First Aid Measures

Inhalation: Move to fresh air at once, keep airway clear, seek medical attention if breathing difficulty develops, provide rescue breathing if necessary
Skin Contact: Remove contaminated clothing immediately, flush skin with plenty of running water for at least 15 minutes, seek medical advice
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, get immediate medical attention
Ingestion: Do not induce vomiting, rinse mouth with water, never give anything by mouth to an unconscious person, seek medical help
Most Important Symptoms: Burns, redness, severe eye or mucous membrane irritation, difficulty in breathing, coughing, abdominal pain

Fire-Fighting Measures

Suitable Extinguishing Media: Use water fog, foam, dry chemical, or carbon dioxide
Special Hazards: Releases toxic and corrosive gases including hydrogen chloride and sulfur oxides under fire conditions, may react violently with water
Protective Equipment: Firefighters should wear full protective clothing and self-contained breathing apparatus
Advice for Firefighters: Approach from upwind, avoid contact with spilled material, use water spray to cool containers, prevent runoff from entering drains
Explosion Sensitivity: Not expected to be explosive, reacts with water to give heat and corrosive fumes

Accidental Release Measures

Personal Precautions: Evacuate unnecessary personnel, ventilate area, wear chemical resistant gloves, eye protection, and breathing apparatus
Environmental Precautions: Prevent spillage from entering watercourses, drains, or soil
Methods for Clean-Up: Absorb with inert material such as dry sand or commercial absorbent, place in appropriate chemical waste container, ventilate area, wash spill site after material pick-up
Decontamination: Neutralize residues with a solution of sodium bicarbonate or lime
Avoid: Use of water for cleaning, direct skin or eye contact, unprotected exposure to vapors

Handling and Storage

Safe Handling: Use only in well-ventilated areas, avoid inhalation of vapor, prevent contact with skin and eyes, do not breathe dust, vapor, or mist, wash thoroughly after handling
Storage Conditions: Store in cool, dry, well-ventilated place, away from sources of heat and ignition, incompatible with moisture, acids, strong oxidizers, keep container tightly closed and properly labeled
Safe Packaging: Use corrosion-resistant containers, handle and store away from foodstuffs, keep out of reach of children
Precautionary Measures: Training for handlers, proper signage, inspect storage area regularly for leaks or corrosion

Exposure Controls and Personal Protection

Engineering Controls: Use chemical fume hood, ensure eyewash stations and safety showers are nearby, maintain adequate ventilation
Exposure Limits: No established OSHA or ACGIH limits, minimize exposure as a best practice
Personal Protective Equipment (PPE): Use butyl rubber or nitrile gloves, chemical splash goggles, lab coat, full face shield, and appropriate respiratory protection if ventilation is inadequate
Hygiene Measures: Avoid eating, drinking, or smoking during use, wash hands after handling, remove contaminated clothing and wash before reuse
Environmental Controls: Prevent accidental release into drains, ensure exhaust ventilation filters air before release outdoors
