For heaven's sakes. It is a cardinal rule to NEVER pipette ANYTHING under
ANY circumstances by mouth. Anyone who thinks otherwise is just dumb! It is
in the same category as "Didn't your mother teach you not to touch a hot
pan?" By analogy this extends to siphoning gasoline!

We caught a student in a freshman lab doing it a couple of years ago, so
someone out there is still teaching it.

Subject: [DCHAS-L] Pipetting rule

Colleagues, 

During our annual review of safety rules and printed mataerials, one of my
young colleagues asked me if it is still necessary to include the rule
"Never pipet by mouth." She has never seen it done, and couldn't imagine
anyone who would EVER think of doing it. I guess I could ask the same about
the "No eating or drinking" rule.

Any thoughts?
