High-visibility clothing, sometimes shortened to hi vis or hi viz, is any clothing worn that is highly luminescent in its natural matt property or a color that is easily discernible from any background. It is most commonly worn on the torso and arm area of the body. Health and safety regulations often require the use of high visibility clothing as it is a form of personal protective equipment. [1] [2] [3] Many colors of high visibility vests are available, with yellow and orange being the most common examples. Colors other than yellow or orange may not provide adequate luminescence for conformity to standards such as ISO 20471.

As a form of personal protective equipment, high-visibility clothing is worn to increase a person's visibility and therefore prevent accidents caused by persons not being seen. As a result, it is often worn in occupations where hazardous situations are created by moving vehicles or low lighting conditions. These occupations include railway and road workers, airport workers and emergency services. Cyclists and motorcyclists may also use high-visibility clothing to increase their visibility when operating amongst motor traffic. [4] Hunters may be required to wear designated high-visibility clothing to prevent accidental shooting.


Effectiveness

Motorcyclists

A police officer in Taiwan wears a white motorcycle helmet in conjunction with a high-visibility vest. According to a 2004 study, the wearing of reflective or fluorescent clothing correlated with a 37 percent lower risk of a rider sustaining a crash-related injury; likewise, white helmets demonstrated a 24 percent reduction.

The Hurt Report found that very few motorcyclists involved in collisions wore high-visibility clothing, and that just over half of the collisions studied, nearly two-thirds of those involving another vehicle, were due to the motorist unintentionally violating the motorcyclist's right of way. "This dominant culpability of the driver of the other vehicle... emphasizes the special need for high contrast conspicuity for the motorcycle and rider." [5]

A New Zealand case-control study found that the population attributable risks were 33% for wearing no reflective or fluorescent clothing; one third of motorbike accidents might have been prevented by wearing high-visibility clothing. Conspicuous behaviors, such as the wearing of high-visibility clothing, the use of headlights in the daytime, and the use of a white helmet, reduced the risk of a rider facing a collision. [5]

Cyclists

Traffic risks to the cyclist are similar to those faced by motorcyclists, with the main differences being that cyclist speeds are typically lower, and the cyclist wears less protective gear. In a 2009 study, most UK cyclists and almost all motorists believed that high-visibility clothing would increase cyclists' visibility. Almost all drivers agreed that cyclists need to wear reflective clothing in low lighting environments, whereas less than three-quarters of cyclists (72%) agreed, and less than half claimed that they always did so. [6]

A Cochrane Systematic Review of research evidence for the effectiveness of visibility aids (fluorescent and retroreflective clothing and equipment) was carried out by Kwan and Mapstone in 2006. [7] The authors found 42 studies which collectively suggested that fluorescent clothing could increase the distance at which drivers could detect and then recognise cyclists in daylight conditions. [7] The same review found evidence that retro-reflective materials worn by cyclists at night had a similar effect on driver perceptions. At that time there were no studies published that had actually demonstrated a reduction in collision crashes for bicyclists wearing fluorescent or retroreflective clothing whilst on public roads.

A 2009 Australian study of drivers trying to see stationary cyclists on a closed circuit found that fluorescent vests (without retro-reflective stripes) were not a significant improvement on black clothing at night and that retro-reflective strips were more effective when attached to knees and ankles than on a more or less static jacket. [8]

A 2012 British case-control study showed a non-significant increase in the odds of a crash for users of reflective conspicuity aids whilst cycling. [9] In 2014, a further case-control study conducted in Canada reported a decrease in the odds of a collision with a motor vehicle when wearing 'light' coloured (not specifically fluorescent) clothing in daylight but an increase in the odds of a collision for cyclists using fluorescent clothing (and lights) at night. The number of conspicuity aids used was positively associated with an increase in collision crash odds but a non-significant reduction in the likelihood of hospitalisation. [10]

