Abstract
The machine comprises a first assembly including a vertical post and a carriage track with a movable carriage thereon, the carriage track being pivotally secured to the upper end portion of the post so that the assembly can be collapsed to a size permitting entry into the channel head through a manway, with the assembly being sufficiently light in weight to permit its installation in the channel head by no more than two individuals, the machine further including a separate horizontal support beam and a separate curved track which are independently separably secured to the vertical post and to the outer end of the carriage track so that a generally quadrantally shaped frame is provided, the carriage track carrying an adjustable decontamination blaster means, and means are provided for moving the carriage along the carriage track and for swinging the carriage track both horizontally and vertically in the frame so that the decontamination means has the capability of sweeping past substantially all of the interiorly facing walls in the channel head. The method of carrying out the decontamination of all of the interiorly facing walls in the space in the channel head is accomplished by traversing the areas to be decontaminated by energizing selective drive means for successive sweeps at rates corresponding to the area to be traversed and then stepping the blaster means to different positions and varying the sweep rate in accordance with the different position.
