Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical advice, never give anything by mouth to an unconscious person
Acute Symptoms: Severe burning pain, blistering, shortness of breath, possible delayed pulmonary effects
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam, use water spray only to keep containers cool
Unsuitable Extinguishing Media: Do not use water jet directly on chemical as violent reaction may occur
Special Hazards: Reacts with water to produce toxic and corrosive gases including hydrochloric acid, may emit silicon oxides under fire conditions
Protective Equipment: Self-contained breathing apparatus, protective suit resistant to corrosive chemicals
Specific Methods: Approach from upwind, prevent run-off entering drains, stay clear of vapor clouds
Personal Precautions: Evacuate unprotected personnel, ventilate area, restrict access, wear appropriate personal protective equipment including respirator and chemical-resistant clothing
Environmental Precautions: Prevent entry into waterways, drains, or soil, contain any spillage with inert absorbent material
Methods for Containment and Cleaning Up: Absorb liquid with sand or non-combustible material, collect material in a suitable container for disposal under strict supervision, neutralize residues using dilute sodium bicarbonate solution, ensure proper disposal following local regulations
Decontamination: Wash spill site thoroughly once clean-up is complete
Precautions: Handle only in a chemical fume hood or well-ventilated area, avoid all personal contact, ground all equipment to prevent static discharge, keep away from all sources of moisture
Safe Handling Advice: Use dedicated and compatible transfer equipment, do not mix with acids or bases, ensure emergency eyewash and safety shower are accessible
Storage Conditions: Store in tightly closed containers under dry inert gas, segregate from acids, bases, strong oxidizing agents, moisture, and incompatible chemicals
Storage Environment: Keep in a cool, dry, well-ventilated space, avoid direct sunlight and temperature extremes
Storage Containers: Use materials resistant to corrosion such as glass or lined steel
Occupational Exposure Limits: No specific OSHA/ACGIH exposure limits, keep airborne concentrations below recommended thresholds using engineering controls
Engineering Controls: Local exhaust ventilation, closed handling systems, explosion-proof equipment design preferred
Personal Protective Equipment: Chemical-resistant gloves, full face shield, tightly fitting goggles, long-sleeved lab coat, impervious apron, respiratory protection (NIOSH-approved full-face respirator or supplied-air respirator for high exposures)