A randomized controlled trial was conducted in Denmark between 2012 and 2013. [11] The study collected data from 6793 regular cyclists for a year. [11] The results suggest that conspicuity enhancing jackets can reduce by 47% the risk of collisions with other road users that cause injury and 55% for those collisions involving a motor vehicle. [11] The effect of the intervention was higher in winter compared to summer (56% vs 39%), in daylight (51% vs the overall effect 47%) and for those participants who reported 'high' use of the jackets vs 'low' use (60% vs 33%). [11] The study was based on participants self-reporting data, and there was evidence of response bias, which the authors attempt to correct for, reducing the 47% figure to 38%. [11]

Since April 2013, New York City regulations require commercial cyclists, such as restaurant delivery persons or bike messengers, to wear high visibility clothing while riding. [12]

Experimental use of high-visibility clothing began in 1964 on the Scottish Region of British Railways. [13] Fluorescent orange jackets, known as "fire-flies", were issued to track workers on the Pollokshields to Eglinton Street electrified section in Glasgow; [14] they were later tried in other areas, such as Edinburgh, Aberdeen and Inverness. Train drivers operating in these areas were asked their opinion as to the effectiveness of the jackets. [13] Following trials, high-visibility clothing was issued to engineering and other staff working on the electrified lines of the London Midland Region of British Railways in 1965. It was thought to be more important due to the higher speeds of the newly electrified West Coast Main Line route from London Euston to Birmingham, Manchester and Liverpool. The first version was worn as a jerkin and was "visible at ... half a mile in normal weather conditions". [15]

Since then, features of high-visibility clothing such as the EN510 quick release standard and the EN471 and its successor EN ISO 20471:2013 high visibility standards, have improved the effectiveness and contributed to improved safety for rail workers and other staff. [16] The specifications for Rail Industry Standard RIS-3279-TOM (fluorescent orange) high-visibility clothing suitable for use on railways in the United Kingdom are published by the Rail Safety and Standards Board. [17]

India

The latest Indian standards for High Visibility Warning Clothes - Specification is IS 15809 : 2017.

ANSI/ISEA

The American National Standards Institute published standard 107 [18] for high-visibility clothing in 1999. The standard defines three classes of successively more-visible garments, to protect workers exposed to successively higher levels of risk from motor vehicles and heavy equipment. The International Safety Equipment Association developed the standard, with revisions in 2004, 2010 and 2015. [19] [20] [21]

The 207 standard has different requirements for fluorescent background material, specifically allowing for a shorter design that allows equipment belt access. It also includes many optional features, such as a 5-point breakaway design for easy removal, panels readily identifying the wearer as an emergency responder, and radio and badge holders. [22]

Deer hunters wearing blaze orange for identification as humans, not game animals

Hunting laws in each state or province may require hunters to wear designated garments in blaze orange to prevent misidentification of humans as game animals, and resulting shooting accidents. The required total visible area and times of use vary by jurisdiction and by the type of hunting in the area. Hunting clothes are available in blaze orange camouflage, where the bright orange color is plainly visible to human eyes, but the shape of the hunter is broken up by irregular patterns to prevent identification as a threat by game animals such as deer, who cannot see the color. [24] Some jurisdictions also allow the use of a "blaze pink," a color that proponents argue is both more visible to humans and less visible to game animals. [25]

Motorcycle safety is another important things that every biker needs to carry. Many countries mandate the wearing of personal protective equipment such as protective clothing and helmets. Protective clothing may include certain types of jackets, gloves, boots, and pants. Jackets meant for motorcyclists are typically made of leather or specialized man-made fabrics like cordura or Kevlar. These jackets typically include padding on the elbow, spine, and shoulder regions. This was once quite bulky, but modern technology and materials have made it unobtrusive. Gloves are generally made of leather or Kevlar and some include carbon fiber knuckle protection. Boots, especially those for sport riding, include reinforcement and plastic caps on the ankle and toe areas. Pants are usually leather, cordura, or Kevlar. Except for helmets, none of these items are required by law in any state in the USA, or in any part of the UK but are recommended by many of those who ride.

