IICRC WRT EXAM
Moisture levels of ______% will support destructive wood (rot) decaying fungi to
grow on wood surfaces.
20%
Relative humidity
Is the ratio of the moisture suspended in air expressed as a percentage of total
moisture holding capacity of that air at a given temperature.
ACM
Asbestos Containing Material
Daily Humidity Record
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...
Technicians must isolate affected areas from non affected areas to gain best control
of humidity.
, Vapor Pressure will always
seek a level of equilibrium within a confined space.
How many grains are in a pound of air?
7000
Humidity ratio/specific humidity
The amount of water in the air (by weight) contained in the parcel of air.
What is the goal for day 2 drying?
To get the humidity under 70 to ensure mitigation.
Dew point is also known as ___.
saturation temperature or condensation
