Hi all,
I am just trying to find some information regarding high potent compounds, how they classify, what that mean in term of toxicology, exposure limits, rules to follow when working with this kind of molecules.
Does anyone have a policy for working with high potent chemicals.
Thanks in advance,
Nadia
