IICRC WRT 2024/ 2025 TEST QUESTIONS AND VERIFIED ANSWERS|
100% CORRECT| GRADE A (LATEST UPDATE)
Moisture levels of % will support destructive wood (rot) decaying fungi to grow
on wood surfaces. -
Answer-20%
relative humidity -
Answer-Is the ratio of the moisture suspended in air expressed as a percentage of total
moisture holding capaciry of that air at a given temperature.
ACM -
Answer-Asbestos Containing Material
Daily Humidity Record -
Answer-Occurring at least every 12-24 hours the recording the relative humidity and
temperature to determine Grains Per Pound (GPP).
Areas not directly wet will experience humidity elevation. Therefore... -
Answer-Technicians must isolate affected areas from non affected areas to gain best
control of humidity.
Vapor Pressure will always -
Answer-seek a level of equilibrium within a confined space.
How many grains are in a pound of air? -
Answer-7000
Humidity ratio/specific humidity -
Answer-The amount of water in the air (by weight) contained in the parcel of air.
What is the goal for day 2 drying? -
Answer-To get the humidity under 70 to ensure mitigation.
Dew point is also known as .-
Answer-saturation temperature or condensation
The Dew Point -
Answer-the temperature at which the air becomes saturated with water vapor (100%RH)
and condenses on the cooler surfaces.
Where does condensation moisture cause mold? -
Answer-Mold growth can occur in cold spots of homes and buildings where warm indoor
air encounters cold outside air or vice versa.
Fog -
Answer-When the air meets the dew point temperature.
, Dew -
Answer-The temperature at which condensation overwhelms evaporation.
Why might condensation be bad? -
Answer-Condensation with a bio film (an organic film like soap or glue) present allows
mold to grow in a variety of surfaces from plastic to glass.
