Dual firing inflator for an inflatable article. A first gas containing capsule is pierced by energy supplied either manually or by a compressed spring of the like and the gas from the pierced first capsule powers a second piercing pin which pierces a second gas containing capsule. This reduces the amount of externally applied energy which is necessary to operate the inflator while supplying the inflatable article with an amount of gas which is twice that contained in capsules which are normally used with inflators of the same general type.
