Lanyard

Lanyard is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lanyard rather than just read about it. In short: A lanyard is a length of cord, webbing, or strap used for attachment, carrying, restraint, retrieval, activation, or deactivation. Lanyards range from light-duty straps worn around the neck, shoulder, wrist, or belt for carrying items such as keys, identification cards or badges, and small electronic devices, to safety equipment used for fall restraint, confined-space retrieval, and dead man's switches.

Key takeaways

  • Lanyard belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Lanyard to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Lanyard from memory before moving on to harder problems.

Reference excerpt

A lanyard is a length of cord, webbing, or strap used for attachment, carrying, restraint, retrieval, activation, or deactivation. Lanyards range from light-duty straps worn around the neck, shoulder, wrist, or belt for carrying items such as keys, identification cards or badges, and small electronic devices, to safety equipment used for fall restraint, confined-space retrieval, and dead man's switches. Historically, lanyards have been used to secure equipment such as weapons, whistles, marlinspikes, and knives. They are also worn on some military uniforms as decorative or identifying cords denoting qualifications or regimental affiliations. Modern lanyards are made from polyester, nylon, silk, leather, paracord, polyethylene terephthalate (PET), and other materials.

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 the item 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 reattached by the user, but will stay connected to the pistol whether it is drawn for use or it is placed into a holster for carrying. In the military, lanyards of various colour combinations and braid patterns are worn on the shoulders of uniforms to denote the wearer's qualification or regimental affiliation. In horse regiments, lanyards were worn on the left, enabling a rider to pull a whistle from the left tunic pocket and maintain communication with his troop. Members of the British Royal Artillery wear a lanyard which originally held a key for adjusting the fuzes of explosive shells.

Functions An attachment lanyard is a light duty tether worn around the neck, shoulder, wrist or attached to the belt as a sling to conveniently carry items such as keys or identification cards, or as a safety harness to prevent accidental dropping of valuable handheld items such as a camera. A restraint lanyard is a safety lanyard used by construction workers, such as a lineman. A retrieval lanyard is a nylon webbing lanyard used to raise and lower workers into confined spaces, such as storage tanks. An activation lanyard is a lanyard used to fire an artillery piece or arm the fuze on a bomb leaving an aircraft. A deactivation lanyard is a dead man's switch, where pulling a lanyard free will disable a dangerous device.

Styles and materials

The style, design or material used will vary depending on end-purpose of the lanyard. Lanyard materials include polyester, nylon, satin, silk, polyethylene terephthalate (PET), braided leather or braided paracord.

Common styles Polyester imprinted lanyards Nylon imprinted lanyards Tube imprinted lanyards Dye-sublimated lanyards or full-color lanyards

Accessory for electronics

Lanyards are widely used with small electronic devices such as cameras, MP3 players and USB flash drives to prevent loss or dropping. Electronics designed to take a lanyard usually have a small through-hole built into a corner or edge of the case or anchored to the frame of the device; the corresponding lanyard generally has a loop of thread on the end that is attached to that hole with a simple knot, usually a cow hitch. Some earphones incorporate the audio signal into the lanyard, meaning it doubles up as headphone cords as well. The Wii Remote wrist strap is a form of lanyard, keeping the device attached to a player's arm during the often vigorous movements involved in its use.

Badge or identification holder Lanyards are commonly used to display badges, tickets or ID cards for identification where security is required, such as businesses, corporations, hospitals, prisons, conventions, trade fairs, and backstage passes used in the entertainment industry. Such lanyards are often made of braided or woven fabric or split with a clip attached to the end. A plastic pouch or badge holder with at least one clear side is attached to the lanyard with the person's name badge or ID card. Occasionally, small items like business cards, pens or tools can be placed behind the badge for easy access. Lanyards can also be used as keychains, particularly in situations where keys can easily be lost, such as gyms, public pools and communal showers. In these cases, lanyards may be customised with the related name and/or logo of the event, business, or organisation. Lanyards can feature a variety of customisation techniques including screen-printing, Jacquard loom weaving, heat transfer, and offset printing.

Safety strap Lanyards are also often attached to dead man's switches or "kill switches" on dangerous machinery, such as large industrial cutting or slicing machines, vehicles, jet-skis or trains, and exercise treadmills, so that if the operator suddenly becomes incapacitated, their fall will pull on the lanyard attached to their wrist, which will then pull the switch to immediately stop the machine or vehicle. Some law enforcement officers and members of the military utilise specialised lanyards to keep sidearms from falling to the ground during missions. Many ID card lanyards have a built-in feature known as a "breakaway" closure. Breakaway lanyards release when pulled or when pressure is applied. This prevents choking or hanging. Lanyards with a breakaway feature are most often used in hospitals and healthcare clinics, schools, nursing homes, child care facilities, and factories that require employees to operate machinery.

Lineman lanyards Lineman lanyards are used by lineworker utility and other workers to prevent falls, although similar straps are also used recreationally by mountain climbers. This type of lanyard will have a section of heavy-duty nylon strapping attached to a metal ring or carabiner which tightens around an attachment point. The strap may be a fixed length or adjustable, and will attach to the wearer to support them against a fixed object or pole.

Worked examples

Example 1 — a first encounter with Lanyard

Start with the simplest possible case. Write down what Lanyard claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lanyard before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lanyard ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lanyard

In research
Lanyard appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Lanyard in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Lanyard is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bracelets, Braids, Military uniforms, so understanding it makes those chapters shorter.
In everyday life
Look for Lanyard outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
