General spill cleanup guidance:

Small Spills (ex. a "bench top" spill under 1L)

  • Don personal protective equipment (PPE), including eyewear and gloves
  • Pickup any broken glass and place in a puncture resistant container for hazardous waste disposal. Use mechanical means such as forceps to pick up the glass.
  • Using the laboratory spill kit, place absorbent over the spill and give it time to absorb as much of the spill as possible. Place contaminated absorbent in a hazardous waste container.
  • Wash the affected area with a soap solution and place that additional material in the same hazardous waste container as the absorbent and broken glass.
  • Remove gloves and place in the waste container. Seal container, and label as hazardous waste.
  • Remove any additional PPE and wash your hands. NOTE: Any contaminated clothing or PPE may not be taken home nor laundered without additional precautions. Contact AEHS (831)582-4630. for guidance.
