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

Reference answer:

The style of warning signs has national standards.

signboard material:

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

2. The national standard size of safety signs:

A 5*4 B 4*32 C 3*24 D 2*16

The conventional size is also 2*25 3*2 8*65 2*16

3. Signboard contents: < No kindling, no climbing, no using wireless communication, no mixing, no drinking, no wearing chemical fiber clothing, no approaching, no jumping, no passing, no crossing, no touching, no staying, no working after drinking and no flammable materials.

(2) Warning safety signs series: beware of corrosion, explosion, poisoning, fire, safety, electric shock, cable, mechanical injury, hanging objects, falling objects, foot sticking, vehicles, roof caving, gas, hot hands, collision, tripping, harmful gas, infection, dust, falling water, and falling water.

(3) Command safety sign series: safety helmet, safety belt, protective mask, cleanliness, work clothes, protective gloves, protective devices, upper channel, lock, self-rescuer, miner's hat and miner's lamp must be worn.

(4) Common power safety signs and signs series: no entry without permission, no switching on and no work, no entry for idle people in power distribution areas, high voltage danger, no entry for idle people in power distribution areas, no work here and from now on.

4. use environment of signboard

power, lines, traffic, communication, safety warning, public information, fire safety, construction site, construction site safety, production safety, mine safety, etc.

5. Function of safety signs:

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

Warning signs:

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 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 sign to remind other vehicles to avoid it, so as to avoid a secondary accident.

2. Action principle:

The reflective part of the warning sign is made by using the regression reflection principle of glass beads with high refractive index and the micro-rhombic reflection principle of reflective lattice through the advanced technology of focusing and post-processing. It can reflect distant direct light back to the light emitting place, and has good retro-reflective optical performance no matter in 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 drivers at night, whether the user is in a distant place or under the interference of light or scattered light. The appearance of reflective materials successfully solved the problem of "seeing" and "being seen" driving at night.

3. Precautions:

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

It is recommended to choose the foldable reflective warning sign, because when the vehicle has problems and needs to be stopped for inspection, it should be placed 5 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 much space in the car.

4. Installation location:

Generally speaking, drivers need to go through a process of finding the warning signs ahead, clearly seeing the warning signals ahead, taking measures to brake, slow down and avoid. Take a car traveling at 1 kilometers per hour as an example. Generally speaking, it takes at least 1.8 seconds of reaction time or at least 35 meters. This requires the warning sign to be highly reflective, so that the driver can see it at the first time.
