Ingestion: Rinse mouth with water, do not induce vomiting, seek medical help right away
Most Important Symptoms: Burning, redness, pain, shortness of breath, blistering, delayed pulmonary effects can occur
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, sand; water spray only in large quantities for cooling, not for direct stream
Specific Hazards: Emits toxic gases on combustion including hydrogen chloride, nitrogen oxides, and phosgene-like decomposition
Protective Equipment for Firefighters: Full protective clothing, self-contained breathing apparatus, chemical resistant gloves and boots
Special Precautions: Approach incident from upwind, remove containers from fire area if safe, cool containers with flooding amounts of water
Personal Protection: Use chemical splash goggles, gloves, suitable protective clothing, respirator certified for organic vapors and particulates
Spill Cleanup Methods: Absorb with vermiculite, sand, or inert absorbent, do not allow spillage to enter drains or waterways, collect in closable containers for disposal
Containment: Ventilate area, stop leak only if risk is low, wash spill site after material pickup, isolate area and restrict unnecessary personnel
Environmental Precautions: Prevent run-off into sewers, soil, surface, and ground waters
Handling: Work with under local exhaust, avoid contact with skin, eyes, and clothing, use correct PPE, keep away from incompatible materials like water, bases, and oxidizers, wash thoroughly after use
Storage: Store in tightly closed original container, in a cool, dry, well-ventilated area, away from acids, bases, moisture, and sources of ignition, avoid exposure to sunlight
Incompatible Materials: Strong bases, water, alcohols, amines, oxidizers, compounds with active hydrogen atom
Occupational Exposure Limits: No specific OEL set; minimize exposure
Engineering Controls: Use chemical fume hood, adequate mechanical exhaust ventilation, separate storage from incompatible substances
Personal Protective Equipment: Splash proof goggles or face shield, chemical resistant gloves (nitrile or butyl), acid resistant apron, appropriate respirator when above exposure limits or during spills
Hygiene Measures: Always remove contaminated clothing, wash thoroughly before eating, drinking, or smoking, maintain eyewash and safety shower in work area

Symptoms: Severe irritation and burns to skin, eyes, mucous membranes; corrosive to respiratory tract, cough, shortness of breath, pulmonary edema
Skin Corrosion/Irritation: Causes blistering, ulceration
Eye Damage/Irritation: Leads to permanent damage if not promptly treated
Chronic Effects: Long-term exposure may cause chronic respiratory or skin conditions
Carcinogenicity: Not classified as carcinogenic by ACGIH, IARC, NTP, or OSHA
Sensitization: Not reported; can aggravate individuals with pre-existing skin or respiratory disorders
Ecotoxicity: Toxic to aquatic organisms; may cause long-term adverse effects in aquatic environment
Persistence and Degradability: Hydrolyzes rapidly in water, releases corrosive and toxic products
Bioaccumulation Potential: Low; hydrolysis prevents accumulation in biota
Mobility: Reacts in soil and water, not expected to persist beyond initial hydrolysis products
Environmental Precautions: Prevent chemical or run-off from entering natural water bodies or sewer systems
