Iodine Monochloride (ICl): 100%
Chemical Formula: ICl
CAS Number: 7790-99-0
Impurities: Typically not present at hazardous concentrations; consult supplier documentation for specifics
Inhalation: Move affected person to fresh air as quickly as possible, keep at rest, allow to breathe warm humidified air if irritation occurs, seek immediate medical attention
Skin Contact: Remove contaminated clothing and rinse skin with copious amounts of water for at least 15 minutes; immediate medical assistance required
Eye Contact: Rinse cautiously with water for several minutes; remove contact lenses if present and easy to do; continue rinsing; get medical attention without delay
Ingestion: Rinse mouth if conscious, do not induce vomiting, seek immediate medical attention
Suitable Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or appropriate foam; avoid using water jet
Hazards from Combustion: May release toxic fumes, including hydrogen chloride and iodine vapors
Special Protective Actions: Firefighters should wear full protective clothing and self-contained breathing apparatus; evacuate area and fight fire from upwind to avoid hazardous vapors
Unusual Hazards: Strong oxidizer, can react vigorously with organic materials and reducing agents
Personal Precautions: Use chemical splash goggles, impervious gloves, and appropriate respirator; ensure adequate ventilation
Environmental Precautions: Prevent entry into water bodies, sewers, basements, or confined areas; avoid release to environment
Cleanup Methods: Neutralize carefully with sodium thiosulfate or other suitable reducing agent, absorb with inert material such as sand or vermiculite; place in a closed, labeled waste container; decontaminate area with copious water
Handling: Only use in a chemical fume hood or well-ventilated area, wear suitable protective equipment at all times, avoid inhalation of vapors or dust, avoid any contact with skin or eyes, keep away from combustible or incompatible materials
Storage Conditions: Store in a cool, dry, well-ventilated area, away from direct sunlight, moisture, and heat sources; keep containers tightly closed and clearly labeled; isolate from bases, reducing agents, and organics
Occupational Exposure Limits: No established OSHA/ACGIH exposure limits at time of writing; minimize exposure as much as possible
Engineering Controls: Use chemical fume hood, local exhaust ventilation, or other engineering controls to maintain airborne concentrations below recommended limits
Personal Protective Equipment (PPE): High-efficiency respirator (NIOSH/MSHA approved), chemical splash goggles or face shield, acid-resistant gloves, long-sleeved lab coat and pants, chemical-resistant apron if necessary
Hygiene Measures: Wash thoroughly after handling, remove contaminated clothing immediately, clean work area regularly

Vapor Density: Not established, vapor is heavier than air
Chemical Stability: Stable under recommended conditions, decomposes in presence of moisture, light, or heat
Reactivity: Highly reactive with water, strong reducing agents, ammonium compounds, finely divided metals, organic materials
Hazardous Decomposition Products: May emit toxic fumes of iodine and hydrogen chloride
Conditions to Avoid: Contact with moisture, elevated temperatures, exposure to light
Acute Toxicity: Highly corrosive and irritating to all tissues; inhalation of vapors can cause severe respiratory irritation, coughing, shortness of breath, pulmonary edema
Skin Corrosion/Irritation: Causes severe burns, blisters, ulceration
Serious Eye Damage/Irritation: Exposure leads to permanent eye injury, blindness
Ingestion Effects: Swallowing leads to severe corrosive injury to mouth, throat, esophagus, stomach
Chronic Effects: Prolonged or repeated exposure may cause damage to respiratory system, possible sensitization
Carcinogenicity: Not classified as carcinogen by OSHA, IARC, NTP, or ACGIH
Aquatic Toxicity: Very toxic to aquatic organisms, causes long-lasting effects in the aquatic environment
Persistence and Degradability: Reacts and breaks down in environment forming iodine and chloride ions, not readily biodegradable
Bioaccumulation Potential: Iodine compounds may bioaccumulate in aquatic species
Mobility in Soil: Highly mobile in water, persistent in soil, can leach into groundwater
Other Adverse Effects: Avoid release into the environment; hazardous to aquatic life due to toxicity and persistence
Disposal Methods: Consult local, regional, or national requirements for hazardous waste disposal; neutralize with reducing agents such as sodium thiosulfate before disposal, keep away from drains
Contaminated Packaging: Empty containers must be handled as hazardous waste; triple rinse before offering for recycling or disposal
Precautions: Wear protective equipment; dispose through licensed hazardous waste contractor
