Helium cylinders should be stored in an indoor, well-ventilated, secure area. The cylinders should not be stored in areas that are unprotected from the weather. Exposure to wet or damp areas could result in rusting, weakening the metal which could cause the cylinder to burst. The cylinder should be stored upright, to prevent damage to the nozzle or valve. The temperature of the storage area should not exceed 120˚F (49˚C). The storage area should not have any materials in it that are combustible.
Do not store the helium cylinder:
- where salt or other corrosive materials are present.
- in your vehicle for any extended period of time.
- in high-traffic areas or emergency exits, where the cylinder could be tripped over or knocked down, resulting in damage to the cylinder, injury, or release of the helium.
