Recommended Use: Industrial gas, chemical synthesis, laboratory reagent
Supplier Contact: Refer to packaging or purchasing information for manufacturer details
Emergency Phone Number: Local emergency services or poison control center
GHS Classification: Acute Toxicity (Inhalation) - Category 2; Skin Corrosion/Irritation - Category 1; Serious Eye Damage/Irritation - Category 1; Specific Target Organ Toxicity (Single Exposure) - Category 3
Pictogram: Skull and crossbones, corrosion
Signal Word: Danger
Hazard Statements: Fatal if inhaled. Causes severe skin burns and eye damage. May cause respiratory irritation.
Precautionary Statements: Do not breathe gas. Wear protective gloves, clothing, and eye protection. Wash hands thoroughly after handling. Use only outdoors or in well-ventilated areas. In case of inadequate ventilation, wear respiratory protection.
Chemical Name: Carbonyl Fluoride
CAS Number: 353-50-4
Concentration: 99.5% or higher
Impurities: Trace amounts of other fluorine-containing compounds may be present depending on source; always confirm with supplier
Inhalation: Move person to fresh air immediately. Remove contaminated clothing. If breathing stops, start artificial respiration and seek immediate medical attention. Keep affected individual warm and at rest.
Skin Contact: Flush exposed skin with copious amounts of water for at least 15 minutes. Remove contaminated clothing and shoes. Seek medical help for burns or persistent irritation.
Eye Contact: Rinse eyes immediately with water for a minimum of 15 minutes, holding eyelids open. Seek urgent medical evaluation.
Ingestion: Not a typical route of exposure due to gaseous state; seek immediate medical assistance if accidental ingestion is suspected. Do not induce vomiting.
Suitable Extinguishing Media: Use water spray, dry chemical, or carbon dioxide. Avoid direct contact with gas during fire suppression.
Hazards from Combustion: May release toxic and corrosive gases including hydrogen fluoride, carbon monoxide, and carbon dioxide when decomposed in fire.
Protective Equipment: Use full-face positive-pressure self-contained breathing apparatus (SCBA) and full protective gear.
Special Procedures: Evacuate area. Cool containers with water spray to prevent pressure buildup and potential explosion.
Personal Precautions: Evacuate unauthorized personnel. Ventilate area and avoid inhaling vapors. Wear adequate respiratory and skin protection.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Avoid release to the environment and contain any escaping gas using vent hoods or exhaust systems.
Cleanup Methods: Isolate source and allow gas to disperse with forced ventilation. Do not attempt to wash away with water due to reactivity. Use only trained personnel with specialized equipment.
Handling: Use only in closed systems or with appropriate ventilation. Always work with approved fume hoods, gas cabinets, or glove boxes. Do not allow contact with moisture—reacts corrosively.
Storage: Store cylinders upright, tightly closed, in a cool, dry, well-ventilated, and designated area away from incompatible substances. Keep storage temperature stable and avoid direct sunlight. Secure containers to prevent movement or accidental falls. Separate from acids, bases, oxidizers, and water-reactive materials.
Occupational Exposure Limits: ACGIH TLV: 2 ppm (TWA); OSHA PEL: 2 ppm (TWA)
Engineering Controls: Use local exhaust ventilation, explosion-proof equipment, and gas monitoring systems. Restrict access and maintain negative pressure in work zone.
PPE: Wear chemical goggles, face shield, impervious gloves (such as fluoropolymer or butyl rubber), flame-retardant lab coat or chemical apron, and positive-pressure respiratory protection if concentrations approach or exceed limits.
Hygiene Measures: Wash hands and face before eating, drinking, or smoking. Remove contaminated clothing and launder before reuse.
Appearance: Colorless gas
Odor: Sharp, suffocating
Molecular Weight: 66.01 g/mol
Melting Point: -136°C
Boiling Point: -83.1°C
Density: 1.14 g/L at 0°C
Solubility: Reacts with water; hydrolyzes to carbon dioxide and hydrofluoric acid
Vapor Pressure: 3310 mmHg at 20°C
Flammability: Not flammable under normal conditions
pH: Not applicable
Chemical Stability: Stable under dry, controlled conditions. Decomposes rapidly in presence of water or moisture.
Conditions to Avoid: Exposure to water, humid air, and open flames or high heat.
Incompatible Materials: Water, alcohols, strong bases, amines, alkali and alkaline earth metals. Carbonyl fluoride reacts vigorously, releasing toxic and corrosive fumes.
Hazardous Decomposition Products: Hydrofluoric acid, carbon monoxide, carbon dioxide, and other toxic vapors.
Likely Routes of Exposure: Inhalation is primary route; skin and eye contact pose acute risks
Acute Effects: High toxicity if inhaled — chief symptoms include severe irritation of respiratory tract, coughing, chest pain, difficulty breathing, pulmonary edema, and possible death.
Skin/Eye Damage: Severe burns, ulceration, and potential blindness
Chronic Effects: Repeated or prolonged exposure may damage lungs, liver, kidneys, and result in fluorosis (chronic fluoride poisoning).
Carcinogenicity: Not classified as a carcinogen by IARC, NTP, or OSHA.
Aquatic Toxicity: Hydrolysis produces hydrofluoric acid, very toxic to aquatic life.
Persistence and Degradability: Reacts rapidly with water, forming persistent and hazardous byproducts.
Bioaccumulation Potential: Fluorine compounds can accumulate in organisms.
Mobility in Soil: Forms acids that may leach and contaminate groundwater and soil.
Other Ecological Risks: Avoid release to the environment; toxic effects extend beyond immediate spill area.
Disposal Methods: Dispose of contents through licensed hazardous waste facilities. Neutralization and controlled incineration with proper scrubbers.
Container Handling: Empty containers retain product residue; do not puncture, cut, or incinerate. Return cylinders to supplier or follow institutional protocols.
Environmental Precautions: Keep chemicals and rinse water from contaminating soil, groundwater, and natural waterways.
