    Abstract: A method and apparatus to simulate a flow of products from a real fire without reproducing a thermal environment associated with the real fire includes the release of a gas or a mixture of gases with an appropriate density less than air to simulate smoke movement from real fire sources. The buoyant inert gas may be helium. In some embodiments, the buoyant gas is combined with artificial smoke, such as a tracer gas or an inert dye (e.g., a particulate) to provide a visual representation of the location and flow characteristics of the surrogate smoke that is released from a release apparatus. In another embodiment, optical techniques that show differences in gas density are used to visualize the movement of the buoyant gas. The release apparatus includes a control system that follows a prescribed time-dependent flow rate to simulate different fire source configurations and growth rates.

    Abstract: An automatic flow restrictor (12, 112) includes a movement sensor (24, 124) that detects undesired movement of a firefighting apparatus (10) relative to a support surface (26) and automatically reduces the flow of fluid through the apparatus (10) to thereby reduce reaction forces acting upon the apparatus. The sensor may be a slidable member (124) or an actuatable lever (24), for example, that detects movement of the apparatus (10) along or away from a support surface (26), and actuates an adjuster (32, 132) to restrict the flow of fluid until the forces are balanced and the apparatus (10) stops moving relative to the support surface (26).

    Abstract: Method for extinguishing a fire in a space, especially in a tunnel or equivalent, in which method an extinguishing medium is sprayed in the space by means of spraying heads. In a first stage of the method, the flow and temperature of the hot gases produced by the fire are influenced by spraying an extinguishing medium into the space, especially by creating in the space at least one curtain (7) of extinguishing medium, and at least some spraying heads (11, 12) in the space are pre-activated into a state of readiness, and in a second stage at least one spraying head is activated to produce a spray of extinguishing medium. The invention also concerns an apparatus.
