IICRC WRT & ASD

IICRC WRT & ASD Wearing PPE on a sewage damaged project shall be done because it - Is mandotary due to natural law or regulatory requirement technicians Should clean and dry affected materials because it is - component of the accepted standard of care, but not mandatory. If something is recommended, that means it is - Advised or suggested but not a component of the standard of care May means - Signifies permission but not a component of the standard of care The word CAN means - The ability or possibility but not a component of the standard of care We need to leave buildings that have been damaged by water both - Clean and dry The first concern of restorers on a project is - The health and safety of workers and occupants why is rapid response so important - Limits the potential for damages and can reduce drying time Attempting to identify safety issues should begin as soon as - The inspection process you find sagging ceilings that are heavy and saturated with water what should you do? - Drain the water, remove the saturated drywall and dispose of it When water is evaporating and leaving a surface the surface - Cools Air movers primarily aid in drying by increasing - The rate of evaporation PPE is required by regulations so it shall be used according to the s500 - True Thermal imaging cameras help find water that is evaporating because the surface is - Cooler Other than extraction what has the most effect on drying time - The rate of evaporation what air temperature range is ideal for LGR dehumidifiers? - 70-90F This course is designed as a comprehensive safety course - False For safety, drying equipment shall be equipped with a - Grounded plug name 3 components of a respiratory protection program - Medical evaluation, fit testing, and proper training If you are cleaning up a sewer damaged project, at a minimum what PPE should be worn? - Full face respiratory, water resistant suit and waterproof gloves and boots This course is designed to teach you how to identify and handle hazardous material - False Name two hazardous materials that are more likely to be found in older building - Lead and asbestos What organization has safety and health courses specifically tailored to the restoration industry - IICRC According to the Hierarchy of controls what is the least effective control measure? - PPE What is an IEP - Indoor Environmental Professional What begins at 20% wood moister content or above? - Wood Root Fungi What can begin at 16% wood moister content? - Non-destructive mold growth Name 2 reasons why we should begin remediation as soon as possible. - Reduce potential for damage and reduce potential for microbial growth What antimicrobial provides the lowest level of microorganism reduction - Sanitizer When you find mold on a water damage project, what are 3 things you should do? - Put on appropriate PPE, initial barriers or containment and install ventilation If you find mold growth, what equipment would you not install? - Air movers what category of water is from a sanitary source and not likely to make you sick? - Cat 1 What category of water contains significant contamination and can make you sick? - Cat 2 When should a restorer consider bringing in an IEP on a Cat 2 or Cat 3 water intrusion? - Where there are high risk individuals or situations Products that will reduce microorganism to a level that public agencies would consider safe are called - Sanitizers Where do you look for directions as to how a biocide shall be applied? - The product label Prior to application of an antimicrobial, obtain authorization the insurance adjuster - False Uses pins for finding the perimeter of water under carpet and padding - Moister sensor Uses a picture to assist in finding the perimeter of water in carpet and pad - thermal imaging camera Measures temperature and humidity of air - Thermo hygrometer Determines how much moisture is in structural materials - Moister meter Can be used to determine initially if there is water under vinyl or ceramic tile floors - Pinless meter Provides a visual image of temperature and may show a surface is wet because it is cooler due to evaporating cooling - Infrared camera When evaporating occurs faster than dehumidification the humidity will increase. What kind of damage can be caused? - Secondary damage What type of materials are most likely to be damaged by high humidity? - Hygroscopic The change for microbial growth on hygroscopic materials increase when relative humidity is - 70% Wet, porous materials represent more than 40% of the combined wall, floor and ceiling surface - Class 3 Wet porous. Materials represent less than 5% of the combined wall, floor and ceiling surface - Class 1 Wet porous materials represent from 5 to 40% of the combined floor, wall and ceiling surface - Class 2
