How to live safely with asbestos-containing materials? Dangers of asbestos One of the most widespread uses of asbestos in the construction industry is the creation of fiber-cement sheets for roofing, which we often call Phibroximang, or asbestos-cement corrugated iron. Because of its heat-resistant and fire-resistant properties, asbestos has been added to many roofing products, including tiles. Fiber cement board contains not only asbestos. They are mostly made from cement. According to manufacturers, fiber cement panels are usually made of 10-15% asbestos. The most common way for asbestos fibers to enter the body is through the airways. In fact, asbestos-containing material is not generally considered harmful unless it releases dust or fibers into the air where they can be inhaled or ingested. Much of the fiber gets stuck in the mucous membranes of the nose and throat, where it can be eliminated, but some can travel deep into the lungs, or if swallowed, into the digestive tract. Once they get trapped in the body, the fibers can cause health problems. Asbestos is most dangerous when it is flaking. The term “friable” means that asbestos is easily broken up by hand, releasing fibers into the air. Asbestos is often “faded” after the roofing sheet is used for a number of years, rain, wind and moss make the protective cement layer rot. Damage and deterioration will increase the friability of asbestos-containing materials. Water damage, constant shaking, aging and physical impact such as drilling, grinding, polishing, cutting, sawing or impact can break materials making it easier to release fibers. Ceiling tiles, floor tiles containing asbestos, heat and sound insulation layers, shingles, fire doors, especially roofing sheets… will not release asbestos fibers unless they are disturbed or damaged as mentioned above. . For example, if asbestos ceiling tiles are drilled or broken, it can release fibers into the air. If it is left alone and undisturbed, it will not release the asbestos fibers, but this is very unlikely in practice, for example, when roofing sheets are used for a long time. Currently, there is no decision requiring removal of asbestos roofs, so the decision is up to the community. Obviously, it will be necessary to take into account the cost of removal and replacement. Therefore, for new roofs, it is not necessary to remove, but can live with it, provided that there are safe solutions. But with a weathered roof, there is a great risk of deterioration, which can expose families and neighbors of homes with asbestos to harmful asbestos fibers. Theoretically, in roofing, asbestos materials mixed with cement should be kept tight, they do not pose the same threat as fragile materials to human health. However, if these roofing sheets are broken, corroded, disturbed, damaged, degraded or broken, they can release toxic fibers into the air and become hazardous. Corrosion of asbestos-containing products by weather (rain, sun, wind, storm or frost, which causes a change in the cement layer surrounding the asbestos fiber over time) can cause fiber release in within 15 years. Safe living with asbestos When living with irreplaceable asbestos-containing material, it should be checked regularly for signs of wear or damage such as tears, scratches or water damage. If asbestos-containing materials are damaged more than mildly, or if home repairs are being made that could disturb it, extreme care should be taken and handling it in accordance with safety regulations. When asbestos-containing material is damaged, activities around it should be kept to a minimum. Take all precautions to avoid damage to the asbestos material. With any type of repair, the asbestos must be kept in place. Repair is usually cheaper than removal, but it can make later removal of asbestos, inevitably, more difficult and costly. Major repairs should only be carried out by specialized units that know the safe handling methods of asbestos. Before performing minor repairs, be sure to follow all of the precautions outlined above. Always wet the asbestos material using a fine mist of water containing a few drops of detergent. Areas with insulation can be covered by wrapping a special fabric, such as flexable glass cloth, around it. These products are available in stores. This is the best, safest, economic thing possible. We should replace asbestos-containing materials with other materials, such as: corrugated iron roof, PVA fiber roof, steel pipes… Currently, on the market, there are many alternative materials that are both durable and good. no effect on health and reasonable price. What not to do with asbestos-containing materials in the home: Do not dust, sweep, or vacuum debris that may contain asbestos. Do not saw, sand, scrape or drill holes in the face of the asbestos material. Do not use sandpaper, wire brush or other hard objects to remove rough spots on the surface of asbestos-containing materials. Never use the wiper on dry floors. Do not sand or attempt to smooth the floor with asbestos or its substrate. When asbestos floors need to be replaced, install new floor coverings on top if possible. Avoid contact with broken or broken asbestos materials. Take all precautions to not damage any materials that may contain asbestos. Only hire trained personnel to inspect, test, repair or remove asbestos. Asbestos is a toxic and dangerous mineral. Asbestos in all natural forms, including chrysotile asbestos, is a substance with proven carcinogenic activity in animals and humans, capable of causing cancer of the lungs, peritoneum, pleura, stomach and organs other in contact with asbestos particles. Temporarily without replacement, it is possible to live with asbestos-containing material, if it is not old (before 15 years), but with extreme caution. To reduce the risk of cancers, asbestos-containing materials should be removed, if temporarily unavailable, protect it with a coating or polyethylene film to prevent damage and dust release.

