Product Safety Assessment:DO WTM CMIT/MIT--Based Antimicrobial Products Exposure Potential6,7,3 DOWM CMIT/MIT-based antimicrobial products are used in the production of industrial and consumer products. Based on the uses for these products,the public could be exposed through: • Workplace exposure—Exposure can occur in a DOW CMIT/MIT-based antimicrobial products manufacturing facility or in the various industrial or manufacturing facilities that use these products.These materials are produced in closed systems. Personnel working with these products in manufacturing operations could be exposed during maintenance,sampling, testing,or other procedures.Each manufacturing facility should have a thorough training program for employees and appropriate work processes,ventilation,personal protective equipment and safety equipment in place to limit exposure.See Health Information. • Consumer exposure to products containing DOW TM CMIT/MIT-based antimicrobial products—Dow does not sell these products for direct consumer use,but they are used at very low levels in household cleaners,aqueous products like paints,adhesives,and personal-care products.At the dilute use concentrations,no adverse risk is expected. Always read the product information before use and follow the label/use instructions. See Health Information. • Environmental releases—Very small quantities of these materials may be released to the environment if products that contain them are spilled or disposed of down drains. Because the active ingredients in these biocides are highly soluble,once introduced to water,these compounds tend to remain dissolved in water.These compounds are biodegradable and will be removed by wastewater treatment plants. In the event of an industrial spill,the focus is on containing the spill to prevent contamination of soil and surface or ground water. For small spills, DOW CMIT/MIT-based antimicrobial products should be absorbed with inert materials such as sand or clay.The active ingredients in these biocide products are very toxic to aquatic organisms on an acute basis(exposure to a large amount).See Environmental, Health, and Physical Hazard Information. • Large release—Industrial spills or releases are infrequent and generally contained. If a large spill does occur,the material should be captured,collected,and reprocessed or disposed of according to applicable governmental requirements. Keep unprotected personnel from entering the area.An approved respirator is recommended for emergency work.Keep upwind of the spill and ventilate the area.Rinse the spill area with a 5%bleach/5%sodium bicarbonate in water"deactivation solution."Let stand for 30 minutes and then rinse with water. See Environmental, Health, and Physical Hazard Information. • In case of fire—This material will not burn until the water has evaporated.The residue is combustible. Deny unnecessary entry into the area and consider the use of unmanned hose holders. Use water fog,carbon-dioxide or dry-chemical extinguishers,or foam to fight the fire. Firefighters should wear positive-pressure,self-contained breathing apparatus(SCBA)and protective firefighting clothing. Immediately withdraw all personnel from the area in case of rising sounds from venting safety device or discolorations of the container. Contain fire-water run-off if possible to minimize the potential for environmental damage.Follow emergency procedures carefully.See Environmental,Health,and Physical Hazard Information. For more information,see the relevant Safety Data Sheet. Back to top Health Informations Health information for DOW'm CMIT/MIT-based antimicrobial products is summarized on the relevant Safety Data Sheets. Health risks associated with individual products may vary based on their formulation,concentration,or intended use.These materials may contain minor components or additives that have additional health risks.The Safety Data Sheet is the preferred source for specific health information. ®TmTrademark of The Dow Chemical Company("Dow")or an affiliated company of Dow Created:December 17,2010 The Dow Chemical Company Page 4 of 8
