Accidental fire not intended to attack enemy/hostile targets, and deliberate firing on one's own troops for disciplinary reasons, is not called friendly fire,Regan, Geoffrey (2002) ''Backfire: a history of friendly fire from ancient warfare to the present day'', Robson Books and neither is unintentional harm to civilian or neutral targets, which is sometimes referred to as collateral damage. Training accidents and bloodless incidents also do not qualify as friendly fire in terms of casualty reporting.

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. Many colors of high visibility vests are available, with yellow and orange being the most common examples.

Traffic Sign
Traffic signs or road signs are signs erected at the side of or above roads to give instructions or provide information to road users. The earliest signs were simple wooden or stone milestones. Later, signs with directional arms were introduced, for example the fingerposts in the United Kingdom and their wooden counterparts in Saxony. With traffic volumes increasing since the 1930s, many countries have adopted pictorial signs or otherwise simplified and standardized their signs to overcome language barriers, and enhance traffic safety. Such pictorial signs use symbols (often silhouettes) in place of words and are usually based on international protocols. Such signs were first developed in Europe, and have been adopted by most countries to varying degrees. International conventions Various international conventions have helped to achieve a degree of uniformity in Traffic Signing in various countries.

Traffic Cone
Traffic cones, also called pylons, witches' hats, road cones, highway cones, safety 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. History Traffic cones were invented by Charles D. Scanlon, an American who, while working as a painter for the Street Painting Department of the City of Los Angeles, was unimpressed with the traditional wooden tripods and barriers used to mark roads which were damaged or undergoing repainting. Scanlon regarded these wooden structures as easily broken, hard to see, and a hazard to passing traffic. Scanlon's rubber cone was designed to return to an upright position when struck by a gl ...

Fairbank Company's Gold Dust Washing Powder (which used a breakthrough hydrogenation process in its formulation), and Hudson's heavily advertised product, Rinso, proved that there was a ready market for better cleaning agents. Henkel & Cie's "self-activating" (or self bleaching) cleaner, Persil; (introduced in 1907); the early synthetic detergent, BASF's Fewa (introduced in 1932); and Procter & Gamble's 1933 totally synthetic creation, Dreft (marketed for use on infant-wear)Eduard Smulders, Wolfgang ...
