ERG Guide 152 Datasheet (for unassigned UN/NA numbers)
- CAMEO Chemicals has 2 chemical datasheets with response recommendations for the material names listed on this ERG Guide datasheet (for unassigned UN/NA numbers).
The Emergency Response Guidebook (ERG) provides general response recommendations for first responders.
UN/NA datasheets display several items from the ERG: material names, response guide PDFs, initial isolation and protective action distances, warnings about toxic-by-inhalation gases that may be produced if the material spills in water, and polymerization hazards.
The ERG recommendations are developed for use during the initial phase of transportation incidents; they are not intended for spills at facilities.

MD (when used as a weapon) | 1000 ft | 1.0 mi | 2.7 mi | 3000 ft | 7.0+ mi | 7.0+ mi |
PD (when used as a weapon) | 200 ft | 0.3 mi | 0.3 mi | 1000 ft | 1.0 mi | 1.0 mi |
The ERG doesn't predict that large amounts of toxic-by-inhalation gases will be produced if this material is spilled in water.
Map the ERG's Initial Isolation and Protective Action Distances
Use this tool to see the ERG green table values (above) on a map, and you can also export the map objects as a KML file. See the ERG Distances (PDF) for information on using these values and how they were created.
Click on the map (or type in the coordinates) to set the spill location. Then use the choices in the panel to provide additional details about the release.
- DAY is between sunrise and sunset.
- SMALL spills are 55 US gallons (208 liters) or less.
- Enter the direction FROM which the WIND is blowing.
- LOW wind is less than 6 miles per hour (less than 10 kilometers/hour), MODERATE wind is 6-12 mph (10-20 km/h), and HIGH wind is greater than 12 mph (greater than 20 km/h).
Note: These distances are for spills where there is no fire involved.
