ABSTRACT
There is some evidence that risk estimated here is low (see Appendix E, Section vi). Ramsay (491) notes that 1.11 metric tons correspond to 6.4 X 10"3 trucking and warehousing accidents and 3.0 X 10’5 deaths. Using the present weight of finished materials (steel, copper, etc.) yields (53/ 1.11) X 6.4 X 10‘3 = 0.31 accidents and (53/1.11) X 3.0 X 10"5 = 1.4 X 10‘3 deaths. Allowing 6000 man-days lost per death and 50 per injury, this is 6000 X 1.4 X 10‘3 + 50 X 0.31 = 24 man-days lost/MW-yr. Risk due to transportation of raw materials would be extra. Transportation of nonsand and cement raw materials by rail would produce another (129/ 3500) (15-47) = 0.6-1.7 man-days lost, for a total of 25-26.
