    摘要： This avalanche triggering system includes a portable unit configured to be carried by an operator, the portable unit comprising a gas storage device configured to store an oxidizing gas and a combustible gas; an explosion unit which is configured to be launched by the operator or to be transported by a drone and which includes a flexible envelope configured to be filled with an explosive gas mixture, the flexible envelope being deformable between a rest configuration in which the flexible envelope has a first inner volume and an inflated configuration in which the flexible envelope has a second inner volume which is greater than the first inner volume, the explosion unit further including an ignition device configured to trigger the explosion of the explosive gas mixture contained in the flexible envelope; and a control unit configured to remotely control the ignition device.

    摘要： A device for an avalanche triggering system adapted to cooperate with a blasting chamber and including a support frame adapted to be detachably mounted on the blasting chamber, a diffusion chamber, partially delimiting an inner mixing cavity in which is housed a gas mixer configured to produce a gas mixture, the diffusion chamber further having a diffusion opening configured to allow the passage of the gas mixture to the outside of the diffusion chamber, and an ignition system configured to trigger an explosion of the gas mixture, where the diffusion chamber allows placing the device in an operating position configuration in which the device rests, by gravity, on the blasting chamber.

    摘要： A breaching pole is provided including an elongated handle, an elongated arm joined with the elongated handle and a charge placement arm joined with the elongated arm. The charge placement arm can include a shaft having multiple barbs sized and spaced relative to one another so as to frictionally engage an insert placed over the charge placement arm to secure that insert to the arm. The breaching pole is operable to place the insert adjacent a structure using the charge placement arm and subsequently detonate a breaching device associated with the insert to breach the structure. The insert can define a bore with a sidewall. The charge placement arm registers within the bore. The insert can be constructed from compliant material so the insert deformably engages the barbs as the shaft is inserted into the bore of the insert. A related method of use is provided.
