Firefighting Instructions: Remove containers from fire area if it can be done without risk, cool with water spray, avoid inhalation of fumes
Explosion Risk: Containers exposed to fire might explode from vapor buildup
Personal Precautions: Isolate leak or spill area, ventilate the area, avoid breathing vapors, wear chemical-resistant gloves, safety goggles, and protective suits
Environmental Precautions: Prevent material from entering sewers, waterways, or soil
Containment and Cleanup: Absorb spills with inert material such as sand or earth, scoop up and transfer to marked waste containers, wash spill area with water after cleanup, ventilate space during activities
Decontamination: Neutralize residues with weak acid like acetic acid for safety before disposal
Safe Handling: Use in well-ventilated areas, minimize inhalation and contact with skin and eyes, avoid eating, drinking, or smoking when handling the chemical, wash hands thoroughly after use
Storage Requirements: Store in tightly closed containers, in a cool, dry, well-ventilated location away from sources of heat, flame, or direct sunlight, keep separate from acids, copper, and strong oxidizing agents
Incompatible Materials: Do not store with acids, halogenated hydrocarbons, nitrites, or strong oxidizers
Special Measures: Use secondary containment to minimize leak or spill risk, with emergency eyewash stations and showers close by
