A rescue toboggan, also known as a rescue sled [1] or emergency rescue sledge, [2] or by the Finnish word ahkio (also transliterated akia, ackja, akija, and akja), [3] is a carrier for transporting a person or goods on snowy or icy surfaces. It is used by mountain rescue or ski patrol teams to evacuate an injured skier or snowboarder. There are related designs for use on water to carry accident victims or emergency equipment.
A rescue toboggan takes the form of a pulk or small sled shaped as an elongated boat-like pan, usually made of aluminum or fiberglass, [4] with vaulted ends, each of which may be attached to forked extending handles. There are many variations and adaptations such as a brake, stability fins, [5] and an integrated or removable litter. A particular variation may be preferred by various regions or individual ski patrollers.
The trough has a trapezoidal cross section and the edges of the lower surfaces have three central stiffening skids. The straight bars, often made of steel pipe, lower the contour of the lower space and end with large oval rings about twice hip width.
The toboggan is directionally symmetrical so it can move either head first or foot first. When empty or with a light load, it can be handled by one person alone. With a full load or a well secured person in it, it requires two rescuers on skis who can take much of the weight of the load off the snow through two sets of handles to prevent passenger impacts from bumps for a smoother and safer ride with better control from four ski edges.
A brake chain under the downhill end controls speed in steep terrain when pressure is applied to the front spars which proportionally affects the location and length of the chain to regulate the braking effect. A line attached to the toboggan secures it to a rescuer.
There are one and two piece toboggans. The latter is divisible so it can be carried on a backpack. The bars can be removed to carry the basket in a vehicle or on ski lifts and snowcats.
Previous models were made of wood.
After first aid or other initial medical treatment, the patient is placed in the toboggan wrapped in a vacuum mattress or insulating pads, and wrapped with a windproof blanket. Heat reflective emergency blankets reflect thermal radiation and heating packs, hot water bottles, or electric blankets might be used to warm the patient.
If the patient has injuries to the lower extremities and must be transported over longer steep distances, they are additionally held in a rescue seat and drawn up to relieve the legs and protect them from body weight.
After securing the injured person, she is transported to a point where evacuation by vehicle can occur. The rescue toboggan and patient can be carried by ambulance on roads or by a rescue helicopter.
In summer, toboggans can be used as an alternative to stretchers when on rough terrain. For longer distances on trails or other grounds, a centrally-placed wheeled axle carries a large proportion of the patient's weight.
Akias were used by Finnish military at least from the 1930s, after that being adopted by ski patrollers and rescuers around the world, such as Mount Hood Ski Patrol to replace dogsleds. [6]
A luge is a small one- or two-person sled on which one sleds supine (face-up) and feet-first. A luger begins seated, propelling themselves initially from handles on either side of the start ramp, then steers by using the calf muscles to flex the sled's runners or by exerting opposite shoulder pressure to the pod. Racing sleds weigh 21–25 kg (46–55 lb) for singles and 25–30 kg (55–66 lb) for doubles. Luge is also the name of an Olympic sport that employs that sled and technique.
A sled, skid, sledge, or sleigh is a land vehicle that slides across a surface, usually of ice or snow. It is built with either a smooth underside or a separate body supported by two or more smooth, relatively narrow, longitudinal runners similar in principle to skis. This reduces the amount of friction, which helps to carry heavy loads.
An elevated passenger ropeway, or chairlift, is a type of aerial lift, which consists of a continuously circulating steel wire rope loop strung between two end terminals and usually over intermediate towers, carrying a series of chairs. They are the primary on-hill transport at most ski areas, but are also found at amusement parks and various tourist attractions.
A snowmobile, also known as a snowmachine, motor sled, motor sledge, skimobile, or snow scooter, is a motorized vehicle designed for winter travel and recreation on snow.
