Jump to navigation Jump to search Practicing with a survival suit An immersion suit, or survival suit (or more specifically an immersion survival suit) is a special type of waterproof dry suit that protects the wearer from hypothermia from immersion in cold water, after abandoning a sinking or capsized vessel, especially in the open ocean. They usually have built-in feet (boots), and a hood, and either built-in gloves or watertight wrist seals. The first record of a survival suit was in 1930 when a New York firm American Life Suit Corporation offered merchant and fishing firms what it called a safety suit for crews of ocean vessels. The suit came packed in a small box and was put on like a boilersuit. The ancestor of these suits was already invented in 1872 by Clark S Merriman to rescue steamship passengers. It was made from rubber sheeting and became famous by the swim records of Paul Boyton. It was essentially a pair of rubber pants and shirt cinched tight at the waist with a steel band and strap. Within the suit were five air pockets the wearer could inflate by mouth through hoses. Similar to modern-day drysuits, the suit also kept its wearer dry. This essentially allowed him to float on his back, using a double-sided paddle to propel himself, feet-forward. Additionally he could attach a small sail to save stamina while slowly drifting to shore (because neither emergency radio transmitters nor rescue helicopters were invented yet). The first immersion suit to gain USCG approval was invented by Gunnar Guddal. Eventually the suit became accepted as essential safety gear. These suits are in two types: This type is chosen to fit each wearer. They are often worn by deep-sea fishermen who work in cold water fishing grounds. Some of these garments overlap into scubadiver-type drysuits. Others may have many of the features of a survival suit. Since humans are warm blooded and sweat to cool themselves, suits that are worn all the time usually have some method for sweat to evaporate and the wearer to remain dry while working. The first survival suits in Europe were invented by Daniel Rigolet, captain of a French oil tanker. Others had experimented on similar suits abroad. Unlike work suits, "quick don" survival suits are not normally worn, but are stowed in an accessible location on board the craft. The operator may be required to have one survival suit of the appropriate size on board for each crew member, and other passengers. If a survival suit is not accessible both from a crew member's work station and berth, then two accessible suits must be provided. This type of survival suit's flotation and thermal protection is usually better than an immersion protection work suit, and typically extends a person's survival by several hours while waiting for rescue. An adult survival suit is often a large bulky one-size-fits-all design meant to fit a wide range of sizes. It typically has large oversize booties and gloves built into the suit, which let the user quickly don it on while fully clothed, and without having to remove shoes. It typically has a waterproof zipper up the front, and a face flap to seal water out around the neck and protect the wearer from ocean spray. Because of the oversized booties and large mittens, quick don survival suits are often known as "Gumby suits," after the 1960s-era children's toy. The integral gloves may be a thin waterproof non-insulated type to give the user greater dexterity during donning and evacuation, with a second insulating outer glove tethered to the sleeves to be worn while immersed. A ship's captain (or master) may be required to hold drills periodically to ensure that everyone can get to the survival suit storage quickly, and don the suit in the allotted amount of time. In the event of an emergency, it should be possible to put on a survival suit and abandon ship in about one minute. The Submarine Escape Immersion Equipment is a type of survival suit that can be used by sailors when escaping from a sunken submarine. The suit is donned before escaping from the submarine and then inflated to act as a liferaft when the sailor reaches the surface. Survival suits are normally made out of red or bright fluorescent orange or yellow fire-retardant neoprene, for high visibility on the open sea. The neoprene material used is a synthetic rubber closed-cell foam, containing a multitude of tiny air bubbles making the suit sufficiently buoyant to also be a personal flotation device. The seams of the neoprene suit are sewn and taped to seal out the cold ocean water, and the suit also has strips of SOLAS specified retroreflective tape on the arms, legs, and head to permit the wearer to be located at night from a rescue aircraft or ship. The method of water sealing around the face can affect wearer comfort. Low-cost quick-donning suits typically have an open neck from chest to chin, closed by a waterproof zipper. However the zipper is stiff and tightly compresses around the face resulting in an uncomfortable fit intended for short-duration use until the wearer can be rescued. The suit material is typically very rigid and the wearer is unable to look to the sides easily. Suits intended for long-term worksuit use, or donned by rescue personnel, typically have a form-fitting neck-encircling seal, with a hood that conforms to the shape of the chin. This design is both more comfortable and allows the wearer to easily turn their head and look up or down. The suit material is designed to be either loose or elastic enough to allow the wearer to pull the top of the suit up over