SDS No. 823ASection 4 - First Aid Measures4.1Description of first aid measuresInhalationRemove source(s) of contamination and move victim to fresh air. If breathing has stopped, giveartificial respiration, then oxygen if needed. Contact physician immediately.Eye ContactFlush eyes with plenty of water. If irritation persists, seek medical attention.Skin ContactIn case of skin contact, wash thoroughly with soap and water.IngestionDo not induce vomiting unless instructed by a physician. Never give anything by mouth to anunconscious person.4.2Most important symptoms and effects, both acute and delayedNone known.4.3After first aid, get appropriate in-plant, paramedic, or community medical support.Section 5 - Fire-Fighting Measures5.1Extinguishing MediaWater Fog, Dry Chemical, and Carbon Dioxide Foam5.2Special hazards arising from the substance or mixtureNone known.5.3Advice for firefightersUse water spray to cool fire-exposed surfaces and to protect personnel. Shut off “fuel” to fire. If aleak or spill has not ignited, use water spray to disperse the vapors. Either allow fire to burn undercontrolled conditions or extinguish with foam or dry chemical. Try to cover liquid spills with foam.Because fire may produce toxic thermal decomposition products, wear a self-contained breathingapparatus (SCBA) with a full-face piece operated in pressure demand or positive-pressure mode.Section 6 - Accidental Release Measures6.1Personal precautions, protective equipment and emergency proceduresOnly properly protected personnel should remain in the spill area; dike and contain spill. Stop orreduce discharge if it can be done safely.6.2Environmental precautionsStop spill/release if it can be done safely. Prevent spilled material from entering sewers, storm drainsor unauthorized drainage systems and natural waterways by using sand, earth, or other appropriatebarriers. No special environmental precautions required.6.3Methods and material for containment and cleaning upPut on appropriate protective gear including NIOSH/MSHA approved self-containedbreathing apparatus, rubber boots and heavy rubber gloves. Dike and contain spill; Absorbor scrape up excess into suitable container for disposal; wash area with dilute ammonia solution.Page 2 of 7

SDS No. 823A6.4Reference to other sectionsSee Section 3 for list of Hazardous Ingredients; Sections 8 for Exposure Controls; and Section 13for Disposal.Section 7 - Handling and Storage7.1Precautions for safe handlingUse good general housekeeping procedures. Wash hands after use. Do not get in eyes, on skin oron clothing. Do not breathe vapors or mists. Use good personal hygiene practices.7.2Conditions for safe storage, including any incompatibilitiesKeep container(s) tightly closed and properly labeled. Store in cool, dry, well ventilated place awayfrom heat, direct sunlight, strong oxidizers and any incompatibles. Store in approved containers andprotect against physical damage. Keep containers securely sealed when not in use. Indoor storageshould meet local standards and appropriate fire codes. Containers that have been opened must becarefully resealed to prevent leakage. Empty containers retain residue and may be dangerous. Avoidwater contamination.7.3Specific end use(s)These precautions are for room temperature handling. Other uses including elevated temperaturesor aerosol/spray applications may require added precautions.Section 8 - Exposure Controls / Personal Protection8.1Control parametersNone defined8.2Exposure controlsRespiratory ProtectionRespiratory protection is not normally required when using this product in open environments withadequate ventilation.Hand ProtectionWear any liquid-tight gloves such as butyl rubber, neoprene or PVC.Eye ProtectionSafety glasses with side shields per OSHA eye- and face-protection regulations 29 CFR 1910.133and European Standard EN166.
