2. Scope of application: all hot work in the company's construction, maintenance and emergency rescue.

3. Responsibilities: When hot work is carried out in the fire-forbidden area, a hot work permit must be obtained. Handling and use of hot work permit: In the no-fire area, any work that can produce flames, sparks and hot surfaces is hot work, and hot work procedures must be handled. Hot work without a license is strictly prohibited, otherwise it will be severely punished. Electricians must have a valid hot work permit to connect the welding machine, otherwise they will be severely punished. When applying for hot work, all hot work measures shall be implemented in accordance with hot work safety regulations, and hot work guardians (not less than 2 persons) shall be arranged before applying for hot work. The hot work permit shall be handled by the designated person applying for hot work or the person in charge of the hot work project. The hot work permit shall be examined and approved, and the hot work in special dangerous areas shall be reported for examination and approval. When the security department asks the person in charge of hot work about the preparation work before hot work, it must answer truthfully, otherwise it will be dealt with seriously. Hot work must be carried out within the effective time and area approved by the hot work permit. Any extension or supplementary hot work must be reissued with a "Hot Work Permit". When hot work personnel arrive at the hot work site, they must first check whether all measures in the hot work permit are implemented. If one of them is not implemented, it has the right to refuse hot work. The Hot Work Permit shall be carried by the hot work operator and shall not be transferred, and the hot work site shall not be altered or transferred. When the hot card is approved, it must be inspected on site and confirmed to be safe and reliable before the "hot card" can be issued. Safety measures during hot work: clean the flammable and combustible substances in the hot work equipment thoroughly before use, and keep it for enough time and times to ensure that there is no flammable or explosive gas or liquid in the container, and finally fill it with clear water. Cut off the pipeline connected with the hot work container equipment, add equipment blind plate, and completely isolate the flammable and explosive articles in the hot work room. When hot work is carried out, explosion analysis and oxygen content determination should be carried out, and hot work can be carried out only after it is qualified, and an approval form must be issued to the security department. Detachable pipes, valves, etc. It should be removed as far as possible and taken to a safe place for hot work. If the replaced equipment and accessories need to be reused, they should be cleaned before installation during hot work. Before hot work, we should consider and contact as a whole. If there is a threat to hot work and the safety of others, they should be informed to take safety measures. Before hot work, the person in charge of hot work should formulate emergency measures, prepare fire monitoring and fire extinguishing equipment, and use designated special fire extinguishers for all fires. If you need other fire extinguishers, you need to ask for permission. Hot tools must be in good condition, complete safety measures and meet safety requirements. The distance between oxygen cylinder and acetylene cylinder should be greater than10m, and the distance between acetylene cylinder and oxygen cylinder should be greater than 7m. If an accident occurs in violation of regulations, the hot work personnel shall be responsible. Underground wells, trenches, cable trenches and drainage ditches near hot work should be cleared of flammable and explosive substances or closed and isolated, and outdoor aerial work is not allowed in strong winds above level 5. The welding return route shall be connected to the weldment. If it cannot be directly connected to the weldment, the distance of the return route should be shortened as much as possible. Hot work should be stopped in case of emergency such as running, running, dripping and leaking flammable substances during hot work. Return to normal, and should be approved before continuing hot work. During indoor hot work, doors and windows should be opened and surrounding equipment should be covered. There are no inflammable substances with strong volatility nearby, which are used for production or open storage, scrubbing equipment, etc. At the same time, inflammable and explosive articles are not allowed to pass through the hot work site during hot work. When one workshop is hot, the adjacent workshops should take corresponding protective measures to prevent the fire from spreading. Unless there are special circumstances, it is forbidden to bring materials, take pressure and use fire. After the hot work, the electric welding personnel should extinguish the residual fire, cut off the power supply of the electric welding machine, turn off the acetylene and oxygen generators, and check the safety before leaving. Acetylene bottles and oxygen cylinders must be stored in accordance with regulations. After hot work, the fire supervisor should put the fire equipment back in its original place, and the person in charge of hot work should arrange a comprehensive inspection (water cleaning) on the hot work site to prevent accidents. The safety officer has the right to supervise the implementation of safety measures. During hot work, the person in charge of hot work shall not leave the post of fire supervision from beginning to end. When it is necessary to leave the post under special circumstances, the person in charge of hot work must appoint an agent.
