Health hazard evaluation report: HETA-93-1110-2575, Martin County Courthouse and Constitutional Office Building, Stuart, Florida.
NIOSH 1996 May; :1-27
In response to a request from the Martin County Board of County Commissioners, an investigation was begun into possible exposure to toxicogenic fungi during the renovation of microbiological contaminated areas of the Martin County Courthouse Complex (SIC- 9211) in Stuart, Florida. Severe contamination was present, consisting predominantly of Aspergillus, Penicillium, and Stachybotrys. Due to occupant health complaints the Courthouse complex was not occupied. Prior to beginning remediation efforts, an initial environmental assessment had been made in September of 1993, by NIOSH investigators. Follow up site visits were conducted in October and November. After completion, a final visit was made in June of 1994. Containment areas with dedicated supply and exhaust ventilation systems were used in the remediation activities. While containment areas reduced the dissemination of spores, potentially toxicogenic fungal spores were identified on 56% of the filter samples collected outside the containment areas. The authors conclude that workers were exposed to a potential health hazard during removal of the microbiologically contaminated building materials. The authors note that workers performing renovations in buildings contaminated with fungi may unknowingly put themselves and other occupants of the buildings at risk for exposure.