their head and then down around their neck. Survival suits can also be equipped with extra safety options such as: The inflatable survival suit is a special type of survival suit, recently developed, which is similar in construction to an inflatable boat, but shaped to wrap around the arms and legs of the wearer. This type of suit is much more compact than a neoprene survival suit, and very easy to put on when deflated since it is just welded from plastic sheeting to form an air bladder. Once the inflatable survival suit has been put on and zipped shut, the wearer activates firing handles on compressed carbon dioxide cartridges, which punctures the cartridges and rapidly inflates the suit. This results in a highly buoyant, rigid shape that also offers very high thermal retention properties. However, like an inflatable boat, the inflatable survival suit loses all protection properties if it is punctured and the gas leaks out. For this reason, the suit may consist of two or more bladders, so that if one fails, a backup air bladder is available. Each immersion suit needs to be regularly checked and maintained properly in order to be ready for use all the time. The maintenance of the immersion suits kept on board of the vessels must be done according to the rules of the International Maritime Organization (IMO). There are two Guidelines issued by IMO - MSC/Circ.1047  and MSC/Circ.1114  in relation to immersion suits’ maintenance. The first one gives instruction for monthly inspection and maintenance which must be done by the ship’s crew. The second one is concerning pressure testing which can be done only with special equipment. Usually it is done ashore by specialized companies but can be done also onboard of the vessels if practical. It must be performed every three years for immersion suits less than 12 years old and every second year on older ones. The years are counted from the suit’s date of manufacture.

Main article: Wilderness medical emergency A first aid kit containing equipment to treat common injuries and illness First aid (wilderness first aid in particular) can help a person survive and function with injuries and illnesses that would otherwise kill or incapacitate him/her. Common and dangerous injuries include: The survivor may need to apply the contents of a first aid kit or, if possessing the required knowledge, naturally occurring medicinal plants, immobilize injured limbs, or even transport incapacitated comrades. Main article: Bivouac shelter Shelter built from tarp and sticks. Pictured are displaced persons from the Sri Lankan Civil War A shelter can range from a natural shelter, such as a cave, overhanging rock outcrop, or fallen-down tree, to an intermediate form of man-made shelter such as a debris hut, tree pit shelter, or snow cave, to completely man-made structures such as a tarp, tent, or longhouse. Making fire is recognized in the sources as significantly increasing the ability to survive physically and mentally. Lighting a fire without a lighter or matches, e.g. by using natural flint and steel with tinder, is a frequent subject of both books on survival and in survival courses. There is an emphasis placed on practicing fire-making skills before venturing into the wilderness. Producing fire under adverse conditions has been made much easier by the introduction of tools such as the solar spark lighter and the fire piston. To start a fire you’ll need some sort of heat source hot enough to start a fire, kindling, and wood. Starting a fire is really all about growing a flame without putting it out in the process. One fire starting technique involves using a black powder firearm if one is available. Proper gun safety should be used with this technique to avoid injury or death. The technique includes ramming cotton cloth or wadding down the barrel of the firearm until the cloth is against the powder charge. Next, fire the gun up in a safe direction, run and pick up the cloth that is projected out of the barrel, and then blow it into flame. It works better if you have a supply of tinder at hand so that the cloth can be placed against it to start the fire. Fire is presented as a tool meeting many survival needs. The heat provided by a fire warms the body, dries wet clothes, disinfects water, and cooks food. Not to be overlooked is the psychological boost and the sense of safety and protection it gives. In the wild, fire can provide a sensation of home, a focal point, in addition to being an essential energy source. Fire may deter wild animals from interfering with a survivor, however wild animals may be attracted to the light and heat of a fire. Hydration pack manufactured by Camelbak A human being can survive an average of three to five days without the intake of water. The issues presented by the need for water dictate that unnecessary water loss by perspiration be avoided in survival situations. The need for water increases with exercise. A typical person will lose minimally two to maximally four liters of water per day under ordinary conditions, and more in hot, dry, or cold weather. Four to six liters of water or other liquids are generally required each day in the wilderness to avoid dehydration and to keep the body functioning properly. The U.S. Army survival manual does not recommend drinking water only when thirsty, as this leads to underhydrating. Instead, water should be drunk at regular intervals. Other groups recommend rationing water through "water discipline". A lack of water causes dehydration, which may result in lethargy, headaches, dizziness, confusion, and