General Advice: Move affected individual away from source of exposure and into fresh air; Administer artificial respiration only if necessary; Do not give anything by mouth when unconscious; Seek medical attention immediately
Inhalation: Immediately remove to fresh air; Keep at rest in position comfortable for breathing; Get prompt medical assistance
Skin Contact: Immediately take off contaminated clothing; Wash skin thoroughly with soap and lukewarm water for at least 20 minutes; Seek medical attention if irritation persists
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do; Continue rinsing for at least 15 minutes; Seek immediate medical attention
Ingestion: Do not induce vomiting; Rinse mouth with water if conscious; Never give anything by mouth to an unconscious person; Obtain urgent medical care
Extinguishing Media: Use dry chemical, carbon dioxide, alcohol-resistant foam, or water spray; Do not use high-pressure water jets, may spread the fire
Specific Hazards: Vapors can form explosive mixtures with air; Containers can explode under fire conditions; Decomposition releases toxic fumes containing nitrogen oxides, silicon oxides, and hydrocarbons
Protective Equipment: Wear full fire-fighting turn-out clothing, including self-contained breathing apparatus
Special Instructions: Cool containers with flooding amounts of water from a safe distance to avoid risk of explosion; Prevent run-off from fire control or dilution from entering water sources or sewers
Personal Precautions: Evacuate all unnecessary personnel; Remove ignition sources; Ventilate area; Use personal protective equipment including gloves, protective eyewear, and chemical-resistant footwear
Environmental Precautions: Prevent entry into drains, waterways, or soil; Notify relevant authorities if significant release occurs
Methods for Cleanup: Absorb with inert materials such as sand, earth, or vermiculite; Sweep or shovel material into suitable drums for recovery or disposal; Wash spill site with soapy water after removal of bulk material
Handling: Only handle the chemical in well-ventilated areas; Avoid contact with skin, eyes, and mucous membranes; Use with proper grounding and bonding to avoid static discharge; Use explosion-proof electrical systems and non-sparking tools
Storage: Store in tightly sealed containers; Keep away from sources of heat, ignition, and direct sunlight; Store in a cool, well-ventilated area equipped with spill containment; Avoid water or moisture in storage area; Do not store with oxidizers, acids, or moisture-sensitive materials
Specific Storage Requirements: Label containers clearly; Keep drums upright and closed when not in use
Exposure Limits: No OSHA or ACGIH threshold limit value established; Handle substance as potentially hazardous
Engineering Controls: Mechanical ventilation and local exhaust to minimize airborne concentrations; Eye wash stations and emergency showers required
Personal Protective Equipment: Chemical splash goggles, face shield, compatible gloves (nitrile, butyl rubber), flame-resistant lab coats, antistatic footwear, respiratory protection if airborne exposure is possible
Hygiene Measures: Practice personal cleanliness; Wash hands before breaks, meals, and after work
