Firefighting Procedures: Remove undamaged containers from danger area if safe, cool exposed containers with water spray
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, complex smoke particulates
Personal Precautions: Wear protective gloves, goggles, and suitable footwear, avoid direct contact and inhalation of vapors
Environmental Precautions: Prevent entry into sewers, surface water, or soil, contain using sand, earth, or absorbent materials
Cleanup Methods: Absorb spill with inert materials (e.g., vermiculite), transfer to sealed containers for safe disposal, clean affected area with water and detergent
Additional Instructions: Use local exhaust or ventilation for large-scale incidents, dispose of cleanup materials according to regulations, notify responsible environmental authorities if significant spillage has occurred
Handling Guidelines: Use in well-ventilated workspace, avoid mist or vapor generation, practice good workplace hygiene, keep away from ignition sources
