What are the standard requirements for how to store gas cylinders?

The storage of gas cylinders involves a number of safety standards and requirements to ensure the safety of personnel and facilities. These requirements may vary from country to country, but generally include the following aspects:

1. Selection and layout of storage areas
Away from heat sources and direct sunlight: Avoid high temperatures that may cause the pressure of gas cylinders to increase.

Good ventilation: Ensure that any leaking gas can be quickly dispersed to reduce potential hazards.

Away from flammable materials and potential ignition sources: Avoid the risk of fire and explosion.

Clearly marked: Clearly mark the storage area and indicate the type of gas stored.

2. Storage method
Store vertically: Most gas cylinders should be stored vertically and secured with chains or stable racks to prevent them from falling.

Separate different types of gases: Combustible gases should be stored separately from oxygen or other combustion-supporting gases, usually requiring a certain physical distance or using a firewall.

Avoid ground moisture: Use pallets or racks to keep gas cylinders away from the ground to avoid corrosion due to ground moisture.

3. Inspection and maintenance of gas cylinders
Regular inspection: Check the integrity, leakage, expiration and corrosion of gas cylinders and valves regularly.

Clear labeling: Mark the contents of gas cylinders, filling date and next inspection date.

4. Safety measures
Appropriate personal protective equipment: Ensure that operators wear appropriate personal protective equipment (PPE) when handling and using gas cylinders.

Training: Ensure that all personnel involved in the handling, use and storage of gas cylinders receive appropriate training.

Standards and regulations
Different countries and regions may have specific standards and regulations for gas cylinder storage, for example:

USA: The Occupational Safety and Health Administration (OSHA) and the National Fire Protection Association (NFPA) provide guidance and standards related to the storage and operation of gas cylinders.

EU: Europe has relevant standards and guidelines, such as the EN standard series.

China: The Chinese National Standard (GB) also covers relevant requirements, such as "Combustible Gas Cylinders" (GB 5099).
