IICRC Water Restoration Technician Questions
With Correct Answers
Ground plug For safety with what should all are drying equipment be equipped?
Remove from service and replace the cords What should we do with equipment that has
damaged electrical cords?
Respond quickly What is the most critical course of action when we get a water damage loss?
To quickly contain moisture migration What is the purpose of the initial extraction?
Yes Can drywall be restored after it becomes wet?
Remove them What should we do with ceilings that are sagging and wet?
Yes Is vinyl wallpaper a vapor barrier?
Inter-air drying How can we increase the rate of evaporation from wet drywall with vinyl
wallpaper on it?
Remove it How should we address blown cellulosic insulation in wall cavities when it becomes
wet?
Less processing Why is plywood more restorable than particleboard?
Remove it If you have water trapped between plywood and sheet vinyl, what should you do?
, No Can we normally dry wet particleboard under sheet vinyl?
Evaporation and dehumidification Drying materials require us to control which two things...?
Small amounts of airflow and warm air Wet wood subflooring Under stone or tile drying strategy
requires...
Yes Can you use small amounts of airflow and warm air to dry concrete?
It increases What happens to the VP in a material when we heat it?
It increases When you increase vapor pressure by heating, what happens to material's potential
for evaporation...?
Condensation occurs, evaporation stops What happens if the material is cooler than the dewpoint
temperature?
Evaporation Will occur VP (vapor pressure) of material = high; VP of air = low. What will happen?
With the application of heat, ice turns to a liquid and (with more heat) liquid turns to a gas. The reversal
happens with the removal of heat Describe water phase changes
Vapor absorbing What does Hygroscopic mean?
Microbial (mold) and bending or folding Describe some examples of secondary damage
Hygroscopic materials The secondary damage happened in Hygroscopic or non-Hygroscopic
materials?
