ABSTRACT:
An apparatus including a mixing tank connected to a source of water supply under pressure, by which the tank can be partially filled with water to be mixed with a poison in powder form, which is admitted to the tank through an access opening, normally closed by a transparent cover forming a window through which the mixing operation can be observed. Spray heads connected to the water supply source spray water across the top of the tank to settle dust from the poison powder, and a suction means communicating with the top part of the tank extracts poisonous fumes, caused by the powder, from the tank and discharges such fumes into a purifying unit from which purified air only is discharged. A pump connected to an outlet of the tank discharges the mixture under pressure to spray heads or other discharge means after first recirculating the mixture to complete the mixing operation.
