The weight percent of respirable crystalline silica found in this product is < The OSHA PEL for respirable crystalline silica has been lowered to mg/m3, effective June 23, 2016 with compliance dates of June 23, 2017 for construction and June 23, 2018 for general industry. Testing of this product and its constituents suggests that under normal conditions the expected use of this product will not result in exposure to respirable crystalline silica that exceeds the OSHA PEL.

3 However, actual exposures to respirable crystalline silica on a given jobsite must be determined by workplace hygiene First-aid measuresInhalationDust irritates the respiratory system, and may cause coughing and difficulties in breathing. Moveinjured person into fresh air and keep person calm under observation. Get medical attention ifsymptoms contactContact with dust: Rinse area with plenty of water. Get medical attention if irritation develops contactDust in the eyes: Do not rub eyes. Flush thoroughly with water. If irritation occurs, get Brand PLUS 3 Lightweight All Purpose Joint Compound, Ready-MixedSDS US918506 Version #: 03 Revision date: 02-March-2017 Issue date: 22-January-20141 / 6 IngestionRinse mouth.

5 Self-contained breathing apparatus and full protective clothing must be worn incase of standard firefighting procedures and consider the hazards of other involved methodsCool material exposed to heat with water spray and remove it if no risk is Accidental release measuresPersonal precautions,protective equipment andemergency proceduresSee Section 8 of the SDS for Personal Protective and materials forcontainment and cleaning upLarge 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 precautionsAvoid discharge to drains, sewers, and other water Handling and storagePrecautions for safe handlingAvoid inhalation of dust and contact with skin and eyes.

6 Minimize dust generation andaccumulation. In case of insufficient ventilation, wear suitable respiratory equipment. Observegood industrial hygiene practices. Use proper lifting for safe storage,including any incompatibilitiesStore 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 joint compound may be stacked a maximum of 3 layers high on astandard 48 x 48 pallet (16 pails per layer, 3 layers high). Pallets may only be stacked a maximumof two cartons of joint compound may be stacked a maximum of 3 layers high on a standard 42 x42 or 42 x 48 pallet (16 pails per layer, 3 layers high).

8 Observe occupationalexposure limits and minimize the risk of protection measures, such as personal protective equipmentEye/face protectionWear approved SAFETY protectionHand protectionIt is a good industrial hygiene practice to minimize skin contact. For prolonged or repeated skincontact use suitable protective work clothing (long sleeved shirts and long pants) is protectionIf 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. Consult with respirator manufacturer todetermine respirator selection, use, and limitations.

9 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 hygieneconsiderationsAlways observe good personal hygiene measures, such as washing after handling the materialand before eating, drinking, and/or smoking. Routinely wash work clothing and protectiveequipment separately from regular wash.
