Building and Fire Codes limit the volume and types of gases permitted in buildings. S tore full and empty cylinders only in isolated areas that are ventilated and protected from direct sunlight, rain, snow, damp ground, heat, fire and electrical contact. Temperatures in storage should be maintained between -20 o and 125 o F. Never store or use cylinders in corridors or stairwells, or near exits or doorways. This includes cryogenic dewars such as liquid nitrogen. C hain or strap all cylinders to a sturdy object, as a wall, bench, stand, or in a specially designed cylinder pen.
Cylinders can become missiles if damaged.
Do not secure cylinders to water, gas or other utilities. Store and use cylinders in an upright position or as manufacturers recommend. Separate oxidizer gases from flammables and combustibles by at least 20 feet of space, or a one hour fire-rated wall. H ighly toxic, flammable, and reactive gases require extensive engineering controls such as special ventilation and building construction, approved enclosures, alarms, fire protection, detectors, restricted flow orifices and other safety features. Fire codes do not permit certain high hazard gases in many of our campus facilities .
