SECTION VI. NEUTRALIZATION

TB 43-0199

SECTION VI. NEUTRALIZATION

The installation on-scene coordinator for hazardous materials spills should be informed that DS2 is in a storage facility.

Per AR 200-1, if a DS2 spill occurs, notify the installation spill response team immediately. They can use sodium bisulfate

solution to neutralize DS2 spills. Check the pH with a meter or pH paper. Add more sodium bisulfate solution until the pH

is brought down to 9.5 or less. Spills on porous surfaces (concrete, wood, etc.) should be cleaned and neutralized

immediately Otherwise DS2 will be absorbed and become an indefinite hazard. After neutralizing a spill with sodium

bisulfate, absorb it on vermiculite (NSN 5640-01-324-2664), clay, or diatomaceous earth. Scoop up all material and any

contaminated soil and place in an epoxy coated drum with a fully removable head and label as "corrosive" in accordance

with EPA and DOT requirements. During spills, provide adequate ventilation and remove any ignition source. Equipment,

grounds, and personnel must be cleaned to the point that no DS2 will be discharged into the environment.

SECTION VII. DISPOSITION

7-1. Disposition. All existing stockpiles of DS2 will be inspected to determine the condition of the material. There will

be no disposing of serviceable DS2 containers. All serviceable DS2 will be reported to HQ AMCCOM (B14) using the

Materiel Returns Program (see chapter 7 of AR 725-50). Leaking or badly rusted/dented containers will be segregated

from serviceable/stocks and reclassified as unserviceable. Unserviceable containers of DS2 are a hazardous waste and

will be managed as such by all Department of Defense activities. Disposal methods for waste DS2 and accumulated spill

cleanup residue must comply with the Resource Conservation Recovery Act, and state and local hazardous waste

regulations. The wastes are corrosive, and have the EPA Hazardous Waste Number of D002.This number should be

used to permit the use of off-site hazardous waste disposal facilities. For disposal of unserviceable stocks of DS2,

coordinate with the Defense Reutilization Marketing Office(DRMO). Disposal methods at overseas military installations

must be in accordance with host country laws. Any additional instructions required for proper disposal of DS2 will be

provided by the installation or higher headquarters environmental office. Unserviceable DS2 can be reported to the

servicing DRMO for inclusion in a hazardous waste disposal contract.
