Methods and materials for Eliminate all ignition sources (no smoking, flares, sparks, or flames in immediate area). Keep containment and cleaning up combustibles (wood, paper, oil, etc.) away from spilled material. Ventilate the contaminated area This product is miscible in water. Large Spills: Stop the flow of material, if this is without risk. Dike the spilled material, where this is possible Use a non-combustible material like vermiculite, sand or earth to soak up the product and place into a container for later disposal. Prevent entry into waterways, sewer, basements or confined areas. Following product recovery, flush area with water. Small Spills: Absorb with earth, sand or other non-combustible material and transfer to containers for later disposal. Clean surface thoroughly to remove residual contamination. Never return spills to original containers for re -use. For waste disposal, see section 13 of the SDS. Wear appropriate protective equipment and clothing during clean-up. Environmental precautions Avoid discharge into drains, water courses or onto the ground. 7. Handling and storage Precautions for safe handling Provide adequate ventilation. Keep away from heat. Keep away from clothing and other combustible materials. Take any precaution to avoid mixing with combustibles. Do not get this material in contact with eyes. Do not taste or swallow. When using, do not eat, drink or smoke. Wear appropriate personal protective equipment. Wash hands thoroughly after handling. Observe good industrial hygiene practices. Conditions for safe storage, Keep away from heat. Store in a cool, dry place out of direct sunlight. Store in original tightly including any incompatibilities closed container. Store in a well -ventilated place. Do not store near combustible materials. Store away from incompatible materials (see Section 10 of the SDS). 8. Exposure controls/personal protection Occupational exposure limits No exposure limits noted for ingredient(s). Biological limit values No biological exposure limits noted for the ingredient(s). Appropriate engineering Good general ventilation (typically 10 air changes per hour) should be used. Ventilation rates controls should be matched to conditions. If applicable, use process enclosures, local exhaust ventilation, or other engineering controls to maintain airborne levels below recommended exposure limits. If exposure limits have not been established, maintain airborne levels to an acceptable level. Provide eyewash station. Individual protection measures, such as personal protective equipment Eye/face protection Wear safety glasses with side shields (or goggles) and a face shield. Skin protection Hand protection Wear appropriate chemical resistant gloves. Suitable gloves can be recommended by the glove supplier. Be aware that the liquid may penetrate the gloves. Frequent change is advisable. Other Wear suitable protective clothing. Respiratory protection In case of insufficient ventilation, wear suitable respiratory equipment. Thermal hazards Wear appropriate thermal protective clothing, when necessary. General hygiene Keep from contact with clothing and other combustible materials. Remove and wash contaminated considerations clothing promptly. Keep away from food and drink. Always observe good personal hygiene measures, such as washing after handling the material and before eating, drinking, and/or smoking. Routinely wash work clothing and protective equipment to remove contaminants. 9. Physical and chemical properties Appearance Physical state Liquid. Form Clear liquid. Color Colorless.
