A flexible heat barrier is configured to absorb and deflect heat energy and utilizes a multilayer construction wherein each layer provides a specific purpose. An outer layer configured for exposure to a heat flux includes a coating having an intumescent component and an opacifier component. An inner layer includes a foil that may include a high emittance coating to more effectively reflect radiation. A middle layer includes a insulating fabric layer that may include oriented fibers that can effectively polarize radiation and may include a plurality of layers of oriented fibers that are configured at an offset angle to deflect and reduce radiation transmission through the middle layer. A flexible heat barrier may also include a flexible gas barrier that includes a phase change material, such as frits that melt at a predetermined temperature and flow into gaps to reduce the permeability and further block heat flux.

A fire blanket deployment system includes a fire blanket assembly including a foldable fire blanket that is detachably coupled to a carrier. The foldable fire blanket is initially in a folded state. The system can include a frame having a plurality of vertical supports that are spaced apart from one another and for placement about an asset to be protected. A first suspension system is coupled to the plurality of vertical supports and is configured to move the fire blanket assembly to a target location between the plurality of vertical supports. A second suspension system that is coupled to the plurality of vertical supports and is configured to controllably unfold the fire blanket once the fire blanket assembly in at the target location. The second suspension system has an automatic detachment mechanism that allows the unfolded fire blanket to move downward toward the asset to be protected.

The present disclosure relates to a barrier system for shielding humans from harmful exposure to fire, smoke, noxious fumes, or contaminated air. Some embodiments provide a deployable barrier system that has a barrier retract assist system configured to assist a user in manually moving the barrier from the deployed position toward the retracted position with at least a portion of the barrier being rolled onto the barrel portion for egress past the barrier. The retract assist system can be positioned inside of the barrel portion.
