The initial protective action distance (IPAD) is based on the estimated distance at which the public could be at risk of harmful exposure to hazardous materials released during an incident, such as a chemical spill or release. It takes into account factors like the type and quantity of the hazardous material, weather conditions, and topography to determine a suitable distance for protective actions to be taken.
