This page, of course, does not represent my employer's views--just my own! I've been dealing with aspects of chemical response since 1982, when I graduated from Hardin-Simmons University and was commissioned in the U.S. Army's Chemical Corps, where I spent a very enjoyable decade on active duty before volunteering for President Bush's Drawdown bonus. I'm also Certified Environmental Trainer through the National Environmental Training Association and was a professional member of the American Society of Safety Engineers.
