Mine Safety

ExtendAir® products are used in mine safety equipment such as SCSR`s, escape hoods and to control CO2 in safety shelters. Lithium Hydroxide is typically used for its ability to absorb CO2 passively as well as in active, powered systems. Mine rescue rebreathers such as the Biomarine BioPak 240 use calcium hydroxide cartridges.

ExtendAir absorbent curtains can be used to absorb CO2 without needing power in any confined space by hanging groups of curtains in the occupied area.
