What information does Table 3 provide in the ERG?

Table 3 in the Emergency Response Guidebook (ERG) focuses on the initial isolation and protective action distances for large spills of Toxic Inhalation Hazards (TIH) gases. This table is crucial for emergency responders as it outlines specific distances that should be maintained when dealing with incidents involving TIH, which can pose a significant risk to public health due to their potential for causing harm if inhaled.

The information in Table 3 helps responders make informed decisions about how far people should be evacuated from the hazard zone and where to establish safe perimeters to protect both the public and emergency response personnel. It also includes recommended protective actions that should be taken during an incident, such as sheltering in place or evacuation, depending on the severity and circumstances surrounding the spill. This level of detail is necessary to ensure an effective and swift response to hazardous material incidents involving TIH gases.

Other tables may provide guidance for handling hazardous materials, general distancing for smaller spills, or containment procedures, but Table 3 is specifically designed to address the serious risks associated with large TIH spills, emphasizing the importance of protective action distances to mitigate exposure risks.
