Safety signs, or danger symbols, warning signs, caution symbols, as they are called in different parts of the world, are labels, letters, and symbols that indicate the precautions that must be taken to ensure attention, care, danger, risk, safe behaviour, etc. regarding life and personal effects. These are specially notified in public areas to raise awareness among people about the dangers and dangers of certain situations, not following the regulations and putting their own and others’ lives at stake.
There are various categories of safety or warning signs that specifically indicate or warn of obstacles, hazards, risks, etc. to prevent accidents, disasters and environmental hazards that affect the general population.
A traffic sign is a type of warning sign to indicate hazards or hazards on the road that are not easy for a driver to see. In many countries, these signs are usually in the shape of an equilateral triangle with a thick red border on a white background; background and border colors vary from country to country.
Traffic signs usually contain a symbol or a combination of words and symbols. European traffic signaling is based on the UNECE Vienna Convention on Road Signs and Signals; in the US, the MUTCD standard is followed and often contains only words or text.
Early roadside signs, or milestones as they were called, only provided distances between locations. Among the first safety warnings to appear in the mid-1960s was the warning about horse-drawn carriages and stone-carved vehicles; the Alfama area in Lisbon was one of the first to have them. But primitive signs did not have access to high-contrast letters and symbols and were mostly overlooked.
Safety signs or warning signs are used in many areas of public interaction: road and traffic marking, general caution, obstacles, animal crossings, road works, tunnels, bridges, construction work, presence of harmful substances such as chemicals , etc.
Traffic signals
With the advent of automobiles in the 1900s, the first safety or warning signs were erected in West London. In 1910, nine European countries established a common symbol using images for road markings to indicate potholes, curves, intersections and railway crossings. Over the next few decades, intensive signage research and development work culminated in the development of the European Road Signage System. By the turn of the century, as vehicle volumes and traffic increased and night driving gained significant progress, flat painted signs gave way to raised letter signage and later to illuminated signs and reflectors to allow drivers watch the signs at night.
In the modern era, safety and warning signs have taken on different colors and shapes to indicate the category of danger or risk.
• General Caution: Typically, a diamond-shaped sign with an exclamation point in the middle serves as a general warning or caution; Explanatory language and pictograms are also used.
• Obstacles or Slow Moving Areas: Rectangular or diamond-shaped signs with reflectors are placed on roads, streets, highways, and public areas to indicate roadblocks, bridge abutments, curves, curves and corners, curves, dividers, poles, tunnels ahead, level crossings, school zones, hospitals, pedestrian crossings, etc.
• Animals Crossing the Road: Wild animal signs at road junctions through brush forest areas, dense jungle, or where particular animals live in large populations serve as warning messages to drive slowly to avoid hitting an animal. Common animal crossing chants are alligators, bears, camels, deer, moose, kangaroos, polar bears, reindeer, kangaroos, etc. Large farms or ranches sometimes post signs to watch out for cows, ducks, horses, and sheep so they don’t get hit by passing trucks or vehicles.
• Road works or construction: These are temporary signs to indicate building construction, road repair works, temporary obstructions such as floods, road collapses, poor road conditions, loose soil, newly laid roads and many others, and sometimes Often, they are accompanied by speed. limitations. The colors of these signs vary from country to country, from white to bright yellow, orange, red and blue.
