Description

Part I proposes a risk analysis method by which worker exposure to hazardous substances used in laboratory fume hoods may be estimated using results from the ASHRAE 110 method and formulae to extrapolate this information into potential exposure scenarios. Contaminated air leaking from hazardous exhaust systems located inside buildings or fan penthouses can pose a health risk to building occupants and maintenance workers. This is why prudent design practices for new buildings recommend that the fans powering these systems be located outside. In existing buildings with fans located inside or where a penthouse is required for weather conditions, however, it may be necessary to estimate potential worker exposure to hazardous agents released by these systems into the worker's environment. Part II proposes a method and formulae by which this risk may be evaluated based on measurement of leakage using a tracer gas release, capture, and detection method.
