Inhalation: Move person to fresh air immediately. Administer oxygen if breathing is difficult. Avoid direct contact with vapors. Seek medical attention as soon as possible.
Skin Contact: Remove contaminated clothing. Rinse skin thoroughly with water for at least 15 minutes. Use soap where possible. Immediately seek medical help.
Eye Contact: Rinse cautiously with water for at least 15 minutes, making sure eyelids are held open. Remove contact lenses if present and easy to do. Seek urgent medical attention.
Ingestion: Do not induce vomiting. Rinse mouth with water. Do not give anything to drink to an unconscious person. Contact a poison control center or physician immediately.
Suitable Extinguishing Media: Dry chemical, carbon dioxide (CO2), foam. Use water spray to cool containers, but do not direct water at the leak or spill.
Unsuitable Extinguishing Media: Avoid use of direct water stream as it may spread the chemical.
Hazards from Combustion: Produces toxic vapors such as hydrochloric acid, phosphorus oxides, benzene derivatives when heated or burned.
Protective Equipment: Full protective gear and self-contained breathing apparatus required for fire fighters. Remain upwind.
Fire-Fighting Instructions: Remove all persons from fire area who do not need to be there. Prevent run-off from entering drains or waterways. Approach from upwind and avoid smoke exposure.
Personal Precautions: Wear chemical protective clothing, gloves, and goggles. Use self-contained breathing apparatus for large spills or if ventilation is inadequate. Evacuate non-essential personnel.
Environmental Precautions: Prevent leaks or spills from entering drains, surface water, or soil. Notify local authorities if material enters public sewers or waterways.
Cleanup Methods: Use inert absorbent material such as vermiculite or sand to collect spilled material. Place in labeled chemical waste containers for safe disposal. Ventilate area thoroughly after cleanup.
Decontamination: Wash affected area with large volumes of water. Avoid using water directly on spill as it may produce corrosive fumes.
Disposal: Dispose of residues according to local, state, and federal requirements for hazardous wastes.
Handling: Avoid breathing vapors or fumes. Always handle chemical in a fume hood or well-ventilated workspace. Do not allow contact with water or moist air. Use appropriate personal protection at all times. Never eat, drink, or smoke during use.
Storage: Store in tightly closed containers made of compatible materials. Keep in a cool, dry, well-ventilated area away from incompatible substances such as water, strong bases, oxidizing agents, and alcohols. Keep away from heat, sparks, and source of ignition.
Special Precautions: Label containers clearly. Limit access to authorized personnel trained in chemical handling. Regularly inspect container integrity.
Permissible Exposure Limits: No established OSHA PEL or ACGIH TLV for this specific material. Minimize exposure by technical controls.
Engineering Controls: Use chemical fume hood, local exhaust ventilation where possible. Regularly inspect ventilation systems.
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), full-face splash goggles, long-sleeve lab coat, closed footwear, and face shield where splash risk exists.
Respiratory Protection: Use NIOSH-approved respirator for organic vapors in poorly ventilated areas or during spill response.
Hygiene Measures: Wash hands thoroughly with soap and water before eating or using restroom. Remove contaminated clothing before leaving work area.
Appearance: Colorless to pale yellow liquid
Odor: Sharp, acrid, irritating
Odor Threshold: Not determined
pH: Strongly acidic upon contact with water
Melting Point: -3°C
Boiling Point: 258°C at atmospheric pressure
Flash Point: 132°C (closed cup)
Evaporation Rate: Not rapid under ambient conditions
Flammability: Not classified as highly flammable, but may ignite under certain conditions
Vapor Pressure: Low at room temperature
Vapor Density: Heavier than air
Relative Density: 1.4-1.6 g/cm³
Solubility: Reacts violently with water, decomposing and releasing hydrochloric acid
Partition Coefficient: Not established
Auto-Ignition Temperature: Data not available
Decomposition Temperature: Emits toxic fumes over 150°C
Viscosity: Moderate
Molecular Weight: 210 g/mol
Chemical Stability: Stable under recommended storage conditions, but decomposes in presence of moisture
Potential Hazardous Reactions: Reacts violently with water, strong bases, and alcohols. Reaction releases hydrochloric acid and heat.
Conditions to Avoid: Contact with water, humid air, heat, flame, and incompatible materials. Prolonged exposure to air increases risk of hydrolysis.
Incompatible Materials: Water, bases, oxidizing agents, alcohols and amines. Contact with these produces toxic fumes and heat.
Hazardous Decomposition Products: Hydrogen chloride gas, phosphorus oxides, benzene derivatives under combustion or hydrolysis.
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Toxicity: Causes severe irritation and chemical burns to eyes, skin, and respiratory tract. Inhalation can trigger coughing, shortness of breath, and possible pulmonary edema.
LD50 Oral (rat): Reported as 180 mg/kg
LD50 Dermal (rabbit): Not precisely established, but severe burns documented
Chronic Effects: Long-term exposure may result in dermatitis, respiratory sensitization or chronic respiratory distress.
Carcinogenicity: No classification by IARC, OSHA, or NTP
Other Effects: May aggravate pre-existing respiratory, skin, or eye conditions. No evidence reported for genotoxicity or reproductive toxicity from available data.
Symptoms: Burning sensation, pain, redness, swelling, trouble breathing, ulceration if left untreated.
Ecotoxicity: Highly toxic to aquatic organisms by rapid hydrolysis and formation of acidic byproducts. LC50 values for fish and aquatic invertebrates indicate high hazard at low concentrations, though degradation happens fast in nature.
Persistence and Degradability: Hydrolyzes rapidly on contact with moisture, forming phenylphosphonic acid and hydrochloric acid
Bioaccumulative Potential: Not likely to bioaccumulate given rapid breakdown in aqueous environments
Mobility in Soil: Limited due to rapid reaction with water and organic matter in soil
Other Adverse Effects: Acidic hydrolysis products can alter water pH, impact aquatic species, and damage vegetation near release points.
Disposal Methods: Treat all waste as hazardous. Do not pour down drains or sewers. Collect and store waste residues in tightly sealed, labeled containers for pickup by certified hazardous waste disposal contractor.
Contaminated Packaging: Rinse empty containers with sodium bicarbonate solution under controlled conditions before disposal, then triple rinse with water. Dispose of packaging under state and federal hazardous waste regulations.
Incineration: Only in legally permitted facilities equipped for halogenated waste
Precautions: Wear personal protective equipment throughout disposal process. Avoid breathing vapors or fumes generated from waste.
