Safety signs, or hazard symbols, warning signs, caution symbols, as they are called in different parts of the world, are labels, letters, and symbols that indicate precautions that must be taken to ensure attention, care, danger, risk, safe behavior, etc. regarding life and personal effects. These are especially 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 lives and those of others at risk.
There are several 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 risks or hazards on the road that are not easy for a driver to see. In many countries, these signs are usually in the form of an equilateral triangle with a thick red border on a white background; background and border colors vary from country to country.
Traffic signs often 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, it follows the MUTCD standard and often contains only words or text.
The first 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 of Lisbon was one of the first to have them. But primitive signs did not have access to high-contrast letters and symbols and were often overlooked.
Safety signs or warning signs are used in many areas of public interaction: road and traffic signs, general caution, obstacles, animal crossings, road works, tunnels, bridges, construction work, the 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 that uses images for road markings to indicate potholes, curves, intersections and railway crossings. Over the next few decades, intense research and development work on signage culminated in the development of the European Road Signage System. By the turn of the century, as vehicle and traffic volumes increased and night driving made 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: Generally, 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.
• Slow Moving Areas or Obstacles – Rectangular or diamond-shaped signs with reflectors are placed on highways, streets, highways, and public areas to indicate barricades, 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 crossings through areas of forest scrub, 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. Sometimes large farms or ranches 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 work, temporary obstructions such as flooding, road collapses, poor road conditions, loose soil, newly laid roads, and many others, and sometimes They are often accompanied by speed. limitations. The colors of these signs vary from country to country, from white to bright yellow, orange, red and blue.
