All waste must be in a compatible container with a tight fitting lid. The EH&S Office can provide 5 gallon carboys to those that generate at least one gallon per week. Other acceptable containers include empty and cleaned reagent bottles, or plastic containers.

Lids must be tight fitting.

Labels must accurately describe the contents of the container. If multiple chemicals are present they must be listed with their relative percentages (v/v). The most hazardous chemicals should be listed first. If all chemicals are relatively equal in hazard then they should be listed by percentage. The label must be legible and have the EH&S ID #, building and room number, Principle Investigator and telephone number.

The exterior of the containers should be free of contamination.

The waste should be stored in a cabinet that is specifically designated for the class of chemical. If a cabinet is not available, the waste should be placed in a well-ventilated area away from traffic.