The current fireproof materials market is also very diverse and developed. Depending on the function of use, fireproof materials are arranged to ensure safety as well as in accordance with the construction budget. According to the advice of architect Bui The Long (CTA | Creative Architects), fireproof materials are special materials, so it will need professional advice to ensure safety and suitability. In addition, homeowners need to avoid widespread use, causing waste because fireproof materials are quite expensive. However, using fire prevention materials is only the last step to preserve the life and property of users. First of all, it is still necessary to ensure fire prevention from the beginning of construction such as arranging safe and suitable functional areas, arranging reasonable exit doors … For good fire protection for the house, homeowners need to make sure from the first step of construction. For the kitchen area, homeowners need to choose non-combustible materials such as stone, insulation panels, heat-resistant glass… At the same time, homeowners should switch to using induction or infrared stoves to reduce the risk of fire and explosion from gas stoves as well as when using stoves with a capacity of more than 4000W. In addition, the homeowner needs to install a self-cutting circuit breaker and attached safety wires. As for spaces such as karaoke rooms, indoor movie screenings, homeowners should use soundproofing and fireproof materials such as fireproof glass wool. Because these areas have a high risk of fire due to the arrangement of carpets, fabrics, cotton, etc. for drainage and soundproofing.

Even the first pilot to land on a warship was carrying safety gear: Eugene Ely, attempting to land on the deck of the armored cruiser USS Pennsylvania in 1911, was flying Curtiss Pusher, wearing a leather soccer helmet, eyeglasses, and a makeshift life jacket made of bicycle tubes. The probability of the pilot being forced to end the mission with a parachute launch from the cockpit is very small – it happened exactly 1.33 times per 100,000 flight hours, according to the US Navy. But naval aviation officers still carry equipment for such a scenario. “Most equipment is used only in emergencies,” said Lt. Luke “Oslo” DeLisio, a flight officer from the 106th Strike Squadron. Inside, the pilot wears a cotton bra. In the event of a fire in the cockpit, the cotton will not melt and stick to the skin like nylon or polyester. In terms of underwear, the pilots wore a one-piece CWU 27 / P Nomex suit. Developed by the DuPont company in the 1960s, Nomex is a synthetic flame retardant that can withstand heat and flash (a form of electrical discharge) up to 400 degrees Celsius. When the Nomex suit encounters high temperatures, the fibers Its thickens and carbonizes, absorbing heat. The standard color of the CWU 27 / P is sage green, but the American pilots who served in the Persian Gulf area and nearby wore desert brown. The flight suit is a one-piece, zippered front jumpsuit design to ensure limited exposure to fire. DeLisio says it’s a comfortable fit. “We call it” pocket “. No need, this thing is ready-made, just stick the stickers in and go. It’s almost like wearing your pajamas to work. ” Equipped with a velcro and eight pockets (including a zippered arm pocket with a separate cap for holding the pen), the flight suit is standard work attire both on and off the plane. “I usually keep my wallet and canvas hat in my leg pocket,” says DeLisio that most other bags are difficult to reach while flying. Other pilots use arm pockets to carry their mission cards and a pen or two. American pilots are also equipped with long, fireproof GS / FRP-2 gloves. US Navy Lieutenant Alexander Klapka carries all the equipment an F-18 pilot wears. Why are most pilots not wearing black shoes? The carrier deck is like a construction site – there is always a risk of something falling or rolling over the pilot’s feet while he is on deck. The pilot wears military-issued or separately purchased leather boots (but approved by the US Navy) with steel toes protected. Integrated steel reinforcement protects the pilot’s toes when parachuting from the plane. High ankle support is a must for rough grounding. While a sports parachute slows a person down to about 5m / sec, a person falls in a faster military parachute – around 7.3m / sec. Each pilot has a preference for footwear, but DeLisio wears Bellville flying shoes that are issued by the naval air force. He says he has worn multiple pairs, but adds one difference: “My shoes are always brown.” Navy pilots are in constant debate about the color of the shoe – black or brown. “ A guy in black shoes is usually a guy working on deck, ” says DeLisio. Pilots tend to wear brown shoes, but some people still wear black shoes. Top Gun and Blue Angels show crew pilots still wear black boots, but brown stubbles are more common among fighter pilots. Outside of the flight suit, a pilot wears a CSU-15A / P. G-suit, which, as the name suggests, has airbags that compress the pilot’s legs and abdomen, helping to retain blood in the brain. of the pilot in high-speed maneuvers. Pilots can withstand six times the force of gravity without wearing a G suit, but the CSU-15A / P suit allows a typical F / A-18 fighter pilot to perform maneuvers. with a gravitational acceleration up to 7.6 G before losing consciousness due to this force.

