A rupture disk system has a housing defining a central axis, a first axial end defining an axial opening and a second axial end. An airflow pathway extends from the first axial end facing towards the second axial end. A sealing surface is defined about the airflow pathway towards the first axial end. A shield extends across the airflow pathway on the second axial end. Radial openings are defined around the central axis, where the radial openings are positioned between the first and the second axial ends, such that the airflow pathway extends from the axial opening to the radial openings. A rupture disk is coupled to the housing across the airflow pathway. The rupture disk has a polymeric layer. The rupture disk has an unweakened region having a first thickness and a weakened region having a second thickness. A threshold rupture pressure is defined by the weakened region.

The dash bridge and hook rescue device is a two piece emergency rescue tool utilized in the extraction of accident victims from underneath a dashboard and steering column as the result of an automobile accident where severe injuries are incurred by the victim. The rescue device is used to expedite the lifting and removal of the steering column and dashboard using existing winches, power spreaders or extension ram devices, either manual, air or hydraulic powered, to engage the hook attached below the steering column and lift it from the dash bridge spanning from the hood of the car to the roof of the car, bridging the windshield through which the hook extends, and lifting the steering wheel in a vertical direction off the lap and chest of the victim. Unrestricted access to the victim from the passenger compartment of the vehicle and transfer to emergency transport vehicles for critical care is expedited over other existing emergency extraction device techniques.

A multiple component wrench is adapted for use to attach and disconnect fire hose and hydrant coupling using this singular tool in lieu of several tools currently used by firefighters. The wrench has a sliding portion and a receiver portion presented as one tool, yet allowing multiple wrenches adapted for use on Storz and spanner hose couplings, rocker lug couplings, water meter shutoff valves, gas cock valves, pentagonal nuts and square nuts, and includes a multiple ratchet mechanism with multiple removable ratchets adapted to a variety of different nuts encountered on the multiple hydrants installed in various municipalities. The wrench is also extendable to provide additional leverage during use, the wrench further capable of separation forming two independent wrenches.

The B-post extension device is a movable support base utilized in emergency rescue situations involving automobiles, specifically door openings, the device providing for an adjustable support base for an extension ram, the device being placed against a support structure within the automobile, the device further having an adjustable slide plate secured upon at least two support rod arms, the support rod arms spanning a distance between a heel portion and a toe portion, the toe and heel portion resting against the automobile support structure, reducing the distance required to be pushed by the extension ram and providing readjustment for the increasing span of the door opening during extension and recovery of the extension ram.
