WRT Study Guide
What is the S500? - answer Standard and Reference guide for professional water
damage restoration.
-Developed by the institution of inspection, cleaning, and restoration certification
(IICRC)
What is an SDS? - answer Safety Data Sheet
-identifies characteristics of chemicals including what to do if they are ingested, make
contact with eyes, skin, etc..
· The SDS shall be kept within reaching distance of the vehicles driver, while wearing
vehicle seatbelt at all times
What is a work authorization? - answer Contract between the contractor and the home
or business owner or the other party responsible for payment.
What is an Antimicrobial (Biocide) Authorizatioon? - answerGives consent to use an
antimicrobial within the structure.
-It should be signed by all materially interested parties.
-The contractor should also provide an SDS for products being applied.
What is the first priority on each project? - answerWorker and occupant health and
safety.
What are of the most common safety concerns at the work site? - answerSlip and fall
hazards
What does PPE stand for and what are some exampes? - answerPersonal Protective
Equipment
-Respirator
-Splash goggles
-Water resistant gloves
-Hard hat
-Rubber boots with steel toes
-Protective clothing
How is water damage CATEGORIZED? - answerBy level of contamination based on the
source and the surfaces contacted.
-Categories 1-3
Explain category 1 water damage - answerOriginates from a sanitary source & does
NOT pose significant risk of sickness.
EX: dishwasher supply line
, Explain category 2 water damage - answerSignificant contamination, includes risk of
sickness or discomfort.
EX: overflow from washing machine or dishwasher- has detergents and soils from
clothes or dishes
Explain category 3 water damage - answerGrossly contaminated, may require vacancy
of individuals with compromised immune systems.
EX: sewage overflow of waste line beyond the trap, flood from river overflow, hurricane,
etc.
What are some examples of regulated, hazardous materials or mold? - answerLead,
asbestos, mercury, etc.
How is the CLASS of water damage determined? - answerBy potential rate of
evaporation based on amount of water and types of materials affected.
-Classes 1-4
Explain Class 1 water damage - answer-Least amount of water absorption &
evaporation load.
-Wet, porous materials represent LESS than 5% of combined floor, wall, and ceiling
surface area in the space.
Explain class 2 water damage - answer-Significant amount of water absorption and
evaporation load.
-Wet, porous materials represent BETWEEN 5-40% of combined floor, wall, and ceiling
surface area in the space.
Explain class 3 water damage - answer-Greatest amount of water absorption and
evaporation load.
-Wet, porous materials represent GREATER than 40% of combined floor, wall, and
ceiling surface area in the space.
Explain class 4 water damage - answer-Deeply held or bound water
-Water intrusion that involves a significant amount of water absorption into low
evaporation materials.
-Drying may require special methods, longer drying times, or substantial water vapor
pressure differentials.
What are the extraction tools? - answer-Light wand
-Deep extraction (stationary tool- water claw or weighted compression tool)
-Squeegee
-Portable extractor
-Truck mount extractor
-Submersible pumps
