This report provides the technical documentation for the values in the ERG2012 Table of Initial Isolation and Protective Action Distances and other information appearing in the ERG Green Pages. The goal of choosing the PADs specified in the Guidebook is to balance the need to adequately protect the public from exposure to potentially harmful substances against the need to minimize the risks and expenses that could result from overreacting to a hazardous materials incident. To quantify this balance, a level of protection is defined to represent the probability that the listed PAD would allow sufficient protection of the public. A 90% level of protection has been used in PAD estimation since the 1990s. The transportation of hazardous materials creates numerous opportunities for the release of toxic substances into the environment as a result of traffic accidents, train derailments, equipment failures, and human error. Many of these toxic substances pose acute hazards to the general public and the emergency response personnel who are the first to arrive at the scene of a release. To help first responders determine whether a shipment is potentially hazardous and decide what actions should be taken if a toxic spill does occur, the Emergency Response Guidebook (ERG) is published by the U.S. Department of Transportation (DOT), Transport Canada, and Secretariat of Transport and Communications of Mexico. |
