LLNL-AM-428479 Table C-1. Waste Absorption and Neutralization Procedures* Waste Category Procedure to Absorb and/or Neutralize** Acid • Contain the spill by surrounding it or by diking the perimeter with scoops of loose waste absorbent material compatible with the substance spilled. Begin at the side(s)where release flows toward drains or other conduits to the environment. • Next, cover the spill with loose, compatible absorbent material,working from the perimeter inward toward the center. Use sufficient quantities to completely cover the liquid. An acid neutralizing absorbent may be substituted, if neutralization is desired. Carefully stir the absorbent-covered spill with a shovel. The mixture will change color when the acid is neutralized. Very small spills may be contained and absorbed solely with an absorbent sock. • Use a shovel to scoop up the loose absorbent into an appropriate container. A chemically resistant broom and dustpan may be used to sweep up absorbent residue. • Use wetted absorbent towels or pads to clean surface area until it tests neutral with pH paper. • Manage all absorbent material as hazardous waste. • If HF comes in contact with the skin or eyes, flush with waterfor a minimum of 15 minutes, rub calcium gluconate directly on affected skin areas, and immediately contact Health Services or d ial 911 or use the call sign"MIKE"if using a hand held rad io.
