Chemical Spills

Workplaces that use hazardous materials or chemicals must have procedures in place to address dangerous situations, such as spills or chemical exposures. Developing these procedures in advance can significantly reduce the risk of injuries to personnel and ensure maximum safety for all laboratory workers. Laboratory staff should only clean up small, incidental spills that pose a minimal hazard. Large chemical spills or situations where chemicals may be released into the environment must be managed by Environmental Health and Safety (EHS) and the University Police Department (UPD). Detailed procedures for handling chemical spills are provided on this page.

All laboratories that use or store chemicals must maintain spill control materials to address any potential liquid chemical releases. While the specific spill control measures will depend on the types of chemicals present in the lab, the following list provides general guidelines for possible items to include in a spill kit:

  1. Neutralizing Agents: Options include sodium carbonate, sodium bicarbonate, or sodium bisulfate.
  2. Inert Absorbents: Materials such as kitty litter or vermiculite are recommended. Caution is advised when using rags and sponges, as some chemicals may ignite upon contact with these materials.
  3. Mercury Spill Equipment: If mercury is present in the lab, include a vacuum line, flask, needle-nose pipette, and a trap for mercury spills.
  4. Personal Protective Equipment (PPE): Provide gloves, goggles, aprons, and other protective gear for individuals involved in collecting the spilled material.
  5. Waste Disposal Supplies: Include waste disposal forms and labels, bags, a high-density polyethylene bucket, and a small shovel for the collection of spill clean-up materials prior to disposal with Environmental Health and Safety (EHS).
  6. Commercial Spill Kits: These kits, which can be purchased from laboratory supply companies, typically include instructions, absorbents, neutralizers, and protective equipment.

By following these guidelines, laboratories can be better prepared to handle chemical spills safely and effectively.
