ERG (Emergency Response Guidebook)
A guidebook intended for use by first responders during the initial phase of a transportation incident involving dangerous goods/hazardous materials

For entries highlighted in green follow these steps:

IF THERE IS NO FIRE:

Go directly to Table 1 (green-bordered pages)
Look up the ID number and name of material
Identify initial isolation and protective action distances

IF THERE IS A FIRE or A FIRE IS INVOLVED:

Also consult the assigned orange guide
If applicable, apply the evacuation information shown under
PUBLIC SAFETY

Note 1:
If the name in Table 1 is shown with "(when spilled in water)", these materials produce large amounts of Toxic Inhalation Hazard (TIH) (PIH in the US) gases when spilled in water.
Some Water Reactive materials are also TIH materials themselves (e.g., Bromine trifluoride (UN 1746), Thionyl chloride (UN 1836), etc.).
In these instances, two entries are provided in Table 1 for land-based and water-based spills.
If the Water Reactive material is NOT a TIH and this material is NOT spilled in water, Table 1 and Table 2 do NOT apply and safety distances will be found within the appropriate orange guide.

Note 2:
Explosives are not individually listed by their ID number because in an emergency situation, the response will be based only on the division of the explosive, not on the individual explosive.

For divisions 1.1, 1.2, 1.3 and 1.5, refer to GUIDE 112.

For divisions 1.4 and 1.6, refer to GUIDE 114.

Das ERG dient als Grundlage für das "Handbuch für Gefahrgut-Transport-Unfälle" von Dr.-Ing. Hans-Dieter Nüßler"
In IGS werden unter dem Merkmal "ERG Merkblatt Nr." die zu einem Stoff dazugehörigen Merkblätter (die über einen Link im Original angezeigt werden können) angezeigt.
Sollten zu einem Stoff Daten aus den Tabellen 1 - 3 gehören, werden diese direkt unter dem Merkmal "ERG Merkblatt Nr." dargestellt.
