the ERG is designed to aid first responders in quickly identifying specific or generic hazards of materials involved in an incident and protecting themselves and the general public during the initial response phase of an incident.Have you ever wondered what those four digit numbers on the placards on the side of trucks and rail cars mean? This is an online version of the guidebook produced by the USDOT for first responders during the initial phase of a Dangerous goods/Haz Mat incident. 2, 2011Provides comprehensive data for each element of the periodic table of elements including up to 40 properties, names in 10 languages and common chemical compounds.
Editor's note: Some chemicals in this database contain more information than others due to the original reason this information was collected and how the compilation was accomplished.While working with material safety data sheets (MSDS), I found that manufacturers sometimes used obscure names for constituent chemicals and I didn't always have a good idea of what I was dealing with.To resolve this problem, over the years, I compiled chemical names and identifiers into a personal database, cross referencing regulatory and health safety information when possible.Colleagues and friends eventually started suggesting that I make my data available on this website so that others could benefit from my efforts -- which I finally did in 2004.The more common, regulated and/or hazardous a chemical is, the more information I will have likely collected it.
