Iicrc Wrt Exam With 46 Questions & Answers 2024 ( A+
Graded 100% Verifid)
1. Moisture levels of ______% will support destructive wood (rot) decaying fungi to
grow on wood surfaces.: 20%
2. relative humidity: 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.
3. ACM: Asbestos Containing Material
4. Daily Humidity Record: Occurring at least every 12-24 hours the recording the
relative humidity and temperature to determine Grains Per Pound (GPP).
5. Areas not directly wet will experience humidity elevation. Therefore...:
Technicians must isolate affected areas from non affected areas to gain best control of
humidity.
6. Vapor Pressure will always: ...seek a level of equilibrium within a confined space.
7. How many grains are in a pound of air?: 7000
8. Humidity ratio/specific humidity: The amount of water in the air (by weight)
contained in the parcel of air.
9. What is the goal for day 2 drying?: To get the humidity under 70 to ensure
mitigation.
10. Dew point is also known as ___.: saturation temperature or condensation
11. The Dew Point: the temperature at which the air becomes saturated with water
vapor (100%RH) and condenses on the cooler surfaces.
12. Where does condensation moisture cause mold?: Mold growth can occur in cold
spots of homes and buildings where warm indoor air encounters cold outside air or
vice versa.
13. Fog: When the air meets the dew point temperature.
14. Dew: The temperature at which condensation overwhelms evaporation.
15. Why might condensation be bad?: 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.
16. Biofilm: Any organic substrate and bacteria that tends to encourage mold growth.
17. Why are Thermal Cameras Important?: Thermal cameras, along with other
sensors can detect the moisture perimeter of wet carpet and cushion.
18. vapor pressure: A gaseous force exerted by the water vapor on its environment.
19. When does evaporation occur?: when vapor pressure of the ambient air (air in the
room) is lower that the vapor pressure of the wet material.
