1. A new and improved hazardous materials training cylinder comprising, in combination:

  • a main housing unit formed in a generally cylindrical configuration with a rounded top, a front region, a rear region including a handle, a flat bottom and an essentially hollow interior, the rear region including wheels rotatably mounted adjacent to the bottom, the top including a plurality of smoke vent holes, a nozzle extending upwardly from the approximate centerpoint of the top, the nozzle including a large water aperture, a small air aperture and a control handle to regulate the flow of air and water therethrough, the nozzle including a lower member with air and water apertures, the lower member extending downwardly into the interior of the main housing unit, the front region including two legs affixed to the bottom, a pinhole leak valve extending through the main housing unit beneath the top, the main housing unit further including upper and lower rectangular recesses positioned within the front region;

    a control panel formed in a generally rectangular configuration and hingedly attached within the upper recess of the front region, the control panel having a plurality of rotatable knobs including a smoke control knob, a supply air knob, a supply water knob, a pinhole air knob and a pinhole water knob, corresponding indicia being located adjacent to each knob;

    an intake panel formed in a generally rectangular configuration and hingedly attached within the lower recess of the front region, the intake panel having a plurality of connection ports formed in a generally circular configuration including an air connection port, a water connection port and a smoke connection port, an air pressure regulator valve and a water pressure regulator valve being releasable couplable within the air and water connection ports respectively, an air hose and a water hose being coupled to the air and water valves respectively, in an operative orientation the air and water hoses being coupled to an air and water source respectively, a smoke reception tube being located within the interior of the main housing unit and formed in a generally cylindrical configuration with a first open end coupled to the smoke connection port, the smoke reception tube including a free second open end, a smoke generator device including a rotatable control knob, the smoke generator device having a large output hose extending therefrom, the output hose having a free end couplable to the smoke connection port;

    an air distribution tube and a water distribution tube, each distribution tube containing a plurality of apertures therethrough and being operatively coupled to the air and water control knobs respectively, a three-way connector being coupled to the water distribution tube and a four-way connector being coupled to the air distribution tube, a smoke control valve being operatively coupled to the smoke control knob;

    a smoke reservoir formed in a generally cylindrical configuration and positioned within the hollow interior of the main housing unit, the reservoir being affixed around the smoke vent holes and lower member of the nozzle, the reservoir having a lower extent including a funnel with a open end, a smoke conduit pipe formed in an elongated cylindrical configuration with a first end coupled to the open end of the funnel and a second end coupled to the smoke reception tube; and

    air and water supply hoses each having a first end coupled to the respective air and water connection ports and a second end coupled to the respective air and water distribution tubes, a water nozzle hose having a first end coupled to the three-way connector and a second end coupled within the water aperture in the lower member of the nozzle, an air nozzle hose having a first end coupled to the four-way connector and a second end coupled within the air aperture in the lower member of the nozzle, a water pinhole hose having a first end coupled to the three-way connector and a second end coupled to the pinhole leak valve, an air pinhole hose having a first end coupled to the four-way connector and a second end coupled to the pinhole leak valve, a short bypass hose having a first end coupled to the four-way connector and a second end coupled within the smoke control valve, an auxiliary air hose having a first end connected to the smoke control valve and a second end connected to the smoke reception tube.
