AMERICAN CATASTROPHE EMERGENCY SERVICES CERTIFICATION PROGRAM 3 Created on March 05, 2022 By Andy Boarding Up Windows, Doors and Barricades and Traping Holes Am-Cats Ems certification program is designed to provide the correct techniques in securing openings cause by natural forces, unexpected catastrophes and or break-ins. 1 / 10 Q. What is the meaning of board up? A. DEFINITION; To open window or door with force. DEFINITION. To cover a window or door with wooden boards. All openings including windows and doors need to be boarded up, to close or lock secure all openings. DEFINITION. To cover window or door with, whatever is available to cover the windows lock secure door. DEFINITION. To cover doors, only the doors get boarded up, to close or lock secure the door. 2 / 10 Q. Should I Nail or Screw OSB sheets? A. Nails are often preferred for structural joining, including framing walls, because they are more flexible under pressure, whereas screws can snap. Nails are also called upon when securing plywood sheathing for exterior walls, installing hardwood floors, and attaching siding and roofing. B. OSB is pretty much a sponge when it comes to moisture. While the drywall screws will be fine, you're going to find 1 1/4" are not going to have a real good hold. C. When deciding between nails and screws, keep in mind that nails are less brittle, so they provide greater shear strength. Screws, on the other hand, may not be as forgiving, but their threaded shafts hold better in wood and draw boards together much more tightly and they have greater tensile strength. D. When you drive screws into wood without drilling pilot holes, you're essentially pushing wood out of the way to make room for the screw. That displaced wood puts more pressure on the wood surrounding the screw, which can lead to splitting and cracking, weakening the wood over time. 3 / 10 Q. What is a wooden barricade? A. A defensive, deployable object used to block your base from looters and break ins B. When used as a subfloor, either product will work for many flooring surfaces, especially carpet where there will be no noticeable difference. C. OSB roof panels should always be installed with the grade stamp facing into the attic and the screened surface (with the nail guide lines) facing up. D. To Barricade a Door, use a rope, power cord, or belt to tie the doorknob to a nearby heavy object, tape a broom handle perpendicular to the door frame, tying the handle to the doorknob to hold the door shut, if applicable, secure a belt around the top of the door hinge. 4 / 10 Q. Can you use 2x3 instead of 2x4 when boarding up? A. There is a BIG difference between 2x3 and 2x4, and I would never use 2x3 for wall framing. I ended up using 2x3's for the roof trusses to save weight, and still spaced them every 2 feet. B. Yes, 2x3 are preferred, because they can fit perfect in the window ledge in securing your boards. C. No, 2x4 will not fit in some window frames and doorways so you must cut them to fit. D. 2x3 are only used to build a doghouse. 5 / 10 Q. Are flat roofs high maintenance? A. Avoid Power-Washing Shingles, concentrated spray can loosen the granules from the products' top coating—and resulting damage might not be covered by the warranty, check the ventilation, clean gutters regularly, insulate attics and cathedral ceilings properly, fortify the roof. B. The biggest disadvantage of a flat roof is the lack of drainage, and this is why it is important to check your roof regularly. If you do not inspect it regularly, your drains may become clogged with snow and water. C. Water pools on flat roof will eventually cause leaks. That's when flat roof repair becomes necessary. While flat roofs are a little more prone to leaks, they don't always develop them. D. Depending on the quality of the original installation and continued maintenance, flat roofs can in actual fact easily last for up to 50 years at a time before needing to be replaced. This lifespan is almost as long as a tiled roofs, which themselves can last for up to 60 years. 6 / 10 Q. How do you secure a tarp down on a flat roof? A. Use OSB panels rated for the distance between the floor joists. Run a bead of construction adhesive along each joist and lay the OSB panel on the joists. Nail the panels with 10d common nails or #10, 2 1/2-inch wood screws spaced 6 inches apart along the edges and 12 inches apart in the middle. B. Nails are less brittle than screws, which leads to an increase in shear strength for nails. ... The sheathing panels brace the framing to stop the wall from toppling over and increasing the number of fasteners increases the wall's shear resistance. C. OSB roof panels should always be installed with the grade stamp facing into the attic and the screened surface (with the nail guide lines) facing up. D. Attach 2 x 4 boards to both edges of the tarp, just on the peak side perpendicular to the anchor board. This will hold the tarp tight to the roof and keep the water out. Extend the top edge of the tarp over the roof. If needed, cut off the excess tarp from the other end, leaving about a 4' overhang. 