A gas generator ( 10 ) is provided, comprising an initiator ( 48 ) including an initiator charge, a gas generant insert ( 52 ) spaced apart from the initiator ( 48 ), and a fluid-impermeable blast director ( 42 ) interposed between the initiator ( 48 ) and the gas generant insert ( 52 ). The blast director ( 42 ) provides a barrier between the gas generant insert ( 52 ) and a blast resulting from ignition of the initiator charge when the initiator charge is ignited. The blast director ( 42 ), when used with particular gas generant configurations, reduces the effects of the initiator blast and reduces the amount of gas generant exposed to the blast, enabling the structural integrity of the gas generant ( 52 ) to be maintained.
