Section 6. Accidental Release Measures
Small SpillUse appropriate tools to put the spilled solid in a convenient waste disposal container. If necessary: Neutralize
the residue with a dilute solution of acetic acid. Finish cleaning by spreading water on the contaminated
surface and dispose of according to local and regional authority requirements.
Large SpillCorrosive solid.
Stop leak if without risk. Do not get water inside container. Do not touch spilled material. Use water spray to
disposal. Neutralize the residue with a dilute solution of acetic acid. Finish cleaning by spreading water on the
contaminated surface and allow to evacuate through the sanitary system.