7 / 10 Q. Do flat roofs always leak? A. No, flat roofs are the best roofs. B. Flat roof, keep unwanted animals, like squirrels and birds, from nesting or foraging in your home. C. Sometimes water pools on the roof, and this will eventually cause leaks. That's when flat roof repair becomes necessary. While flat roofs are a little more prone to leaks, they don't always develop them or develop them about as often as other roof types. D. Tarping your flat roof is a standard practice. 8 / 10 Q. Why are roof tarps blue? A. Black, Gray, Dark Blue) Some of our heaviest and strongest materials (Hypalon, Neoprene, Vinyl) come in black and or darker colors. Often treated with UV Ray coatings to protect from the Suns Damage light. These darker tarps also absorb heat allowing covered items to remain cool. B. The closer to black a color gets, the lighter and heat it will absorb. The closer to white, the less it absorbs. So, a dark blue blanket, for instance, would absorb more heat than a neon green one. And something reflective will bounce most of that light off it. C. The blue tarp was invented in 1894 by Liverpool baker and Presbyterian Joseph Cunningham who wanted to provide young working men from Toxteth with an affordable holiday. D. Blue tarps are easily the most popular form of tarp and the most easily found, these colored tarps typically reflect sunlight rather than absorbing it. White is the best color tarp to reflect heat. Black and dark gray tarps absorb sunlight, rather than reflect it. 9 / 10 Q. What size thickness of wood is used for boarding up windows doors and store fronts? A. The recommended thickness of plywood, used, is 1/4 of an inch. When it comes to the plywood's size, start by measuring the size for boarding up windows. Then, when it's time to cut the plywood, make it so that it's 4 inches bigger than the window on all sides. B. The recommended thickness of plywood, used, is 1/2 of an inch. When it comes to the plywood's size, start by measuring the size for boarding up windows. Then, when it's time to cut the plywood, make it so that it's 4 inches bigger than the window on all sides. C. The recommended thickness of plywood, used, is 5/8 of an inch. When it comes to the plywood's size, start by measuring the size for boarding up windows. Then, when it's time to cut the plywood, make it so that it's 4 inches bigger than the window on all sides. D. The recommended thickness of plywood, used, is 3/4 of an inch. When it comes to the plywood's size, start by measuring the size for boarding up windows. Then, when it's time to cut the plywood, make it so that it's 4 inches bigger than the window on all sides. 10 / 10 Q. Should I use 2x4 or 2x3 for board ups? A. 2x3s for all exterior walls (or walls with one side you know you'll never need to finish). And 2x4s for all interior walls or walls with doors that need to be finished on both sides. B. 2x3s for all interior walls (or walls with one side you know you'll never need to finish). And 2x4s for all exterior walls or walls with doors that need to be finished on both sides. C. 2x4s for all interior walls (or walls with one side you know you'll never need to finish). And 2x4s for all exterior walls or walls with doors that need to be finished on both sides. D. 2x3s for all interior walls (or walls with one side you know you'll never need to finish).

What is considered as good lighting? A. Permanent lighting, temporary lighting is installed on a job site for a limited amount of time. These sockets connect to bulbs using leads that are linked to an electrical connection or generator to establish permanent illumination. B. One way to make fluorescent light look better is to use colored film to cover lights, changing the spectrum that reaches your eyes. C. Good lighting should be flexible enough to light a given area, while other areas remain in relative darkness. This has more to do with the number and placement of fixtures than wattage or number of bulbs. D. General construction areas require a minimum of 5 foot-candles of illumination. Plants and shops require at least 10 foot-candles. For other types of workplaces, the minimum illumination standards are as follows: First-aid stations and infirmaries: 30 f-c. Warehouses, walkways, and exits: 10 ft-c. 2 / 8 Q. Why is lighting needed? A. Why is lighting important? Whether in industrial or office settings, proper lighting makes all work tasks Harder. Appropriate lighting can increase workplace incidents by increasing the visibility of moving machinery and other safety hazards. B. Whether in industrial or office settings, proper lighting makes all work tasks easier. Appropriate lighting can prevent workplace incidents by increasing the visibility of moving machinery and other safety hazards. C. Appropriate lighting can increase workplace incidents by increasing the visibility of moving machinery and other safety hazards. D. Appropriate lighting can prevent workplace incidents by adding motion sensors throughout the unit to increasing the visibility of moving machinery only when the equipment is turn on. 3 / 8 Q. What are OSHA requirements for lighting? A. General construction areas require a minimum of 5 foot-candles of illumination. Plants and shops require at least 10 foot-candles. For other types of workplaces, the minimum illumination standards are as follows: First-aid stations and infirmaries: 30 f-c. Warehouses, walkways, and exits: 10 ft-c. B. Move workstations away from areas that are exposed to the sun or frequently become hot. C. As such, it seems that the highest possible known temperature is 142 nonillion kelvins (1032 K.). This is the highest temperature that we know of according to the standard model of particle physics, which is the physics that underlies and governs our universe. D. There is no legal maximum working temperature per say. OSHA recommends that employers set the thermostat between 68 and 78 degrees. Also, OSHA regulations come into play when temperatures reach an extreme level to the point where dangerous conditions like heat stress or hypothermia can occur. 