Carbon dioxide

Conditions for safe storage, including any incompatibilities: Keep container tightly closed in a dry and well-ventilated place. Contents under pressure. Avoid heating above: 50 deg C.

Fireproof if in building. Cool. Ventilation along the floor.

Dry ice should not be kept in container that is not designed to withstand pressure. Containers of other substances stored over dry ice for extended periods generally absorb carbon dioxide unless they have been carefully sealed. When such containers are removed from storage and allowed to come rapidly to room temperature, the carbon dioxide may develop sufficient pressure to burst the container with explosive violence. On removal of such containers from storage, the stopper should be loosened or the container itself should be wrapped in towels and kept behind a shield.

Store liquid containers in well ventilated areas. Keep cylinders away from sources of heat. Storage should not be in heavy traffic areas to prevent accidental knocking over or damage from passing or falling objects. Valve caps should remain on cylinders not connected for use. Segregate full and empty cylinders. ... Store carbon dioxide cylinders with the valve end up.
