Fire Fighting Instructions: Firefighters should wear self-contained breathing apparatus and full protective clothing. Use water spray to cool containers. Approach from upwind to avoid hazardous vapors.
Personal Precautions: Use personal protective equipment including safety goggles and gloves. Avoid inhalation of vapors.
Environmental Precautions: Prevent further leakage or spillage. Do not let product enter drains, watercourses, or soil.
Containment: Cover spilled liquid with absorbent material such as sand, earth, or vermiculite. Shovel into containers for disposal.
Cleanup: Ventilate area. Wash spill site after material pickup. Use non-sparking tools when working near spill.
Safe Handling: Work in well-ventilated areas. Keep away from heat, sparks, and open flames. Use spark-proof equipment and grounding measures. Do not eat, drink, or smoke while handling.
Storage Conditions: Store in cool, dry, and well-ventilated place away from incompatible substances like strong acids, bases, and oxidizers. Keep tightly closed in original container.
Incompatible Materials: Avoid storage with strong oxidizing agents, alkalis, and acids to prevent hazardous reaction.
Packaging Materials: Use containers made of stainless steel, glass, or approved plastic.
Exposure Limits: No specific occupational exposure limits established. Use recommended guidelines for solvents.
Engineering Controls: Use local exhaust ventilation or general dilution ventilation to control vapor or mist.
Personal Protection: Wear chemical-resistant gloves (nitrile or neoprene). Use safety glasses or goggles with side shields. If ventilation insufficient, use organic vapor respirator. Wear appropriate protective clothing to prevent skin contact. Emergency showers and eye wash stations should be available near work area.