4 / 8 Q. What is adequate light? A. Adequate lighting means levels of illumination suitable for tasks that the resident chooses proper lighting for the facility staff to be able to perform in. B. Adequate lighting means levels of illumination high beams for tasks that the resident chooses high level lighting for the facility staff to be able to perform in. C. Adequate lighting means levels of illumination very low for tasks that the resident can’t really see for the facility staff to be able to perform in. D. Adequate lighting means levels of illumination when only movement activates a motion sensor for tasks that the resident chooses proper lighting for the facility staff to be able to perform in. 5 / 8 Q. How do you calculate lighting requirements? A. One lux is equal to one lumen per square meter (lux = lumens/m2). Essentially, as light travels from the emitter, it will disperse throughout an area. The further the light must travel the more it will be dispersed. B. Raise the level of light for reading to 500–800 lux and concentrate task lighting on your needed surface at 800 to 1,700 lux. For example, in an adult's bedroom, you need lighting to be lower to wind down your body for sleep. C. Multiply width of room x length of room x 1.5 = amount of total minimum wattage needed (assuming an eight-foot ceiling). Divide by 60 to get the number of 60-watt equivalent bulbs required. Then, add up the wattage in each bulb in each fixture to figure out how many light fixtures are needed. D. For monochromatic light of this wavelength, the amount of illuminance for a given amount of irradiance is maximum: 683.002 lux per 1 W/m2; the irradiance needed to make 1 lux at this wavelength is about 1.464 mW/m2. Other wavelengths of visible light produce fewer lux per watt-per-meter-squared. 6 / 8 Q. Does OSHA require covers for fluorescent lights? A. OSHA officials can order work to stop if they find a severe risk on-site, but contrary to popular belief, they don't have the authority to shut down a business entirely. Only a court order can do that. B. Protective coverings for all light fixtures, whether they contain fluorescent bulbs or not. They must have protective plates. In areas where light fixtures could be damaged, they must be guarded by sufficiently strong barriers to prevent shattering. C. If OSHA determines that the incident was caused by the owner's or employer's negligence or misconduct—that is, he or she was aware of the hazard but did not abate it—the agency can impose fines as high as $70,000 for each violation, for each day that the violation existed, and for each employee affected. D. Many organizations have established standards that address lighting design, safety, performance, mounting, and testing, as well as illumination levels. Standards are norms or requirements that establish a basis for the common understanding and judgment of materials, products, or processes. 7 / 8 Q. How does OSHA define temporary? A. A permanent variance grants an alternative means of compliance with the requirements of a standard to employers who can prove that their methods, conditions, practices, operations, or processes provide workplaces that are as safe and healthful as those that follow the OSHA standards. B. With the Occupational Safety and Health Act of 1970, Congress created the Occupational Safety and Health Administration (OSHA) to ensure safe and healthful working conditions for workers by setting and enforcing standards and by providing training, outreach, education, and assistance. C. In any dark area that does not have permanent or temporary lights, where lights are not working, or where lights are not readily accessible, the employer shall provide portable or emergency lights and ensure that employees do not enter those areas without such lights. D. Temporary wiring may be used during the period of experimental or developmental work for a particular research project that is being conducted and until it has served the purpose for which installed at which time it must be removed immediately. 8 / 8 Q. What is a temporary light? A. Unlike permanent lighting, temporary lighting is installed on a job site for a limited amount of time. These sockets connect to bulbs using leads that are linked to an electrical connection or generator to establish temporary illumination. B. Permanent lighting, temporary lighting is installed on a job site for a limited amount of time.

