At a previous place of employment, we took a 55-gallon drum, had it
fitted
with a standard water spigot on the side near the bottom, and built a
cart with
wheels for it. The cart was high enough that a garden-type hose,
attached
to the spigot could be placed in a low sink so that the water could
easily
be drained. The cart was low enough to avoid a high center of
gravity, so
it would not tip over easily. The wheels should be able to be
locked.
It was easy to roll the semi-filled drum to an appropriate
sink, or,
if one was close by, just place the end of the hose into it. We
kept the
hose short (under 10 feet) to keep it from being snaked across a
room.

Subject: Re: [DCHAS-L] Lab
safety
showers
Last May ANSI introduced standards that require an
annual full
15
minute flush and calculation of the flow rate of eye
washes
and
showers. As the person that checks all 64
eyewashes/
showers on
campus let me say that floor drains would've been
a
godsend. My
showers will fill a 30 gallon bucket
anywhere from 30 seconds to 1
minute. I tried
using a
sump pump to direct the water into a sink,
but those drains
are
overwhelmed in 3 minutes. Where I have windows
that will
open, I run the hose out the building. For those that
I
don't have windows I haven't come up with a good solution
yet.
Ideas
anyone? Physical plant has told me just to
run
hose from the lab on
the 3rd floor all the way through the
building
and out the front
door. I understand the
reasoning
behind prohibiting floor drains -
but can't they come up
with drains
that will remain closed until
someone opens
them?
