As discussed above, the highest excess of risk estimate from the OSHA exposure data was 0 .4 asb esto s-related deaths over a 40-year period. This is almost 300 times less than the chances of being struck by lightning in a sin g le year and approximately 5,000-20,000 times less than the annuaJL risk from such common consumer hazards as food ingestion, poisoning, fire s and f a l l s .
We submit th a t the risk from consumer exposure to asbestos during jo in t taping is not an "unreasonable risk " within the meaning of the s ta tu te . The evidence availabTe to the-Commissi on contradicts rath er than suppors the finding th a t such a risk e x is ts .
Very tru ly yours,
