ABSTRACT:
Apparatus and method for thrusting a cover onto a target area from a remote location. The target area may be water containing fish or a hazardous condition such as a fire and/or a chemical spill. The apparatus comprises a housing having an open cavity, a cover within the cavity, and a pressurized gas supply for propelling the cover from the cavity and onto the target area. A guide bar positioned in the housing and a support surface attached to the cover cooperate to impart rotation to the cover as the cover is propelled from the housing. The cover may be impregnated with an agent capable of neutralizing the particular hazard, or such an agent may be injected under the cover after the cover is positioned on the affected area. In the case of a chemical spill, the cover is utilized to contain the liquid and then the liquid can be cleaned up by pumping the liquid from underneath the cover.
