Hazardous Waste Guides

Hazardous Waste Labels can be obtained through EHS by EHS Office (619) 594-6778 or by emailing [email protected]. Hazardous waste containers must have a completed hazardous waste label attached before hazardous waste is added to the container. The hazardous waste label must be completed with:

  • Contact person: the person EHS can contact with questions about the hazardous waste
  • Phone number: Contact person’s phone number
  • Building and room#: Where the hazardous waste container is used to collect hazardous waste
  • Accumulation Start Date: the date the first drop of liquid or the first article of solid hazardous waste went into the container
  • Chemical Components: The identity or identities of the ingredient(s) of the hazardous waste container
  • Hazard Boxes: check the SDS’s for the hazards of the waste and check the appropriate boxes.
  • Physical State: Solid or Liquid

SAA’s are the laboratories, shops and studios where the hazardous waste first starts being accumulated, also called points of generation. The point of generation needs to be under the control of the person(s) producing the waste which means it can not be moved from one place to another and needs to stay in one room.

Time Limits: Hazardous waste accumulation containers can be used for up to 9 months after the start of the accumulation date written on hazardous waste labels.. Hazardous waste must be sent to or picked up by EHS after no longer than 9 months.

Quantity Limits: SAA’s cannot contain more than 55 gallons of hazardous waste liquids or 500 pounds of hazardous wastes solids.

Storage Requirements: The hazardous waste must be compatible with the container that it is being stored in. Incompatible hazardous waste must be stored separate from each other by a physical barrier or distance so that if broken the contents of the containers cannot commingle. 

Examples of incompatible hazardous wastes:

  • Flammables and Oxidizers
  • Acids and Bases
  • OrganoMetals and Aqueous Wastes

Submit a biohazardous waste removal request by calling 619-594-6778 or by emailing [email protected].  Biohazardous waste typically includes red bags and medical waste sharps containers.

Address Labels: Address labels must be placed on medical waste sharps containers. If you are not using red bags that are prelabeled then they must be labeled with a generator address label prior to use. It is best to apply the generator address label to the middle or bottom of the red bag so that it is still legible after the red bag is tied.  Red bags must be tied as soon as they are full or no more biohazardous waste will be put into the red bags.

Secondary Containers: Red bags must be inside a secondary container while in use, transport, and storage. Secondary containers must be sterilized before being used again.

Submit a universal waste removal or a universal waste label request by calling 619-594-6778 or emailing [email protected]. Common universal wastes include but are not limited to batteries, lamps, aerosol cans (full or empty), mercury containing items like thermometers and thermostats, and electronic waste. Universal waste has low level hazard properties and cannot be put into the municipal trash.

Storage Requirements: While in transport and storage, universal waste must be in containers compatible with the waste; for example, cardboard boxes are sufficient to contain used lamps. The container must be closed when in storage and opened only when materials are being put into them.

Labeling: A universal waste container must be labeled properly with “Universal Waste”, the identity of what is inside the container, and the date the first item of universal waste went into that container.  The label must be attached before the first waste item goes into a container. For a example, a cardboard box that will be used for used lamps on 9-17-20 may be labeled as follows:

Universal Waste

Used Lamps


Accumulation Time: Universal waste needs to be removed by EHS when the container is full or has reached its nine month accumulation time. Accumulation time is based on the date written on the container’s universal waste label.
