DEFINITIONS Flashcards
Affected Area
The area of the structure impacted by secondary or primary damage.
Category 1
(Preciously known as clean) originated from a sanitary water source.
Category 2
(Previously known as grey) contaminated; potentially causes discomfort or sickness.
Category 3
(Preciously known as black) Grossly contaminated; included toxins and pathogens
Class 1
Wet less than ~5% of combined floor, wall, and ceiling surface area - mimimal moisture absorption by the materials
Class 2
Wet between ~5%-~40% of combined floor, wall, and ceiling surface area. Minimal absorption into the materials.
Class 3
Wet more than ~40% of combined floor, wall, and ceiling surface area. Minimal absorption into materials
Class 4
Deeply Held/bound water (hardwood; lath and plaster; concrete) water hidden, trapped, or bound in low evaporation assemblies. Requires controlled drying and low vapor pressure

Light Wand
Perimeter of water loss; extract glue-down carpets; follow-up extraction stationary tool
Stationary Tool
Subsurface tool; extract carpet and cushion together
Self-propelled tools
Self-propelled riding tool; multi-speed; extract carpet and cushion.
Vacuum squeegee
Concrete; hardwood; vinyl; laminate
Submersion pumps
Formula: (ft² x depth”) ÷ 12” =ft³ h2o x 7.48
Equals water volume
