Abstract
A gas purification system includes a gas purification unit and one or more safety devices. The gas purification unit includes an enclosure containing a purification material that exhibits an exothermic reaction when exposed to certain gas contaminants. The gas purification unit also has an inlet coupled to an unpurified gas inlet line and an outlet coupled to a purified gas outlet line. A safety device can be coupled either to the unpurified gas input line or the purified output line, or both, and develops an alarm signal when gas contaminants exceed a given concentration level for a period of time.
