WATER RESTORATION IICRC FINAL PAPER
FULL ANSWERS VERIFIED 2026
⩥ open , closed or combination - how to decide. Answer: is the outside
air humidity ratio lower?
no : use closed drying
yes: is the outside air warmer than 70 F?
no: may use combination drying
yes: is the security, weather, customer preference
agreeable to open drying?
no: use closed drying
yes: can use open drying
⩥ if open drying is determined appropriate, the following options (while
keeping building security in mind) are available to the restorer. Answer:
- using ventilation
- open windows
-install fans to create pressure differentials & air exchange
⩥ ____ drying systems merge the benefit of both open and closed
drying: the use of available dry air from outside and the control offered
, by a closed system and mechanical dehumidification. Answer:
combination
⩥ Elevating the temperature of a material will increase the _____
________ associated with the moisture in the material.. Answer: vapor
pressure
⩥ if the surface temperature of the material is higher than the _____
temperature of the surrounding air , evaporation may occur.. Answer:
dew point
⩥ which of these surfaces temperature would have the fastest rate of
evaporation?
10 degree below dew point
20 degree above dew point
30 degree above dew point. Answer: 30
⩥ class 1 water intrusions involve the ____ amount of water absorption,
with less than __ % of the area surface being wet porous materials..
Answer: least , 5%
⩥ class 2 water intrusions involve a _____ amount of water absorption,
with more than ___ but less than ___ of are surface being wet porous
materials. Answer: significant