Check the humidity at the foot of the forest of U Minh National Park in the morning of April 15.

At noon April 15, the sudden rain lasted about 10:30 a.m. to 13 p.m., helping to cool down the hot sun on the forest stands of U Minh low-cut cajuput forest.

It is also a rare unseasonal rain from the beginning of the dry season 2020-2021 up to now in Ca Mau. Rain lowers the hot summer noon heat, increases humidity and adds a significant amount of water to canals and ditches in the forest stand of Ca Mau Melaleuca forest. But according to the force that is directly in charge of the “fire watch” task in the dry season, the off-season rain often has lightning that causes the forest fire, but it is very difficult to fight the fire and extinguish the fire, because the tree trunk and leaves have been cleared of dust.

The possibility of lightning causing fire is also a concern of the Secretary of the Provincial Party Committee, Chairman of the People’s Council of Ca Mau province Nguyen Tien Hai, during a visit to the inspection of forest fire prevention and fighting (FPF) in the forest stand of U Minh Ha Melaleuca forest. on the morning of April 15.

Talking with forest owners in U Minh, Provincial Party Secretary cited many fires caused by lightning at the beginning of the rainy season. Therefore, the forest owners must not ignore and lose their guard against the early rains of the season. “Fire is caused by humans, we can be prevented by good control, but due to lightning, we can only detect it in time to extinguish, prevent big fires from happening” – Secretary of the Ca Mau Provincial Party Committee noted and requested the ” forest owners ”need to be more professional in forest management and protection. Specifically, in 2022, at all costs, the forest management and protection units in U Minh must install specialized cameras (magic eyes), and at the same time purchase unmanned aerial vehicles for monitoring and management. forest management and protection, as well as forest fire prevention and fighting.

Out-of-season rain increases the risk of fire in the stand of Ca Mau Melaleuca forest.

Up to the present time, the entire forest stand of Ca Mau Melaleuca forest has been drought, the risk of forest fire at any time. Among them, level IV fire alarms (dangerous level) are more than 19,480 ha and grade V (extremely dangerous level) is nearly 8,000 ha, accounting for more than 61% of the total area of ​​the stand.

Areas with level 5 fire alarm forests are concentrated in: The Melaleuca forest part of U Minh Ha Forestry Company Limited; U Minh Ha National Park; Ca Mau Agricultural Seed Center; The wartime headquarters of the Military Command of Ca Mau province; forest stand in the communes of Nguyen Phich, Khanh An, Khanh Lam, Khanh Thuan … of U Minh district. The most worrying of forest owners is that the heat continues to be fierce, causing water under canals to evaporate faster, and there is a possibility that there will be a shortage of fire fighting water if a big fire occurs in some areas of the forest stand of Ca Mau Melaleuca forest.
