Oxygen Cylinder Storage Requirements Osha

Osha requires that gas cylinders in workplaces have specific labeling that explains the type of gas in the cylinder.

Oxygen cylinder storage requirements osha.

D oxygen cylinders in storage shall be separated from fuel gas cylinders or combustible materials especially oil or grease a minimum distance of 20 feet or by a non combustible barrier at least 5 feet high or a minimum of 18 inches 46 centimeters above the tallest cylinder and having a fire resistance rating of at least one hour. Medical gas cylinder storage. Pure oxygen and acetylene are both extremely volatile and dangerously reactive gases. Or empty cylinder rather than a full one.

Nfpa 99 1999 has very specific requirements for storage of nonflammable medical gases exceeding 3 000 cu. Special storage use and handling precautions are necessary in order to control these hazards. An aggregate total of compressed medical gases e g oxygen nitrogen nitrous oxide up to 300 cubic feet may be stored per smoke compartment in any room or alcove without special requirements for that room. The hazards associated with these gases include oxygen displacement explosion hazards toxic effects and the physical hazards of a ruptured cylinder.

The greater the volume the more stringent the requirements for the storage locations. For example workers could label a cylinder that contains oxygen as either o2 or oxygen gas. Up to 20 000 cu. Compressed gas cylinders must be secured in racks or by chains.

Gas cylinder storage requirements for the storage of medical gas cylinders depends on the volume of gas within the cylinders. Employees can mark the cylinders with either the trade name of the gas or the chemical name of the gas. Volumes greater than 3000 ft3. Hazards associated with compressed gases include oxygen displacement fires explosions and toxic gas exposures as well as the physical hazards associated with high pressure systems.

Where a liquid oxygen system is to be used to supply gaseous oxygen for welding or cutting and the system has a storage capacity of more than 13 000 cubic feet 364 m 3 of oxygen measured at 14 7 psia 101 kpa and 70 f 21 1 c connected in service or ready for service or more than 25 000 cubic feet 700 m 3 of oxygen measured at 14. Ft including providing 1 hour fire rated room construction ventilation and explosion proof electrical fixtures such as motors and lights. This volume of gas must be stored in locations that include the following.
