Appendix 5: Disposal of Chemical Waste

  1. HF must not be poured down drains, except for small quantities involved in washing beakers etc., in which case a large excess of water should be used. For disposal of waste HF, see point 4 below
  2. Other acids may be disposed of via the drains after dilution to <10% concentration, and rinsed away with excess water
  3. Some other chemicals may also be disposed via the drains, for which the permission of the Local Officer for Safety should be sought. If in doubt, consult the University Guidance for Discharges to Drains or the Department Chemistry Officer, Dr Jason Day.
  4. The disposal of hazardous chemicals is arranged by the Department Chemistry Officer. Clearly marked containers must be used for such substances. (See University Guidance for Disposal of Chemical Waste).
