Methods and apparatus for a dual stage hazard suppression system according to various aspects of the present invention include a housing containing a first hazard control material that is configured to be located close to a hazard source and a container containing a second hazard control material located at a distance from the hazard source. The housing may be configured to release the first hazard control material in response to a breach of the housing and/or the hazard source. The container may be configured for a timed release of the second hazard control material in response to the release of the first hazard control material. Alternatively, a sensor may be used to trigger the release of the second hazard control material in response to a triggering event separate from the initial breach of the housing and/or the hazard source.
