"Water, water, and nothing but water - only, ever."
Well said.
And while we're on the topic of water, let's mention a laboratory myth we've all had to deal with that's still out there. The one about used safety shower water being a potential Clean Water Act violation; that one's been around for many years. That lasting lab legend is probably why so many laboratory safety showers lack floor drains.
Who ya gonna call? Myth Busters!
40 CFR =A7 268.2 (e) (4) De minimis losses of characteristic wastes to wastewaters are not considered to be prohibited wastes and are defined as losses from normal material handling operations (e.g. - discharges from safety showers and rinsing and cleaning of personal safety equipment - ).

Dear Colleagues -
I am compelled to comment on this, as a former synthesis chemist. please do not perform chemical reactions on human skin or eyes. That is in fact what you are suggesting, however simplistic. No good will come of it.
I must reiterate the wise words below "Water, water water and nothing but water - only, ever". An immediate 15 minute continuous flushing (no less) is considered best practice. Appropriate PPE & administrative controls can help to mitigate your risk of acid exposure, too.
On the floor, benchtop, etc., bicarb is OK for acid spills when used with due caution, but definitely not on your skin or (good grief!) your eyes!

Friends,
What about having some sodium bicarbonate on hand to neutralize spilled/splashed acid? I would have no problem neutralizing a spill of concentrated nitric or sulfuric acid on the floor or benchtop with baking soda, but what about human skin? Eyes? Thanks.
yours,
Mark

Hello,
We mainly use Sulfuric acid and Nitric acid in our lab. Is there a first aid kit designed for acid that you could recommend?
Thanks,
Wayne
