The National Institute for Occupational Safety and Health (NIOSH) received a request for a health hazard evaluation from employees at the Spirit Mountain Casino in Grand Ronde, Oregon. In the request, the employees expressed a concern about noise levels generated in the non-smoking casino area and in the children's arcade. To evaluate their exposures, dosimeters were used to collect personal noise exposure data from slot machine attendants, beverage servers, and pit bosses during weekend afternoon and evening hours which were thought to be the busiest periods. Additional dosimeter measurements were made on employees working in the casino's cashier cages, children's daycare and arcade, and on the ground keeping staff. Area noise samples were collected throughout the casino during customer peak and off-peak hours. The results of the noise evaluation found no employees exposed to occupational noise at levels that are above the evaluation criteria used to assess workers' risk of hearing loss from occupational sources. All dosimeter readings were far below the daily allowable dose regulated by the Occupational Safety and Health Administration for noise or for the implementation of hearing conservation programs nor the NIOSH recommended exposure limits by any employee sampled in this investigation. The area noise samples found no noise source that was potentially harmful to the employees' hearing. No occupational exposure to noise that would harm the hearing of employees at Spirit Mountain Casino was discovered during this evaluation. Because of this, no specific recommendations are offered to alter the workplace. However, it is noted in the report that any addition of slot machines or other renovations that increase the perceived noise levels warrant evaluation of the employees' exposures.
