A danger sign is an image specially created and approved by the international commission that warns of a situation that could adversely affect human health or lead to death. Naturally, everyone should know them. Only in this case can you save yourself from trouble.
Why are danger signs needed and what features do they have?
Perhaps not everyone understands how important the images presented are. However, there are several factors that confirm the need to use such signs:
- You will always know where there is the possibility of radiation damage or chemical poisoning;
- a picture will help you understand where there are dangerous places that need to be circumvented;
- in case of transportation of any goods, a danger sign will show how harmful they are to us.
In any case, the images presented can save a person’s life, warn him of an imminent threat.
It should be noted that the background on which the picture will be drawn may be different in different countries: yellow, red, orange and even blue. Therefore, it is important to know the meaning of the main image.
What are the technical requirements for the marks presented?
Each picture is a signal of danger, so it should be clearly visible. All parameters for the manufacture of such signs must be prescribed in the relevant regulatory documents. For example, the image should be bright enough so that it can be easily seen. In addition, it should not deteriorate under the influence of the external environment (rain, snow, wind, sunlight).
The danger sign must be painted with a paint that does not wear off after several months of use. In practice, fluorescent substances that can glow in the dark are often used. Thanks to this, you can protect yourself at any time of the day. If necessary, the image is additionally illuminated without fail. At the same time, lamps should not change the color of the picture or impair its visibility.
A hazard sign is mainly made of sheet metal. The use of plastic in this case is undesirable, since it is less durable.
Now you can take a closer look at which pictures are used to warn people.
The meaning and features of the use of hazard signs in the transport of goods
Presented marks are attached not only to potentially hazardous objects, but also to the transport that carries them. Naturally, they have their own characteristics of use:
- cargo hazard signs are mounted on cars, containers, tanks, packaging, and this must be done on the sides and front side;
- on cars, such designations are additionally glued on the back;
- in case there should be several signs on one product, they should be attached side by side.
After the cargo is delivered to its destination, and the container is unloaded, the signs must be removed. On the plates with the picture should be an orange background. In any case, the signs are well attached. They usually indicate the cargo identification number , hazard level. Each degree corresponds to a certain amount of harm that a substance can cause in the event of a traffic accident or improper storage.
Significance and features of the use of radiation hazard signs
The next group of notations talks about places where a high level of radiation is observed. For this, a well-known sign was invented by everyone: a black trefoil on a yellow background. The shape of the plate is a triangle. This image is installed in all those places where there is a possibility of infection or there is an increased radiation background: at nuclear plants, in “exclusion zones” that appeared after environmental disasters.
In 2007, the International Atomic Energy Organization decided to provide a new designation: a red triangle, which shows a figure of a runaway person, a shamrock with radiation, and a skull. However, such a sign of radiation hazard is hardly successful. It is quite complicated both for understanding and for manufacturing. In any case, such an image should be applied to any potentially unsafe object, building or site.
The meaning and features of the use of signs of chemical hazard
It is hard to imagine a modern existence without the achievements of chemistry. Naturally, such substances are more often used for the benefit of mankind, but they do not become less dangerous for it. Therefore, certain signs were invented that indicate the transportation or storage of chemistry.
The most popular image is biohazard. Most often it has a black color and is placed on an orange (yellow) background. Another widely known image is a skull with bones. He bluntly says that there is a zone nearby that you should not be in.
A chemical hazard sign is applied to vehicles (tanks, barrels, cars, containers) in which the substance is transported (stored). Naturally, it is painted on the warehouse, which contains a chemical agent. There are also many other pictograms that are applied to the packaging of potentially harmful goods. For example, you will know that there is an explosive or flammable substance, acid, poisonous liquid in the cylinder.
Some pictograms warn us about those products that contain carcinogenic components, can cause irreversible changes in the body, contribute to allergies, cause burns, injuries.
The meaning and features of the use of fire hazard signs
This group of notations is used to indicate those objects, objects or territories that have a high degree of flammability. Fire hazard signs are often affixed to vehicles transporting gasoline, oil, or other substances that can quickly catch fire and even explode.
In addition, they are installed in storage facilities in which ammunition and equipment are stored. They are also mounted on the doors of the room where the unsafe cargo lies. If the sign is attached to the gates of the facility, then the entire territory is under the influence of conditions that could provoke a fire.
