PURPOSE:To safely and easily scattering a chemical agent dangerous to a human body, by mixing a dilution liquid of the chemical agent and a foaming base agent with compressed air and scattering the resulting liquid mixture while foaming the same in a froth state. CONSTITUTION:Valves 18, 20, 26, 28 are preliminarily regulated at the time of the initial operation so as to obtain a foaming magnification of about 5-100l/kg and a pump 16 and a compressor 24 are energized to start work. The dilution liquid of a chemical agent and a foaming base agent sent through a pipe point is mixed with the air sent through the other pipe joint at the T-shaped pipe part of a foam gum 14 and foamed in a froth state to reach a nozzle 52 from the outlet part of the pipe part through a hose 50 having a length of 5-40m to be emitted as foam. When the state of the scattered foam is set so that the emitted foaming base agent is not formed into mist and the foam is allowed to fly up to about 5m in a lumpy form, the chemical agent can be easily scattered in a state safe to a worker.
