                                            HYDROCYANIC ACID
                                                    Poison A or B
                                 Spreading of spilled product may be controlled by absorbing liquid with sand, earth,


  t                            UENCE
                        Once used, sorbent materials pQse the same hazards as the spilled product. Their use adds to
                        the overall volume of contaminated material.
                     MITIGA TION
                        Deplete accumulated liquid pools with pumps or vacuum trucks if possible before applying
                        sorbents. Remove contaminated sorbents to safe storage by mechanical means. Where necessary,
                        neutralize sorbents under guidance of qualified expert.
                TECHNIQUE
                NEUTRALIZATION .      Application of an appropriate neutralization agent may modify the spilled
                   product to a less hazardous substance.
                     CONSEQUENCE
                        Application and removal of chemical agents involves additional environmental risks.
                     MITIGA TION
                        Consult qualified experts for safe neutralization techniques.
                TECHNIQUE
                MECHANICAL REMOVAL ... Contaminated soil and any remaining chemical residue may be removed
                   with shovels or motorized graders, scrapers, loaders, bulldozers, or draglines.
                     CONSEQUENCE
                        Removal equipment may become contaminated and present a hazard to later users.
                        lncompatible equipment may be damaged or corroded. Improper storage of removed materials
                        may result in future spread of contamination. Any flammable vapors or gases present in the
                        area may be ignited by motorized removal equipment.
                     MITIGA TION
                        Decontaminate all equipment after use. Use equipment compatible with spilled product. Store
                        contaminated materials in a safe and secure location. Do not operate motorized equipment in
                        potentially flammable atmospheres. Consult qualified experts for advice where necessary.

                WATER SPILL
                TECHNIQ UE
                STOP USE ... Notify downstream industrial, municipal, and public users to stop water intake or to
                   monitor water for contamination.
                     CONSEQ UENCE
                        Alternative water supplies may be needed to accommodate users.
                     MITIGATION
                        Provide alternative water supplies as needed until water supply is declared safe.
                TECHNIQUE
                CONTAINMENT DIKES . .. Water with dissolved chemical may be contained (or diverted to
                   impoundment area) by di king upper and/or lower bounds to limit volume of water affected and spread
                   of contamination.
                     CONSEQUENCE
                        Earthen dikes may become saturated with water and seep through or collapse. Additional water
                        may cause overflow of diked area or water body boundaries.
                     MITIGA TION
                        Reinforce or modify dikes as necessary. Be alert to conditions that may lead to overflow or dike
                        collapse. Remove contaminated water to impoundment or storage area for later treatment or
                        disposal.
