| IICRC S500 Storm Damage Restoration Recommendations
The following information from the Institute of Inspection, Cleaning and Restoration Certification (IICRC) is a public service to those who have suffered water-related losses due to storm damage (e.g., hurricane, tornado).
Whether insured or not, it is important for property owners to document damage with photographs or video, and immediately, to begin loss mitigation procedures themselves; or hire a qualified contractor to do this on their behalf. It is totally inappropriate to put off mitigation while waiting for an insurance claims representative to arrive on the scene to evaluate the loss. By that time, in all probability sufficient time will have passed to grow and amplify microorganisms, which may not be covered by insurance. Loss mitigation is defined by insurance policies as “reasonable and prudent measures designed to preserve, protect and secure property from further damage,” including microbial growth and amplification.
According to the IICRC Standard and Reference Guide for Professional Water Damage Restoration (IICRC S500), there are three different categories of water that cause damage in buildings. The following is a summary of each of them.
Category 1 Water – That which is clean at the releasing source and does not pose a hazard if consumed by humans. Category 1 water could become progressively contaminated if it mixes with soils on or within floor coverings or building assemblies (walls, decking, and subflooring). Time and temperature, which promote the growth and amplification of microorganisms in water, can cause Category 1 water to degrade. Some examples of where this water could come from are: burst water pipes, failed supply lines on appliances, vertically falling rainwater.
Category 2 Water – That which begins with some degree of contamination and has the potential of causing sickness or discomfort if consumed by humans. As with Category 1 water, time and temperature could cause Category 2 water to become increasingly more contaminated.
Category 3 Water – That which is highly contaminated and could cause death or serious illness if consumed by humans. Some examples include: sewage, rising flood water from rivers and streams, ground surface water flowing horizontally into homes. There are two ways in which water enters a building as a result of wind storm damage: The first involves falling or windblown rainwater that enters as a result of damage to roof components or wall assemblies. The second involves horizontally traveling ground surface water (Category 3) containing silt and soil contaminants that infiltrate into structures, generally through doors or around foundation walls. This ground surface water (storm surge) may accumulate to a depth of several inches or several feet. When structures are partially submerged or remain substantially flooded for weeks, far more elaborate procedures usually are required. |
