ABSTRACT
Poisons According to Paracelsus (1494-1541), “Too much of anything is toxic. All substances are poisons; there is none which is not a poison. The right dose differentiates a poison from a remedy.” Why are some chemicals more harmful than others? Structure is the most important factor in toxicity. All matter is made up of protons, electrons, and neutrons. It is how they are arranged that determines if they are food, fuel, or a deadly poison. Hazard Class 6 materials are poisons that are solids and liquids. Some liquids are volatile and produce vapors, which are an inhalation hazard. Volatile poisons that are an inhalation hazard require the transport vehicle to be placarded regardless of the quantity.