Rope rescue is a subset of technical rescue that involves the use of rope, be it steel or cable rope, or more commonly used nylon, polyester, or other type of rope. Kernmantle rope as it is called, is available in various types: dynamic or static which is most commonly used in rescue and industrial rope work. Anchoring includes using specialty anchors, as well as things as simple as a length of chain, cable, rope, or webbing wrapped around a pillar, tree, boulder, or such. They provide the security and a point from which a person or subject can be belayed. Belaying is the act of protecting the climber, rescue professional, or subject in the event of a fall. Various other devices used, including friction rappel (lowering) devices, which acts as a braking device on the rope. They are used for lowering a load, a subject or oneself (rappelling). Pulleys can serve as a mechanical advantage, along with rope grabs, and other tools, to raise, or haul, a load up a vertical section, or across a gully or canyon. Pulleys systems are used in conjunction with the rope, rope grabbing devices, i.e.: Prusiks, or mechanical grabs, to capture the progress made during the lift. Since pulley systems are generally short in length, they are used in conjunction with a progress (raise) capturing technique, and a long rope; and a backup safety or belay. This specialized equipment is used to reach the subject(s) and safely recover them.
Sledding, sledging or sleighing is a winter sport typically carried out in a prone or seated position on a vehicle generically known as a sled, a sledge (British), or a sleigh. It is the basis of three Olympic sports: luge, skeleton and bobsledding. When practised on sand, it is known as a form of sandboarding. In Russia sledges are used for maritime activities including fishing and commuting from island to island on ice.
A stretcher, gurney, litter, or pram is an apparatus used for moving patients who require medical care. A basic type must be carried by two or more people. A wheeled stretcher is often equipped with variable height frames, wheels, tracks, or skids.
On trains, the expression emergency brake has several meanings:
A toboggan is a simple sled traditionally used by children. It is also a traditional form of transport used by the Innu and Cree of northern Canada.
Automobile handling and vehicle handling are descriptions of the way a wheeled vehicle responds and reacts to the inputs of a driver, as well as how it moves along a track or road. It is commonly judged by how a vehicle performs particularly during cornering, acceleration, and braking as well as on the vehicle's directional stability when moving in steady state condition.
Mushing is a sport or transport method powered by dogs. It includes carting, pulka, dog scootering, sled dog racing, skijoring, freighting, and weight pulling. More specifically, it implies the use of one or more dogs to pull a sled, most commonly a specialized type of dog sled on snow, or a rig on dry land.
A spinal board, is a patient handling device used primarily in pre-hospital trauma care. It is designed to provide rigid support during movement of a person with suspected spinal or limb injuries. They are most commonly used by ambulance staff, as well as lifeguards and ski patrollers. Historically, backboards were also used in an attempt to "improve the posture" of young people, especially girls.
Ski patrols are organizations that provide medical, rescue, and hazard prevention services to the injured in ski area boundaries, or sometimes beyond into backcountry settings. Many have technical-medical certifications, such as Outdoor Emergency Care (OEC) provided by the National Ski Patrol (USA), that are specific to the winter-season environment and providing emergency medical services in remote locations. Many patrollers also hold EMS issued credentials, such as emergency medical technician or any other pre-hospital care certification. Due to the remote location and terrain, transportation is often limited to Rescue toboggan, snowmobile, or, for life-compromising injuries or extremely remote terrain, helicopter rescue. Depending on the ski area terrain, ski patrollers can be versed in a large variety of specialized rescues, such as avalanche search and rescue, outdoor emergency transportation, chairlift evacuation, and, in some cases, helicopter rescue techniques are taught. Patrols work to promote ski safety, enforce area policies, and help the injured within their jurisdiction. Ski patrollers also work to set up the mountain before it opens by conducting trail checks, providing avalanche control work, and setting up necessary equipment in preparation for the day. At the end of the day, they also conduct a sweep clearing the mountain for off-hours.
