ABSTRACT
Results of calculations are shown in Table G-4. The risk of solar space heating appears to be comparable to that of other solar systems.
Some partial estimates of risk are fairly similar to those used here. Ram say (491, 492) assumes 85-95 deaths and 18,000-21,000 injuries for 25 million solar homes annually for finished material acquisition, transpor tation, construction, operation, and maintenance. (A calculational error is corrected in Reference 492.) These references assume, as is done here, amateur as opposed to professional repair, but exclude nonroofing repairs. Risk attributable to storage is not included. These classifications of risk are only part of the total risk of this system. Table G-4 suggests that these components produce about one-half to two-thirds of total risk. Allowing 6000 man-days lost per death and 50 per injury, and 1.27 kW-yr produced per home annually, this is [(85-95) X 6000 + (18,000-21,000) X 50] /1270 X 25 = 44-51 man-days lost/MW-yr.
