Categories of Water Damages


These categories designate the TYPE of water that is involved in the loss!!!

Category 1:
Often referred to as “clean” water
A “clean” water source is one that does not pose substantial harm to humans.  Examples of clean water sources may 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 falling rainwater – not that which flows over the soil or through multiple structural components- broken toilet tanks, and even toilet bowls that do not contain contaminants or additives.  Once a clean water source contacts other surfaces and materials, its condition may change as it dissolves or mixes with soils and other contaminants, and as time elapses.

Category 2:  
Often referred to as “gray” water
Unsanitary or “gray” water contains some degree of contamination.  Potentially, it could cause substantial discomfort or sickness if consumed by humans, and it carries microorganisms or nutrients for microorganisms.  Category 2 (gray) water examples may include, but are not limited to: discharge from dishwashers or washing machines, overflows from washing machines, overflows of toilet bowls with some urine (no feces), broken aquariums, and punctured water beds.  All of these may contain chemicals or biopollutants (fungal, bacterial, viral, algae), or other forms of contamination.  Time and temperature aggravate Category 2 (gray) water contamination significantly.  Water in flooded structures that remains untreated longer than 48 hours can change from Category 2 (gray) to Category 3 (black).

Category 3: 
Often referred to as “black” water
Category 3  “black” water always contains pathogenic agents.  Grossly unsanitary, “black” water sources are those that arise from sewage or other contaminated water entering a structure.  Sewage contains the expected urine and feces; but it could also contain dangerous chemicals or medical wastes.  Toilet backflows that originate from beyond the toilet trap are considered to be Category 3 (black) water situations, regardless of visible content or color.  This category includes all forms of sea water, ground surface water, and rising water from, rivers or streams.  They carry silt and organic matter into structures and create Category 3 ”black” water situations.  In situations where structural materials and / or contents have been heavily contaminated with such materials as pesticides, heavy metals, or toxic organic substances; the water damage is considered to be Category 3 (black) water. 

The categories Of Water Damages inform you of the precautions that must be taken BEFORE you place airflow on the drying job.

Classes of Water Damages
These Classes are determined by the amount of water remaining in the structure after the physical extraction!!!!

Class 1:
Slow Rate of Evaporation- (Least amount of Water – Air Movers placed 16LF Apart)
Water losses that could affect only part of a room or area: or even large losses containing low permeance/ porosity materials (e.g., plywood, particle board, structural wood, VCT, concrete.)  Little or no wet carpet and / or cushion is present.  Minimum amount of moisture can be held in the remaining structural materials.

Class 2:
Fast Rate if Evaporation- (More water than Class 1 – Air Movers placed 14LF Apart)
Water losses that affect the entire room of “Carpet and Cushion” or several rooms of a large structure with “Carpet and Pad”.  Water has wicked up the walls as much as 24 inches.  There is moisture remaining in structural materials (E.G., plywood, particle board, structural wood, VCT, concrete.)  Due to the amount of water held in dirt or mud, crawlspaces, in most circumstances, will also fit under a class 2.

Class 3:
Fastest Rate of Evaporation – (Most Amount of Water – Air Movers placed 12LF Apart)
Water may have come from overhead.  Everything is wet.  Must have carpet and pad.  Ceilings, walls, insulation, carpet, cushion, and sub floor in virtually the entire area are saturated.  Will not run into this much at all.

Class 4:
Specialty Drying Situations-  (Specialty Drying Situations – Air Movers placed 16LF apart)
These losses involve wet materials with very low permeance/porosity (E.G., hardwoods, sub floor, plaster, brick, concrete, stone). Class 4 differs from a Class 1 due to the deep pockets of saturation that require the use of a desiccant or low grain dehumidifier to achieve very low specific humidity and time.  Even then, the Class 4 drying job will take more time – longer to dry – than a typical Class1
