Precautions For Storage And Safe Use Of Gas Cylinder Cabinets

Oct 12, 2018

(1) Gas cylinder cabinets must be stored in a cool, dry, open fire-proof room away from heat sources, and open flames and anti-exposure (see section 1 for requirements). Except for non-combustible gases, they are not allowed to enter the laboratory building. The cylinder in use should be erected on a special bracket.

(2) Handle the gas cylinder cabinet gently to prevent falling, knocking, rolling or severe vibration. Wear a safety helmet before moving to prevent accidental breakage of the bottle mouth. The cylinder must have two rubber shock rings. The acetylene bottle is strictly prohibited from rolling horizontally.

(3) Gas cylinder cabinets shall be regularly subjected to technical inspection and pressure test according to regulations.

(4) Gas cylinders that are prone to polymerization, such as ethylene, acetylene, etc., should be used within the storage period.

(5) The pressure reducer of the high-pressure gas cylinder should be used exclusively. When installing, the screw buckle should be tightened (should be screwed into 7-thread thread, commonly known as eating seven teeth), and no air leakage is allowed. When opening the high pressure gas cylinder, the operator should stand on the side of the gas cylinder outlet and move slowly to reduce airflow friction and prevent static electricity.

(6) Oxygen cylinders and their special tools are strictly prohibited from contact with oil. Oxygen cylinders must not have oil.

(7) The distance between the oxygen cylinder, the flammable gas cylinder and the open flame shall not be less than 10m. When it cannot be reached, there shall be reliable thermal insulation protection measures, and shall not be less than 5m.

(8) The gas in the cylinder bottle should not be exhausted. Generally, the residual pressure of 0.2?1 MPa should be maintained. The aeration unit should be used for inspection and sampling and prevent other gas from being poured.
