A shear blade is for a portable hydraulic cutting device having a blade body. The blade body has assembly and cutting regions, with a cutting edge in the cutting region. A contact surface is on one side of the cutting edge for an additional shear blade. An outer surface on the other side of the cutting edge acts on the object to be cut. A first surface portion of the outer surface extends away from the cutting edge along an orthogonal, which meets the contact surface at the cutting edge, or at an acute angle relative to the orthogonal. A second surface portion connects to the first surface portion at an acute angle to the orthogonal. A third surface portion connects to the second surface portion at an acute angle to the orthogonal. Angle is smaller than angle , which is smaller than angle .

A one-way clutch is provided at the end of the rotary shaft of the hydraulic pump, which can receive the rotary shaft of the drive unit. The one-way clutch has spring-urged rollers, balls or sprags, which are urged by springs, and which are brought into direct contact with the drive shaft of the drive unit when the drive shaft of the drive unit is received in the one-way clutch.

A computer-implemented method includes: determining, by a computing device, a location of an individual in a building relative to the location of an exit of the building; determining, by the computing device, the location of obstacles or hazards within the building; determining, by the computing device, a path from the individual to the exit based on determining the location of the individual relative to the exit and the location of the obstacles or hazards; generating, by the computing device, signaling instructions based on the path; and outputting, by the computing device, the signaling instructions to one or more signaling devices, wherein the outputting the signaling instructions control operations of the one or more signaling devices to guide the individual to the exit based on the path.

A training door, door frame, and system are disclosed that allow first responders to train on breaking open locked doors. The door frame provides a channel for a replaceable rod or bar formed of a door material, so that during training, while the rod or bar may be disfigured by repeated training exercises, the remainder of the door and frame remain intact. In this manner, only the rod or bar may need to be replaced after repeated training, rather than the entire door or frame.

A multipurpose vehicular emergency tool has a power source and a plurality of electrical outputs sufficient to act as a jump-starter for a vehicle or to charge mobile electronic devices, in addition to powering a light source to act as a flashlight. A plurality of emergency tools are provided, including a seatbelt cutter and a window breaker, in order to facilitate one's safety and survival in an emergency vehicular situation. Additional features include an emergency flasher light, a plurality of reflective bands, a compass, an emergency alarm, and a thermometer.

A multi-purpose handheld tool including a handle, a hatchet head portion, a saw blade and a saw blade control mechanism. The handle has a first end and a second end. The handle has a slot formed therein. The hatchet head portion is operatively coupled to the first end of the handle. The saw blade is pivotally coupled to the handle. The saw blade control mechanism pivots the saw blade between a storage configuration and a use configuration. The saw blade control mechanism includes a saw control handle and a saw control hub. The saw control handle has a gripping extension extending therefrom. The gripping extension indicates a direction of the saw blade with respect to the handle. The saw control hub engages the saw blade.

A combination seat belt restraint system cutter and glass break tool mounted onto and around the seat belt of an automotive vehicle at a predetermined position for use in cutting the web of the seat belt in the event of a seat belt release latch jam or inoperability resulting in the severing of the seat belt at said position resulting in the tool being freed for use in breaking the glass of a window of the vehicle. The combination tool also being maintained in a fixed position adjacent the safety belt extension/retraction aperture by a strap.

Provided is an assist grip handle storing an escape hammer. The handle is to be attached to an interior space of a vehicle, and includes a bar-shaped grip portion; a curved portion continuous with at least one end of the grip portion; and an attachment portion continuous with the curved portion and attached to an interior member of the vehicle. Since provided inside the grip portion is a storage portion continuous with an opening section formed at the curved portion side, and an escape hammer is stored in the storage portion, the hammer can be stored in the handle in a compact manner. Since there are provided a biasing member biasing the hammer toward the opening section side; a regulation portion for regulating the hammer; and a push button for releasing the restriction by the regulation portion, the hammer can be easily installed in and removed from the handle.

A combination tandem cutting ax head and adz is disclosed that is adapted to firefighting. The ax may include a front end that is divided between a concave portion and a flat section. The concavity creates edges for cutting through surfaces, while the flat section functions to hinder the ax head from becoming wedged in the material. An adz may be provided in which the fulcrum is raised above the head and located between the handle and the adz edge, which increases the lever arm.

The presently disclosed subject matter provides ground-approach forcible entry training trailers that comprise a trailer unit comprising a flatbed and at least two wheels; a frame connected to the trailer unit, wherein said frame is perpendicular to the flatbed and extends along a side edge of the flatbed; and a partial door hingedly connected to the frame, wherein said partial door comprises a locking mechanism at a standard height relative to the bottom of the wheels.
