IICRC WRT EXAM SCRIPT 2026 FULL
QUESTIONS AND ACCURATE ANSWERS
GRADED A+
●● 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
