Accidental Spills and Disposal

Precautions for handling VERSENE*, VERSENEX,* and VERSENOL* chelating agents are given in the "Health and Handling" section. Those precautions relative to eye and skin contact, inhalation, and ingestion must be observed in case of chelating agent spill, both to protect personnel in the immediate area and those engaged in the cleanup.

Environmental and Disposal Information

Action To Take For Spills/Leaks: Sweep up and wash remainder of spill down with water. Avoid wash water entering natural waterways or public water supplies.

Disposal Method. DO NOT DUMP INTO ANY SEWERS, ON THE GROUND, OR INTO ANY BODY OF WATER. For unused or uncontaminated material, the preferred management options are to send it to a licensed recycler or reclaimer. The same management options are recommended for used or contaminated material although additional evaluation is required (see for example, 40CFR Part 261, "Identification and Listing of Hazardous Waste").

Any disposal practice must be in compliance with federal, state, provincial, and local laws and regulations. Check with appropriate agencies for your location.

As a service to its U.S. customers, Dow can provide lists of companies which recycle, reprocess, or manage chemicals and companies that recondition used drums. Telephone Dow’s Customer Information Center at 800-447-4369 for further details. Or Contact Us directly through this web site.

Combustion Characteristics

These chelating agents, like most organic materials, will burn under the right conditions of heat and oxygen supply. Fires can be extinguished by conventional means.

Fire and explosion hazards with chelating agents occur when dusts are permitted to reach critical levels in air. Combustion products of incinerated chelating agents are typical of burning waste. Incineration should be done in conformance with local, state and federal air pollution standards.

General

Contact with aluminum, copper, copper alloys, zinc, and nickel should be avoided. Copper, zinc and nickel are chelated by VERSENE products. Prolonged contact with copper, zinc and nickel can reduce chelant effectiveness. Such contact can also result in chelant attack on these materials of construction, compromising the integrity of storage vessels or other handling system components.

When liquid chelating agents are in contact with aluminum, hydrogen gas (a fire and explosion hazard) is generated. Strong oxidizing agents such as sodium hypochlorite, chromic acid, potassium permanganate, and higher concentrations of hydrogen peroxide will degrade all the chelating agents.

For complete information on the compatibility of VERSENE chelating agents with various materials, see Safety Data Sheets, for the individual products.

In any disposal of wastes, be certain that applicable federal, state, and local regulations are met.

Safety Data Sheets on the chelating agents are available from Dow and should be reviewed before handling these products.
