Inhalation: Remove from exposure zone. Provide oxygen or artificial respiration as needed. Seek immediate medical attention.
Skin Contact: Remove contaminated clothing immediately. Rinse skin with plenty of water for at least 15 minutes. Seek medical assistance if irritation develops.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present. Continue rinsing, get medical help right away.
Ingestion: Rinse mouth with water. Do not induce vomiting unless instructed by a health professional. Get medical attention.

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical powder, foam, carbon dioxide, water spray
Unsuitable Media: Direct water jets
Specific Hazards: Vapors may form explosive mixtures with air. Containers may explode when heated. Hazardous combustion products such as hydrogen bromide, carbon oxides may form.
Personal Protective Equipment for Firefighters: Chemical-resistant suit, self-contained breathing apparatus
Special Instructions: Cool containers with water spray. Avoid inhalation of combustion products. Evacuate nonessential personnel from area.

Accidental Release Measures

Personal Precautions: Wear chemical splash goggles, gloves, lab coat or coveralls, use local exhaust or respirator if vapor is present.
Environmental Precautions: Prevent run-off into surface waters, drains, and sewers. Notify authorities if environmental release occurs.
Spill Cleanup Methods: Absorb liquid using sand, earth, or inert material. Transfer solid or absorbed materials to waste container. Ventilate area and wash spill location with water after pickup is complete.

Handling and Storage

Precautions for Safe Handling: Use in a chemical fume hood or well-ventilated space. Avoid inhalation, ingestion, and contact with skin or eyes. Wash hands after use.
Storage Conditions: Store in a tightly closed container, in a cool, dry, well-ventilated area, away from incompatible substances such as strong bases, oxidizers, or acids. Protect from light, heat, and moisture.
Incompatible Materials: Strong oxidizing agents, strong bases or acids

Exposure Controls and Personal Protection

Engineering Controls: Laboratory fume hood or exhaust ventilation, eyewash station and safety shower
