Note: The general Agency guidance for assessing short-term, infrequent events (for most chemicals, an exposure of 

less than 24 hours that occurs no more frequently than monthly) is to treat such events as independent, acute 

exposures rather than as chronic exposure. (Methods for Exposure-Response Analysis for Acute Inhalation 

Exposure to Chemicals (External Review Draft). EPA/600/R-98/051. April 1998)