Why is water extraction important? A. The most common causes of mold growing on walls are high humidity, condensation, and water leaks (which are often hidden inside the wall). Condensation forms when water vapor in the air meets cold surfaces and cools to become liquid. Leaking pipes near or inside of walls are a common cause of mold. B. To remove soot and smoke from walls, furniture, and floors, use a mild soap or detergent or mix 4 to 6 tbsp. tri-sodium phosphate and 1 cup household cleaner or chlorine bleach to every gallon of warm water. Wear rubber gloves. Be sure to rinse surfaces with clear warm water and dry thoroughly. C. Water extraction is an expert method using professional equipment to remove gallons of water from all areas of a building. The water extraction process will allow any office or home space to dry much faster than if it were left to dry on its own. It also helps prevent even more damage or mold growth in the building. D. Make a solution of about two thirds distilled white vinegar and one third water and use this to wash all hard surfaces, including the walls. Cigarette smoke leaves a greasy residue, and the vinegar will dissolve this. 2 / 10 Q. How much does it cost to extract water from carpet? A. On average, water damage restoration costs $2,400, but prices can reach as high as $4,250. The average price is broken down to $3.75-$7 per square foot, depending on the type of water and amount of damage done to the space. B. Most carpet cleaning pros can extract water from a carpet, which ranges from $150 to $500 per room, and then clean it thoroughly, which generally costs less than $1 per square foot of water damage repair costs. Carpets; $150 to $500 per room (plus $1/sq. ft.) C. The average amount homeowners will pay in water damage repairs is $2,582 — with a range from $1,074 and $4,090. Of course, all costs vary depending on the above factors. D. At $5 to $28 per square foot, drop ceilings are more expensive to install than drywall. Installing drywall costs $1 to $3 per square foot but that does not include painting prices, which are $2 to $6 for each square foot. 3 / 10 Q. The average costs for standard gray water damage extraction with drying and drywall and ceiling repairs in a home cost. A. Wall $300 - $2,200 B. Roof $400 - $1,000 C. Floor $600 - $20,000 D. Foundation $2,000 - $10,000 E. A. and B. F. All the Above. 4 / 10 Q. What are the types of extraction? A. Liquid–liquid extraction. B. Solid-phase extraction. C. Acid-base extraction. D. Supercritical fluid extraction. E. Ultrasound-assisted extraction. F. Heat reflux extraction. G. Mechanochemical-assisted extraction. H. Maceration. I. All the Above. 5 / 10 Q. What naturally absorbs moisture? A. Mothballs are used in locations to control pests other than clothes moths," Stone said. They include squirrels, skunks, deer, mice, rats, dogs, cats, raccoons, moles, snakes, pigeons and a variety of other animals. B. Rock Salt. Rock salt is a natural hygroscopic material that not only absorbs moisture, but also stores it — similarly to dehumidifiers. However, rock salt is completely natural, non-toxic and requires absolutely no electricity. ... There are many reasons why people love to use rock salt as a natural dehumidifier. C. Cedar chips offer a wide variety of benefits including insect control, moisture retention, and temperature control. Some property owners are hesitant to use cedar chips in their landscape beds because they lose their color and repellent qualities relatively quickly. D. Fly traps have smells that attracts flies is the smell we call “rot.” This includes things like decaying food, manure, and garbage. If you have old rotting fruit lying around your kitchen or garbage cans full of decaying meat or feces, flies can be brought buzzing your way. 6 / 10 Q. Is water damage covered by insurance? A. Homeowners insurance may help cover damage caused by leaks caused from plumbing. If the leak is sudden and accidental, such as if a washing machine supply hose suddenly breaks or if you come across a burst pipe, and or a leaking value from a toilet. However, homeowner’s insurance does not cover damage resulting from poor maintenance. B. Under a Homeowners Policy? Generally, most damage caused by wind in any type of storm is considered wind damage and is covered under a homeowner’s policy. Damaging winds can cause destruction to roofs, windows and more. C. Lightning strikes, as well as fire caused by lightning, are covered perils in almost all homeowner’s insurance policies, with no exclusions. ... Personal property, which can include electronics, appliances, furnishings, or other interior possessions damaged or destroyed by a lightning strike. D. Mold damage is only covered if it's related to a covered peril. Mold damage caused by flooding would need to be covered by a separate flood insurance policy. 7 / 10 Q. What is the process of extraction? A. Water extraction is the process of taking water from any source, either temporarily or permanently, for flood control or to obtain water for, for example, irrigation. ... Water can go through dams that are used to regulate or stop water from coming though, creating hydroelectricity. B. Water extraction is the process used to remove excess or standing water from your home or property. Restoration companies that specialize in water extraction work to minimize any damage to a home or business after flooding has happened. C. Extraction is a process in which one or more components are separated selectively from a liquid or solid mixture, the feed (Phase 1), by means of a liquid immiscible solvent, an atmospheric water generator (AWG) is a device that extracts water from humid ambient air. Water vapor in the air can be extracted by condensation - cooling the air below its dew point, exposing the air to desiccants, or pressurizing the air. Unlike a dehumidifier, an AWG is designed to render the water potable. D. All the Above. D. All the Above. 8 / 10 Q. Which method is used for water extraction? A. Vacuums – such as wet-dry vacuums can be used to eliminate excess water from areas such as floors, carpets, and surfaces that are porous. These vacuums work by putting down a cleaning solution and vacuuming up the moisture. B. Opening all water waste drains. C. Turning off all running water. D. Use a lot of towels and ring them out quickly. 9 / 10 Q. How does water extraction work? A. Water extraction involves removing excess water from a home through the use of submersible pumps and industrial vacuums. B. Opening all water waste drains. C. Turning off all running water. D.

