Three, enterprises should set up safety warning signs.
The production and business operation entity shall set up obvious safety warning signs on the production and business operation sites and related facilities and equipment with large risk factors. Enterprise safety warning signs shall be set at the entrances of construction sites and factories, workplaces and prominent positions. The specific requirements of different types of banks (enterprises) are as follows:
1, hazardous chemicals enterprise. Workplaces, safety facilities and equipment, special warehouses for hazardous chemicals and pipelines for hazardous chemicals laid by units producing and storing hazardous chemicals; Dangerous chemicals transport vehicles; Ships carrying dangerous chemicals are sailing, loading and unloading or berthing in inland rivers; Packaging and transportation of dangerous chemicals.
Fireworks production enterprises, wholesale enterprises, production areas, general warehouse areas, work (library) rooms and other places of production and business operations with greater risk factors and related facilities and equipment; Retail premises (inflammable and explosive).
2. Metallurgical enterprises and non-ferrous metal enterprises. Places with large risk factors, facilities and equipment, and places where gas leakage and gathering may occur in enterprises that produce, store and use gas.
3. Industry and trade enterprises. A workplace with limited space.
4. Food production enterprises. Places with risk factors and related facilities and equipment.
5. Small open-pit quarry. Access roads and related hazards.
6, coalbed methane enterprises. In the key monitoring areas of hydrogen sulfide, it is possible to form gathering places and compressor rooms for hydrogen sulfide and sulfur dioxide; Places and facilities such as well site entrance, drilling floor and derrick ladder, drilling floor, aerial work area, winch, diesel engine, generator and other mechanical equipment, oil tank area, fire fighting equipment room and fire fighting equipment box; Protective containers for transporting radioactive sources, outdoor and outdoor radioactive source warning areas; Along the pipeline; Station entrance, fence (fence), coalbed methane storage tank area, machine room and deployment area.
Four, set the principle of safety warning signs
1. standard: graphics, dimensions, colors and materials shall meet the standard.
2. Safety: After setting, there should be no potential danger in itself to ensure safety.
3. Eye-catching: the setting position should be eye-catching.
4. Convenience: the location and angle should be convenient for people to observe and capture information.
5. Coordination: All signboards set in the same place should try to keep their height and size in harmony with the surrounding environment.
6. Rationality: Use appropriate safety signs to reflect necessary safety information as far as possible to avoid omission and disorderly design.
Five, the basic requirements of the use of safety warning signs
1. Safety warning signs that can provide corresponding safety information must be set at important parts and key parts with safety risks on site. According to relevant regulations, site entrances and exits, construction hoisting machinery, temporary electricity facilities, scaffolding, access openings, stairs, elevator wellheads, holes, foundation pit edges, storage places for explosives and toxic and harmful substances are important parts with safety risks, and obvious safety warning signs should be set. For example, fireworks and other prohibited signs are not set in the storage places of explosives and toxic and harmful substances; Set warning signs such as sadness and hand injury beside the woodworking circular saw; Set warning signs such as safe passage at the entrance of the passage.
2, safety warning signs should be set in the relevant dangerous places or equipment attached to the most easily observed place.
3. Safety warning signs should be set in a bright and well-lit environment. For example, if the additional light is dim where the sign should be set, you should consider the additional auxiliary light source.
4, safety warning signs should be firmly fixed on the bracket, can't produce the phenomenon such as tilt, warping, swing, height should be consistent with the line of sight of human eyes as far as possible.
5. Do not set safety warning signs on movable objects such as doors, windows and shelves. There should be no fixed obstacles in front of or near the warning signs that prevent people from trying to read, and try to avoid being often blocked by other temporary objects.
6. When multiple safety warning signs are arranged together, they should be arranged from left to right and from top to bottom in the order of warning, prohibition, instruction and prompt. The distance between signs should be at least 0 or 2 times the size of the signs.
7, when there is a danger of electric shock, should choose safety warning signs made of insulating materials.
8. Warning signs made of reflective materials or self-luminous materials should be selected for fire safety signs in outdoor open space.
9. For places with fire prevention requirements, safety warning signs made of incombustible materials should be selected.
10, register the site layout of safety warning signs, draw the general plan of safety warning layout, and arrange according to the plan. If the layout point changes, it should be updated in time.
1 1. Without permission, no one is allowed to move, displace, dismantle or change the safety warning signs on the site.
12, the construction site should strengthen the inspection of the layout of safety warning signs. If it is found to be damaged, deformed or faded, it should be repaired or replaced in time.