eventually death. Even mild dehydration reduces endurance and impairs concentration, which is dangerous in a survival situation where clear thinking is essential. Dark yellow or brown urine is a diagnostic indicator of dehydration. To avoid dehydration, a high priority is typically assigned to locating a supply of drinking water and making provision to render that water as safe as possible. Recent thinking is that boiling or commercial filters are significantly safer than use of chemicals, with the exception of chlorine dioxide. Culinary root tubers, fruit, edible mushrooms, edible nuts, edible beans, edible cereals or edible leaves, edible moss, edible cacti and algae can be gathered and if needed, prepared (mostly by boiling). With the exception of leaves, these foods are relatively high in calories, providing some energy to the body. Plants are some of the easiest food sources to find in the jungle, forest or desert because they are stationary and can thus be had without exerting much effort. Skills and equipment (such as bows, snares and nets) are necessary to gather animal food in the wild include animal trapping, hunting, and fishing. Food, when cooked in canned packaging (e.g. baked beans) may leach chemicals from their linings . Focusing on survival until rescued by presumed searchers, the Boy Scouts of America especially discourages foraging for wild foods on the grounds that the knowledge and skills needed are unlikely to be possessed by those finding themselves in a wilderness survival situation, making the risks (including use of energy) outweigh the benefits. Cockroaches, flies and ants can contaminate food, making it unsafe for consumption. Celestial navigation: using the Southern Cross to navigate South without a compass Those going for trips and hikes are advised by Search and Rescue Services to notify a trusted contact of their planned return time, then notify them of your return. They can tell them to contact the police for search and rescue if you have not returned by a specific time frame (e.g. 12 hours of your scheduled return time). Survival situations can often be resolved by finding a way to safety, or a more suitable location to wait for rescue. Types of navigation include: The mind and its processes are critical to survival. The will to live in a life-and-death situation often separates those that live and those that do not. Stories of heroic feats of survival by regular people with little or no training but a strong will to live are not uncommon. Among them is Juliane Koepcke, who was the sole survivor among the 93 passengers when her plane crashed in the jungle of Peru. Situations can be stressful to the level that even trained experts may be mentally affected. One should be mentally and physically tough during a disaster. To the extent that stress results from testing human limits, the benefits of learning to function under stress and determining those limits may outweigh the downside of stress. There are certain strategies and mental tools that can help people cope better in a survival situation, including focusing on manageable tasks, having a Plan B available and recognizing denial. In a building collapse, it is advised that you: Civilian pilots attending a Survival course at RAF Kinloss learn how to construct shelter from the elements, using materials available in the woodland on the north-east edge of the aerodrome. Main article: Survival kit Often survival practitioners will carry with them a "survival kit". This consists of various items that seem necessary or useful for potential survival situations, depending on anticipated challenges and location. Supplies in a survival kit vary greatly by anticipated needs. For wilderness survival, they often contain items like a knife, water container, fire starting apparatus, first aid equipment, food obtaining devices (snare wire, fish hooks, firearms, or other,) a light, navigational aids, and signalling or communications devices. Often these items will have multiple possible uses as space and weight are often at a premium. Survival kits may be purchased from various retailers or individual components may be bought and assembled into a kit. Some survival books promote the "Universal Edibility Test". Allegedly, it is possible to distinguish edible foods from toxic ones by a series of progressive exposures to skin and mouth prior to ingestion, with waiting periods and checks for symptoms. However, many experts including Ray Mears and John Kallas reject this method, stating that even a small amount of some "potential foods" can cause physical discomfort, illness, or death. Many mainstream survival experts have recommended the act of drinking urine in times of dehydration and malnutrition. However, the United States Air Force Survival Manual (AF 64-4) instructs that this technique is a myth and should never be applied. Several reasons for not drinking urine include the high salt content of urine, potential contaminants, and sometimes bacteria growth, despite urine's being generally "sterile". Many classic cowboy movies, classic survival books and even some school textbooks suggest that sucking the venom out of a snake bite by mouth is an appropriate treatment and/or also for the bitten person to drink their urine after the poisonous animal bite or poisonous insect bite as a mean for the body to provide natural anti-venom. However, venom can not be sucked out and it may be dangerous for a rescuer to attempt to do so. Modern snakebite treatment involves pressure bandages and prompt medical treatment. Media
