Ingestion: Rinse mouth, do not induce vomiting unless under direct instruction from a medical expert. Get medical help quickly.
Most Important Symptoms: Burning sensation in eyes, red or dry skin, lightheadedness or dizziness after inhalation.
Advice for Medical Providers: Treat symptomatically, monitor respiratory and cardiovascular function if exposed in high concentrations.
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide. Avoid water jets as product floats on water and may spread fire.
Special Hazards: Vapors can travel; may ignite if they reach a source of ignition. Forms explosive mixtures with air.
Protective Equipment: Wear full protective gear and self-contained breathing apparatus.
Firefighting Procedures: Use water spray to cool containers. Approach fire from upwind, avoid breathing fumes.
Hazardous Combustion Products: Silicon oxides, carbon monoxide, carbon dioxide.
Personal Precautions: Evacuate personnel to safe areas, eliminate all ignition sources, ventilate area
Protective Equipment: Nitrile gloves, chemical splash goggles, chemical-resistant clothing, suitable respiratory protection
Environmental Precautions: Prevent product or contaminated water from entering soil, drains, or waterways
Cleanup Methods: Use inert absorbent (sand, earth), scoop into containers for disposal, flush spill area with water after cleanup
Notification Procedures: Notify local authorities about large spills or if product enters watercourse
Handling: Handle in well-ventilated areas only. Avoid contact with skin and eyes. Keep containers tightly closed. Avoid spraying or atomizing product unless necessary and safe airflow is maintained. No smoking or open flames in the work area. Practice stringent hygiene; wash hands before eating, drinking, or smoking.
Storage: Use only approved containers with secure closures. Store in a cool, dry, and well-ventilated facility away from heat sources and direct sunlight. Separate from oxidizers, strong acids, and reactive chemicals. Maintain temperature between 5°C and 30°C to preserve stability. Store away from direct drain access to prevent accidental discharge. Post clear hazard signage in storage area.
