Waste Labeling

For Reagents that are not used or outdated, or you just want to discard it

  1. Label the bottle with the printed words "Hazardous Waste."
  2. A NFPA hazard warning label.
  3. Your name and the date.

For bottles that are used for collecting Waste Solvents

All waste bottles must have the following information:

  1. A label with the printed words "Hazardous Waste."
  2. A NFPA hazard warning label.
  3. For every deposit of chemical wastes into the container:
    1. the date of each waste deposited into the container.
    2. the amount and composition, in either g, ml, % or molarity.
    3. the full chemical name of the waste(s)
  4. Your name and the date.
  5. The first date collecting started with this bottle.
  6. If it is P-listed.

If you are generating chemical wastes with a consistent composition, then the above label will do.

If you are generating smaller quantities of different chemical wastes that are compatible, then you can use the "bottle log sheet" method to replace requirement 3. Pair the bottle and the log sheet with an index, like your room number plus your initials, some alpha-numeric word, or a code word. Secure the log sheet to the bottle so it will not be misplaced. Each time you deposit waste chemicals into this bottle, record the amount and the name of the waste chemicals on the bottle log sheet. And, please remember, you must also have the other five label requirements on your chemical waste bottles.

For bottles that are used for collecting Solid Wastes
