Compressed Gases G ases present more severe hazards than materials in the solid and liquid states.
Gases have generally higher reactivities, and more rapid diffusion capabilities.
Even non-toxic gases can kill by asphyxiation. In addition, compressed gas cylinders are physical hazards due to their high pressure. 10.13.1 Storage K eep only those gas cylinders in the lab or work area that are being used. Building and Fire Codes limit the volume and types of gases permitted in buildings.
