Chemical Waste Management
What is chemical waste?
• Any chemical that is “CRIT”:
– Corrosive: 2 ≥ pH or 12.5 ≤ pH
– Reactive: reacts violently or generates
toxic/flammable gases
– Ignitable: flash point of less than 140° F
– Toxic: cause injury or death by inhalation, absorption,
ingestion, or injection
• Listed wastes
• Universal wastes (e.g., batteries, fluorescent
When do chemicals become waste?
• Expired chemicals
• Spent chemicals/waste that has bee used for
intended purpose
• Unstable materials
• Unwanted surplus
Where to store waste?
• Waste can be stored in the lab in a satellite
accumulation area (SAA)
• Everyone should know where the SAA is
How to store waste?
• Segregate waste by chemical characteristics
(i.e.: flammables should not be stored with
– Same storage principles apply for raw materials as
with waste
• In accordance with storage limits
• All containers must be labeled and intact
• Must be inspected weekly
Hazardous waste label
Chemical waste storage limits
• No more than 2 gallons
of flammable liquids
outside of a flammable
• 10 gallons of waste per
• 1 quart of acutely toxic
(P-listed) waste
What should a weekly inspection
• Check that containers are in good condition
with no leaks
• Containers must be closed with a proper lid
(no parafilm!)
• UCD waste label is attached and completed for
each container
• No incompatible wastes are stored together
• Weekly log sheet should be signed
SAA log sheet
Proper disposal for other non-chemical
hazardous wastes
If you have:
Collect it in a:
Waste contaminated with radioactive materials
Radioactive waste container and dispose through EHS’s
radioactive materials program.
Waste contaminated with potentially infectious
materials such as human blood or human serum
Standard red or yellow plastic biomedical waste tub lined
with a red bag. EHS picks up full biomedical waste tubs for
final disposal.
Sharps contaminated with biomedical or
infectious waste
Rigid sharps container. Place closed sharps containers into a
red or yellow biomedical waste tub, depending on the waste
Sharps contaminated with highly toxic or
carcinogenic chemicals
Rigid sharps container. Place closed sharps containers in
sealed chemical waste container and dispose through EHS as
chemical hazardous waste.
Empty gas cylinders
Dispose through EHS as chemical hazardous waste.
Chemical spill debris
Sealed chemical waste container and dispose through EHS.
