Waste Disposal Changes
Spring 2013
The following changes are being made to our
waste disposal procedures to help reduce
costs and remain in compliance.
It is imperative that students follow these
guidelines as well. Your help and ideas are
welcomed and for all intents and purposes
necessary.
Chemical Waste
The procedures for Chemical Disposal remains
the same.
Animal Tissues
NEW !!
All animal tissues will be
placed in clear plastic
bags. Whenever possible
keep the different
samples separate.
(E.g. cow eyes in one bag, pig
kidneys in another. )
Broken Glass
NEW !!
Lab Glass waste will go into
the blue hard plastic
buckets for recycling. Any
glass that is contaminated
with bacteria must go into
the sharps containers.
Chemical contamination
will be dealt with on a case
by case basis.
(If unsure, bag or box glass separately
to be dealt with later.)
Biohazard Waste
This waste stream is
unchanged except for the
barring of animal tissues.
REMINDER: these red bags
are for non “sharp”
biologically contaminated
wastes: plates, gloves, soft
transfer pipets. Nothing
that would poke through
the red bags.
Biohazard Waste
These hard plastic sealable
buckets are for all the
biological wastes that
would poke through the
plastic bags. Other sharp
objects such as scalpel
blades, needles, broken
glass contaminated with
bacteria, etc.
