Avalanche Rescue
Avalanche rescue involves locating and retrieving people who have been buried in avalanches. Prevention There are several ways to prevent avalanches and lessen their power and destruction. They are employed in areas where avalanches pose a significant threat to people, such as ski resorts and mountain towns, roads and railways. Explosives are used extensively to prevent avalanches, especially at ski resorts where other methods are often impractical. Explosive charges are used to trigger small avalanches before enough snow can build up to cause a large avalanche. Snow fences and light walls can be used to direct the placement of snow. Snow builds up around the fence, especially the side that faces the prevailing winds. Downwind of the fence, snow buildup is lessened. This is caused by the loss of snow at the fence that would have been deposited and the pickup of the snow that is already there by the wind, which was depleted of snow at the fence. When there is a sufficient d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avalanche Warning In Tuckerman
An avalanche is a rapid flow of snow down a Grade (slope), slope, such as a hill or mountain. Avalanches can be triggered spontaneously, by factors such as increased precipitation or snowpack weakening, or by external means such as humans, other animals, and earthquakes. Primarily composed of flowing snow and air, large avalanches have the capability to capture and move ice, rocks, and trees. Avalanches occur in two general forms, or combinations thereof: slab avalanches made of tightly packed snow, triggered by a collapse of an underlying weak snow layer, and loose snow avalanches made of looser snow. After being set off, avalanches usually accelerate rapidly and grow in mass and volume as they capture more snow. If an avalanche moves fast enough, some of the snow may mix with the air, forming a powder snow avalanche. Though they appear to share similarities, avalanches are distinct from slush flows, Mudflow, mudslides, Landslide#Debris landslide, rock slides, and serac collap ...

References
A reference is a relationship between Object (philosophy), objects in which one object designates, or acts as a means by which to connect to or link to, another object. The first object in this relation is said to ''refer to'' the second object. It is called a ''name'' for the second object. The next object, the one to which the first object refers, is called the ''referent'' of the first object. A name is usually a phrase or expression, or some other Symbol, symbolic representation. Its referent may be anything – a material object, a person, an event, an activity, or an abstract concept. References can take on many forms, including: a thought, a sensory perception that is Hearing (sense), audible (onomatopoeia), visual perception, visual (text), olfaction, olfactory, or tactile, emotions, emotional state, relationship with other, spacetime coordinates, symbolic system, symbolic or alpha-numeric grid, alpha-numeric, a physical object, or an energy projection. In some cases, meth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snow Shovel
A snow shovel is a specialized shovel designed for snow removal. Snow shovels come in several different designs, each of which is designed to move snow in a different way. Removing snow with a snow shovel has health and injury risks, but can also have significant health benefits when the snow shovel is used correctly. History The earliest known snow shovel was found in a bog in Russia. Estimated to be 6,000 years old, its blade was made from a carved elk antler section. According to archaeologists, the antler piece was tied to a wood or bone handle. Features All snow shovels consist of a Handle (grip), handle and a scoop. Sometimes there may be a shaft connecting handle and scoop, while in other snow shovels, the handle is extended and attaches directly to the scoop. Most snow shovels are designed for either pushing snow or lifting snow, although some are crossovers which can do either job. Some snow shovel scoops have sharpened blades which can chip away and lever up slabs o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Backcountry Skiing
Backcountry skiing ( US), also called off-piste (Europe), alpine touring, freeriding or out-of-area, is skiing in the backcountry on unmarked or unpatrolled areas either inside or outside a ski resort's boundaries. This contrasts with alpine skiing, which is typically done on groomed trails benefiting from a ski patrol. Unlike ski touring, backcountry skiing can – and often does – include the use of ski lifts including snowcats and helicopters. Recent improvements in equipment have increased the popularity of the sport. As the sport does confront the individual practicing it with the dangers of natural, unprepared alpine terrain like avalanches, it is generally recommended to carry standard safety equipment and to learn beforehand how to behave safely under such conditions. Terminology The terms "backcountry" and "off-piste" refer to where the skiing is being done, while terms like ski touring, ski mountaineering, telemark, freeriding, and extreme skiing describ ...

Hypothermia
Hypothermia is defined as a body core temperature below in humans. Symptoms depend on the temperature. In mild hypothermia, there is shivering and mental confusion. In moderate hypothermia, shivering stops and confusion increases. In severe hypothermia, there may be hallucinations and paradoxical undressing, in which a person removes their clothing, as well as an increased risk of the heart stopping. Hypothermia has two main types of causes. It classically occurs from exposure to cold weather and cold water immersion. It may also occur from any condition that decreases heat production or increases heat loss. Commonly, this includes alcohol intoxication but may also include low blood sugar, anorexia and advanced age. Body temperature is usually maintained near a constant level of through thermoregulation. Efforts to increase body temperature involve shivering, increased voluntary activity, and putting on warmer clothing. Hypothermia may be diagnosed based on either a ...

Physical Trauma
Injury is physiology, physiological damage to the living tissue of any organism, whether Injury in humans, in humans, Injury in animals, in other animals, or Injury in plants, in plants. Injuries can be caused in many ways, including mechanically with penetrating trauma, penetration by sharp objects such as Tooth, teeth or blunt trauma, with blunt objects, by heat or cold, or by venoms and biotoxins. Injury prompts an Inflammation, inflammatory response in many taxa of animals; this prompts wound healing. In both plants and animals, substances are often released to help to occlude the wound, limiting loss of fluids and the entry of pathogens such as bacteria. Many organisms secrete antimicrobial chemicals which limit wound infection; in addition, animals have a variety of immune responses for the same purpose. Both plants and animals have regrowth mechanisms which may result in complete or partial healing over the injury. Cells too can Cell damage, repair damage to a certain de ...

Suffocation
Asphyxia or asphyxiation is a condition of deficient supply of oxygen to the body which arises from abnormal breathing. Asphyxia causes generalized hypoxia, which affects all the tissues and organs, some more rapidly than others. There are many circumstances that can induce asphyxia, all of which are characterized by the inability of a person to acquire sufficient oxygen through breathing for an extended period of time. Asphyxia can cause coma or death. In 2015, about 9.8 million cases of unintentional suffocation occurred which resulted in 35,600 deaths. The word asphyxia is from Ancient Greek "without" and , "squeeze" (throb of heart). Causes Situations that can cause asphyxia include but are not limited to: airway obstruction (such as from asthma, laryngospasm, or simple blockage from the presence of foreign materials); from being in environments where oxygen is not readily accessible: such as underwater, in a low oxygen atmosphere, or in a vacuum; environments where su ...
