Category ____ water contains significant contamination and has the
potential to cause discomfort or sickness if contacted or consumed by
humans.
2
Rationale Category 2 water, or “gray water,” may contain
microorganisms or chemicals that can cause illness with exposure.
In a Category 3 water intrusion with elevated risk situations, restorers
should consider using an ______________________________________
to assist in a remediation assessment.
Indoor Environmental Professional (IEP)
Rationale IEPs have specialized training to evaluate contamination,
perform testing, and guide remediation protocols.
When working contaminated environments technicians should erect
________________________, don appropriate __________, and install
______________________.
Containment, PPE, Air filtration device (AFD)
Rationale These controls prevent cross-contamination, protect workers,
and maintain safe air quality.
When working in a CAT 3 water loss the PPE should consist of:
All of it: full face respiratory mask, protective suit, waterproof gloves,
waterproof boots
Rationale Category 3 involves sewage or grossly contaminated water,
requiring full-body and respiratory protection.
,If at any time during the remediation of a cat 3 loss, any materially
interested party disagrees with how the remediation processes will be
performed, restorers should ____________ immediately until the
conflict is resolved.
STOP
Rationale Work must halt to avoid liability or improper procedures until
all parties agree on remediation methods.
Which property of a material more relates to water vapor passing
through or out of it?
Permeance
Rationale Permeance measures how easily vapor moves through
materials— critical for evaluating drying strategies.
In order to effectively dry wood subfloor beneath vinyl floor, restorers
should remove the ____________________
vinyl floor
Rationale Vinyl acts as a vapor barrier, preventing moisture from
escaping and hindering drying.
When cellulosic insulation gets wet it should be __________ removed
Rationale Wet cellulose retains water, supports mold growth, and loses
insulating capacity.
Gypsum board that is saturated and sagging should safely ___________
and _________.
Drained and removed
Rationale Sagging drywall loses integrity and may collapse; draining
prevents water weight damage before removal.
When inspecting a water damaged structure, techs should inspect all
___________________ areas potentially affected
, Rationale Water travels through hidden paths; inspecting all possibly
impacted areas ensures no moisture is missed.
Class ___ water losses contain the least amount of water absorption
and evaporation load where wet, porous materials represent less than
5% of the combined floor, wall and ceiling surface area in the space.
1
Rationale Class 1 losses are minimal and easiest to dry due to limited
moisture absorption.
Class ____ water losses contain a significant amount of water
absorption and evaporation load where wet, porous materials represent
5%-40% of the combined, floor, wall and ceiling surface area in the
space.
2
Rationale Class 2 indicates moderate water absorption, often requiring
additional drying equipment.
The greatest amount of water absorption and evaporation load where
wet, porous materials represent more than 40% of the combined wall,
floor, and ceiling surface areas and where low evaporation materials or
assemblies have absorbed minimal moisture is a Class__________
3
Rationale Class 3 losses involve extensive saturation and require
aggressive drying and dehumidification.
Water intrusion that involves a significant amount of water absorption
bound within low evaporation materials and may require longer drying
times is a class ____
4
Rationale Class 4 materials like plaster, hardwood, or concrete hold
moisture deeply, extending drying duration.
