Waste

safety logoNo hazardous materials down sink or in the trash.
Keeping up on waste is easier than dealing with it later.
Fill out the waste label & date on the first drop.

 

   beaker with unknown wasteNo one wants to deal with it.

   Piles accumulate, people leave, and you are stuck with it.

   What is to be done?

   WASTE is easy to deal with IF you do it at the time of generation.
   Nearly ALL of the problems come from WAITING to deal with it.

For Biohazardous waste see BIOHAZARDS, Sharps waste see SHARPS

1) Find a suitable container.

Able to hold the material - large enough, not dissolved by the waste
Tight fitting lid - NOT A BAG! Exception is using a Zip-Lock bag for DRY WASTE ONLY! 
NEVER USE A BIOHAZARD BAG FOR CHEMICAL WASTE! - the waste collectors will not take it if it is in a biohazard bag! This really confuses them.

2) Use a Hopkins Waste Sticker.

Extra ones are outside Room 26 Loeb on the door.
The moment you first add something to the container,  fill in the start date.
FILL OUT COMPLETELY
- incomplete labels mean it WON'T BE ACCEPTED FOR PICK UP!
(EH&S fills in the WAA date)

waste label

Don't know exactly what it is? Main campus can help figure it out. Bottle remains in your lab until they do however. Please do not abuse this service. An unknown is an AUTOMATIC fine from any inspector and that fine does get charged to your lab.

3) FILL IN START DATE. Did you remember to fill this in on the first drop?

Any waste sticker found without a date will set off all kinds of alarms with inspectors!

4) All waste must be in secondary containment.

2nd containment must be able to hold the waste if it leaks. The container cannot be dissolved by the waste and must be large enough to hold the waste. Note: Closed eppendorf tubes in a zip lock back are by definition in 2nd containment.

5) We are not allowed to store waste in fume hoods.

If you are using a proper container, with a tight fitting lid, it should not be a problem to store elsewhere.

6) Only one waste accumulation site per lab.

Amazing how much more careful you can be when the location is small and you have to deal with it more frequently.
You may use a temporary (< 24 hours) tub or bucket, etc. at your bench, but this should be emptied into the larger container at the lab waste location at the end of each day.

7) Wear appropriate personal protective equipment.

Wear safety glasses, lab coat or apron, and the correct gloves. Most waste can go through vinyl and latex gloves. Thicker neoprene gloves are recommended for waste areas.

8) DON'T OVERFILL!

9) EH&S wil come around every 3 months to pick up your waste.

There are limits as to how long we can keep waste.
Even if the container has only a drop in it, turn it in. Use a smaller container NEXT time.

WHAT IS A WASTE?

empty commercial

old chemical

unwanted chemical

NO

NO

It's not a waste until you declare it a waste.

Obvious waste from an experiment or used chemicals will probably be declared a waste immediately. But old or unwanted chemicals you can keep around your lab for years if you want.

AS SOON AS IT IS DECLARED A WASTE you have 6 months to have it removed from your lab by Chris x216.

declared as waste

YES

If you don't want it in YOUR drinking water . . .

DON'T PUT IT DOWN THE DRAIN! OR IN THE TRASH !
(Landfill seeps into water table)

THIS INCLUDES SEAWATER,GEL STAIN, METHANOL, DRY ICE, ACETIC ACID, ETC.
DO NOT PUT ON THE GROUND OR DOWN THE DRAIN

corroded sink trapThis can only happen with a strong acid being left in the sink overnight. If it is less than pH 4 or greater than pH 10 then it MUST be collected as waste and NOT go down the sink!

DO use traps on vacuum lines so hazardous materials does not go down the drain with water aspirators or into the vacuum pump (where it can destroy the oil or diaphram).

Any biphasic material found in a sink trap is a violation. Solvents, oils and water do not mix. Liquid agar/wax become solid in the sink trap, plugging the sink!

 

REMEMBER: All containers containing chemicals must be labeled. (Not just waste)

2nd. CONTAINMENT:

1) must be able to hold the volume of waste in the primary container.
2) must be able to contain the chemical in question. (i.e. no solvents in a plastic that will dissolve)
3) incompatibles can not be in same 2nd containment (i.e. cyanide and acid)(same as storage groups)

waste in 2nd containment
ALL WASTE AND ALL HAZARDOUS MATERIAL MUST BE IN 2nd CONTAINMENT!

no open waste containers!

NO OPEN WASTE CONTAINERS

REMOVE FUNNELS AND CAP BETWEEN FILLINGS

HPLC, use steps to reduce evaporation by parafilming or covering opening

TRASH CANS

  • STAY OUT OF THE DUMPSTERS AND TRASH CANS!

  • Please breakdown boxes and bring them to recycle area

  • "peanuts" can go in the containers next to the main dumpster

  • Discarded equipment and eWaste should go to John Lee
    (decontaminated of course!)

There are reasons to MINIMIZE WASTE

  • Costs High($)

  • Impact on Environment High

  • hassle great

  • hazardous to you

There are ways to MINIMIZE WASTE:

  • use smaller amounts

  • reuse many times

  • recycle or re-purify

  • find less hazardous way of doing

  • treat to make non hazardous (or less) - only with approval

NON-HAZARDOUS WASTE - click NON-HAZ list to see if your waste qualifies.

Not everything is hazardous . . . PLEASE RECYCLE

recycle symbol

IF the bottle did not contain extremely hazardous material AND that material has been drained to the drop stage AND that material can be safely rinsed with water or soap and water, AND the container is less than five gallows, then and only then: Deface the label, rinse out the container and dispose of the empty bottle into the recycle bin. OTHERWISE, give it to EH&S when they come around.
