Fire safety requirements for the hottest hot work

Fire safety requirements for hot work

1 fire safety requirements for special dangerous hot work

hot work application form must be handled for hot work, and hot work can be carried out under the on-site supervision of firefighters only after it is approved (signed and approved) by the safety director

2 fire safety requirements for class I hot work

hot work application form must be handled during hot work, and hot work can be carried out only after it is approved by the plant safety and fire department and arranged for firefighter on-site supervision

3 fire safety requirements for class II hot work

hot work application form must be handled during hot work. After being approved by the plant safety and fire department, firefighters can be arranged to follow up, and hot work can be carried out

4 fire safety requirements for class III hot work

hot work can be carried out without arranging firefighters after being reported to the safety and Fire Department of the plant

5 all containers, equipment, pipelines and other production and storage devices that contain or contain dangerous chemicals must be cleaned and replaced before hot work, which marks that 3D printing technology has made greater progress in the manufacture of high durability final parts, and hot work can be carried out

6 before hot work, check the operation site and below to ensure that there are no inflammables, otherwise it must be cleaned and removed. If it cannot be removed or removed, it should be covered with non combustible materials

7 when hot work is carried out on the ground and there are combustibles around, fire prevention measures should be taken. If there are underground shafts and trenches near the hot work point, the dynamic performance requirements and water seals of the fatigue testing machine should be checked, and corresponding safety and fire prevention measures should be taken according to the specific situation of the site

8 hot work is prohibited on the equipment that produces, uses and stores inflammables such as liquefied gas

9 it is normal weather (including level 5 wind) to use the jaw for a long time and contact the material for damage above level 5 wind, and open-air hot work is prohibited. When hot work is really needed due to production needs, hot work shall be upgraded

10 hot work should be supervised by a specially assigned person. Before hot work, inflammables on and around the hot work site should be removed, or other effective safety and fire prevention measures should be taken, and sufficient and applicable fire-fighting equipment should be equipped

11 before hot work, electric and gas welding tools should be checked to ensure safety and reliability, and they are not allowed to be used with diseases

12 when using gas welding and cutting for hot work, the distance between oxygen cylinder and acetylene cylinder shall not be less than 5 meters, and the distance between them and the hot work site shall not be less than 10 meters, so that the instrument is often kept clean, parts and accessories are complete and safe, and it is not allowed to be exposed to the sun

13 hot work along the Plant Road (within 15 meters) must be stopped immediately when a vehicle containing dangerous chemicals passes or stops

14 all equipment polluted by chemical substances or grease should be cleaned before using open fire

15 during welding/gas cutting operation, it is strictly prohibited to use open fire for pressurized equipment. Before hot work for pressurized equipment, the pressure must be relieved first. There are explosives inside the equipment parts, and hot work is strictly prohibited if it is not easy to check outside

16 work at heights shall be protected by fire plate or iron sheet or incombustible objects to prevent splashing of fire stars

17 when hot work is carried out at high altitude, if there are dyeable objects, cavities, Yin wells, trenches, water seals, etc. on the lower ground, they should be checked and analyzed, and measures should be taken to prevent fire and explosion accidents caused by the splashing of fire flowers

18 inflammables at the hot work site, such as gasoline, Tianna water, paint, acetone, etc., must be 10m away from the fire source, O2 cylinders must be 5m away from acetylene cylinders, and O2 cylinders and acetylene cylinders must not be less than 10m away from the fire source

19 when hot work is carried out inside cooling towers, water washing towers, etc. with combustible or non combustible components, fire prevention and isolation measures must be taken to prevent fire from splashing down

20 after the hot work is completed, the site should be cleaned and left for observation for more than 15 minutes. After confirming that there is no residual fire, you can leave
