WATER RESTORATION EXAM IICRC
QUESTIONS AND ANSWERS VERIFIED AND
1. The most critical course of action in restoration during is to an
begin as soon as possible: respond quickly & mitigation
2. All restorers should follow the standard of care for the water restoration pro-
fession developed by the restoration industry entitled the IICRC .: s500
3. to help protect technicians from the many hazards associated with conta-
minated water losses restorers need to have ready access to several items.
these items protect for all to the body.: potential exposures
4. respiratory protection regulations state that the employer must provide: 1.
medical evaluations
2. fit testing
3. training
5. the contract clearly states the agreement between the building owner and
the restoration contractor. the form specifies who is responsible for payment
and should be signed work begins: before
6. the technicians first responsibility when arriving at a water damage site is to
identify communicate and eliminate if reasonably possible: safety
hazards
7. federal regulations apply to handling or disturbing of
based paint and
asbestos: lead
8. After safety concerns have been addressed and the initial water source
has been stopped, the restorer must complete an evaluation of the water's
migration through the structure. During this process, the restorer inspects all
areas.: potentially affected
9. the ultimate goal is to find the edge of water migration which moves in a
three dimensional path throughout the structure. this is accomplished across
carpeted surfaces using a and across most hard surfaces using a
(non-penetrating) moisture meter.: moisture sensor , non-invasive
10. water from a clean source with no substantial risk of causing sickness or

  1. cleaning procedures must be employed before the drying of a category 2 water loss can continue. at a minimum affected must be removed and disposed of and carpet must be throughly cleaned using a hot water extraction method.: carpet underlay
  2. When water intrusion results from a grossly unsanitary source or carries (disease causing) agents, it is said to be Category 3.: pathogenic

4 / 11

  1. the primary goal of the initial extraction of the affected area is to contain further of the water within the structure.: migration
  2. Whenever carpet must be disengaged from the tackless strip, a and carpet awl must be used.: knee kicker
  3. the majority of cushion has a skin or mesh on the top side. the purpose of this skin is to ease during installation: it is not a vapor barrier: carpet stretching
  4. If carpet is to be re-installed, technicians should avoid cutting carpet seams unless it is absolutely: necessary
  5. how many gallons of water are presenting a basement that measures 30' x 25' where water is standing at a depth of 6'9": 30'x25'x6.75' (9"/12") = 5062. cuft x 7.48= 37,867.
  6. every cubic foot of standing water present in a structure contains gallons (28.3 liters) and each gallon (3.8 liters) of water wights 8.34pounds (3.8 kg): 7.
  7. there are 3 levels of biocidal activity, according to the environmental protection agency EPA( provide starting with weakest): 1. sanitizer: cleaning treatment designed to reduce # of pathogenic microorganisms to a safe level.
  8. disinfectant: designed to destroy or inactivate microorganisms but not necessarily their spores
  9. Sterilizer: a product designed to destroy or eliminate all forms of microorganisms (fungi, bacteria, viruses) and their spores.
  10. whenever a chemical antimicrobial or biocide is used restorers must follow the label explicitly: directions
  11. most antimicrobials require that the area of application be vacated by and pets during application and or a period of time after application.- : occupants
    • The label is the law" get customer briefing before starting any antimicro- bial / biocide treatment.:
  12. establishing is the best way to set restorative dying goals. A dry standard is established by obtaining a moisture reading using an material: dry standard , unaffected
  13. the numerical value from a moisture meter can be documented and used to monitor progress, for this reason, the amount of moisture absorbed by semiporus structural materials is measured most accurately with a moisture not a moister sensor.: meter
