3 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 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. Accidental release measuresKeep unnecessary personnel away.

4 Keep people away from and upwind of spill/leak. Wearappropriate protective equipment and clothing during clean-up. Ensure adequate ventilation. Localauthorities should be advised if significant spillages cannot be contained. For personal protection,see section 8 of the precautions,protective equipment andemergency proceduresPrevent product from entering Spills: Stop the flow of material, if this is without risk. Dike the spilled material, where this ispossible. Absorb in vermiculite, dry sand or earth and place into containers. Following productrecovery, flush area with Spills: Wipe up with absorbent material ( cloth, fleece). Clean surface thoroughly toremove residual return spills to original containers for re-use.

5 For waste disposal, see section 13 of the and materials forcontainment and cleaning upAvoid release to the environment. Inform appropriate managerial or supervisory personnel of allenvironmental releases. Prevent further leakage or spillage if safe to do so. Avoid discharge intodrains, water courses or onto the precautions7. Handling and storageProvide adequate ventilation. Wear appropriate personal protective equipment. Avoid release tothe environment. Observe good industrial hygiene for safe handlingStore in tightly closed container. Store away from incompatible materials (see Section 10 of theSDS).Conditions for safe storage,including any incompatibilities8. Exposure controls/personal protectionNo biological exposure limits noted for the ingredient(s).

6 Biological limit valuesGood general ventilation should be used. Ventilation rates should be matched to conditions. Ifapplicable, use process enclosures, local exhaust ventilation, or other engineering controls tomaintain airborne levels below recommended exposure limits. If exposure limits have not beenestablished, maintain airborne levels to an acceptable engineeringcontrolsIndividual protection measures, such as personal protective equipmentWear SAFETY glasses with side shields (or goggles).Eye/face protectionSkin protectionWear appropriate chemical resistant protection2 / 6 Material name: POLYSTEP B-19 Material ID: 649 Product code: 0943 Version #: 06 Revision date: 06-24-2021 Print date: 06-24-2021 SDS USWear suitable protective case of insufficient ventilation, wear suitable respiratory protectionWear appropriate thermal protective clothing, when hazardsAlways observe good personal hygiene measures, such as washing after handling the materialand before eating, drinking, and/or smoking.
