Table D-1 Procedures for Absorbing and Neutralizing Releases (Continued) <br /> Waste <br /> Category Steps to Absorb and/or Neutralize Releases <br /> Acid 1. Contain the release by surrounding it with absorbent socks or by diking the <br /> oxidizer perimeter with scoops of loose absorbent material compatible with the substance <br /> released. Begin at the side(s)where flow is most rapid and on side(s) where <br /> release flows toward drains or other conduits to the environment. <br /> 2. Cover the release with loose,compatible absorbent material,working from the <br /> perimeter toward the center.Use sufficient quantities to completely cover the <br /> liquid.If neutralization is desired,substitute an acid neutralizing absorbent. <br /> Carefully stir the absorbent-covered release with a shovel.The mixture changes <br /> color when the acid is neutralized. <br /> 3. Very small releases may be contained and absorbed solely with an absorbent <br /> sock. <br /> 4. When the release is completely soaked up,discard all absorbent material as <br /> hazardous waste.Use a shovel to scoop up the loose absorbent. Use a chemically <br /> resistant broom and dust pan to sweep up absorbent residue. <br /> 5. Use wetted absorbent towels or pads to clean surface area until it tests neutral <br /> with pH paper. <br /> Other I. Contain the release by surrounding it with absorbent socks or by diking the <br /> oxidizer perimeter with scoops of loose absorbent material compatible with the substance <br /> released. Begin at the side(s)where flow is most rapid and on side(s)where <br /> release flows toward drains or other conduits to the environment. <br /> 2. Cover the release with loose compatible absorbent material,working from the <br /> perimeter toward the center.Use sufficient quantities to completely cover the <br /> liquid.Carefully stir the absorbent-covered release with a shovel. <br /> 3. Contain and absorb very small releases solely with an absorbent sock. <br /> 4. When the release is completely soaked up,discard all absorbent material as <br /> hazardous waste.Use a shovel to scoop up the loose absorbent. Use a chemically <br /> resistant broom and dust pan to sweep up absorbent residue. <br /> 5. Use a wetted absorbent pad to clean surface. <br /> LLNL Site 300 Contingency Plan D-4 January 2015 <br /> Appendix D,Absorbing/Neutralizing Guidelines <br />
