Curiously, the MSDS indicates SilverShield gloves but does not specifically call out latex gloves as permeable and counter-indicated. This seems like a disastrous error of omission.
> Skin: Causes skin irritation. May be fatal if absorbed through the skin.
I’m sure the actual users read these things thoroughly, and the second point is called out above, but that ___really___ buries the lede.
I read somewhere that in professional dealings with toxic and caustic substances no latex glove would ever be considered impermeable but immediately replaced upon contact with a new pair. The trick is to systematically avoid anything splashing by applying best practices.
Karen Wetterhahn did replace her (latex) gloves immediately after spilling a drop of dimethylmercury on them, but it killed her anyway.
