Bambi Bucket
A helicopter bucket or helibucket is a specialized bucket suspended on a Wire rope, cable carried by a helicopter to deliver water for aerial firefighting. The design of the buckets allows the helicopter to hover over a water source—such as a lake, river, pond, or Water tank, tank—and lower the bucket into the water to refill it. This allows the helicopter crew to operate the bucket in remote locations without the need to return to a permanent operating base, reducing the time between successive drops. Each bucket has a release valve on the bottom which is controlled by the helicopter crew. When the helicopter is in position, the crew releases the water to extinguish or suppress the fire below. Each release of the water is referred to as a drop. Design Buckets can be collapsible or rigid and vary in capacity from . The size of each bucket is determined by the lifting capacity of the helicopter required to utilise each version. Some buckets can include fire retardant foam or ...

Fire Retardant Foam
Firefighting foam is a foam used for fire suppression. Its role is to cool the fire and to coat the fuel, preventing its contact with oxygen, thus achieving suppression of the combustion. Firefighting foam was invented by the Moldovan engineer and chemist Aleksandr Loran in 1902.Loran and the fire extinguisher at p-lab.org The s used must produce foam in concentrations of less than 1%. Other components of fire-retardant foams are organic s (e.g., trimethyl- trimethylene glycol and [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wildfire Suppression Equipment
A wildfire, forest fire, or a bushfire is an unplanned and uncontrolled fire in an area of combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire ( in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Some natural forest ecosystems depend on wildfire. Modern forest management often engages in prescribed burns to mitigate fire risk and promote natural forest cycles. However, controlled burns can turn into wildfires by mistake. Wildfires can be classified by cause of ignition, physical properties, combustible material present, and the effect of weather on the fire. Wildfire severity results from a combination of factors such as available fuels, physical setting, and weather. Climatic cycles with wet periods that create substantial fuels, followed by drought and heat, often precede severe wildfires. These cycles have been intensified by climate change,Pa ...

Cargo Hook (helicopter)
A cargo hook is a device suspended below a helicopter and allows the transport of external loads during flight. Common terms for this operation include slingwork, underslung loads, external loadwork, and external load operations. Hook types Primary hooks Primary, or "belly", hooks are designed to mount directly to the airframe belly, i.e. underside, of a helicopter. Because they are attached to the fuselage, or "skin," of the aircraft, belly hooks are regulated by the various worldwide civil aviation authority, aviation regulatory agencies. In the United States, belly hooks are governed under Federal Aviation Administration (FAA) Federal Aviation Regulations, FAR Part 133. Belly hooks are designed, manufactured, and approved for use on specific aircraft models. Belly hooks that have been certified by the FAA receive a Type certificate#Supplementary/Supplemental Type Certificate (STC), Supplemental Type Certificate (STC) that describes the aircraft models that are authorized ...

Helitack
Helitack crews are teams of wildland firefighters who are transported by helicopter to wildfires. Helicopters provide rapid transport, enabling helitack crews to quickly respond and assess a wildfire situation. Helitack crews may land near a wildfire or, if equipped and trained, rappel from a hovering helicopter. Once on the ground, crews build firelines using hand tools, chainsaws, and other firefighting tools. They often remain overnight in remote locations. After they have completed their assignment, crew members may pack up to 120 pounds of equipment over difficult terrain to reach a pick-up point. Rappellers often prepare helispots (helicopter landing zones) that provide better access to a fire. Helicopter crew members may also perform other duties such as tree falling, firing operations, and managing helibases. Terminology Helitack The term ''helitack'' first appeared in a 1956 ''Los Angeles Times'' article, which described the "first of a series of tests—tabbed the He ...

Helicopter Rescue Basket
A helicopter Litter (rescue basket), rescue basket is a basket suspended below a helicopter in order to rescue people from a fire or other disaster site. Uses There are two main types of helicopter baskets. The smaller, more common type is used by rescuers to lift a person up from ground or water into the helicopter. An early type that could scoop an unconscious person from the sea was the Sproule Net, invented by Lt Cdr John Sproule, RN, in 1956 which was used by British helicopter rescue units until the late 1970s. The second type is a new invention. This is a basket able to fit five people or more. It allows a large group of people to be rescued from a fire or other emergency site, without needing to load them into the helicopter itself. It enables the helicopter to load a large group without landing. The helicopter hovers over the site and rests the basket on the ground or other surface. Evacuees board, then are transported to a safe area. This type of basket was tested b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Generic Trademark
A generic trademark, also known as a genericized trademark or proprietary eponym, is a trademark or brand name that, because of its popularity or significance, has become the generic term for, or synonymous with, a general class of products or services, usually against the intentions of the trademark's owner. A trademark is prone to genericization, or "genericide", when a brand name acquires substantial market dominance or mind share, becoming so widely used for similar products or services that it is no longer associated with the trademark owner, e.g., linoleum, bubble wrap, thermos, and aspirin. A trademark thus popularized is at risk of being challenged or revoked, unless the trademark owner works sufficiently to correct and prevent such broad use. Trademark owners can inadvertently contribute to genericization by failing to provide an alternative generic name for their product or service or using the trademark in similar fashion to generic terms. In one example, the Oti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bucket
A bucket is typically a watertight, vertical Cylinder (geometry), cylinder or Truncation (geometry), truncated Cone (geometry), cone or square, with an open top and a flat bottom that is attached to a semicircular carrying handle (grip), handle called the ''Bail handle, bail''. A bucket is usually an open-top container. In contrast, a Pail (container), pail can have a top or lid and is a shipping container. In non-technical usage, the two terms are often used interchangeably. Types and uses A number of bucket types exist, used for a variety of purposes. Though most of these are functional purposes, a number, including those constructed from precious metals, are used for ceremonial purposes. Common types of bucket and their adjoining purposes include: * Water buckets used to carry water * Household and garden buckets used for carrying liquids and granular products * Elaborate ceremonial or ritual buckets constructed of bronze, ivory or other materials, found in several ancient ...

Water Tank
A water tank is a container for Water storage, storing water, for many applications, drinking water, irrigation, fire suppression, farming, both for plants and livestock, chemical manufacturing, food preparation as well as many other uses. Water tank parameters include the general design of the tank, and choice of construction materials, linings. Various materials are used for making a water tank: plastics (polyethylene, polypropylene), fiberglass, concrete, stone, steel (welded or bolted, carbon, or stainless). Earthen pots, such as matki (earthen pot), matki used in South Asia, can also be used for water storage. Water tanks are an efficient way to help developing countries to store clean water. History Throughout history, wood, ceramic and stone tanks have been used as water tanks. These containers were all naturally occurring and some man made and a few of these tanks are still in service. The Indus Valley civilization (3000–1500 BC) made use of granary, granaries and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
