Additional: Cool containers with water, avoid contamination of watercourses
Personal Precautions: Wear chemical-resistant gloves, eye protection, avoid inhalation of vapors
Environmental Precautions: Prevent product from entering drains or waterways, report spills to authorities as required
Containment: Stop leak if without risk, dike to prevent entry into water or soil
Cleanup Methods: Absorb with sand or inert material, place in suitable chemical waste container, ventilate area, wash spill site after material removal
Safe Handling: Use only in well-ventilated areas, avoid contact with skin and eyes, do not breathe fumes or mist, keep containers tightly closed
Storage Conditions: Store in cool, dry, well-ventilated place away from heat or ignition sources, keep away from food and drink, use appropriate containment to avoid environmental contamination
Incompatible Materials: Strong acids, bases, oxidizing agents, halogens
Additional: Use proper grounding and bonding for bulk transfers to avoid static discharge
Exposure Limits: No established workplace exposure limit; minimize airborne concentrations
Engineering Controls: Local exhaust ventilation, eyewash stations, safety showers
Personal Protective Equipment: Chemical safety goggles, face shield, neoprene or nitrile gloves, chemical-resistant clothing, rubber boots
Respiratory Protection: Use approved respirators if engineering controls are inadequate
Hygiene Measures: Wash hands after handling, remove and wash contaminated clothing, avoid eating or drinking near chemical use
