At least one situation where water is not good is lithium. Many years ago I
worked at an Oak Ridge installation where large quantities of lithium were
used. There were buckets of graphite dispersed in oil available. I never
wirnessed it, but if one somehow got lithium (whether burning or not) on
their hands, etc., then immersion in the oil dag was the first action
required.

We had an email inquiry in our MSDS Questions mailbox
today that I thought would be worth discussing on the list.
This person was contemplating the instructions for ski
n
exposure on the MSDS's for phenol, cresol and related materials. =A0The
MSDS's generally say to flush immediately with water while removing aff
ected
clothing, but his concern was that rinsing immediately with water would
present more of a health hazard because doing so would further spread pheno
l-laden
water over a larger area of the body, giving a wider/systemic exposure.
=A0 He was suggesting that spilled material should first be wiped off
the skin using a towel/tissue and then use water.
My thoughts on this are
1. His proposal adds an extra step, and with phenols a
ny
delay is dangerous.
2. The person is either going to have to stop and put
on gloves (see item 1) or else risk further skin exposure on the hands.
3. The phenol-laden rinse water is going to be very qu
ickly
flushed away and have little chance to absorb. =A0It does not
=A0 =A0 =A0seem likely that rinsate could pose
a serious systemic threat, and any threat it does pose pales in comparison
to a delay.
Does anyone have any thoughts/comments to add for our
reply to this question?
Thanks,
Rob Toreki