The nonprofit National Ski Patrol (NSP) is the largest winter education organization in the world. The NSP provides education, outreach, and credentialing related to outdoor recreation and safety. It is currently composed of more than 31,000 members who serve in over 650 patrols. NSP members, both volunteer and paid, ensure the safety of outdoor recreation enthusiasts in ski areas throughout the United States of America and certain military areas of Europe. For its dedication to the promotion of public safety in skiing and other winter sports, the group was granted a congressional charter under Title 36 of the United States Code in 1980.
A Prusik is a friction hitch or knot used to attach a loop of cord around a rope, applied in climbing, canyoneering, mountaineering, caving, rope rescue, ziplining, and by arborists. The term Prusik is a name for both the loops of cord used to tie the hitch and the hitch itself, and the verb is "to prusik" or "prusiking". More casually, the term is used for any friction hitch or device that can grab a rope. Due to the pronunciation, the word is often misspelled Prussik, Prussick, or Prussic.
A litter is a stretcher designed to be used where there are physical obstacles that impair movement, including other hazards such as, in confined spaces, on slopes or uneven terrain, or in densely forested areas. Typically it is shaped to accommodate an adult in a face up position and it is used in search and rescue operations. The person is strapped into the basket, making safe evacuation possible. The person generally is further protected by a cervical collar and sometimes a long spine board, so as to immobilize the person and prevent further injury.
Mount Hood is an 18-hole golf club and park located in Melrose, Massachusetts. It was built in the 1930s on donated land as part of President Franklin D. Roosevelt's Works Progress Administration and once consisted of a ski area. Today, Mount Hood serves as a golf course and park, while sledding is popular in the winter.
A specialized set of jargon describe the tools, equipment, and employment sectors used in the trucking industry in the United States. Some terms may be used within other English-speaking countries, or within the freight industry in general. For example, shore power is a term borrowed from shipping terminology, in which electrical power is transferred from shore to ship, instead of the ship relying upon idling its engines. Drawing power from land lines is more efficient than engine idling and eliminates localized air pollution. Another borrowed term is "landing gear", which refers to the legs which support the front end of a semi-trailer when it is not connected to a semi-truck. Some nicknames are obvious wordplay, such as "portable parking lot", in reference to a truck that carries automobiles.
A summer toboggan is an amusement or recreational ride which uses a bobsled-like sled or cart to run down a track usually built on the side of a hill. There are two main types: an alpine coaster or mountain coaster is a type of roller coaster where the cart runs on rails and is not able to leave the track, whereas with an alpine slide the cart simply runs on a smooth concave track usually made of metal, concrete or fiberglass. Both of these types of ride are sometimes denoted with the German name sommerrodelbahn.
ISO 7010 is an International Organization for Standardization technical standard for graphical hazard symbols on hazard and safety signs, including those indicating emergency exits. It uses colours and principles set out in ISO 3864 for these symbols, and is intended to provide "safety information that relies as little as possible on the use of words to achieve understanding."
Bennett said much of the time involved in developing his sled was focused on constructing a fin system to keep the sled behind the operator, as opposed to sliding away down the hill.
"I took some garbage to the dump one day, saw a box spring frame, and thought, 'That would make a perfect fin,'" he said. "The first design was just one long fin in the middle at the back of the sled. It didn't work. Then I cut that fin in two and put one piece on either side at the back of the sled. That worked great."
Another problem Bennett overcame was how to engineer an effective braking system. He said he was testing his design one day when it suddenly started to pick up speed at an alarming rate before he managed to regain control.
"You better believe I was thinking the whole time about what I could come up with to slow the thing down!" he said.
Bennett's solution was to install a chain under the sled's nose that contacts the snow only when the operator pushes down on the poles used to pull the sled. The resulting friction stops the sled.
Several patrollers saw an old European mountain rescue film showing an akja, a boat like sled with handles fore and aft, used in mountain rescue work in Bavaria . In 1958, the patrol borrowed an akja from a climbing group and modified the handles for patrol work.
