Is there a national standard for the style of warning signs?

The style of warning signs has national standards.

Signboard materials:

PVC, enamel, aluminum reflective, stainless steel, aluminum anti-corrosion, etc.

2. National standard size of safety signs:

a 500 * 400 B 400 * 320 C 300 * 240D 200 * 160

The conventional size is 200 * 250 300 * 200 80 * 65 200 *160.

3. Signboard content:

⑴ Safety signs series: No fireworks, no opening, no smoking, no entering, no working on closed lines, no kindling, no climbing, no wireless communication, no mixing, no drinking, no wearing chemical fiber clothing, no approaching, no jumping, no passing, no crossing, no touching, no staying, no posting after drinking, and no flammable materials.

⑵ Warning safety sign series: beware of corrosion, explosion, poisoning, fire, safety, electric shock, cable, mechanical injury, hanging objects, falling objects, feet sticking, vehicles, roof caving, gas, burning hands, bumping, tripping, harmful gas, infection, dust prevention, falling into water and natural gas explosion.

(3) Command safety sign series: safety helmet, safety belt, protective mask, cleaning products, work clothes, protective gloves, protective devices, access, locks, self-rescuers, miners' hats and miner's lamps must be worn.

⑷ Series of common signs and signs for power safety: no entry without permission, no closing and no work, no idle people in distribution area, high voltage danger, no idle people in distribution area, no work here and no going up and down from now on.

4. The use environment of the logo

Electric power, lines, transportation, communication, safety early warning, public information, fire safety, site construction, site safety, production safety, mine safety, etc.

5. The role of safety signs:

Hanging safety signs is the main technical measure to ensure the safety of staff.

Warning sign:

Warning signs are conventional emergency equipment in automobiles, and their appearance is generally triangular, so they are also called triangular warning signs. Warning signs must be passive reflectors made of plastic reflective materials in strict accordance with the requirements of the Road Traffic Safety Law. The principle is that when the owner encounters a sudden traffic accident on the road, he uses the reflective performance of the warning signs to remind other vehicles to avoid the second accident.

2. Principle of action:

The reflective part of the warning sign is made by using the regression reflection principle of high refractive index glass beads and the micro-rhombic reflection principle of reflective lattice, and through the advanced technology of focusing and post-processing. It can reflect the distant direct light back to the light-emitting place, and has good retro-reflective optical performance no matter day or night.

Especially at night, the visibility can be as high as during the day. The warning sign made of this high-visibility reflective material can be easily found by the driver at night, no matter the user is far away or under the interference of light or scattered light. The emergence of reflective materials has successfully solved the problems of "seeing" and "being seen" when driving at night.

3. Precautions:

When choosing warning signs, you must choose products with guaranteed quality, because whether the vehicles behind you find warning signs in time is the key to avoid rear-end accidents within a safe enough distance.

It is recommended to choose folding reflective warning signs, because when the vehicle has problems and needs to be stopped for inspection, it should be placed 50 meters away from the rear of the vehicle to remind the driver to slow down in advance; When not in use, the foldable warning sign will not occupy too much space in the car.

4. Installation location:

Generally speaking, drivers need to go through a process of finding the warning signs ahead, seeing the warning signals ahead clearly, taking measures to brake, slow down and avoid. Take a car with a speed of100km as an example. Generally speaking, it takes at least 10.8 second or at least 350 meters. This requires the warning signs to be highly reflective so that drivers can see them at the first time.
