But my lab manager did walk in at one point and immediately recoiled from the fumes (which we were nose-deaf to at that point).
I don't know whether it's true or not, but I remember a chemistry lecturer telling me that you don't need to worry about terrible smells in the lab, our noses are sensitive to extremely miniscule levels of chemicals. It's when the levels are so high that they have overpowered our senses and knocked out our sense of smell, that's when you need to worry! A wonderfully paradoxical piece of advice...
