2. Before hot work, the operator must confirm the safety of the site and identify the areas (up, down, front, back, left and right) where high-temperature slag, sparks and other kindling may or may splash. It is forbidden to have any flammable materials (explosives, cartons, plastics, wood, oil, cotton cloth and other flammable materials). ) around 65,438+00 meters to ensure that the hot work area is maintained.
3. When unconditionally removing combustible materials, equipment and tools that may be affected or damaged during hot work, the operator must effectively isolate the hot work area from the external area, fire and equipment to be protected with tight iron plates, asbestos tiles and fire nets, and prepare fire-fighting equipment and water sources at the scene. If necessary, water this part irregularly.
4. Before hot work at heights, operators must determine the areas that may be on fire or may be on fire, find out whether the surrounding environment is full of flammable substances, and confirm and clean up the site according to regulations to prevent fire and explosion accidents caused by fire splashing.
5. It is strictly prohibited to blindly ignite all containers, equipment and pipelines containing oil and paint thinner under pressure and high temperature. When it is necessary to put out the fire under special circumstances, it is necessary to ensure that the containers, equipment and pipelines are under normal temperature and pressure. Before hot work, the surrounding environment of containers and equipment must be checked, thoroughly purged, cleaned and replaced, and hot work can only be started after repeated confirmation that there are no hidden dangers; Hot work must be supervised by a special person, and fire-fighting equipment and water sources must be prepared on site. If necessary, this part can be sprayed with water irregularly.
6. When carrying out hot welding and gas cutting operations in the no-fire area, it is necessary to identify the danger, formulate a safe hot work plan and implement fire safety measures. Welding and gas cutting can only be carried out after being signed by workshop leaders and reported to relevant leaders for approval, and corresponding safety measures are taken.
7. When using gas welding and gas cutting for hot work, the distance between oxygen cylinder and acetylene cylinder shall not be less than 5m, and the safe distance from the hot work site shall not be less than 10m. Oxygen cylinder ports, pressure reducing valves and valves shall not be contaminated with grease and oil, and acetylene cylinders shall not be placed horizontally. When transporting, storing and using gas cylinders, it is forbidden to collide, knock or roll violently, and the gas cylinders should be placed firmly to prevent dumping.
8. Before hot work, check the welding machine and gas cylinder (pressure reducing valve, hose, cutting torch, etc. ), cables and other electrical appliances, to ensure that in good condition, wires without damage, leakage, jamming, disorderly pull and other unsafe factors; The grounding wire of electric welding machine should be directly lapped on the weldment, and it is not allowed to be connected randomly, in case of fire or leakage caused by poor contact, fever and ignition, causing casualties.
9, after the hot work, the operator must confirm the safety of the surrounding scene, tidy up the scene, in the case of confirmed without any fire hazards, can leave the scene.
10, it is strictly forbidden for foreign, irrelevant non-operating personnel to use welding and gas cutting tools casually, and stop them immediately once found.
