Question Bank
Section 1: Principles of Drying and Restoration (Questions 1–10)
Question 1
What is the most critical course of action in restorative drying?
A) Increase indoor humidity
B) Respond quickly
C) Use high-temperature drying
D) Limit air movement
Correct Answer: B) Respond quickly
Rationale: Rapid response minimizes water migration, secondary damage, and mold growth.
The ANSI/IICRC S500 emphasizes initiating mitigation within 24–48 hours to reduce damage.
Question 2
What are the four principles of water damage restoration?
A) Extract, ventilate, cool, monitor
B) Provide for safety, document, mitigate, dry
C) Clean, disinfect, dry, replace
D) Assess, remove, dry, humidify
Correct Answer: B) Provide for safety, document, mitigate, dry
Rationale: The S500 outlines safety, documentation, mitigation, and drying as core principles to
ensure effective restoration and compliance.
Question 3
What is the primary purpose of water extraction in restoration?
A) Increase evaporation
B) Contain water from spreading
C) Reduce humidity
D) Prevent structural damage
, 2
Correct Answer: B) Contain water from spreading
Rationale: Extraction removes excess water, preventing migration and reducing drying time.
The S500 highlights extraction as the first mitigation step.
Question 4
Which factor most influences the rate of evaporation in drying?
A) Humidity, airflow, temperature (HAAT)
B) Room size and shape
C) Type of flooring material
D) Outdoor weather conditions
Correct Answer: A) Humidity, airflow, temperature (HAAT)
Rationale: The HAAT model (humidity, airflow, temperature, time) drives evaporation by
managing environmental conditions.
Question 5
When is a drying project considered complete?
A) When visible water is removed
B) When material moisture content meets drying goals
C) After 48 hours of drying
D) When air movers are turned off
Correct Answer: B) When material moisture content meets drying goals
Rationale: Drying is complete when moisture content in materials returns to pre-loss levels or
dry standards, verified by moisture meters.
Question 6
What is the purpose of an open drying system?
A) Increase indoor humidity
B) Use outdoor air to reduce indoor humidity
C) Seal the structure completely
D) Use dehumidifiers exclusively
Correct Answer: B) Use outdoor air to reduce indoor humidity
Rationale: Open drying uses ventilation to exchange humid indoor air with drier outdoor air,
effective when outdoor humidity is lower.
Question 7
When is a closed drying system recommended?
A) When outdoor humidity is low
B) When outdoor humidity exceeds indoor humidity
C) When mold is present
D) When air movers are unavailable
Correct Answer: B) When outdoor humidity exceeds indoor humidity
