2) Document & Inspect
3) Mitigate Further Damage
4) Clean and Dry Affected Areas
5) Complete Restoration and Repairs . Answer. Principles of Drying

________. . Answer. Safety hazards
>First line of defense against safety hazards is _______. 2nd is to identify the presence of regulated
building materials (asbestos, lead, PCBs) . Answer. Safety Awareness
>Elimination
Substitution
Engineering Controls
Administrative Controls
PPE (LEAST EFFECTIVE) . Answer. Hierarchy of Controls

>materially interested parties . Answer. MIP
>A non-invasive (non-penetrating) _______ ___ tracks the migration of water below hard finish surfaces,
such as under vinyl tile or ceramic tile . Answer. Moisture meter
, >A invasive/ penetrating device to check moisture on carpet and padding. . Answer.
>_____ air holds MORE moisture than cold air. Air is dryer in winter. . Answer. Warm
>As the air gets warmer, RELATIVE HUMIDITY is _______.
100% RH in cold climate is DRYER than 50% RH in a warmer climate. . 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. . 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 . Answer. Category 1 Water
>1st indicator that it went from category 1 to 2 --> ___ . Answer. odor
>Water that has a significant degree of chemical, biological and/or physical containment.
