Hydrofluoric Acid Spills

Hydrofluoric acid requires special treatment. Products are commercially available for absorbing hydrofluoric acid. Purchase of hydrofluoric acid spill and personnel exposure material (see first aid kits) is mandatory for laboratories using hydrofluoric acid. Bases can be equally as harmful as acids. Never add a strong acid to a strong base. Use the appropriate neutralizer supplied in the spill kit and follow these steps:

• Apply neutralizer to the perimeter of the spill.

• Mix thoroughly until evolution of gas has stopped.

• Check the pH.

• Transfer the waste to a bag, fill out the appropriate waste label and call the OEHS for a pick-up.

• Clean the spill area with soapy water.
