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 s 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 Significant amount of water absorption into low evaporation materials or assemblies Class 4 While we definitely want to get started with inspecting and planing a new project what is our first priority? Safety of workers and occupants Which of the following is most important during the initial walkthrough?

Asking questions and listening What devices are used to find the perimeter of water under carpet and padding? IR camera and moister sensor What devices are used to find the. Perimeter of water in materials like drywall and paneling? IR Camera and non-penetrating moister meter What must be completed before starting work? A signed work contract When relative humidity exceeds 70%, conditions are ideal for what type of damage? Secondary damage When you are initially trying to find the perimeter of wet carpet and padding a pinless meter could be used. False During the inspection professional moister meters should be used to document what information? Psychrometric conditions and material moister content

It is important that restorers inspect all potentially affected areas they will leave wet areas behind True If mold growth id discovered install air movers to clean the air. False when Can a drying project be considered complete When material moister content meets drying goals when you find preexisting damage take pictures and tell all materially interested parties (MIPs) True One of the main reasons for doing extraction Contain the water from spreading there are no applicable regulations over wastewater so you can dump anywhere False How many gallons of water are in a cubic foot?

What are 2 tools used to disengage carpet? Awl and Knee kicker When should seams be cut inn carpet to remove padding? Only when necessary you can cause carpet to delaminate if you do not handle it carefully or by detaching it without the proper tools True The primary reasons for the skin on padding is To make carpet installation easier opening windows an effective way to reduce humidity initially is called Open drying closing windows and using dehumidifiers to reduce humidity is called Closed drying What. Is one important goal in water damage restoration? Mitigate the cost and scope of damages

when making a decision on removing materials we should cut out most materials if practically False Drywall is ideally cut straight at what height? Below top of the base 1', 2', 4' or higher if affected areas requires HEPA vacuums are a good tool for cleaning up dust after materials removal True Name 2 steps in minimizing particulate aerosolization Pre cleaning and filtering air what meter measures the number of particles in the air? Particle counter the rating for a HEPA filter is 99.97% at .3 microns what piece of equipment specifically filters the air? Air filtration device

HEPA stands for high efficiency particulate air True What should you do when the ground plug is broken off of a power plug? Take the unit out of service till repaired When you are determining how much electricity you need to run drying equipment what is more important amps or volts? Amps What percentage of the power on a circuit is available for continuous use? 80% Two ways rapid airflow assists drying Creates pressure and transfer energy There is a direct connection between air speed and air pressure True air speed is measured in FPM (feet per minute)

air pressure is measured in Inches of water pressure On a project with 50F air inside, what type of dehumidifier could work? Desiccant in order to use LGR dehumidification on a project that is 50F inside, supplemental heaters will be needed True Which of these two dehu types produces the lowest vapor pressure air conventional or LGR LGR which of these two dehu types produces the lowest vapor pressure air: Desiccant or LGR Desiccant outside a water damage project it is 30F which dehu would benefit the most From that air? Desiccant

LGR Dehus work best in what temperature range? 70-90F Reducing the humidity of the air is called dehumidification True Desiccants remove water from the air using silica True Refrigerant dehumidifiers remove water from the air through Condensation The only time you can consider open drying is when the GPP outside is higher than inside False when you open the windows to reduce the humidity inside the building it is called open drying True when you are considering open drying conditions you should consider both outside air humidity and air temperature True

If the GPP outside is higher than inside the only drying system that you can consider is Closed drying when you are calculating dehumidification you need to know Class of water, cubic footage, type of dehu if the dew point changes what 2 other humidity measurements change Humidity ratio and Vapor pressure what is the measurable force that vapor creates on the things around it? Vapor pressure what is the temperature at which air reaches 100% relative humidity and condensation can occur? Dew point What is the weight of water vapor in dry air called? humidity ratio (GPP) reducing the amount of water vapor in the air is called Dehumidification

If you heat the air up but do not add anymore humidity to it what will the relative humidity do Decrease If you cool the air down but do not change the amount of humidity what will the relative humidity do Increase Vapor pressure like all other pressures seek Equilibrium The amount of moister in a sample of air compared to the maximum amount that air could have in it is called relative humidity Vinyl wall covering affects drying process because it is a vapor retarder True Carpet can be easily damaged while it is wet. If it delaminates the most likely solution is Recommend removal and replacement Measures how easily vapor can pass through a material Permeance

Carpet seams should only be cut where necessary. what is one necessary reason for cutting seams in salvable carpet? to remove carpet padding If drywall ceilings are saturated and sagging immediately remove and dispose of affected ceiling material (true or false) True when drywall is saturated it gets very soft and it wont regain its strength when dry (true or false) False Which subfloor materials is damaged the least when gets wet Plywood To dry the subfloor underneath vinyl flooring remove the vinyl (true or false) True when particle board gets wet what should you do with it Remove and dispose of it

Wet concrete can be dried by applying heat energy (true or false) True drying a wet wall cavity by injecting air into it speeds Evaporation Water damage protects should be monitored at least Daily Affected materials can be considered dry when They meet predetermined drying goals At minimum written documentation should include two things: psychrometric conditions and material moisture content (true or false) True Wood rot fungi can grow on materials at or above _____% moisture content 20 The drying goal for hardwood floors is within ____ percentage points of unaffected 2-
