Abstract
In response to a request from a group of Pathology Lab employees at the Roudebush Veterans Administration Medical Center (SIC-8071), Indianapolis, Indiana an investigation was begun into possible hazardous working conditions. Workers reported symptoms of eye and upper respiratory irritation. The staff in the Pathology Laboratory included medical technologists and technicians working 8 hours a day performing routine tests. Even though the airborne respirable particulate concentrations were low, settled particulates were noted throughout the laboratory which could contribute to worker health complaints of eye and upper respiratory irritation. Carbon-dioxide (124389) concentrations were below the 800 parts per million guideline for indoor air. Temperature and relative humidity levels were not within the comfort guidelines for optical and acceptable ranges for occupants of buildings. Air velocities were nearly five times hood face velocity, which may cause a pressure difference, allowing contaminants to escape. The author concludes that settled particulates could contribute to eye and respiratory irritation, and that ventilation deficiencies caused thermal comfort problems. The author recommends that excess particulates be reduced by improving housekeeping practices, and thermal comfort problems be resolved by modifying supply air diffusers and adjusting the relative humidity.
