Good luck! Be carefull about your definition of chemicals though. Think big! Anything is free game such as any type of oil, lubricant, any flammables, cleaning agents, paints, etc. Working at home on my car I can smell fuel and have oil dripping over my hands. In the the environmental field, you would have to wear protective clothing for your arms and a respirator to do the same. Common sense does not apply anymore.
