Agreed.....I had a similar experience during an audit of an Asian Pharma
company. Outside of the US, especially in some of the developing
countries, resources are limited and pipetting by mouth still appears to
be a common technique. A few years back I had a new employee (ex-US) and
we were appalled when he started to pipet by mouth. We quickly acted and
explained to him the right technique and what was the proper equipment to
use to pipet liquids. He was so amazed that with his first paycheck he
ordered a 12 pack of pipet bulbs and sent them back to his ex-US
university so they could start teaching the "new" technique.
From that point forward, the warning of not pipetting by mouth has stayed
in all our procedures associated with the transfer of liquids........
Perhaps an ACS educational initiative for the ex-US, with respect to this
technique, may be something to consider.....

Re: [DCHAS-L] Pipetting rule
Some of the mouth pipette experience may be coming from abroad. During a
routine safety inspection of non-US facilities in both Asia and the
mid-east, mouth pipetting was considered common & a time saving technique.
A mouth siphoning apparatus was also in common use – including for
vehicle/motor bike transfers on company property.

I know of one chemist who thought it would be a good idea to start a
siphon
by mouth to reduce the volume of an over-filled solvent waste drum. I
don't
know if it can be attributed to his being foreign or what. If it isn't
said,
it isn't policy--I had to re-do an SOP to address this.

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?
