US 8,505,642 B2 · Methods and apparatus for dual stage hazard control system

Abstract

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.

Dependent claims

A dual-stage fire suppressant system for protecting against instantaneous and slow growth fires resulting from a breach of a potential fire source during a transient event, comprising:

a first fire suppressant system, comprising:
a first fire suppressant;
and
a housing configured to at least partially enclose the potential fire source, comprising:
a first wall;
and
a second wall connected to the first wall and defining an inner volume;
and wherein the housing is configured to:
contain the first fire suppressant within the inner volume under a first pressure;
and
release the first fire suppressant in response to the breach of the potential fire source and the housing during the transient event;
a second fire suppressant system responsively linked to the first fire suppressant system, comprising:
a second fire suppressant;
and
a container positioned away from the housing and configured to contain the second fire suppressant under a second pressure;
and
a distribution system connected to the container, wherein the distribution system is adapted to:
provide a signal to the second fire suppressant system in response to a predetermined event, wherein the signal causes the second fire suppressant system to release the second fire suppressant;
and
route the released second fire suppressant from the container to the housing.

17 more elements

A dual-stage hazard control system for a hazard source which may be released during a transient event causing a breach in the hazard source, comprising:

a first hazard control agent;
a second hazard control agent;
a first hazard control system configured to at least partially enclose the potential fire source, wherein the first hazard control system:
is responsive to the transient event and configured to contain the first hazard control agent;
and
is configured to deliver the first hazard control agent to the hazard source substantially simultaneously with the occurrence of the transient event;
and
a second hazard control system linked to the first hazard control system, wherein the second hazard control system is configured to:
contain the second hazard control agent;
and
release the second hazard control agent over a predetermined period of time after the first hazard control agent has been delivered in response to an activation signal;
and
a sensor proximate to the first hazard control system, wherein the sensor is configured to generate the activation signal in response to a detected event following the transient event.
