Categories of Water Damage

What are the categories of water damage?

Categories of Water Damage: the categories of water, as defined by the, IICRC S500 document , refer to the range of contamination in water, considering both its originating source and quality after it contacts materials present on the job site.

Category 1: Category 1 water originates from a sanitary water source and does not pose substantial risk from dermal, ingestion, or inhalation exposure. Examples of Category 1 water sources can include, but are not limited to: broken water supply lines; tub or sink overflows with no contaminants; appliance malfunctions involving water-supply lines; melting ice or snow; falling rain water; broken toilet tanks; and toilet bowls that do not contain contaminants or additives.category 1 water damage

Category 2: Category 2 water contains significant contaminations and has the potential to cause discomfort or sickness if contacted or consumed by humans. Category 2 water can contain potentially unsafe levels of microorganisms or nutrients for microorganisms, as well as other organic or inorganic matter (chemical or biological). Examples of category 2 water can include, but are not limited to: discharge from dishwashers or washing machines; overflows from washing machines; overflows from toilet bowls on the room side of the trap with some urine but not feces; seepage due to hydro static pressure; broken aquariums and punctured water beds.category 2 water damage

Note: Seepage due to hydrostatic pressure is most often pertaining to sump pump backups.

Category 3: Category 3 water is grossly contaminated and can contain pathogenic, toxigenic or other harmful agents and can cause significant adverse reactions to humans if contacted or consumed. Examples of Category 3 water can include, but are not limited to: sewage; wasteline backflows that originate from beyond any trap regardless of visible content or color; all forms of flooding from seawater; rising water from rivers or streams; and other contaminated water entering or affecting the indoor environment, such as wind-driven rain from hurricanes, tropical storms, or other weather-related events. Category 3 water can carry trace levels of regulated or hazardous materials (e.g. pesticides, or toxic organic substances).

The category of water damage determines how a water damage contractor will complete the mitigation process.  Each category of water requires a different procedure for cleaning-up and drying the home or business.  If you are experiencing water damage and need immediate assistance give us a call.
