Waste Disposal Changes Spring 2013

Waste Disposal ChangesSpring 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.

Animal TissuesYES:- Dissected materials (preserved)

- String used to tie down dissection spec

No:- Dissection tools- Paper towels from clean up,

as these can go in the regular trash.

Broken GlassYES:- Broken glass.- Used Slides (no bacteria).

No:- Glass Tubes with

microbiology media inside.- Glass that is contaminated

with microbes or with hazardous chemicals.

Biohazard WasteYES:- Microbiology plates (plastic)

- Plastic loops, micro centrifuge tubes.

No:- Glass of any kind- Objects that would likely

poke through the bags- Preserved specimens from

dissections.

Biohazard WasteYES:- Metal and glass objects- Pipet tips used with

bacterial culturesNo:- Paper towels, gloves or

other bulky soft items.
