During the project there was one fatal accident at the Jobsite and no accidents resulting in permanent total disability or amputation of an entire member. The improved frequency and severity date during the peak construction period, as reflected above speaks well for the safety program at the Jobsite. To properly evaluate the above accident ratios the following table of camparisons is offered: Construction =< Nat'l.

Among unique safety problems confronted on construction jobs was that encountered in connection with the Phase I activities devoted to decontamination of the Sandstone shot islands. Considerable discussion among personnel of the AEC and H & N revolved around ways and means of working the radioactive ground around the old zero points. After determining the degrees of contamination present, it was initially decided that if the grading and filling could be done without raising a dust, men could work in the areas for an unlimited time. 10—4
