Kehoe (2) P.S. -- Dr. Kehoe: Mr. Greenup comments that in certain cases the only way in which a sample could be obtained would be to have our representative enter a barge compartment that had not been freed of gasoline vapor. I am quite sure that you will agree that the urgency of collecting samples does not mean that our men should be unduly exposed to hazardous atmospheres. EKL H 0 0 GS d KJ
