Lanyard
A lanyard is a cord, length of webbing, or strap that may serve any of various functions, which include a means of attachment, restraint, retrieval, and activation and deactivation. A lanyard is also a piece of rigging used to secure or lower objects aboard a ship."lanyard lan-yrd." Merriam-Webster's Collegiate(R) Dictionary. Springfield: Merriam-Webster, 2004. Credo Reference. Web. 1 October 2012. Origins The earliest references to lanyards date from 15th century France: "lanière" was a thong or strap-on apparatus. Bosun's pipe, marlinspike, and small knives typically had a lanyard consisting of a string loop tied together with a diamond knot. It helped secure against fall and gave an extended grip over a small handle. In the French military, lanyards were used to connect a pistol, sword, or whistle (for signaling) to a uniform semi-permanently. Lanyards were used by mounted cavalry on land and naval officers at sea. A pistol lanyard can be easily removed and reattach ...

Diamond Knot
The diamond knot (or knife lanyard knot) is a knot for forming a decorative loop on the end of a cord such as on a lanyard. A similar knot, also called the diamond knot, is a multistrand stopper knot, that is similar in appearance (although the footrope knot is really more similar, but it is simply an upside down diamond knot). To avoid confusion, it is advisable to call this knot the knife lanyard knot. This knot is a four strand diamond knot implemented in two strands. The knife lanyard knot is "tied alike" the Chinese button knot, "but they are worked differently."Ashley (1944), p.101. Tying The diamond knot begins as a Carrick bend with the ends exiting diagonally opposite each other. When the steps below are completed the knot is rearranged and tightened so that the ends emerge from the knot parallel and opposite their own standing part. A Chinese button knot is often tied in a very similar manner, but without leaving a loop at the end. Image:Knife-lanyard-knot-ABOK-7 ...

Safety Lanyard
Fall arrest is the form of fall protection which involves the safe stopping of a person already falling. It is one of several forms of fall protection, forms which also include fall guarding (general protection that prevents persons from entering a fall hazard area e.g., guard rails) and fall restraint (personal protection which prevents persons who are in a fall hazard area from falling in the first place, e.g., fall restraint lanyards). The U.S. Department of Labor's Occupational Safety and Health Administration specifies under Title 29 of the Code of Federal Regulations that individuals working at height must be protected from fall injury, and fall arrest is one of several forms of fall protection as defined within that Code. Personal fall arrest systems Fall arrest is of two major types: general fall arrest, such as nets; and personal fall arrest, such as lifelines. The most common manifestation of fall arrest in the workplace is the Personal Fall Arrest System, or PFAS ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tether
A tether is a cord, fixture, or flexible attachment that characteristically anchors something movable to something fixed; it also maybe used to connect two movable objects, such as an item being towed by its tow. Applications for tethers include: fall arrest systems, lanyards, balloons, kites, airborne wind-power systems, anchors, floating water power systems, towing, animal constraint, space walks, power kiteing, and anti-theft devices. Failure Failure modes for tethers are considered in their design. A cord or rope tether may reach its breaking strength and fail. Outcomes can include an injury or fatal fall, and damage or loss of life to personnel or bystanders caused by backlash of the ruptured segments. Failure-prevention may be designed into a tethering system. Some safety harnesses are used in combination with a shock-absorbing lanyard, which has break-away stitching designed into it to prevent material failure and regulate deceleration, thereby preventing a serious ...

Safety Harness
A safety harness is a form of protective equipment Personal protective equipment (PPE) is protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, ele ... designed to safeguard the user from injury or death from falling. The core item of a fall arrest system, the harness is usually fabricated from rope, Wire rope, braided wire cable, or webbing, synthetic webbing. It is attached securely to a stationary object directly by a carabiner, locking device or indirectly via a rope, cable, or webbing and one or more locking devices. Some safety harnesses are used in combination with a shock absorber, shock-absorbing lanyard, which is used to regulate deceleration and thereby prevent a serious G-force injury when the end of the rope is reached. An unrelated use with a materially different arresting mechanism is bungee jumping. Though they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knife
A knife ( : knives; from Old Norse 'knife, dirk') is a tool or weapon with a cutting edge or blade, usually attached to a handle or hilt. One of the earliest tools used by humanity, knives appeared at least 2.5 million years ago, as evidenced by the Oldowan tools. Originally made of wood, bone, and stone (such as flint and obsidian), over the centuries, in step with improvements in both metallurgy and manufacturing, knife blades have been made from copper, bronze, iron, steel, ceramic, and titanium. Most modern knives have either fixed or folding blades; blade patterns and styles vary by maker and country of origin. Knives can serve various purposes. Hunters use a hunting knife, soldiers use the combat knife, scouts, campers, and hikers carry a pocket knife; there are kitchen knives for preparing foods (the chef's knife, the paring knife, bread knife, cleaver), table knives (butter knives and steak knives), weapons (daggers or switchblades), knives for throwing or juggling, a ...

