5 Fire-fighting measuresWater fog. Foam. Dry chemical powder. Carbon dioxide (CO2).Suitable extinguishing mediaDo not use water jet as an extinguisher, as this will spread the extinguishingmediaVapors may form explosive mixtures with air. Vapors may travel considerable distance to a sourceof ignition and flash back. During fire, gases hazardous to health may be hazards arising fromthe chemicalFirefighters should wear full protective clothing including self contained breathing protective equipmentand precautions for firefightersIn case of fire and/or explosion do not breathe fumes. Move containers from fire area if you can doso without fightingequipment/instructionsUse standard firefighting procedures and consider the hazards of other involved methodsFlammable liquid and fire hazards2 / 9 Material name: BTC 2125M-80%Material ID: 1794 Product code: 3202 Version #: 05 Revision date: 05-08-2020 Print date: 05-08-2020 SDS US6.

6 Accidental release measuresImmediately evacuate personnel to safe areas. Keep unnecessary personnel away. Keep peopleaway from and upwind of spill/leak. Eliminate all ignition sources (no smoking, flares, sparks, orflames in immediate area). Wear appropriate protective equipment and clothing during encapsulating, vapor protective clothing should be worn for spills and leaks with no fire. Donot breathe vapor. Do not touch damaged containers or spilled material unless wearingappropriate protective clothing. Ventilate closed spaces before entering them. Local authoritiesshould be advised if significant spillages cannot be precautions,protective equipment andemergency proceduresEliminate all ignition sources (no smoking, flares, sparks, or flames in immediate area). Takeprecautionary measures against static discharge. Use only non-sparking Spills: Stop the flow of material, if this is without risk. Dike the spilled material, where this ispossible.

7 Cover with plastic SHEET to prevent spreading. Use a non-combustible material likevermiculite, sand or earth to soak up the product and place into a container for later product from entering drains. Following product recovery, flush area with Spills: Wipe up with absorbent material ( cloth, fleece). Clean surface thoroughly toremove residual not discharge effluent containing this product into lakes, streams, ponds, estuaries, oceans orother waters unless in accordance with the requirements of a National Pollutant DischargeElimination System (NPDES) permit and the permitting authority has been notified in writing priorto discharge. Do not discharge effluent containing this product to sewer systems withoutpreviously notifying the local sewage treatment plant authority. For guidance, contact your StateWater Board or Regional Office of the and materials forcontainment and cleaning upAvoid release to the environment. Contact local authorities in case of spillage to drain/aquaticenvironment.

8 Prevent further leakage or spillage if safe to do so. Do not contaminate water. Avoiddischarge into drains, water courses or onto the precautions7. Handling and storageVapors may form explosive mixtures with air. Do not handle, store or open near an open flame,sources of heat or sources of ignition. Protect material from direct sunlight.
