Health hazard evaluation report: HETA-89-342-L2024, Southwestern Indian Polytechnic Institute Clinic, Albuquerque, New Mexico.
In response to a request from the Chief of the Dental Program at the Albuquerque Service Unit of the Indian Health Service, an investigation was undertaken of possible hazardous working conditions at the Southwestern Indian Polytechnic Institute Clinic, Albuquerque, New Mexico. The requestor expressed concern about headaches, mucous membrane irritation and mild nausea experienced by workers at the site. The clinic was a combination teaching and care provider for the Indians of the surrounding area. Three workers had expressed discomfort while working in the dental records section. The building and its heating, ventilation and air conditioning (HVAC) system were examined, representatives from the building management and employees were interviewed, and an environmental survey was conducted. During the study, no environmental agent was identified in the building that would be responsible for the symptoms. Measurements included temperature, relative humidity, carbon-dioxide (124389) levels, all of which were within normal ranges. However, changing environmental factors could alter conditions. The author recommends that the program of maintenance and inspection of the HVAC system be continued. A log should be kept of any employee complaints, with additional information concerning conditions which might affect air quality.
