CPR Water Loss Classification & Category Standards 2

Question 1

In the IICRC water damage classification system, the 'class' of a water loss primarily refers to:

Accepted Answer

The rate of evaporation and the amount of water absorbed into materials

Answer

The level of biological contamination present

Answer

The total square footage of the affected area

Answer

The source and potability of the water

Question 2

A Class 1 water loss is characterized by:

Accepted Answer

Minimum absorption with water affecting only part of a room or low-porosity materials

Answer

Absorption of water into walls, ceilings, and structural materials throughout the room

Answer

Wet materials with slow evaporation and specialty drying required

Answer

Saturation of highly porous materials requiring aggressive drying

Question 3

Which class of water damage involves water that has saturated the entire room, including walls, floors, and ceilings, requiring the most equipment and drying time?

Accepted Answer

Class 3

Answer

Class 1

Answer

Class 2

Answer

Class 4

Question 4

Class 4 water losses differ from Classes 1–3 because they involve:

Accepted Answer

Materials with very low permeance or porosity requiring specialty drying techniques

Answer

Higher water volume only

Answer

Primarily Category 3 contaminated water

Answer

Structural collapse requiring rebuilding rather than drying

Question 5

Which of the following materials would most likely be associated with a Class 4 water loss?

Accepted Answer

Concrete slab and hardwood flooring

Answer

Carpet pad and drywall

Answer

Fiberglass insulation and vinyl tile

Answer

Ceiling tiles and acoustic panels

Question 6

A Class 2 water loss is best described as involving:

Accepted Answer

An entire room affected with water absorption into walls up to 24 inches

Answer

A small area with minimal absorption into low-porosity materials

Answer

Wet porous materials with a high rate of evaporation throughout the structure

Answer

Materials with very slow evaporation rates requiring specialty drying

Question 7

When setting up drying equipment for a water loss, a restorer uses the class of the loss to:

Accepted Answer

Determine dehumidifier and air mover placement and quantity needed

Answer

Determine the level of PPE required on site

Answer

Classify the type of contamination present

Answer

Estimate the insurance replacement cost
