Emergency Procedures: Evacuate area, ensure adequate ventilation, stop leak if without risk
Containment: Prevent further leakage or spillage if safe to do so, avoid runoff into drains, soil, waterways
Cleanup Methods: Absorb spillage with inert non-combustible material (e.g., sand, earth), collect in suitable containers for proper disposal, ventilate area
Disposal: Dispose of collected materials in accordance with local, regional, national regulations
Handling: Avoid direct contact, inhalation of vapor or mist, use only with adequate ventilation, practice good hygiene
Storage: Store locked up, in tightly closed containers, in a cool, dry, well-ventilated place, segregate from acids, oxidizers, and halogens
Specific Requirements: Use corrosion-resistant containers, inspect regularly for leaks or damage, keep away from food and animal feed
Transfer: Use grounded, sealed systems to prevent static, spills, or release
Compatibility: Avoid contact with copper, aluminum, or zinc–corrosive to some metals
Occupational Exposure Limits: OSHA PEL: 1 ppm (4 mg/m³) TWA, ACGIH TLV: 1 ppm (4.2 mg/m³) TWA
Engineering Controls: Local exhaust ventilation, process enclosure, emergency eye wash and shower stations
Personal Protective Equipment: Impervious gloves (nitrile, neoprene), chemical splash goggles, face shield, protective clothing (apron, suit), respiratory protection (approved air-purifying respirator in absence of adequate ventilation)
Monitoring: Regular workplace air monitoring, biological monitoring for exposed workers

Skin Corrosion/Irritation: Causes severe burns, blisters, prolonged contact increases severity
Serious Eye Damage/Irritation: Causes irreversible eye injury, permanent damage possible
Respiratory Sensitization: May cause asthma-like symptoms on inhalation
Skin Sensitization: Prolonged or repeated skin contact may cause allergic reaction
Chronic Effects: Potential for kidney, liver damage from repeated exposure, data from long-term animal studies show organ weight changes
Carcinogenicity: No data supporting carcinogenic effects in humans or laboratory studies
Mutagenicity: Negative in standard genetic toxicity tests
