IICRC S500 WATER MITIGATION
When drying carpet a tech must remeber - ANSWERS-it must be handled carefully
as the latex can lose up to 80-85 % strength
Overly aggressive extraction and improper padding - ANSWERS-can cause
delamination
The "skin" on top of padding - ANSWERS-is there for ease of installation
Removing baseboards and introducing increased airflow - ANSWERS-increases
evaporation
Monitoring a water loss - ANSWERS-should be at least every 24 hours
When Blown in organic insulation, rock wool, or cellulosic gets wet - ANSWERS-it
loses its R value and settles
When water comes from overhead - ANSWERS-ceilings should be drained and
removed quickly
What is the formula for calculating CF of a room - ANSWERS-W x L x H
, What is the formula for calculating the SF of a room - ANSWERS-W x L
Calculate how many gallons of water are in a room that measures 25' x 22' with
2'6" of water - ANSWERS-W x L x (total inches/12) = 1375 gallons
convert the following into decimals: 2'4"; 2'5", 2'6", 1'4", 4'2" - ANSWERS-28" / 12
= 2.3, 29/12 = 2.4, 30/12 = 2.5, 16/12 = 1.3; 50/12 = 4.2
Refrigerant dehu - ANSWERS-wet air drawn in, cooled to dew point, condensation
collected, remaining air released warm
Desiccant dehu - ANSWERS-wet air adsorbs by desiccant wheel, dry air heated
and pushed out, cycle repeats, ideal for cool temps, dense materials, provides
lowest vapor pressure
Conventonial dehus - ANSWERS-condensation created, 70-90 degrees, 70
degrees/70 RH, lowest humidity ratio 55 gpp
Low grain refrigerant - ANSWERS-condensation created, 70-90 degrees, lowest
humidity ration 34 gpp
Humidity Ratio - ANSWERS-the amount of water vapor a volume of air contains by
weight
