First Aid Measures

Inhalation: Move person to fresh air, keep at rest, seek medical attention if symptoms continue such as coughing, dizziness or breathing difficulty
Skin Contact: Wash with lots of soap and water for at least 15 minutes, remove contaminated clothing, inform medical personnel if irritation or redness persists
Eye Contact: Rinse with water for several minutes, hold eyelids apart, consult a doctor if pain, redness, or vision changes occur
Ingestion: Rinse mouth, never give anything by mouth to an unconscious person, call poison center, seek immediate medical attention

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, foam, carbon dioxide, dry chemical powder
Unsuitable Media: Do not use water jet directly. Can spread fire in certain situations
Specific Hazards: Formation of toxic iodine or nitrogen oxides upon combustion, releases hazardous fumes
Protective Equipment: Self-contained breathing apparatus, full protective gear
Advice for Firefighters: Avoid inhaling combustion gases, keep drums cool with water spray, prevent runoff into drains

Accidental Release Measures

Personal Precautions: Use chemical-resistant gloves and goggles, avoid dust formation, ensure adequate ventilation, evacuate area if necessary
Environmental Precautions: Keep out of waterways, prevent product from entering ground or drains
Cleanup Methods: Scoop up spill with non-combustible absorbent (sand, earth), collect in sealed, labeled container, ventilate area, wash spill site with soap and water after cleanup, dispose in accordance with local regulations

Handling and Storage

Handling: Work in fume hood or well-ventilated space, minimize dust and vapor exposure, wash hands and face before eating or drinking, keep container tightly closed when not in use
Storage: Store in original, clearly labeled, tightly sealed container, keep in cool, dry spot away from incompatible substances (oxidizers, strong acids), protect from moisture and light, restrict access to trained personnel

Exposure Controls and Personal Protection

Exposure Limits: No established OSHA/ACGIH limits
Engineering Controls: Use local exhaust ventilation, safety eyewash stations, keep lab air exchange sufficient
Personal Protective Equipment: Chemical splash goggles, resistant gloves (nitrile, neoprene), lab coat, long sleeves, avoid open sandals
Hygiene Measures: Remove contaminated clothing and wash before reuse, avoid ingestion, never pipet by mouth, keep away from food