Rigging
Rigging comprises the system of ropes, cables and chains, which support a sailing ship or sail boat's masts—''standing rigging'', including shrouds and stays—and which adjust the position of the vessel's sails and spars to which they are attached—the ''running rigging'', including halyards, braces, sheets and vangs. Etymology According to the Encyclopædia Britannica Eleventh Edition "rigging" derives from Anglo-Saxon ''wrigan'' or ''wringing'', "to clothe". The same source points out that "rigging" a sailing vessel refers to putting all the components in place to allow it to function, including the masts, spars, sails and the rigging. Types of rigging Rigging is divided into two classes, ''standing'', which supports the mast (and bowsprit), and ''running'', which controls the orientation of the sails and their degree of reefing. Configurations differ for each type of rigging, between ''fore-and-aft rigged'' vessels and ''square-rigged'' vessels. Standing Standin ...

Dead Man’s Switch
A dead man's switch (see alternative names) is a switch that is designed to be activated or deactivated if the human operator becomes incapacitated, such as through death, loss of consciousness, or being bodily removed from control. Originally applied to switches on a vehicle or machine, it has since come to be used to describe other intangible uses, as in computer software. These switches are usually used as a form of fail-safe where they stop a machine with no operator from a potentially dangerous action or incapacitate a device as a result of accident, malfunction, or misuse. They are common in such applications in locomotives, aircraft refuelling, freight elevators, lawn mowers, tractors, personal watercraft, outboard motors, chainsaws, snowblowers, tread machines, snowmobiles, amusement rides, and many medical imaging devices. On some machines, these switches merely bring the machines back to a safe state, such as reducing the throttle to idle or applying brakes while leav ...

Marlingspike
A marlinspike (, sometimes spelled marlin spike, marlinespike, or rchaicmarlingspike) is a tool used in marine ropework. Shaped in the form of a polished metal cone tapered to a rounded or flattened point, it is used in such tasks as unlaying rope for splicing, untying knots, drawing marline tight using a marlinspike hitch, and as a toggle joining ropes under tension in a belaying pin splice. Marlinspikes are usually about long, but may reach or more when used for working heavy cables and ropes. They are usually made from iron or steel, whereas fids, similar in shape and function, are formed from wood or bone. The marlinspike may be a separate tool or one item on a pocket knife. Sailors who become proficient at knot tying, splicing, and sewing using the marlinspike are said to have mastered marlinespike seamanship, earning them the right to be known as ''marlin spikes'' or ''marlinspike seamen''. Uses Marlinspikes are used: * As levers to open strands of laid rope w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuze
In military munitions, a fuze (sometimes fuse) is the part of the device that initiates function. In some applications, such as torpedoes, a fuze may be identified by function as the exploder. The relative complexity of even the earliest fuze designs can be seen in cutaway diagrams. A fuze is a device that detonates a munition's explosive material under specified conditions. In addition, a fuze will have safety and arming mechanisms that protect users from premature or accidental detonation. For example, an artillery fuze's battery is activated by the high acceleration of cannon launch, and the fuze must be spinning rapidly before it will function. "Complete bore safety" can be achieved with mechanical shutters that isolate the detonator from the main charge until the shell is fired. A fuze may contain only the electronic or mechanical elements necessary to signal or actuate the detonator, but some fuzes contain a small amount of primary explosive to initiate the detonation. ...

Identification Card
An identity document (also called ID or colloquially as papers) is any document that may be used to prove a person's identity. If issued in a small, standard credit card size form, it is usually called an identity card (IC, ID card, citizen card), or passport card. Some countries issue formal identity documents, as national identification cards that may be compulsory or non-compulsory, while others may require identity verification using regional identification or informal documents. When the identity document incorporates a person's photograph, it may be called photo ID. In the absence of a formal identity document, a driver's license may be accepted in many countries for identity verification. Some countries do not accept driver's licenses for identification, often because in those countries they do not expire as documents and can be old or easily forged. Most countries accept passports as a form of identification. Some countries require all people to have an identity docu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
