Sharps contaminated with hazardous materials must be placed in a puncture proof container and sealed with a screw-on cap. The EHS Office provides 1-gallon mayo jars and 20L carboys for this purpose. You can also reuse a rinsed empty chemical bottle for collection of chemically contaminated sharps. The container must be labeled as hazardous waste, with the associated chemicals identified.
After the sharps container is full you can request a pick up and replacement container via the online chemical pick up request form. 1-gallon, 4L and smaller containers should be stored in a secondary containment bin in the labeled SAA. 20L carboys used to collect sharps can be placed on the floor in an area labeled as an SAA without containment bins present.
Examples of a sharp include:
Needle Syringe with material still in it,
Razor blade with chemicals,
Pipettes with visible chemical still inside.
Chemicals of concern include:
Heavy Metals (mercury, lithium, lead, silver, etc)
P-listed (acutely hazardous) materials
Mercaptans / Thiols / Phenols
Peroxide Forming Chemicals
If your sharp is EMPTY, meaning you cannot squeeze a drop out of the syringe or there is NO VISIBLE material inside the pipette, this is considered EMPTY. These sharps can go in your biological sharps bin if you have one in your lab.
If you do not have a bio-sharps bin please collect the sharps in a puncture proof container (4L glass bottle, 1G plastic mayo jar, 20L waste container) and manage as stated above through the hazardous waste collection system.
If your lab simply has clean broken glassware, which cannot be placed in the trash can, please use a rigid puncture proof container, such as a VWR cardboard box marked for glassware.
You may also use a cardboard box but please ensure all sides are taped appropriately prior to requesting the Custodial Services Program to collect for recycling. Check out the Physically Hazardous Broken Glassware tab in the EHS website for more details.
