Predicting and managing the potential health risks of sour-gas wells

The development of sour-gas resources in Canada and the United States has prompted concerns about the potential occupational and public health risks of accidental gas releases from wells and pipelines. In this paper we examine methods to assess and manage the health risks of sour-gas wells. We present data and models that we have used to quantify the risks of sublethal and life-threatening exposures to hydrogen sulfide accidentally released from wells located in western Wyoming. 17 refs., 3 tabs.
