard surface floors, exposed subfloors) to reduce the amount of soil or particulates that can become aerosolized, before activating airmoving devices. Where preliminary cleaning cannot sufficiently remove soil or particulates, or there are high-risk occupants, restorers can install one or more air filtration devices (AFDs) as a negative air machine, or to control or direct airflow.
I’ve also attached an article on AFDs on Disaster Jobs. It covers both fire and water situations. Perhaps that will help.
