The most important aspect to any job is: - Risk/Hazard assessment for the safety of all
individuals involved
Safety in water damage restoration includes: - Engineering controls, Immunizations from
a Primary care physician, and PPE
Employers must provide which of the following to any employee working in a repirator: -
Medical evaluation, Fit test, and training
Water damage mitigation services do not start until - A work authorization (contract) has
been signed
During the initial inspection when looking for areas impacted by water damage: - Check
all areas that could potentially be affected
Often found in older structres, lead and asbestos are hazardous materials regulated by the
Federal Government (true or False) - True
The Category of water refers to the range of contamination in water considering both its
originating source and its quality after contacting materials on the jobsite. (True or False) -
True
Water that has significant degree of contamination and could cause illiness is: - Category
2
Water that is grossly contaminated is: - Category 3
If stopped from removing highly porous materials (e.g. carpet) on a Category 3 job, what should
a restorer do? - Stop work to prevent liability
Water that contains diesel fuel is: - regulated, Hazardous Materials or Mold
The three types of damage a tchnician needs to identify, document, and communicate to
materially interested parties are: - Pre-existing, primary, and secondary
Secondary damage are more likely to occur when relative humidity levels are: - 55%
Performing a thorough extraction or multiple extractions.... - Reduces drying times
Water extracted from a jobsite should be... - Disposed of according to local laws
, In a basement that measures 25' x 30' and has water standing at a depth of 9", how many
gallons total are there? - 4,208 gallons 25 x 30 x (9/12 = 0.75) x 7.481
In a crawlspace that measures 12' x 15' and has water standing at a depth of 5'3", how many
total gallons of water is there? - 12 x 15 x (5'3" = 5 3/12 = 5.25) x 7.481= 7,069 gallons
A moisture reading obtained from an unaffected material that allows the restorer to set drying
goals for the affected structure is the___ - Dry standard
When is a drying job done? - A moisture meeter indicates we have met our dry goal
The moisture sensor can be used to verify our drying goal has been met (True or False) -
False
Moisture sensors and IR cameras are effective tools for: - quickly locating moisture in
carpet and pad and establishing a wet perimeter.
What does a thermo-hygrometer measure? - Temperature and relative humidity
When do (IR) infrared cameras indicate possible moisture in materials? - Materials
surface temperature cools as water evaporates. Moisture in materials can cause temperature
variations due to differences in thermal conductivity.
once an area is identified with an infrared camera as a suspect of being wet, that area must be
verified with: - A moisture meter or sensor
Psychrometric conditions have a direct effect on the rate at which moisture moves within
materials, as well as from wet materials. (True or false) - True
What are the three things restorers can manipulate to promote drying? (sometimes called the
drying pie) - Humidity, Airflow, and Temperature
The ratio of moisture in the air, as compared to the maximum amount the air could hold at that
temperature is... - Relative Humidity (RH)
What is the ratio of the weight of water vapor mixed with a specific weight of dry air called? -
Humidity Ratio
The ____ difference between the dew point temperature of surrounding air and the
temperature of the affected material (if warmer), the greater the potential for drying (smaller or
greater) - greater
To promote effective drying restorers need to control: - surface temperature of the wet
materials, air temperature of the drying chamber, and vapor pressure of the drying chamber