A motorcycle helmet is a type of helmet used by motorcycle riders. Motorcycle helmets contribute to motorcycle safety by protecting the rider's head in the event of an impact. They reduce the risk of head injury by 69% and the risk of death by 42%. Their use is required by law in many countries.

<span class="mw-page-title-main">Hard hat</span> Helmet type

A hard hat is a type of helmet predominantly used in workplace environments such as industrial or construction sites to protect the head from injury due to falling objects, impact with other objects, debris, rain, and electric shock. Suspension bands inside the helmet spread the helmet's weight and the force of any impact over the top of the head. A suspension also provides space of approximately 30 mm between the helmet's shell and the wearer's head, so that if an object strikes the shell, the impact is less likely to be transmitted directly to the skull. Some helmet shells have a mid-line reinforcement ridge to improve impact resistance. The rock climbing helmet fulfills a very similar role in a different context and has a very similar design.

Traffic cones, also called pylons, witches' hats, road cones, highway cones, safety cones, caution cones, channelizing devices, construction cones, or just cones, are usually cone-shaped markers that are placed on roads or footpaths to temporarily redirect traffic in a safe manner. They are often used to create separation or merge lanes during road construction projects or automobile accidents, although heavier, more permanent markers or signs are used if the diversion is to stay in place for a long period of time.

<span class="mw-page-title-main">Bicycle lighting</span> Illumination devices attached to bicycles

Bicycle lighting is illumination attached to bicycles whose purpose above all is, along with reflectors, to improve the visibility of the bicycle and its rider to other road users under circumstances of poor ambient illumination. A secondary purpose is to illuminate reflective materials such as cat's eyes and traffic signs. A third purpose may be to illuminate the roadway so that the rider can see the way ahead. Serving the latter purposes require much more luminous flux and thus more power.

<span class="mw-page-title-main">Raised pavement marker</span> Road safety device

A raised pavement marker is a safety device used on roads. These devices are usually made with plastic, ceramic, thermoplastic paint, glass or occasionally metal, and come in a variety of shapes and colors. Raised reflective markers, such as plastic, ceramic, or metal ones, include a lens or sheeting that enhances their visibility by retroreflecting automotive headlights, while glass road studs gather automotive headlights with a dome shape and reflect the lights with a reflective layer within. Some other names for specific types of raised pavement markers include convex vibration lines, Botts' dots, delineators, cat's eyes, road studs, or road turtles. Sometimes they are simply referred to as "reflectors".

<span class="mw-page-title-main">Safety orange</span> Color

Safety orange is a hue used to set objects apart from their surroundings, particularly in complementary contrast to the azure color of the sky. The high-visibility color is commonly used for hunting during the rifle season, and is also used for upland-bird hunting. Places such as construction sites use this orange to help ensure the safety of others.

<span class="mw-page-title-main">Retroreflective sheeting</span> Reflective material

Retroreflective sheeting is flexible retroreflective material primarily used to increase the nighttime conspicuity of traffic signs, high-visibility clothing, and other items so they are safely and effectively visible in the light of an approaching driver's headlamps. They are also used as a material to increase the scanning range of barcodes in factory settings. The sheeting consists of retroreflective glass beads, microprisms, or encapsulated lenses sealed onto a fabric or plastic substrate. Many different colors and degrees of reflection intensity are provided by numerous manufacturers for various applications. As with any retroreflector, sheeting glows brightly when there is a small angle between the observer's eye and the light source directed toward the sheeting but appears nonreflective when viewed from other directions.

<span class="mw-page-title-main">Safety reflector</span> Safety item that reflects light

A safety reflector is a retroreflector intended for pedestrians, runners, motorized and non-motorized vehicles. A safety reflector is similar to reflective stripes that can be found on safety vests and clothing worn by road workers and rescue workers. They are sometimes erroneously called luminous badges or luminous tags, but this is incorrect as they do not themselves produce light, but only reflect it.
