Abstract
An investigation was conducted in two hospital buildings that provide tertiary healthcare services for North-central Montana. Although powdered latex glove use was being phased out, there were concerns over potential reservoirs and airborne exposures of latex allergen. We evaluated latex allergen concentrations in air and in settled dusts collected from floors, chairs, and ventilation systems. Air sampling and ventilation dust microvacuum sampling were conducted using 2micrometer pore size, 37-millimeter (mm) polytetrafluoroethylene (PTFE) filters in open faced cassettes. Air sampling time was during the hours of 7 a.m. to 7 p.m. for four days. Floor and chair dusts were collected onto 142rum diameter glass fiber filters with a commercial vacuum. The filters and dusts were analyzed for latex allergen using a competitive inhibition immunoassay. Latex concentrations in air were below the limit of detection for the method (LOD = 0.16 ng latex allergen/m3). Hospital B had significantly higher concentrations of latex allergen in ventilation system dust than Hospital A. Latex concentrations in ventilation system dust ranged from
