,A non-invasive (non-penetrating) _______ ___ tracks the migration of water below hard finish
surfaces, such as under vinyl tile or ceramic tile ✔Correct Answer-Moisture meter
A invasive/ penetrating device to check moisture on carpet and padding. ✔Correct Answer-
_____ air holds MORE moisture than cold air. Air is dryer in winter. ✔Correct Answer-Warm
As the air gets warmer, RELATIVE HUMIDITY is _______.
100% RH in cold climate is DRYER than 50% RH in a warmer climate. ✔Correct Answer-Lowered
____ is the amount of moisture in the air compared to what the air can hold at that temperature.
RH is the amount of water vapor (individual water molecules) in a given parcel of air RELATIVE to the
# of water molecules that could be in that particular parcel of air.. without it reaching dew point (
Air is 78% nitrogen molecules, oxygen and others. Molecules aren't interacting w/ eachother. Space
between them. We can put WATER MOLECULES in that space.
RH = how many water molecules we are putting in the spaces between the air molecules.
As air is heated --> molecules move faster --> spread further apart ---> VOLUME INCREASES. More
space for more water molecules. ✔Correct Answer-Relative Humidity (RH)
water that originates from a sanatary water source and does not pose substantial risk.
Examples broken water lines, tub or sink overflows with no contaminants, appliance malfunctions
involving water supply lines, rainwater ✔Correct Answer-Category 1 Water
1st indicator that it went from category 1 to 2 --> ___ ✔Correct Answer-odor
Water that has a significant degree of chemical, biological and/or physical containment.
Aquarium leaks, waterbed leaks, toilet bowl overflows (that contain urine), dishwasher or clothes
washer discharge, and water that enters the structure from hydrostatic pressure.
Has the potential to cause sickness or discomfort and should NOT be allowed to dwell in a structure
for an extended period of time. ✔Correct Answer-Category 2 Water
Water that contains grossly contaminated water and can cause harmful reactions to humans. Carries
PATHOGENIC AGENTS
examples sewage, all forms of flooding seawater, water from river, etc. ✔Correct Answer-Category
3 Water
✔Correct Answer-Special Situations
Originates from a sanitary water source. ✔Correct Answer-Category 1
Contaminated; may cause discomfort or sickness. ✔Correct Answer-Category 2
, Grossly contaminated; includes toxins, pathogens. ✔Correct Answer-Category 3
Least amount of water, absorption and evaporation load (less than 5% porous materials wet
compared to SF of wet walls, floors and ceilings). ✔Correct Answer-Class 1
Large amount of water, absorption and evaporation load (5%-40% porous materials wet compared to
SF of wet walls, floors and ceilings). ✔Correct Answer-Class 2
Greatest amount of water, absorption and evaporation load (over 40% porous materials wet
compared to SF of wet walls, floors and ceilings). ✔Correct Answer-Class 3
Specialty drying - (hardwood; plaster; concrete) - deep pockets of saturation. ✔Correct Answer-
