A method to evaluate short term traumatic fatality risks for hazardous waste site remediation workers for a quantitative basis for the assessment of occupational exposures in remediation feasibility studies was presented. Occupational employment data and work related death rates for occupations involved in hazardous waste site remediation were obtained from Bureau of Labor Statistics data for 11 states. Average annual fatality rates were calculated for 17 occupations involved in hazardous waste site remediation tasks associated with three remediation alternatives: excavation and landfill, capping, and capping plus slurry wall. The most hazardous task was that of truck driver, followed by laborer, oiler, and dozer operator. The truck driver and laborer occupations added most to total exposure hours in each remediation alternative. Weighted average death rates were calculated for each alternative and multiplied by the total person years of exposure for the resultant expected number of fatalities. The conversion of the expected number of fatalities to the risk of experiencing at least one fatality yielded the following results: 0.149 for excavation and landfill, 0.012 for capping, and 0.014 for capping plus slurry wall. The risks were described in reference to the need for more reliable and comprehensive data as well as the need for a more science based, quantitative approach to remediation decisions involving worker risks.
