“Generally, scientists doing research that involves hazardous materials do what they can to find out how to mitigate the hazards. They learn appropriate ways of handling the materials, of disposing of them, of protecting themselves and others in case of accidents.
“But, knowing the right ways to deal with hazardous materials is not sufficient to mitigate the risks. Proper procedures need to be implemented. Otherwise, your knowledge about the risks of hazardous materials is mostly useful in explaining bad outcomes after they happen.”
