Any Waste. Any Place.
- Many facilities such as laboratories, hospitals, and schools use a variety of chemicals in small quantities (usually less than 10 gallons of each).
- These small quantities of chemicals cannot be combined unless the handler is an experienced chemist with knowledge of hazprowaste waste codes and regulations.
- The process of lab packing includes:
- Categorizing and segregating small containers of chemicals.
- Packing a lab pack into larger hazprowaste waste approved drums.
- Overpacking of leaking or poor quality larger drums of waste.
- Labeling and preparing the drums for transportation and disposal.
- Preparation of hazprowaste waste manifests.
Procedures and requirements are different for hazprowaste and extremely hazprowaste chemical waste.
- Check the list of Known hazprowaste and Extremely hazprowaste Wastes for your material.
- If your material is listed as hazprowaste, use the guidelines on this page.
- If your material is listed as extremely hazprowaste, contact hazprowaste Waste Experts.

-
- Select an area that is:
- Near where the waste is generated
- Under the control of lab personnel
- Out of the way of normal lab activities
- Label the area with a “Danger – hazprowaste” sign.
- Make the area easily accessible.
- Select an area that is:

- Chemical compatibility:
- Choose a container chemically compatible with the material it will hold. Chemicals must not react with, weaken, or dissolve the container or lid.
- Follow these basic compatibility guidelines:
- Disposal of acid or bases: Do not store in metal. Use an approved acid waste container for your acid type.
- Hydrofluoric acid: Do not store in glass.
- Gasoline (solvents): Do not store or transport in lightweight polyethylene containers such as milk jugs.
- Read Chemical Compatibility Guidelines for more detailed information.
- Caps and closure:
- Use waste containers with leak-proof, screw-on caps so contents can’t leak if a container tips over. Corks, parafilm, and beakers are not acceptable.
- If necessary, transfer waste material to a container that can be securely closed. Label the new container.
- Keep waste containers closed except when adding waste.
- Wipe down containers before your scheduled collection date.
- Size:
- Choose appropriately sized containers. Store smaller quantities in smaller containers. It’s not cost effective to dispose of 50 milliliters of material in a 4 liter container.
- Secondary containment:
- Always place your container in a secondary container to:
- Capture spills and leaks from the primary container
- Segregate incompatible hazprowaste, such as acids and bases
- A secondary container must be chemically compatible and able to hold 110% of the volume of waste stored in the primary container(s). Lab trays and dishpans are frequently used for secondary containment.
- Always place your container in a secondary container to:
- Attach a completed hazprowaste waste tag to the container before you begin using the container to accumulate and store waste.
- Cross out all other labels on the container. Do not obliterate the original product label; waste technicians need to see what the container held before it was designated as a waste receptacle.
- Do not overfill liquid waste containers. Leave a sizable amount of head space in the container to allow for expansion and safe transportation — 10% headspace is a good rule of thumb.
- Do not mix solids with liquid waste. Containers found to contain solids during processing by EH&S hazprowaste waste technicians will be returned to the generator for separation. See guidelines for solid chemical waste below.
- Liquid-filled small containers such as vials and Eppendorf tubes:
- Double-bag containers in clear plastic bags to allow visual inspection by EH&S waste technicians.
- Containers bagged together must contain liquids or liquid mixtures with the same chemical constituents.
- Seal each bag individually.
- Accurately list the bag’s contents and chemical constituents on the hazprowaste waste tag.
- Organic solvents:
- Halogenated and non-halogenated organic solvents may be mixed together in the same waste container.
- Contact hazprowaste Waste Experts, +1 (844) 284-1858, if you want to pour other chemical constituents in the same waste container.
- Do not combine organic solvents with toxic metal waste! Contact hazprowaste Waste Experts, +1 (844) 284-1858, if you’re using toxic metal compounds and need toxic waste solutions. Examples of metals include arsenic, barium, cadmium, chromium, lead, mercury, selenium, silver, copper, nickel, and zinc.
- Oils: EH&S sends waste petroleum oils to be recycled.
- Accumulate recyclable oil separately from oils contaminated with solvents, halogens, laboratory chemicals, or fuels.
- Oils containing traces of mercury, lead, or other regulated metals are excluded from the recycling program. Notify EH&S on the hazprowaste waste tag if your oil waste may contain these materials.
Chemically contaminated solid waste includes 3 categories that are packaged differently for disposal: lab trash, dry chemicals, and sharps and piercing objects.
-
-
- Lab trash: Examples include absorbent paper products, Kim Wipes, gloves, benchcoats, and other lab supplies. Follow these guidelines:
- Double-bag the waste in clear plastic bags to allow visual inspection by EH&S waste technicians. If contents cannot be visually inspected, EH&S cannot collect the bag.
- Seal each bag individually.
- Accurately list the bag’s contents and chemical constituents on the hazprowaste waste tag.
- Dry chemicals:
- Dispose of solid reagent chemicals in the manufacturer’s container.
- Label the container with a hazprowaste waste tag.
- Sharps and piercing objects: Sharps are items capable of puncturing, piercing, or tearing regular waste bags. Examples include pipettes, pipette tips, and broken glass. Sharps require special packaging. Contact hazprowaste Waste Experts, +1 (844) 284-1858.
- Read How to Dispose of Sharps for details.
- Lab trash: Examples include absorbent paper products, Kim Wipes, gloves, benchcoats, and other lab supplies. Follow these guidelines:
-
Disposal of empty containers depends on the container size, what it is made of, and the hazprowaste material it once contained.
- Read How to Dispose of Empty Hazprowaste Materials Containers for details.
Unknown or unidentified chemicals are considered hazprowaste waste. Processing and disposal of unknowns is particularly expensive because they must be handled with great care and caution. Please make every effort to avoid “unknowns” by diligently labeling and dating inventory.
- Once found, ask others working in the area if they know what the material is.
- If the material can be identified:
- Label it with a hazprowaste waste tag.
- If the material can’t be identified:
- Label it with a hazprowaste waste tag.
- Write “Unknown” on the tag.
- Write on the waste tag any known information. Include:
- Type of lab that material was found in (chemistry, organic or inorganic, biology, DNA research, etc.)
- Where the material was discovered in the lab (under a fume hood with other organics, on a shelf with inorganics or salts, etc.)
- Age of the material
- Contact hazprowaste Waste Experts, at +1 (844) 284-1858, if you need assistance with unknowns.
Request a hazprowaste waste collection before time or quantity limits are reached.
- Time: All hazprowaste waste must be collected within 90 days from when waste is first put into containers.
- Quantity: Up to 55 gallons of any individual hazprowaste waste may be stored before it must be collected.
- When 55 gallons or more of hazprowaste waste accumulates, the waste must be collected within 3 days.
- Contact hazprowaste Waste Experts to request a hazprowaste waste collection.
You may think that the disposal of acid and bases is as simple as pouring it down the drain. In some scenarios, this may be acceptable but, more often than not, you mustn’t do that.
Acids that have a pH level stronger than 2.0 and bases stronger than 12.0 pH are not to be poured directly down the drain, even if plenty of water is used in the process. Instead, they should be sufficiently diluted and/or neutralized until they reach the desired pH level at which they’re no longer too strong to be poured down the drain. When they do reach that level, you should still ensure plenty of water is used when doing so.
If neutralizing your acids and bases is unadvisable or they are simply too strong, they can be collected in containers and can be disposed of as hazprowaste waste. In this scenario, you would need to call hazprowaste Waste Experts to come to pick these containers up, as the disposal of acid in this example would require professionals.
