Hazardous Chemical Waste Training: -
All generators of hazardous waste must attend the Hazardous Chemical Waste Training. -
This will teach you proper identification, storage and disposal of hazardous waste. -
This training is offered at least every week. See the training flyer for details Hazardous Chemical Waste Training. Labeling Requirements for Hazardous Waste Containers: -
A UCLA Hazardous Waste Tag must be placed on each hazardous waste container upon start of accumulation. -
The Online Tag Program (OTP) can be used to print hazardous waste tags right from your printer. -
One account on the OTP can be used for the entire lab. See the OTP website more information and to get your lab signed up. Hazardous Waste Storage: -
Hazardous waste must be transferred to Environment, Health & Safety (EH&S) for disposal within 90 days of being generated. -
Waste containers must be in secondary containment at all times to adequately contain the contents of the container/spilled materials. -
Hazardous waste must always be appropriately labeled with a UCLA waste tag at all times. -
Containers must be closed when not in use. -
Storage of hazardous waste in fume hoods or under sinks is not recommended. -
Hazardous waste that meets the quantity threshold of 55 gallons of hazardous waste or one (1) quart of extremely hazardous waste must be transferred to EH&S for disposal within three (3) days of reaching these set volumes. -
Report damaged containers to EH&S. EH&S can provide assistance to transfer the contents to an appropriate container. -
Mark storage areas according to the type of chemicals kept there (e.g. “Corrosive”, “Flammable”, etc.) -
Containers should be inspected weekly for signs of leaks, corrosion or deterioration. Hazardous Waste Disposal: -
Don't dispose of chemicals down the drain. -
Don't dispose of chemicals via trash cans. -
Don't use hoods to intentionally evaporate chemicals. -
Transport the hazardous waste to your designated pick-up location using a sturdy cart and secondary containment. -
Consult the hazardous waste pick-up schedule for the building specific times and locations of disposal. Special Wastes: - If you have special wastes, you should contact EH&S before bringing them to the pick-up.
- Special wastes include waste from lab clean-outs, unknown chemicals and peroxide forming chemicals (PFCs).
Empty Container Management – For Containers That Once Stored Hazardous Materials: -
Only when no material can be poured or scraped from a container can it be considered empty. Empty containers do not have to be managed as hazardous waste. -
At no time should full or partially full containers be placed in the regular trash. Note: -
All containers that once held extremely hazardous wastes are considered hazardous waste and must be disposed of by EH&S. -
If an empty container is greater than five gallons, it must be picked up by EH&S. Hazardous Waste Segregation: -
All hazardous waste must be segregated into categories to prevent incompatible mixtures. For example, do not mix acids with bases, acids with cyanide compounds, or oxidizers with organic materials. See the incompatibility chart for more details -
Segregate all hazardous wastes and materials by hazard class, NOT alphabetically. Waste Minimization: -
Review each experimental protocol to assure that hazardous reagents are used efficiently and that excess purchases are minimized. -
Conduct microscale research when possible in order to minimize amounts of hazardous materials used and generated. -
If possible, use substances that can be neutralized or stabilized either physically or chemically. -
Use less hazardous substitutes when feasible. -
Check our surplus chemical list before ordering your chemicals to see if they are in our inventory. All chemicals in this program are free to UCLA employees
