Compressed gas cylinder safety training is for lab staff, researchers, medical facility workers and factory employees who handle gas cylinders. Maintenance technicians who store or connect cylinders need it too, as does anyone working with cryogenic liquids. The 14-minute video is in English, with Spanish and French closed captions.

Compressed gas cylinders are covered by OSHA 29 CFR 1910.101. That section requires cylinder inspection and handling, storage and use in line with Compressed Gas Association pamphlets. Under 29 CFR 1910.253, stored oxygen cylinders must be kept 20 feet from fuel gas cylinders and combustibles or separated by a fire-resistant barrier.

Compressed gas cylinders should be stored upright and secured with chains or straps so they cannot fall. Keep valve caps on when cylinders are not in use. Store them in a cool, dry, ventilated area away from heat sources, and separate incompatible gases such as oxygen and flammables. Mark empty cylinders clearly.

Compressed gas cylinders are dangerous because of both their contents and their pressure. Gases may be flammable, toxic, oxidizing or corrosive, and some carry several hazards at once. A cylinder with a broken valve can rocket across a room, and leaking inert gases can displace oxygen and cause asphyxiation.

Cryogenic liquids are gases chilled until they become liquid at extremely low temperatures, while other compressed gases are held under pressure at normal temperatures. Cryogens cause cold burns and frostbite on contact, and refreezing can block valves and build pressure. Wear face shields, goggles and leather gloves when handling them.
