(1) The cylinder should be placed in a cool place, away from power and heat sources (such as sunlight, heating, fire, etc.), and be fixed. Combustible gas cylinders must be stored separately from oxygen cylinders.

(2) When handling cylinders, wear bottle caps and rubber waist rings. Be gentle and do not roll on the ground to avoid collisions and sudden falls.

(3) High-pressure cylinders must be installed with a pressure relief valve before use. Generally, the thread of the valve on the combustible gas cylinder is reverse buckle (such as hydrogen and acetylene), and the non-combustible or combustion-supporting gas cylinder (such as N2 and O2) is positive wire. All kinds of pressure reducing valves must not be mixed.

(4) When opening and closing the valve, the operator should avoid the direction of the bottle mouth and stand on the side to prevent the injury and slow operation in case the valve or pressure gauge is rushed out.

(5) The nozzle and pressure reducing valve of oxygen cylinder are strictly prohibited from fouling grease. When opening the oxygen cylinder, special attention should be paid to not have grease on the hands and tools. The oil on the wrench should be washed off with alcohol and used after drying to prevent combustion and explosion.

(6) Oxygen cylinders and hydrogen cylinders are strictly forbidden to be used in the same laboratory.

(7) The gas in the cylinder cannot be completely exhausted, and the residual pressure above the gauge pressure of 0.05MPa should be maintained to prevent the danger of re-filling.

(8) Cylinders shall be sent for inspection regularly before qualified cylinders can be used by inflating.
