SECTION 1: Water Damage Categories & Classes (12 Questions)
Q1: Which category of water damage originates from a clean water source that does
not pose substantial risk to humans?
A. Category 2
B. Category 3
C. Category 1
D. Category 4
Correct Answer: C
Rationale: Correct because Category 1 water originates from a clean water source
such as broken water supply lines, tub or sink overflows with no contaminants, or
melting ice/snow, and does not pose substantial risk from dermal, ingestion, or
inhalation exposure.
Q2: A water damage technician discovers water that contains significant
contamination and has the potential to cause discomfort or sickness if contacted or
consumed. Which category of water damage is this?
A. Category 1
,B. Category 2
C. Category 3
D. Category 4
Correct Answer: B
Rationale: Correct because Category 2 water contains significant contamination and
has the potential to cause discomfort or sickness if contacted or consumed by
humans, including sources such as dishwasher or washing machine overflow, toilet
overflows with urine but no feces, or sump pump failures.
Q3: Water damage resulting from a sewage backup containing fecal matter,
pathogens, and toxic substances is classified as:
A. Category 1
B. Category 2
C. Category 3
D. Category 4
Correct Answer: C
Rationale: Correct because Category 3 water is grossly contaminated and can
contain pathogenic, toxigenic, or other harmful agents, including sewage, flooding
from seawater, rising water from rivers or streams, and wind-driven rain from
hurricanes or tropical storms.
Q4: Which statement best describes the relationship between water category and
drying classification?
, A. Category determines the level of contamination, while class determines the
amount and evaporation potential of water
B. Category and class are interchangeable terms describing the same concept
C. Category determines the amount of water, while class determines the
contamination level
D. Category and class are only relevant for insurance billing purposes
Correct Answer: A
Rationale: Correct because water category describes the level of contamination of
the water source, while water class describes the amount of water present and the
rate of evaporation based on the percentage of wet porous materials affected.
Q5: A water damage restoration technician assesses a residential water loss where
water has only affected a small area of a concrete floor with minimal wet carpet and
cushion. Which class of water damage is this?
A. Class 1
B. Class 2
C. Class 3
D. Class 4
Correct Answer: A
Rationale: Correct because Class 1 water damage involves the least amount of
water, absorption, and evaporation, affecting only part of a room or area with
low-permeability materials such as concrete or plywood subfloor with minimal wet
carpet and cushion.
