Chainsaw Safety Clothing
Safety practices generally recommend that chainsaw users wear protective clothing, also known as personal protective equipment or PPE, while operating chainsaws. There is general agreement worldwide on what clothing is suitable, but local jurisdictions have specific rules and recommendations. Clothing Helmet The helmet offers some protection for the user's head against impact by the cutter bar of the chainsaw should a 'kickback' occur. Kickback is when the running chainsaw jumps up unexpectedly out of the cut, thus endangering the saw operator. Helmet protection can only be successful if the chain brake has been operated to stop the saw chain, since a chain running at full speed can easily cut into the helmet. The helmet, and its eye protection guard, also protect against impacts from small falling or flying objects, such as dead twigs and branches from a tree being felled. Exposure to the sun causes the plastic of the helmet to weaken over time, so it is recommended that a he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chainsaw Cutting Tree
A chainsaw (or chain saw) is a portable gasoline-, electric-, or battery-powered saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar. It is used in activities such as tree felling, limbing, bucking, pruning, cutting firebreaks in wildland fire suppression, and harvesting of firewood. Chainsaws with specially designed bar-and-chain combinations have been developed as tools for use in chainsaw art and chainsaw mills. Specialized chainsaws are used for cutting concrete during construction developments. Chainsaws are sometimes used for cutting ice; for example, ice sculpture and winter swimming in Finland. History In surgery The origin of chain saws in surgery is debated. A "flexible saw", consisting of a fine serrated link chain held between two wooden handles, was pioneered in the late 18th century (c. 1783–1785) by two Scottish doctors, John Aitken and James Jeffray, for symphysiotomy and excision of diseased bone, respectively.

Recommended Exposure Limit
A recommended exposure limit (REL) is an occupational exposure limit that has been recommended by the United States National Institute for Occupational Safety and Health. The REL is a level that NIOSH believes would be protective of worker safety and health over a working lifetime if used in combination with engineering and work practice controls, exposure and medical monitoring, posting and labeling of hazards, worker training and personal protective equipment. To formulate these recommendations, NIOSH evaluates all known and available medical, biological, engineering, chemical, trade, and other information. Although not legally enforceable limits, RELS are transmitted to the Occupational Safety and Health Administration (OSHA) or the Mine Safety and Health Administration (MSHA) of the U.S. Department of Labor The United States Department of Labor (DOL) is one of the United States federal executive departments, executive departments of the federal government of the United Stat ...

Wellington Boot
The Wellington boot was originally a type of leather boot adapted from Hessian boots, a style of military riding boot. They were worn and popularised by Arthur Wellesley, 1st Duke of Wellington. The "Wellington" boot became a staple of practical foot wear for the British aristocracy and middle class in the early 19th century. The name was subsequently given to waterproof boots made of rubber and they are no longer associated with a particular class. They are now commonly used for a range of agricultural and outdoors pursuits. Design and use Wellington boots in contemporary usage are waterproof and are most often made from rubber or polyvinyl chloride (PVC), a halogenated polymer. They are usually worn when walking on wet or muddy ground, or to protect the wearer from heavy showers and puddles. They are generally just below knee-high although shorter boots are available. The "Wellington" is a common and necessary safety or hygiene shoe in diverse industrial settings: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Thailand, Malaysia, and Indonesia are three of the leading rubber producers. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into the rubber that is ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for sale. Natural rubber is used extensively in many applications and products, either alone or in combination ...

Leather
Leather is a strong, flexible and durable material obtained from the tanning, or chemical treatment, of animal skins and hides to prevent decay. The most common leathers come from cattle, sheep, goats, equine animals, buffalo, pigs and hogs, and aquatic animals such as seals and alligators. Leather can be used to make a variety of items, including clothing, footwear, handbags, furniture, tools and sports equipment, and lasts for decades. Leather making has been practiced for more than 7,000 years and the leading producers of leather today are China and India. Animal rights groups claim that modern commercial leather making and the consumption of its products is unethically killing animals. According to the life-cycle assessment (LCA) report for the United Nations Industrial Development Organization, 99% of the raw hides and skins used in the production of leather derive from animals raised for meat and/or dairy production. Critics of tanneries claim that they engage in u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel-toe Boot
A steel-toe boot (also known as a safety boot, steel-capped boot, steel toecaps or safety shoe) is a durable boot or shoe that has a protective reinforcement in the toe which protects the foot from falling objects or compression. Safety shoes are effective in keeping the feet of industrial workers safe from sharp and heavy objects while working in factories. Although traditionally made of steel, the reinforcement can also be made of a composite material, a plastic such as thermoplastic polyurethane (TPU) or aluminum. Steel-toe boots are important in construction and manufacturing, as well as a variety of other industries. Occupational safety and health legislation or insurance requirements may require the use of such boots in some settings, and may mandate certification of such boots and the display of such certification directly on the boots. The markings on the boot label will indicate the national or international standards that the boot was intended to meet, and identify th ...