What does it mean to winterize a house? A. Compared to the casual dust-up, a deep clean is an obsessive's agenda. It means hunting for dust mites behind furniture and cabinets, addressing scum from shower heads and faucets, scrubbing inside ovens, mopping floors under rugs, and sweeping along base boards, ceilings, and window frames. B. Winterization is the process of preparing a home for the harsh conditions of winter. It is usually performed in the fall before snow and excessive cold weather arrives. Winterization protects against damage due to bursting water pipes, and from heat loss due to openings in the building envelope. C. Measures taken to prevent fire from becoming destructive, reduce the impact of an uncontrolled fire, and save lives and property. D. About 40% of all homeowners have experienced a loss from water damage. It can spread contamination, ruin your paint, and damage your wood. The good news is that 93% of all water damage could have been prevented with the right knowledge. 2 / 10 Q. Will pipes freeze at 27 degrees? A. Why is it bad to leave water running, because it risks freezing the drain as it's leaving the sink, if the water main pipes are underground and aren’t deep enough below the surface, they can easily cause a freeze above ground, Burke warned. B. When a cold snap hover around or below 20 degrees Fahrenheit (-6 degrees Celsius), it's time to let at least one faucet drip. Pay close attention to water pipes that are in attics, garages, basements, or crawl spaces because temperatures in these unheated interior spaces usually mimic outdoor temperatures. C. There is no simple answer. Water freezes at 32 degrees Fahrenheit, but indoor pipes are somewhat protected from outdoor temperature extremes, even in unheated areas of the house like in the attic or garage. As a rule, temperatures outside must drop to at least twenty degrees or more to cause the pipes to freeze. D. It's important to note that pipes do not always burst once they're frozen or while in the process of freezing, after a pipe has frozen and begins to thaw, the pressure caused by the water that begins to rush through the pipe threatens to cause a pipe to burst. 3 / 10 Q. How long does it take for pipes to freeze at 10 degrees? A. General rule, temperatures outside must drop to at least 20 degrees or lower to cause pipes to freeze. In northern climates, where the temperatures regularly fall below freezing, modern homes tend to be well insulated and water pipes are located on the inner parts of the house for extra protection. B. The basic rule of thumb is to generally expect pipes to freeze within 3 – 6 hours of drawn-out subnormal temperatures. C. You might be tempted to wait for the pipes to thaw out by themselves. But keep in mind: Depending on the weather, the process can take days. Pipes typically don't freeze until the temperature dips to 20 degrees Fahrenheit. D. PVC pipes are in danger of freezing when surrounding temperatures approach 20 degrees Fahrenheit. ... Water damage from a burst pipe is expensive. To avoid dealing with burst pipes, prevent them from freezing. Some advanced planning will assist you in keeping your pipes intact during winter months. 4 / 10 Q. How much does it cost to winterize your home? A. When water freezes, it expands as it becomes ice. This expansion produces pressure within pipes, which causes damage. Winterizing plumbing is recommended when a house will be vacant for a long period of time and no water will be running through the pipes. B. Some companies will winterize a vacant home for around $200. In most cases, you can do it yourself for less than $20. Others make it a point that it is the buyer's responsibility, hence you have to pay for the property to get de-winterized. Note: this runs $50 to $150 and the cost to re-winterize is $125 – $350. C. So, no matter how long you'll be away, the setting that's best for home maintenance is 85 degrees in the summer and 50 degrees in the winter. D. At night and when you are away, it is recommended to just turn your thermostat down 7-10 degrees lower than what you would typically have the heat set at. By doing this, the U.S. Department of Energy states you can save as much as 10% a year on heating. 