1 Purpose: To ensure the safety of CO2 cylinders during storage, transportation, loading, unloading and use, this management procedure has been developed. <br>2 Scope of application: Relevant departments and personnel involved in the storage, transportation, loading, unloading and use of CO2 cylinders. <br>3 Reference materials: None <br>4 Definition: None <br>5 Main tools / appliances used: Omitted <br>6 Content: <br>6.1 CO2 cylinders are special containers. It is strictly forbidden to use CO2 gas cylinders to fill other gases, or to use other gas cylinders to fill CO2 gas. <br>6.2 The CO2 gas in steel cylinders is a high-pressure liquefied gas, and its filling factor should not be greater than 0.6 kg / l; we use a steel cylinder with a nominal volume of 46 liters and a nominal working pressure of 15 MPa, that is, the weight of the filled CO2 gas should be less than 27.6 kg ( According to need, the weight of the filled CO2 gas is 25 ~ 27.5kg). <br>6.3 During storage and transportation of CO2 steel cylinders, the caps should be screwed on. During the process of loading, unloading and transportation, they should be handled lightly, and throwing, sliding, rolling and touching are strictly prohibited. <br>6.4 The transportation of CO2 cylinders in summer should be equipped with shading equipment to avoid exposure, and it is strictly forbidden to park in high temperature areas. <br>6.5 The empty and solid bottles of CO2 steel cylinders should be placed separately and have obvious signs; they should be placed securely. When lying, the head orientation should be uniform. When stacking, the sides should be tight. The stacking height is strictly prohibited to exceed five layers; when standing Should prevent shaking and dumping. <br>6.6 CO2 steel cylinders should be installed and removed in a stable manner, and should be steadily and gently dropped to avoid crushing and crushing hands and feet. The connection between the hose and the cylinder release valve should be tight and reliable, and gaskets must be added between the joints. <br>6.7 After the installation of the bottle set, the guard bar should be put on, check the weight balance system of the adjustment release valve, check whether the valve opening and closing of the pipeline system is correct, and ensure that the CO2 gas release and injection are flexible and accurate. <br>6.8 The equipment department should have special personnel to regularly check the leakage of steel cylinders and gas valves. Any leakage of the cylinder valve or the replacement of the cylinder valve due to thread damage should be marked with a strict mark. Tighten the gas valve with special equipment at the inflation station, otherwise it is strictly forbidden to use it. .<br>6.9 The release valve after maintenance shall be tested for leakage with high-pressure oxygen. If the pressure does not leak when the pressure is greater than 12MPa, the valve can be sent to the inflation station for valve inflation. <br>6.10 After the erupted empty bottle is unloaded, the equipment department should appoint a special person to check the integrity of the release valve; do not close the valve for the empty bottle to be inflated, and then close the valve and screw on the bottle cap when loading the vehicle to prevent mixing. <br>6.11 The steel stamp and color mark on the bottle must not be changed at will. CO2 cylinders should be submitted for inspection every three years according to the regulations; if severe rust, damage or doubts about their safety and reliability are found during use, they should be submitted for inspection in advance. <br>7 Record / Form: None <br>8 Work flow chart: None
