Oxygen and fuel gas cylinders should be stored at least 20 feet apart or separated by a fire-resistant barrier
Oxygen and fuel gas cylinders are highly combustible and require careful storage to prevent fires and explosions. When stored, oxygen and fuel gas cylinders should be kept at least 20 feet (6.1 m) apart, or they should be separated by a non-combustible barrier that is at least 5 feet (1.5 m) high with a fire-resistance rating of at least half an hour. This rule applies to both indoor and outdoor storage.
Oxygen cylinders should be kept away from combustible materials, especially oil and grease, and other substances that can cause or accelerate a fire. This includes acetylene and other fuel gas cylinders, as well as calcium carbide. Oxygen cylinders should also not be stored near any open flames or sources of artificial heat, such as hot metal. If oxygen cylinders are stored in an outdoor generator house, they must be separated from the generator and carbide storage room by a non-combustible barrier with a fire-resistance rating of at least one hour, with no openings.
Fuel gas cylinders should be placed with the valve end up when in use and should not be placed in cabinets. They should be stored away from any sources of flame, heat, or sparks, and the area should be well-ventilated. When security is a concern, a screened cage can be used to contain the cylinders, but at least two sides of the cage must be at least 80% open to allow for airflow.
In addition to separation distance and barriers, there are other important considerations for the safe storage of oxygen and fuel gas cylinders. Compressed gas containers and systems should be secured and protected against physical damage and tampering. The storage area should be well-drained, with a concrete or other non-combustible platform. The temperature of the storage area should not exceed 125°F (51.7°C), and there should be "no smoking" signs displayed.
It is important to note that these are general guidelines, and specific regulations may vary depending on the jurisdiction and the specific gases being stored. Employers must develop and implement safe operating procedures for the handling and storage of compressed gas cylinders, prepared by a safety technical specialist and based on the hazards of the gases present.

Cylinders should be stored in a well-ventilated, dry location, away from combustible materials
When storing oxygen and fuel gas cylinders, it is important to follow strict safety protocols to prevent accidents and fires. Cylinders should be stored in a well-ventilated, dry location, away from combustible materials. This is because oxygen is a highly reactive gas that can easily ignite flammable materials and cause an explosion.
Oxygen cylinders must be kept away from combustible materials, especially oil and grease. Oil and grease are highly flammable and can easily ignite in the presence of oxygen, leading to a violent explosion. To prevent this, it is crucial to maintain a minimum distance of 20 feet (6.1 m) between oxygen cylinders and combustible materials or separate them using a non-combustible barrier that is at least 5 feet (1.5 m) high and has a fire-resistance rating of at least one-half hour.
Additionally, oxygen cylinders should not be stored near other fuel-gas cylinders or substances that can cause or accelerate fires, such as acetylene, calcium carbide, or other flammable materials. Storing oxygen cylinders near these substances increases the risk of fire or explosion, as oxygen can enhance the combustion process. Therefore, it is essential to keep oxygen cylinders separated from other flammable gases and materials to minimize the risk of accidents.
The storage area for oxygen and fuel-gas cylinders should be well-ventilated to prevent the buildup of gases, which could lead to an explosion if ignited. Well-ventilated areas allow for proper airflow, reducing the concentration of gases and decreasing the risk of accidental ignition. This is particularly important in enclosed spaces where gases can accumulate and pose a greater risk of explosion.
Furthermore, when storing oxygen and fuel-gas cylinders, it is crucial to choose a dry location. Moisture can accumulate and cause corrosion, weakening the cylinders and potentially leading to leaks. A dry storage area helps maintain the integrity of the cylinders and reduces the risk of accidents. Additionally, keeping the cylinders in a secure location, such as a designated room or a fenced area, can prevent unauthorized access and tampering, ensuring that the cylinders are used and handled safely.

Cylinders should not be stored in cabinets
Gas cylinders should be stored in a well-ventilated area, away from direct sunlight and heat sources. They should be placed in a designated, secure, and dry location, separate from flammable and combustible materials. Cylinders should be stored upright, with valves closed and protected by caps or specific devices, and secured with chains or straps to prevent damage and corrosion.
Cylinders should be easily accessible and visible in their storage area. Storing them in cabinets can hinder accessibility and make it challenging to identify leaks or damage promptly. It is crucial to inspect cylinders regularly and ensure they are secure and in good condition. Restricted access could delay the detection of potential issues.
Furthermore, cabinets may not meet the required distance regulations for separating oxygen and fuel gas cylinders. It is essential to maintain a minimum distance of 20 feet (6.1 meters) between oxygen and fuel gas cylinders or separate them with a non-combustible barrier at least 5 feet (1.5 meters) high with a minimum fire resistance rating. Cabinets may not provide the necessary separation, increasing the risk of accidents.
Storing cylinders in cabinets can also make it challenging to comply with regulations requiring cylinders to be stored away from elevators, stairs, emergency exits, and electrical wiring. Cabinets may hinder the ability to maintain the required distances and could increase the risk of accidents or unauthorized access. Therefore, it is crucial to follow storage guidelines to ensure the safe handling and storage of gas cylinders.

Oxygen cylinders should be stored away from fuel gas cylinders, especially acetylene
Oxygen and fuel gas cylinders should be stored carefully, with certain precautions in place, to prevent accidents and fires. Mixtures of fuel gases and oxygen may be explosive and must be avoided. Oxygen cylinders must be kept away from highly combustible materials, especially oil and grease. They should also not be stored near acetylene or other fuel gas cylinders, or near any other substance likely to cause or accelerate a fire.
Oxygen cylinders should be stored at least 20 feet (6.1 m) away from fuel gas cylinders, or separated by a non-combustible barrier at least 5 feet (1.5 m) high with a fire-resistance rating of at least half an hour. This barrier must be impervious to gases and made of non-combustible materials. This is because oxygen and acetylene are both extremely volatile and dangerously reactive gases. Acetylene is a Class 2.1 Flammable Gas and can react dangerously with oxidising agents, causing explosions.
Acetylene cylinders must be stored with the valve end up and must be handled with extreme care. The main risk associated with acetylene cylinders is a dangerous chemical reaction known as decomposition, which gives out a lot of heat and can cause spontaneous fires and explosions. This can be caused by exposure to heat, sunlight, hot works, industrial plant and machinery, or rough handling.
It is important to follow safety guidelines when storing oxygen and fuel gas cylinders, to prevent accidents and fires. In addition to the above, it is recommended that cylinders are stored in a well-ventilated, dry location, away from elevators, stairs, or gangways, and where they will not be knocked over or damaged by passing or falling objects.
