Emergency Procedures

Prior to responding to any chemical emergency, you must reference the Safety Data Sheet (SDS).

Small Spills (in contained area)

  1. Carefully dilute with water.
  2. Neutralize with weak acetic acid, if necessary.
  3. Vacuum up diluted and neutralized solution for reuse or disposal.

Large Spills (in contained area)

  1. Transfer as much caustic soda solution as possible to secure containers for reuse or disposal.
  2. Carefully dilute remaining caustic soda solutioin with water.
  3. Neutralize with weak acetic acid, if necessary.
  4. Vacuum up diluted and neutralized solution for reuse or disposal.

Spills in Uncontained Areas (e.g., soil, gravel, etc.)

  1. Contain spill and vacuum up as much caustic soda solution as possible for reuse or disposal.
  2. Dig up contaminated soil or gravel for disposal.

It is the responsibility of caustic soda solution users to follow any federal, state, provincial, or local regulations governing disposal. Never discharge caustic soda solution directly into sewers or streams. Releases (spills) of caustic soda solution to the environment may trigger reporting requirements to federal, state, provincial, and local authorities.

In the U.S., it is the responsibility of caustic soda solution users to report spills to the National Response Center (1-800-424-8802) and comply with federal reporting requirements under CERCLA and SARA regulations. The U.S. Coast Guard may also need to be notified under the Clean Water Act.

In Canada, federal and provincial laws require immediate reporting of certain caustic soda solution spills. Users and handlers of caustic soda solution must know and comply with these requirements.
