Lipscomb, J. Provisional Advisory Levels (PALs) for Hazardous Agents . U.S. Environmental Protection Agency, Washington, DC, EPA/600/S-17/044, 2017.

Impact/Purpose:

The unanticipated, emergency release of chemicals can cause harm to emergency responders and bystanders. This product describes advisory exposure levels which help emergency responders decide whether and for how long humans can be temporarily exposed to unanticipated, uncontrolled chemical releases such as accidents, terrorist attacks and natural disasters. The values are derived using peer reviewed risk assessment methods, and they are specifically tailored to the short term human exposures most associated with emergency releases and clean-up operations. Because these exposure values can also inform “what-if…” considerations, they can help emergency planners determine which exposures would result in permanent injury or death; this information can be used to determine how much of a chemical to allow in one place, for instance. These findings will improve our ability and to make more effective decisions regarding the stockpiling of chemicals in quantities less likely to be harmful if released, and to more rapidly decide on courses of action when chemicals are inadvertently released. The results will be useful to emergency planners like Local Emergency Planning Committees, State Emergency Response Commissions, EPA Regional Toxicologists and Risk Assessors, ATSDR Regional Representatives, and emergency responders including those in OLEM/OEM/CAMD and the Emergency Response Team, incident commanders and staff in EPA’s Emergency Operations Center. To address this need, EPA/ORD’s National Homeland Security Research Center (NHSRC) develops health-based Provisional Advisory Levels (PALs) for high priority chemicals including toxic industrial chemicals and chemical warfare agents. This product will be used as a hand-out at professional meetings to promote awareness of NHSRC's Provisional Advisory values. It will be posted on the intra and internet sites describing activities and products of EPA/ORD/NHSRC.
