Health Hazard Evaluation Report: HETA-2005-0076; 2005-0201-3080, Bally's, Paris, and Caesars Palace Casinos, Las Vegas, Nevada, May 2009. Environmental and Biological Assessment of Environmental Tobacco Smoke Exposure Among Casino Dealers

摘要

Between January and April 2005, NIOSH received confidential requests for HHEs from nonpoler (NP) casino dealers at Ballys, Paris, and Caesars Palace casinos in Las Vegas, Nevada. These casino dealers were concerned that exposure to ETS in their workplace was causing a variety of acute and long-term health effects. In response to these requests, NIOSH investigators conducted three onsite evaluations at Ballys, Paris, and Caesars Palace casinos. The first onsite evaluation was conducted July 22-24, 2005, during which we interviewed employees, reviewed OSHA Forms 200 and 300 (Log of Work Related Injuries and Illnesses), and administered a screening questionnaire. The screening questionnaire was used to select potential participants to take a subsequent health symptom questionnaire and undergo environmental and biological monitoring. During the second site visit, from August 21-24, 2005, additional screening questionnaires were distributed to NP casino dealers. A health symptom questionnaire was mailed January 6, 2006, and we conducted biological and environmental monitoring on our final site visit from January 19-22, 2006. During the confidential medical interviews and the open discussions, NP casino dealers reported that they were most concerned about respiratory health effects related to ETS.
