Inhalation: Remove to fresh air, support breathing as necessary, consult a doctor if symptoms persist
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, seek medical attention for irritation
Eye Contact: Rinse thoroughly with water for several minutes, remove contact lenses, continue rinsing, seek medical attention for redness or pain
Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical attention, show SDS to medical personnel
Most Important Symptoms: Coughing, redness or irritation of skin and eyes, allergic reactions such as rash
Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Specific Hazards During Fire: Releases toxic gases including phosphoryl chloride and nitrogen oxides, may form corrosive fumes
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective suit
Advice for Firefighters: Cool adjacent containers with water spray, avoid water run-off entering drains or water courses
Special Procedures: Stay upwind, evacuate area if large fire or uncontrolled release
Personal Precautions: Wear gloves, boots, chemical-resistant apron, and goggles, avoid inhalation of vapors
Environmental Precautions: Block entry to sewers, storm drains, or natural waterways using absorbent barriers
Cleanup Methods: Use inert absorbent material (e.g., sand, earth), scoop up and place in labeled waste container
Emergency Procedures: Ventilate enclosed spaces, report significant spills to local authorities, dispose of waste as hazardous material
Decontamination: Wash area with plenty of water and detergent, ventilate and monitor for odor or residue
Handling: Avoid skin and eye contact, prevent inhalation of dust or spray, use only with adequate local ventilation
Storage: Keep container tightly closed in a cool, dry, well-ventilated place, protect from sunlight and heat sources
Incompatible Materials: Oxidizing agents, strong acids, strong bases
Storage Containers: Use chemical-resistant, clearly labeled containers, keep away from food, drinks, and animal feed
Specific Use(s): Meant for use in controlled industrial environments, not for consumer applications
Engineering Controls: Local exhaust ventilation at application and mixing points, eye-wash stations and safety showers in work area
Occupational Exposure Limits: Tetrakis(hydroxymethyl)phosphonium chloride: 2 mg/m3 TWA (manufacturer recommendation)
Personal Protection: Chemical-resistant gloves, safety goggles, long-sleeved work clothing, appropriate respiratory protection for mist or spray
Hygiene Measures: Wash hands after handling, remove contaminated clothing before breaks or leaving work area
Environmental Controls: Ensure waste water from processing passes through treatment system before discharge
Appearance: Clear to pale yellow liquid

Hazardous Reactions: Reacts with strong oxidizing agents, may give off toxic fumes if mixed with acids or bases
Decomposition Products: Phosphine, nitrogen oxides, hydrochloric acid fumes in fire or extreme conditions
Polymerization: Not known to polymerize under normal industrial conditions
Acute Toxicity: Oral LD50 (rat): 150–300 mg/kg
Skin Irritation: May cause redness, dryness, or swelling with prolonged contact
Eye Damage: Direct contact can lead to pain, serious irritation, and potential corneal injury
Inhalation: Overexposure to mist can result in respiratory tract irritation
Chronic Effects: May cause sensitization or allergic reaction in some individuals with repeated skin exposure
Carcinogenicity: Not classified as carcinogenic by IARC, OSHA, or NTP
Eco-toxicity: Harmful to aquatic life with long-lasting effects, especially freshwater invertebrates
Mobility: Readily disperses in water, may travel considerable distances from spill site
Persistence and Degradability: Slow biodegradation in soil and water, chemical tends to persist in the environment
Bioaccumulation: Low potential for buildup in fish, but concern for repeated exposure in local ecosystems
Aquatic Toxicity: EC50 Daphnia magna: 28 mg/L over 48 hours
Disposal Methods: Dispose as hazardous chemical waste in accordance with local, regional, and federal regulations
Waste Packaging: Triple rinse containers, puncture and send to a licensed recycler or disposal facility
Incineration: Thermal treatment in controlled facilities to break down organic content
Sewage Disposal: Do not allow wash water or spills into sewer systems without appropriate treatment
