Clean up spill as soon as possible. For small quantities, wipe off with cloth or paper. For large quantities, recover by using appropriate techniques such as pumping, or absorption with an inert material such as dry sand. Wash contaminated surfaces with water and detergent, and collect waste, washings, and contaminated materials for safe disposal.
SECTION 7: Handling and storage 7.1 Precautions for safe Avoid skin and eye contact with the product, and inhalation of mist, handling using measures as described in Section 8. Use only in a well- ventilated area. Wash hands after use. 7.2 Conditions for safe Store containers in a cool, dry, well ventilated place away from storage, including any direct sunlight. Keep container tightly closed. Exposure to ultraviolet incompatibilities light may cause discoloration.
SECTION 8: Exposure controls/personal protection 8.1 Control parameters Exposure limits Not available.
8.2 Engineering controls Use only in a closed system or provide local exhaust ventilation. 8.3 Individual protection The need for personal protective equipment should be based on a measures workplace risk assessment for the particular use. Avoid skin and eye contact by wearing chemical resistant gloves (recommended: chloroprene rubber, natural rubber, or PVC) and safety goggles. Where more extensive contact may occur, wear suitable protective clothing (e.g. apron, sleeves, boots). Wear respiratory protective equipment (organic vapor mask), if exposure to vapors or mist is foreseen. PPE should be to state or federal standards. Consult manufacturers concerning breakthrough times. We recommend that a safety shower and eye-washing facilities are available in the workplace. SHOWA DENKO CHLOROPRENE 671A_CR-1013US_151009 4/7
