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
