Dry waste is dry materials that have been contaminated with a hazardous chemical waste. This waste must be handled, stored, and disposed of properly.

Examples of dry waste:

• Contaminated soils
• Dried chemicals that are in scrapable amounts on various surfaces
• Ethidium bromide or acrylamide gels
• Extremely hazardous waste containers
• Debris that is contaminated with extremely hazardous substances.

Contaminated labware includes saturated or scrapable amounts of chemicals on items such as:

• Clean-up debris from a spill
• Containers less than five (5) gallons that are contaminated with chemicals that cannot be easily removed
• Gloves
• Kimwipes
• Pipette tips
• Plastic labware
• Towels.

If labware cannot be cleaned and reused, then:

• Double-bag the contaminated labware in clear plastic bags
• Attach a completed LSCS hazardous waste tag on the bag.
