A portable fire extinguisher is disclosed which includes a cylinder for storing a pressurized fire extinguishing agent and has a neck portion defining an outlet, and a flexible hermetic seal supported across the outlet of the cylinder, wherein the flexible hermetic seal is adapted and configured to transition between: an unexpanded condition corresponding to an unpressurized cylinder; an expanded condition corresponding to a pressurized cylinder; and a bursted condition corresponding to an opened cylinder.

Hermetically sealed portable fire extinguisher with pressure indicator

An escape ladder provides emergency egress from a dwelling and generally comprises a hook assembly connected to a ladder assembly. The hook assembly includes a pair of laterally spaced clamps and the ladder assembly includes a pair of straps attached to the clamps and a series of rungs extending between the straps. Each clamp comprises an upper hook and a lower hook connected via a hinge. The pair of clamps are connected via a collapsible stabilizer bar. The hinges and stabilizer bar permit the clamps of the hook assembly to be folded and compressed to form an un-deployed configuration of the hook assembly. The rungs are of common cross-sectional shape permitting them to be nested in an un-deployed configuration of the ladder assembly. The escape ladder of the present invention provides secure attachment to the dwelling, folds into an un-deployed package that small and compact for storage, yet is assembled to provide user-friendly deployment that can be reliably deployed in a high stress situation.
