Water that is grossly contaminated is: - ANSWERCategory 3
If stopped from removing highly porous materials (e.g. carpet) on a Category 3 job,
what should a restorer do? - ANSWERStop work to prevent liability
Water that contains diesel fuel is: - ANSWERregulated, Hazardous Materials or Mold

laws
In a basement that measures 25' x 30' and has water standing at a depth of 9", how
many gallons total are there? - ANSWER4,208 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? - ANSWER12 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___ - ANSWERDry standard
