Fire-fighting measuresUse fire-extinguishing media appropriate for surrounding extinguishing mediaNot extinguishingmediaNot a fire hazards arising fromthe chemicalSelection of respiratory protection for firefighting: follow the general fire precautions indicated inthe workplace.

3 Self-contained breathing apparatus and full protective clothing must be worn incase of protective equipmentand precautions for firefightersUse standard firefighting procedures and consider the hazards of other involved fightingequipment/instructionsCool material exposed to heat with water spray and remove it if no risk is methodsNo unusual fire or explosion hazards fire hazards6. Accidental release measuresFor personal protection, see Section 8 of the precautions,protective equipment andemergency proceduresLarge Spills: Scoop spilled materials and recover as much of the product as possible for use. Ifspillage is unrecoverable dispose according to local, state, and federal Spills: Wipe up with absorbent material ( cloth, fleece). Clean surface thoroughly toremove residual and materials forcontainment and cleaning upAvoid discharge to drains, sewers, and other water precautions7. Handling and storageIn case of insufficient ventilation, wear suitable respiratory equipment.

4 Observe good industrialhygiene practices. Use proper lifting for safe handlingStore in a cool, dry, well-ventilated place. Store in a closed container away from incompatiblematerials. Protect from moisture. Keep away from heat. Do not use if material has spoiled, ,there is a moldy appearance or an unpleasant odor. Keep containers closed when not in gallon pails of sealant may be stacked a maximum of 3 layers high on a standard 48 x 48pallet (16 pails per layer, 3 layers high). Pallets may only be stacked a maximum of two for safe storage,including any incompatibilities8. Exposure controls/personal protectionOccupational exposure limitsUS.

For prolonged or repeated skincontact use suitable protective protectionSkin protectionNormal work clothing (long sleeved shirts and long pants) is engineering controls do not maintain airborne concentrations below recommended exposurelimits (where applicable) or to an acceptable level (in countries where exposure limits have notbeen established), an approved respirator must be worn. Use a NIOSH/MSHA approved airpurifying respirator as needed to control exposure.

6 Consult with respirator manufacturer todetermine respirator selection, use, and limitations. Use positive pressure, air-supplied respiratorfor uncontrolled releases or when air purifying respirator limitations may be exceeded. Followrespirator protection program requirements (OSHA and ANSI ) for all hazardsAlways observe good personal hygiene measures, such as washing after handling the materialand before eating, drinking, and/or smoking.
