REACTIVITY Stability Stable Incompatibility None known Hazardous decomposition products None known SPILL, LEAK AND DISPOSAL PROCEDURE Important: When responding to spill or leak of this product, follow recommendations contained in the Handling Precautions section (Section 11) of this MSDS. Initially minimize area effective by the spill or leak. Block any potential routes to water systems (e.g., sewers, streams, lakes, etc.). Based on the product’s toxicological and chemical properties and on the size and location of the spill or leak, assess the impact on contaminated environments (e.g., water systems, ground, air equipment, etc.) There are no methods available to completely eliminate any toxicity this product may have on aquatic environments. Minimize adverse effects on these environments. Determine if federal, state and/ or local release notification is required (see Regulatory Classifications section of this MSDS). Recover as much of the pure product as possible into appropriate containers. Later, determine if this recovered product can be used for its intended purpose. Address clean-up of contaminated environments. Spill or leak residuals may have to be collected and disposed of. Clay, soil or commercially available absorbents maybe used to recover any material that cannot readily be recovered as pure product. Flushing residual material to an industrial sewer, if present at the site of a spill or leak incident may be acceptable if authorized approval is obtained. If product and/ or spill/ leak residuals are flushed to an industrial sewer, insure that they do not come into contract with incompatible materials. Contact the person(s) responsible for the operation of your facility’s industrial sewer prior to intentionally flushing or pumping spills or leaks of this product to the industrial sewer. HANDLING AND STORAGE Handling Keep container tightly closed when unused. Storage Store in well-ventilated location.