5 / 10 Q. Is it safe to put antifreeze in pipes? A. Antifreeze last in pipes, if it is closed properly, it should last between 1-5 years, and you can use it any time during that period. B. Antifreeze will keep pipes from freezing if all water cannot be removed, add antifreeze to prevent any water from freezing and cracking the toilet. Check all sink and tub drains that could have drain traps. Add some antifreeze to each one of them to prevent water from freezing and cracking in the traps. C. Automotive antifreeze uses ethylene glycol which is not okay for home sewage systems. Use antifreeze in wastewater or hot water heating systems only if it is not practical to maintain heat in the home, insulate the vulnerable pipes or keep water trickling through the system. D. RV antifreeze will last as long as it's stored properly and the cap is tightly sealed, RV antifreeze will typically have a shelf life between 1 to 4 years but can often remain effective long after that. Most brands will have an expiration date as well to help guide you. 6 / 10 Q. How cold does it have to be in your house for the pipes to freeze? A. Generally, expect pipes to freeze within 3 – 6 hours of drawn-out subnormal temperatures. Now, the keyword here is the temperature because we have a specific threshold below which your pipes are particularly in danger of freezing and probably breaking. B. 20 degrees Fahrenheit. Typically, your home's pipes begin to freeze when the outside temperature is at least 20 degrees Fahrenheit. Again, this depends on your geographical location. For example, areas that expect lower temperatures have water pipes that are better insulated in inner parts of your home, compared to other areas. C. You leave a faucet dripping? Yes, it's recommended you leave a faucet on with water at a drip to keep pipes from freezing. If you know where the water comes into your house, turn on a faucet at the opposite end to keep the water circulating. D. You can unfreeze a frozen drainpipe by pouring hot water down it. Fill a pot with a half-gallon of water and heat it on the stove. When it begins to boil, carefully remove it from the stove and slowly pour it down the drain. This may be enough to thaw the ice and completely clear your drain. 7 / 10 Q. What type of antifreeze is used to winterize a house? A. Minimum temperature to keep pipes from freezing, the absolute minimum temperature to keep pipes from freezing is 55° F. However, between 60° F and to 68° F is a much safer range. This ensures that the air around your pipes is warm enough to prevent freezing. B. There are three main types of coolant that car companies use: Inorganic Additive Technology (IAT), Organic Acid Technology (OAT), and Hybrid Organic Acid Technology (HOAT). Typically, older cars use IAT. It needs to be changed every two years or 24,000 miles, making it far inferior to newer formulas. C. Trap is located underneath the drain of each sink and is meant to constantly hold water acting as a plug to prevent sewer gases from entering the home. Go to each sink, get plumber's antifreeze and pour about a 1/2 cup down each drain. D. Use only RV antifreeze to winterize your home. It is non-flammable and non-toxic. NEVER use automobile antifreeze as it is highly toxic, see text to the right. NEVER use plumbing antifreeze with copper lines, drains or motor parts. 8 / 10 Q. How do you winterize indoor faucets? A. One of the best plumbing winterization tips is as easy as turning on the faucet. B. Insulate pipes. C. Mind the temperature. D. Circulate warm air. E. Keep out the cold. F. Seal air leaks. G. All The Above. 9 / 10 Q. What is de-winterize? A. Adjust your thermostat. Set your thermostat (don't turn it off) at the lowest temperature that will keep your pipes from freeze damage (at least 50 to 55 degrees should do it). You want it warm enough to keep your pipes or anything else from freezing. B. While you may not want to drain the system and or full the system up until you are sure a late freeze is out of the question, the warm/cool days of early spring are the perfect time to get a jump on the rest of the spring commissioning processes. C. A sprinkler blowout is usually best done in October in the northern climate of the United States. When to turn off your sprinkler, however, can be a delicate balance of good timing and luck. Do it too early, and your lawn may lose precious water it needs to prepare for the winter. D. Shut off the water supply to the irrigation system. The main shut off valve for your irrigation system needs to be protected against freezing. Make sure it is wrapped with insulation (foam insulation tape and a plastic bag) to protect it from harsh winter temperatures and prevent it from freezing. 10 / 10 Q. When should you de-winterize? A.

