QUESTIONS AND CORRECT ANSWERS | GRADED A+ |
NEWEST VERSION | VERIFIED ANSWERS
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.
