Skin Contact: Remove contaminated clothing and rinse skin thoroughly with water for at least 15 minutes. Seek medical attention if irritation develops or persists.
Eye Contact: Rinse cautiously with water for several minutes, removing contact lenses if present and easy to do. Get medical advice as soon as possible; treat as a chemical burn.
Ingestion: Rinse mouth, do not induce vomiting. Seek urgent medical attention. Monitor for signs of toxicity such as nausea, headache, or abdominal pain.
Important Symptoms: Burning, redness, swelling of skin and eyes, difficulty in breathing, nausea, convulsions at significant exposure.
Suitable Extinguishing Media: Foam, dry powder, carbon dioxide—water spray for larger fires. Avoid water jets which may spread the substance.
Specific Hazards: Thermal decomposition forms corrosive and/or toxic fumes of hydrogen chloride, phosphorus oxides, and possibly chlorinated organic compounds.
Protective Equipment: Firefighters should wear full body protective clothing with self-contained breathing apparatus while approaching fires involving this chemical.
Special Procedures: Cool containers with water spray to prevent explosions from heat. Avoid runoff into sewers and waterways.
Personal Precautions: Evacuate non-essential personnel, wear full personal protective equipment including respiratory protection, avoid contact with skin and eyes.
Environmental Precautions: Contain the spill to prevent release into drains, surface and groundwater due to potential toxicity to the aquatic environment.
Methods for Containment: Absorb with inert material (Earth, sand, vermiculite).
Clean-up Procedures: Collect spilled material in containers for proper disposal, ventilate area, wash spill site after material pickup is complete.
Notification: Report large releases to appropriate regulatory authorities.
Handling: Handle in a well-ventilated area, wear chemical-resistant gloves and goggles, avoid inhalation of vapors and contact with skin, wash hands before eating or drinking.
Storage: Keep containers tightly closed in a cool, dry, well-ventilated area away from incompatible materials such as strong acids, oxidizers, and bases; keep away from sources of ignition or heat.
Incompatibilities: Avoid mixing with strong acids, strong bases, or oxidizing agents.
Storage Conditions: Store in corrosion-resistant containers with chemical-resistant liners.
Occupational Exposure Limits: No formal regulatory threshold limits, follow recommended practices to minimize airborne concentrations.
Engineering Controls: Use ventilation systems, fume hoods, or closed handling systems to maintain airborne levels below detectable limits.

Reactivity: Reacts with strong acids, bases, and oxidizing agents, leading to hazardous decomposition.
Hazardous Decomposition Products: Hydrogen chloride, phosphoric acid, chlorine oxides, carbon monoxide, and various volatile chlorinated organic compounds.
Conditions to Avoid: Prolonged heat, direct sunlight, open flames, sources of ignition.
Polymerization: Not known to undergo dangerous polymerization.
Acute Toxicity: Oral LD50 (rat) ~ 300 mg/kg, Dermal LD50 ~ 600 mg/kg, Inhalation may be toxic but little vapor forms under typical industry conditions.

Sensitization: May trigger allergic reactions in some users.
Other Health Effects: Central nervous system depression, loss of coordination, headaches, nausea at high doses.
Ecotoxicity: Highly toxic to aquatic organisms including fish and invertebrates with long-lasting effects, demonstrated in laboratory and real-world spill events.
Mobility: Shows low to moderate mobility in soil depending on rainfall and soil composition.
Persistence and Degradability: Degrades slowly in water and soil, stable under acidic to neutral pH, hydrolysis occurs faster at higher pH.
Bioaccumulation: Evidence suggests moderate bioaccumulation potential in aquatic species, affecting local food webs.
Environmental Fate: Risk of contaminating groundwater if improperly disposed or spilled.
Waste Treatment Methods: Any waste or contaminated packaging must be incinerated in approved chemical waste facilities with proper emission controls for halogenated organics and phosphorus compounds.
