Impurities: Not expected to pose additional hazards at trace levels; confirmatory analysis recommended if used in food or feed applications.
Inhalation: Move exposed person to fresh air; call medical personnel if symptoms persist or worsen.
Eye Contact: Rinse immediately with plenty of water for several minutes; remove contact lenses; continue rinsing; seek medical attention urgently.
Skin Contact: Remove contaminated clothing; wash affected skin with soap and water; seek medical help if irritation develops.
Ingestion: Rinse mouth; do not induce vomiting unless directed by medical staff; seek immediate medical advice; provide information on the material.
Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide.
Unsuitable Media: Direct water stream may spread spilled material.
Specific Hazards: Product decomposition may release toxic fumes including hydrogen iodide and nitrogen oxides.
Protective Equipment for Firefighters: Self-contained breathing apparatus and full protective gear required.
Fire Fighting Procedures: Move chemicals away from fire area if safe; cool exposed containers with water spray; avoid inhalation of vapors.
Personal Precautions: Prevent contact with skin and eyes; ventilate area; evacuate non-essential personnel.
Environmental Precautions: Stop spill from entering drains, surface water, soil.
Methods for Clean Up: Sweep up and place in suitable, labeled containers for disposal; clean area with water and detergent; avoid generating dust during cleanup; wear appropriate PPE.
Handling: Always wear PPE; use local exhaust or general ventilation; avoid breathing dust and fumes; do not handle near food or feed; avoid contact with eyes, skin, clothing.
Storage: Store in original, tightly closed container; keep in a dry, cool, well-ventilated place; protect from light, moisture, incompatible materials such as strong oxidizers; keep away from foodstuffs, feed, and drinking water.
Exposure Limits: No national exposure limit established; keep dust levels below nuisance standards.
Engineering Controls: Use local exhaust ventilation, process enclosures, or other engineering controls to maintain airborne levels below recommended exposure limits.
Personal Protective Equipment: Chemical splash goggles, gloves resistant to chemical penetration, laboratory coat or coveralls; use a NIOSH-approved particulate respirator if dust is generated.
Hygiene Measures: Wash hands before eating, drinking, smoking, or using the bathroom; remove contaminated clothing.
