In the forward (non-washdown) section, all surfaces except the face of the superstructure and the experimental areas reserved for Project 2.8, were deconteminated by the firehosing, handscrubbing, firehosing procedure. The high pressure, hot liquid jet was used on the face of the superstructure and for a final cleanup of the experimental areas. The remainder of the superstructure and the after deck house were decontamineted by means of firehosing and hendserubbing. The hot liquid jet wes used on all other stern section surfaces.
