Call a physician if symptoms develop or off immediately all contaminated clothing. Rinse skin with water/shower. Call a physician orpoison control center immediately.

4 Chemical burns must be treated by a physician. Washcontaminated clothing before contactImmediately flush eyes with plenty of water for at least 15 minutes. Remove contact lenses, ifpresent and easy to do. Continue rinsing. Call a physician or poison control center contactCall a physician or poison control center immediately. Rinse mouth. Do not induce vomiting. Ifvomiting occurs, keep head low so that stomach content doesn't get into the pain and severe corrosive skin damage. Causes serious eye damage. Symptoms mayinclude stinging, tearing, redness, swelling, and blurred vision. Permanent eye damage includingblindness could importantsymptoms/effects, acute anddelayedProvide general supportive measures and treat symptomatically. Chemical burns: Flush with waterimmediately. While flushing, remove clothes which do not adhere to affected area.

5 Call anambulance. Continue flushing during transport to hospital. In case of shortness of breath, giveoxygen. Keep victim warm. Keep victim under observation. Symptoms may be of immediatemedical attention and specialtreatment neededIF exposed or concerned: Get medical advice/attention. Ensure that medical personnel are awareof the material(s) involved, and take precautions to protect information5. Fire-fighting measuresDry chemical, foam, carbon dioxide, water extinguishing mediaWater. Do not use water jet as an extinguisher, as this will spread the extinguishingmediaDuring fire, gases hazardous to health may be hazards arising fromthe chemicalSelf-contained breathing apparatus and full protective clothing must be worn in case of protective equipmentand precautions for firefightersMove containers from fire area if you can do so without fightingequipment/instructionsUse standard firefighting procedures and consider the hazards of other involved methodsNo unusual fire or explosion hazards fire hazards6.

6 Accidental release measuresKeep unnecessary personnel away. Keep people away from and upwind of spill/leak. Keep out oflow areas. Wear appropriate protective equipment and clothing during clean-up. Do not breathemist or vapor. Do not touch damaged containers or spilled material unless wearing appropriateprotective clothing. Ensure adequate ventilation. Local authorities should be advised if significantspillages cannot be precautions,protective equipment andemergency proceduresShould not be released into the Spills: Stop the flow of material, if this is without risk. Dike the spilled material, where this ispossible. Cover with plastic SHEET to prevent spreading. Absorb in vermiculite, dry sand or earthand place into containers. Prevent entry into waterways, sewer, basements or confined product recovery, flush area with Spills: Wipe up with absorbent material ( cloth, fleece).

9 Ventilation ratesshould be matched to conditions. If applicable, use process enclosures, local exhaust ventilation,or other engineering controls to maintain airborne levels below recommended exposure limits. Ifexposure limits have not been established, maintain airborne levels to an acceptable level. Eyewash facilities and emergency shower must be available when handling this engineeringcontrolsIndividual protection measures, such as personal protective equipmentWear eye/face protection.
