Catalina Cylinders recommends that anyone storing CO2 cylinders should be aware of the hazards associated with CO2 and be trained in safe practices of storing CO2 cylinders. All practices of storing CO2 cylinders ought to include or reference information from CGA pamphlets G-6; Carbon Dioxide and G-6.3; Carbon Dioxide Cylinder Filling and Handling Procedures. Catalina Cylinders has compiled the following list of items that should be included in any safe storage practice of CO2 cylinders.
- CO2 cylinders should always be stored in a specified area. The storage area should:
- Be well ventilated. CO2 gas in small concentrations, as little as 15%, can cause unconsciousness in less than one minute.
- Be selected away from the edge of any elevated areas. Cylinders falling from elevated areas can cause damage to the cylinder, valve or property or injury to personnel.
- Be selected away from, or protected from, areas of high traffic. Areas of high traffic only increase the chance of an accident occurring.
- Be dry and free of a corrosive atmosphere.
- Have adequate means to secure all cylinders stored in the area. The means of securing should be sufficient to hold the cylinders in place, yet not cause damage to the cylinders.
- Be a continuously cool place. Do not store cylinders adjacent to any source of heat, intermittent or continuous. Safety relief devices of CO2 cylinders are designed to operate when the pressure of the cylinder exceeds 2800 – 3000 psi (depending on the design of the safety relief device). A properly charged CO2 cylinder could vent through it’s safety relief device at approximately 150 oF (65.6 oC). A slightly overfilled CO2 cylinder could vent through its safety relief device when exposed to a much lower temperature. The CGA recommends that CO2 cylinders be stored in areas with a temperature less than 125 oF (51.7 oC).
Including the above items in all practices for storing CO2 cylinders should enhance the safety of all personnel, equipment and property.
