Hydrogen bottle storage standard

Hydrogen and empty bottles should be stored separately in the compartment at the edge of the unit and away from open flames or equipment with operating temperatures equal to or higher than the ignition point.

The hydrogen cylinder should be light green according to GB 7144, and the 20 MPa cylinder should have a light yellow color ring, and the red paint should be coated with the word “hydrogen” and the name of the filling unit. The paint color and the words should be kept clear.

Hydrogen bottles are used in multi-storey buildings. In addition to special needs for production, it is generally preferred to use hydrogen bottles in indoor (on-site) for the production needs of the top outer wall. The number of air bottles should not exceed 5 bottles. The indoor (site) ventilation conditions are 4.1. .5 requirements, and arrangements meet the following requirements:

a) The distance between the hydrogen cylinder and the vessel and cylinder containing flammable, explosive, combustible and oxidizing gases shall not be less than 8 m;

b) the distance from open flame or ordinary electrical equipment shall not be less than 10 m;

c) the distance from the air inlets such as air conditioning units, air compressors and ventilation equipment (non-explosion proof) shall not be less than 20 m;

d) The distance from other flammable gas storage locations should not be less than 20 m.

Hydrogen bottle bodies shall be provided with bottle caps (except gas cylinders with protective cover) and anti-vibration rings (except for assembled gas cylinders) during transportation to prevent damage to the valve.

The ammonia cylinder should be handled gently and gently, and must not be thrown. It is strictly prohibited to impact and strong vibration. Do not roll down from the car. The hydrogen bottle should be strictly fixed during transportation.

Sites where hydrogen bottles are stored and used should be well ventilated. Do not get close to fire, heat and exposure to the sun. Do not store in the same warehouse with chemicals such as strong acids, alkalis and oxidizing agents. Hydrogen cylinders should be stored separately from oxygen cylinders, chlorine cylinders, and fluorine gas cylinders.

Do not use up the gas in the cylinder. Keep at least 0.05 MPa of pressure in the bottle to prevent air from entering the cylinder.

According to the “Cylinder Safety Supervision Regulations”, hydrogen cylinders should be inspected regularly (every 3 years), and the cylinders should have inspection stamps and inspection color standards.

The gas cylinder assembly device shall have protective devices to prevent the pipeline and the valve from colliding; the gas cylinders, pipelines, valves and joints shall be frequently maintained and maintained, and shall not be loosely displaced or leaked.
