Legal analysis: acetylene cylinder in use, transportation, storage, the ambient temperature shall not exceed 40 ℃. Acetylene cylinder paint color must remain intact, shall not be arbitrarily altered. Acetylene cylinders in use must be equipped with special pressure reducer. Flashback preventer, must check whether it is good to use before work, otherwise it is prohibited to use, when opening, the operator should stand behind the side of the valve, the action should be gentle. The use of pressure does not exceed 0.05Mpa gas delivery flow should not exceed 1.5-2.0 meters 3 / hour bottle. Pay attention to the use of fixed, to prevent tipping, is strictly prohibited lying into the use of acetylene bottles that have been lying into, not allowed to directly open the gas to use, the use of the first must first stand firm after fifteen minutes of static, and then connected to the regulator to use, otherwise dangerous. Prohibit knocking, collision and other rough behavior. Cylinders shall not be close to the heat source and electrical equipment, summer sunshade measures to prevent sun exposure, and the distance from the open fire should be greater than 10 meters (when working at height is the parallel distance from the vertical ground). When the bottle valve freezes, it is forbidden to bake it with fire, and it can be thawed with warm water below 10℃. When the workplace is frequently moved, it should be mounted on a special trolley, and acetylene and oxygen cylinders should be avoided to be put together. Strictly prohibit copper, silver, mercury and other products and acetylene contact, and acetylene contact with copper alloy appliances must be higher than 70% copper content. The use of acetylene cylinder gas shall not be exhausted, the remaining pressure should meet the safety requirements: when the ambient temperature <0 ℃, the pressure should not be less than 0.05MPa; when the ambient temperature of 25 ~ 40 ℃, it should not be less than 0.3MPa.
Legal basis: According to the "Dissolved Acetylene Cylinders Safety Supervision Regulations," Article 58 provides that: acetylene cylinder transportation, storage and use, must be Strictly implement the State Council issued the "Regulations on the Safe Management of Chemical Dangerous Goods" of the relevant provisions. According to the "dissolved acetylene cylinder safety supervision regulations" Article 59: transport, storage and use of acetylene cylinders must strengthen the transportation, storage and use of acetylene cylinder safety management, and do: 1. a full-time staff responsible for the safety of acetylene cylinders; 2. according to the relevant provisions of the regulations, the development of the appropriate safety management system; 3. the development of emergency response to accidents; 4. regularly on the transportation of acetylene cylinder (including loading and unloading, escort, driving), storage and use of personnel for safety and technical education and practical training.