Boot
A boot is a type of footwear. Most boots mainly cover the foot and the ankle, while some also cover some part of the lower calf. Some boots extend up the leg, sometimes as far as the knee or even the hip. Most boots have a heel that is clearly distinguishable from the rest of the sole, even if the two are made of one piece. Traditionally made of leather or rubber, modern boots are made from a variety of materials. Boots are worn both for their functionality and for reasons of style and fashion. Functional concerns include: protection of the foot and leg from water, mud, pestilence (infectious disease, insect bites and stings, snake bites), extreme temperatures, sharp or blunt hazards (e.g. work boots may provide steel toes), physical abrasion, corrosive agents, or damaging radiation; ankle support and traction for strenuous activities such as hiking; and durability in harsh conditions (e.g. the underside of combat boots may be reinforced with hobnails). In some ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gloves
A glove is a garment covering the hand. Gloves usually have separate sheaths or openings for each finger and the thumb. If there is an opening but no (or a short) covering sheath for each finger they are called fingerless gloves. Fingerless gloves having one small opening rather than individual openings for each finger are sometimes called gauntlets, though gauntlets are not necessarily fingerless. Gloves which cover the entire hand or fist but do not have separate finger openings or sheaths are called mittens. Mittens are warmer than other styles of gloves made of the same material because fingers maintain their warmth better when they are in contact with each other; reduced surface area reduces heat loss. A hybrid of glove and mitten contains open-ended sheaths for the four fingers (as in a fingerless glove, but not the thumb) and an additional compartment encapsulating the four fingers. This compartment can be lifted off the fingers and folded back to allow the individual f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kevlar
Kevlar (para-aramid) is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires. It is typically spun into ropes or fabric sheets that can be used as such, or as an ingredient in composite material components. Kevlar has many applications, ranging from bicycle tires and racing sails to bulletproof vests, all due to its high tensile strength-to-weight ratio; by this measure it is five times stronger than steel. It is also used to make modern marching drumheads that withstand high impact; and for mooring lines and other underwater applications. A similar fiber called Twaron with the same chemical structure was developed by Akzo in the 1970s; commercial production started in 1986, and Twaron is now manufactured by Teijin.

Ballistic Nylon
Ballistic nylon is a thick, tough, nylon fabric with several uses. Ballistic nylon was developed by the DuPont corporation as a material for flak jackets to be worn by World War II airmen. The term ''ballistic nylon'' originates in the fabric's intended function, protecting its wearers from flying debris and fragmentation caused by bullet and artillery-shell impacts. Description The original specification for ballistic nylon was an 18 ounce nylon fabric made from 1050 denier high tenacity nylon yarn in a 2×2 basketweave. Today the term is often used to refer to any nylon fabric that is made with a "ballistic weave", typically a 2×2 or 2×3 basketweave. It can be woven from nylon yarns of various denier such as 840 denier and 1680 denier. Origin Ballistic nylon was originally developed by the Dupont corporation for flak jackets for World War II airmen. The name of this nylon speaks to its origin; its intent was to protect the airmen from flying debris and fragmentatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaps
Chaps ( or ) are sturdy coverings for the legs consisting of leggings and a belt. They are buckled on over trousers with the chaps' integrated belt, but unlike trousers, they have no seat (the term "assless chaps" is a tautology) and are not joined at the crotch. They are designed to provide protection for the legs and are usually made of leather or a leather-like material. Their name is a shortened version of the Spanish word ''chaparajos''. ''Chaparajos'' were named after the chaparral (thick, thorny, low brush) from which they were designed to protect the legs while riding on horseback. Like much of western American horse culture, the origin of ''chaparajos'' was in the south of Spain, from which it then passed on to the part of New Spain that later became Mexico, and has been assimilated into cowboy culture of the American west. They are a protective garment to be used when riding a horse through brushy terrain. In the modern world, they are worn for both practical work pur ...