According to Industry, air scrubbers can remove 99% of these airborne particles. B. While the filters can't eliminate common allergy triggers like dust, dirt, pollen and pet dander, the best air purifiers will help boost the overall air quality in your home, hopefully helping to reduce some of the nastier allergy symptoms and helping you breathe a little easier. C. When used properly, air cleaners and HVAC filters can help reduce airborne contaminants including viruses in a building or small space. By itself, air cleaning or filtration is not enough to protect people from COVID-19. D. An air purifier can also make a big difference in flu prevention, especially during flu season, when all around you are putting flu virus into the air with their sneezes. 4 / 10 Q. Do dehumidifiers kill mold? A. So, to answer your question, dehumidifiers do NOT kill mold, but they do prevent it by reducing humidity. If you have a mold problem in your home, do not wait. Remove the mold and stop the moisture source (leak, condensation, high humidity, etc.) to prevent more damage and costly repairs. B. There are no scientific guidelines about the use of humidifiers to prevent flu, the germs may be able to survive in the drier air conditions. So, the thought is that, if you keep the humidity level up in a room, the virus is less likely to survive. C. One method to kill fleas naturally is to use dehumidifiers to remove moisture from the area. If you can keep the average room humidity down around 50 percent for at least two days or more, you'll kill most of the adults, pupa, and larva. D. Plants need moisture from the soil or air to complete the photosynthesis equation. ... However, even those with high humidity levels that regularly use a dehumidifier, won't kill their plants – providing they're the right plants; cared for, watered, and shown some indirect sunlight from time to time. 5 / 10 Q. How long should I run an air scrubber? A. Are Air Scrubbers Really That Effective? Nothing is 100% effective, but air scrubber technology comes close. Some models can eliminate up to 90% of airborne microorganisms, as well as 99% of surface microorganisms, including black mold, Staph and MRSA. B. An air scrubber can remove mold spores if it has a true HEPA filter and enough air flow. Many air scrubbers are for gas removal A true HEPA air purifier is generally a better solution for mold removal. C. The industry guideline recommends that an air scrubber be in the environment for 24 to 48 hours to thoroughly scrub the air. These types of air devices usually do between 4 to 6 air exchanges per hour which will effectively aid in the filtration and cleaning of the airspace. D. So, a minute on and a minute off has always been the minimum rule of thumb. Two minutes on and two minutes off is just that much better for the motor. With the old conventional pressure tank method, the pressure tank fills at the rate the pump can produce, less the amount of water being used at the time. 6 / 10 Q. Do air scrubbers kill mold? A. Air purifiers and scrubbers make the air safer by filtering out floating contaminants. That includes common allergens such as tobacco smoke, dust, and pollen. They don't reduce the humidity. Most use some sort of mechanical filter that needs occasional cleaning or replacement. B. A solution of diluted bleach provides the fastest way to kill mold on walls or flooring. Prepare the solution by adding one cup of bleach into a bucket that contains about a gallon of warm water. Then proceed to scrub the mold vigorously with a stiff-bristled brush you've dipped in the bleach solution. C. Yes. Air scrubbers remove a variety of pathogens and contaminants, including mold. They can also remove allergens like dust mites, pollen, and mold spores. Air scrubbers can remove 99% of these airborne particles. D. Water pump that employs both a motor and an impeller for the water pumping process. During the water pumping, the impeller spins very fast. The pressure then causes the water to jet forward in a high-speed manner out of the impeller. 7 / 10 Q. How many air scrubbers is needed per job? A. The pump is powered by an electric motor that drives an impeller, or centrifugal pump. The impeller moves water, called drive water, from the well through a narrow orifice, or jet, mounted in the housing in front of the impeller. ... Its function is to slow down the water and increase the pressure. B. As a rule, you should achieve a minimum of 6 ACH. This means that an air scrubber must complete six air changes every hour, or one every ten minutes. If you can increase the ACH, do so. You can see that you would need an air scrubber with 400 CFM to maintain 6 ACH in a 4,000 cubic foot space. C. There is no need to keep the dehumidifier running constantly. It's generally enough to run the unit when the humidity level is 50% or higher. A good rule of thumb to remember is to maintain a comfortable 30-50% humidity level for most homes. D. The industry guideline recommends that an air scrubber be in the environment for 24 to 48 hours to thoroughly scrub the air. These types of air devices usually do between 4 to 6 air exchanges per hour which will effectively aid in the filtration and cleaning of the airspace. 8 / 10 Q.

