- Smaller containers, less than 50ml (vials, conical, series vials, or chemical bottles) can be collected in a 1-gallon 3mil clear plastic sealable bag together.
- Each vial must have have a secured lid to prevent leakage. Bags cannot contain free standing liquids.
- These must be the same physical state (solid or liquid) and hazard class (flammable and/or toxic).
- Only chemicals with flammable or toxic characteristics can be packaged together in the same bag.
- Corrosives, oxidizers, and reactive chemicals must be tagged and packaged individually.
Labeling:
- Tag must be adhered to a clear 1-gallon plastic bag
- Container Size: List the total amount of material in the bag as the container size. Do not list the individual containers or the 1-gallon bag size. (e.g., 10 vials containing 20 ml = 200 ml)
- Physical State: all container must be the same physical state (all solid or all liquid)
- Chemical Constituents: list all chemicals in bag and corresponding percentages as it related to the total amount of bag not individual containers.
- e.g. a bag with a container of 5 ml of Methanol 15 ml Ethanol = Label list 25% Methanol and 75% Ethanol
- We recommend grouping bottles by the same chemical (i.e all 10 vials are Tretinoin, Powder)
