Personal Precautions: Evacuate non-essential personnel, ventilate the contaminated area, avoid breathing vapors, prevent contact with skin or eyes
Protective Equipment: Full chemical-resistant suit, gloves, eye and face protection, respirator if ventilation inadequate
Environmental Precautions: Prevent release to waterways, drains, or soil, contain spill using inert absorbent material
Methods for Clean-up: Scoop up with non-sparking tools, place in suitable labeled containers, dispose according to local regulation
Decontamination Procedures: Wash spill area thoroughly with water and detergent after removal of bulk material
Secondary Hazards: Surfaces may remain slick, trace vapors in confined spaces
Precautions for Safe Handling: Avoid skin, eye, and clothing contact, do not inhale mists or vapors, use within a chemical fume hood, keep containers tightly closed
Incompatible Materials: Strong oxidizers, strong acids, moisture, bases that might induce decomposition
Recommended Storage Conditions: Store in a cool, well-ventilated area away from heat sources and sun exposure, keep container sealed, segregate from food and beverages