Is crawl space encapsulation necessary? A. Radon will exist in every old home, new home, drafty home, well insulated home, and homes with and without basements. If any part of your foundation is in direct contact with the soil, it has the potential of having elevated levels. B. Most research agrees that ideal crawl space wood moisture content should be between 10% and 16%. Wood moisture levels will vary some, but they should not remain too low or too high. C. If you smoke and live in a home with high radon levels, you increase your risk of developing lung cancer. D. Moisture in your crawl space will only lead to structural damage over time. The vapor within the crawl space can rot your home's wooden frames and flooring. Encapsulating the crawl space keeps away moisture. In addition, encapsulation helps keep dangerous pests like termites out. 2 / 11 Q. Does a sealed crawl space need a dehumidifier? A. Every encapsulated crawlspace needs a drying mechanism.

Typically, mold damage is only covered if it's related to a covered peril. Mold damage caused by flooding would need to be covered by a separate flood insurance policy. Even though crawl space encapsulation isn't covered by your homeowner’s insurance, it can still be a worthwhile investment. It's a measure that can make it more difficult for standing water to build up in the first place and it also makes it easier to remove water that does pool in the foundation of your home. C. Radon is a radioactive gas you can't see, feel, taste, or smell. It starts out as uranium, a heavy metal found in the ground and most rocks on the planet. D. As mold grows underneath your home in the crawl space, the air that circulates from your crawl space eventually finds its way into your home. Most insurance policies do not cover mold damage due to moisture, flooding, or preventable leaks. 4 / 11 Q. How much does it cost to install a radon mitigation system? A. Radon mitigation system cost varies dramatically depending on how the home is constructed. Radon system costs can range from $750 to $5,000 per home.

A radon mitigation solution for a crawlspace is to use a standard 6 mil polyethylene vapor barrier, which works, but contractors may be required by law to use a fire-rated membrane. B. If you smoke and live in a home with high radon levels, you increase your risk of developing lung cancer. C. Radon will exist in every old home, new home, drafty home, well insulated home, and homes with and without basements. If any part of your foundation is in direct contact with the soil, it has the potential of having elevated levels. D. Radon levels are usually higher in basements, cellars and living spaces in contact with the ground. However, considerable radon concentration can also be found above the ground floor. Radon concentrations vary considerably between adjacent buildings, as well as within a building from day to day and from hour to hour. 6 / 11 Q. What is crawl space mitigation? A. Radon gas does not just stay in the basements or crawl spaces. If there is radon problem in your home, there is a problem throughout your entire home, including your most lived in areas like the living room, bedrooms, and kitchen. B. If you smoke and live in a home with high radon levels, you increase your risk of developing lung cancer. C. The mitigation system creates a constant vacuum in this soil to vent the radon out above the roof of the house. Many homes have a combination of crawlspaces, slab-on-grade areas, and basements. These homes are treated using a radon mitigation system with several different suction points. D. Radon will exist in every old home, new home, drafty home, well insulated home, and homes with and without basements. If any part of your foundation is in direct contact with the soil, it has the potential of having elevated levels. 7 / 11 Q. How long does crawl space encapsulation last? A. This can be a severe problem in crawlspaces without vapor barriers and without adequate ventilation. But the solution is often simply to lay a vapor barrier over the ground, which is a much less expensive fix than dealing with major groundwater problems. B. Radon will exist in every old home, new home, drafty home, well insulated home and homes with and without basements. If any part of your foundation is in direct contact with the soil, it has the potential of having elevated levels. C. Radon gas does not just stay in the basements or crawl spaces. If there is radon problem in your home, there is a problem throughout your entire home, including your most lived in areas like the living room, bedrooms, and kitchen. D. Between 15 and 20 years for a typical crawlspace encapsulation project. However, if the humidity levels are controlled and no catastrophic events such as flooding occur, a properly encapsulated crawlspace can last for more than 20 years. 8 / 11 Q. How often is radon found in homes? A. Radon levels are usually higher in basements, cellars and living spaces in contact with the ground. However, considerable radon concentration can also be found above the ground floor. Radon concentrations vary considerably between adjacent buildings, as well as within a building from day to day and from hour to hour. B. Radon will exist in every old home, new home, drafty home, well insulated home and homes with and without basements.

If there is radon problem in your home, there is a problem throughout your entire home, including your most lived in areas like the living room, bedrooms, and kitchen. D. It's common: About 1 in every 15 homes has what's considered an elevated radon level. The gas is odorless and invisible, says the EPA, and it causes no immediate symptoms, so the only way to know if your home is affected is by testing your individual residence. 9 / 11 Q. How expensive is foundation repair? A. Average foundation repair cost for homeowners is typically just over $4000, or between $1800 and $6500.
