Personal Precautions: Wear gloves, protective goggles, lab coat; avoid inhalation or contact
Environmental Precautions: Prevent further leakage or spillage. Keep out of drains, surface water, and groundwater.
Containment and Clean-Up: Absorb with inert material (dry sand, earth). Scoop into chemical waste container. Ventilate area well. Wash contaminated surface thoroughly.
Handling: Handle in well-ventilated areas. Avoid contact with eyes, skin, clothing. Do not eat, drink, or smoke during use.
Storage: Keep tightly closed in original, clearly labeled container. Store at room temperature in a dry, well-ventilated place, protected from moisture and incompatible substances such as strong oxidizers.
Specific Use Statement: For industrial and research purposes only, not for food, drug, or household use.
Engineering Controls: Work under chemical fume hood. Use local exhaust ventilation.
Personal Protection: Chemical-resistant gloves (nitrile recommended), splash-proof goggles, lab coat or protective clothing, if splashing possible use face shield.
Respiratory Protection: For low potential exposure, none necessary. For airborne concentrations above recommended levels, use approved respirator.
