  Before using any chemical in the lab, I have to fill in a form that says how the chemical can be dangerous and what I will do to make sure there are no accidents, and if there is an accident, how it needs to be dealt with. Most of the chemicals I use are not very dangerous, but I still have to complete the safety forms.
