Neutralize acids and bases. Spills of most acids or bases should be neutralized unless toxic vapors are present. One must be careful in neutralizing spills because the neutralization process often is vigorous causing splashes and giving off large amounts of heat. Add the absorbents to the spill, working from the outer edges toward the center. Absorbent material such as Oil-Dri, cat litter, or vermiculite are relatively inexpensive and work well, although they are messy.
Spill pillows are much less messy, though more expensive.
Collect and contain the cleanup residues. Spill residues and cleanup materials should be collected and placed into a plastic container. If the residues are totally dry and small in volume, they may be placed in a plastic bag. Place a descriptive label on each container. Decontaminate the area and affected equipment.
