WRT Certification questions and answers well illustrated. The most critical course of action in restorative drying is to _______ ______ and begin __________ as soon as possible. - correct answer. respond quickly & mitigation All restorers should follow the standard of care for the water restoration profession developed by the restoration industry entitled the IICRC ____. - correct answer. S500 To help protect technicians from the many hazards associated with contaminated water losses, restorers need to have ready access to several items. These items protect for all _________ _________ to the body. - correct answer. potential exposures Respiratory protection regulations state that the employer must provide: - correct answer. 1. Medical evaluations 2. Fit testing 3. Training 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. - correct answer. before The technicians first responsibility when arriving at a water damage site is to identify, communicate, and eliminate ______ _______ if reasonably possible. - correct answer. safety hazards Federal regulations apply to the handling of ____ based paint and asbestos. - correct answer. lead 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. - correct answer. potentially affected 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. - correct answer. moisture sensor & non-invasive Water from a clean source with no substantial risk of causing sickness of discomfort is said to be ________ _ water. - correct answer. Category 1 Water that has a significant degree of chemical, biological, and/or physical contamination and a potential to cause sickness or discomfort is ________ _. - correct answer. Category 2 Cleaning procedures must be employed before the drying of a Category 2 water loss can continue. At a minimum, affected ______ ________ (or pad) must be removed and disposed of, and carpet must be throughly cleaned using hot water extraction method. - correct answer. carpet underlay When water intrusion results from a grossly unsanitary source or carries __________ (disease causing) agents, it is said to be Category 3. - correct answer. pathogenic Workers and occupant ______ and safety are the first priority on every sewage loss. Areas affected by Category 3 water intrusion are marked and posted as potentially hazardous. - correct answer. health Various cleaning and decontamination procedures must be used on Category 3 water losses, including the removal of all ______ ______ materials affected by the water intrusion. - correct answer. highly porous When resistance is encountered and performing proper services in a Category 3 water loss becomes a challenge, restorers ____ ____ immediately to prevent liability and address the conflict. - correct answer. stop work Third party experts are commonly referred to as Indoor Environmental Professionals, or ____. - correct answer. IEPs Losses where regulated or hazardous materials have contaminated the structure do not change the _______ of water. - correct answer. category Pre-existing conditions should be identified, documented, and communicated to all __________ __________ parties during the initial inspection. - correct answer. materially interested When carpet delamination (the loss of integrity in the adhesives used to laminate the _______ and _________ backings) has occurred, further damage is very likely. For this reason, when extensive carpet delamintation is discovered, technicians must call it to the attention of all materially interested parties, document the condition and suggest ___________. - correct answer. primary, secondary, & replacement There are a number of causes for carpet delamination -- many of them related to ________ restoration activities. - correct answer. improper Typical causes of carpet delamination are: - correct answer. 1. Folding or stretching carpet when wet 2. Overly aggressive extraction 3. Improperly specified carpet underlay 4. Improper installation 5. Improper removal from tack strip 6. Improper floating of carpet 7. Excessive wear 8. Pet damage Many building materials will absorb excess water vapor and suffer damage, especially when air is allowed to remain above __% relative humidity. - correct answer. 60 Hygroscopic materials gain and lose moisture continually in an effort to ________ with the water content in the surrounding air mass. The more hygroscopic the material, the faster it will collect water vapor, and the easier it will suffer _________ damage. - correct answer. equalize & secondary When water intrusion results in water running through wall cavities, inspection access holes are used to ensure that blow-in insulation has not compacted and lost its _-_____. - correct answer. R-Value The most effective way to speed the drying process is to remove as much of the water in a liquid state as possible during the ___________ phase (for example, multiple extractions). Poor extraction will significantly slow the drying process. - correct answer. extraction Abide by local ____ and regulations when disposing extracted water. Waste water is best disposed of into a sanitary sewer. - correct answer. laws The primary goal of the initial extraction of the affected area is to contain further _________ of the water within the structure. - correct answer. migration Whenever carpet must be disengaged from the tackless strip, a ____ ______ and carpet awl must be used. - correct answer. knee kicker 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. - correct answer. carpet stretching If the carpet is to be re-installed, technicians should avoid cutting carpet seams unless it is absolutely _________. - correct answer. necessary Every cubic foot of standing water present in a structure contains _.__ gallons (28.3 liters), and each gallon (3.8 liters) of water weighs 8.34 pounds (3.8 kg). - correct answer. 7.48 There are 3 levels of biocidal activity, according to the Environmental Protection Agency (EPA): - correct answer. 1. Sanitizer (reduces pathogens to a safe level) 2. Disinfectant (destroys microorganisms, but not spores) 3. Sterilizer (destroys microorganisms, including their spores) Whenever a chemical antimicrobial or biocide is used, restorers must follow the label __________ explicitly. - correct answer. directions Most antimicrobials require that the area of application be vacated by _________ and pets during application and for a period fo time after application. - correct answer. occupants Establishing a ___ ________ is the best way to set restorative drying goals. A dry standard is established by obtaining a moisture reading using an __________ material. - correct answer. dry standard & unaffected The numerical value form a moisture meter can be documented and used to monitor progress. for this reason, the amount of moisture absorbed by semi-porous structural materials is measured most accurately with a moisture _____, not a moisture sensor. - correct answer. meter Because of their non-invasive nature and quick surveying capabilities, non-invasive meters are the most effective tools for locating abnormal moisture behind and beneath finishing materials such as _______ ____ and resilient _____ floor coverings. - correct answer. ceramic tile & vinyl A thermo-hygrometer is used to monitor any air that can influence the ___________ and/or ________ ________ with a restorative drying environment. - correct answer. temperature & relative humidity To evaluate the progress of structural drying projects, restorers should measure: 1. moisture in __________ being dried (moisture content readings) 2. ___ being used to dry affected materials (psychrometric readings)
