First Aid Measures

Inhalation: Move person into fresh air. Offer oxygen if breathing is difficult. Seek medical attention right away for symptoms.
Skin Contact: Rinse skin with large amounts of water. Remove contaminated clothing and shoes immediately. Wash affected area for at least 15 minutes. Don’t reuse contaminated clothing until laundered.
Eye Contact: Immediately flush eyes with plenty of water, lifting upper and lower eyelids occasionally. Remove contact lenses if present and easy to do. Continue rinsing for at least 15 minutes. Seek urgent medical attention.
Ingestion: Rinse mouth. Do not induce vomiting. Never give anything by mouth to an unconscious person. Seek immediate medical advice for possible burns or other harm.

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, dry chemical, CO₂, foam. Avoid using strong streams as product dissolves and spreads.
Specific Fire Hazards: Decomposes upon heating, releasing toxic gases such as chlorine, phosphorus oxides, and sodium oxides.
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear.
Special Procedures: Cool unaffected containers with water spray to prevent bursting. Prevent run-off from contaminating soil and water bodies.

Accidental Release Measures

Personal Protections: Put on protective gear including goggles, gloves, and chemical-resistant clothing.
Environmental Precautions: Keep spills out of watercourses, storm drains, or soil. Notify proper authorities if product enters environment.
Methods for Cleanup: Sweep up and place in a suitable, properly labeled container for disposal. Neutralize remaining traces with dilute acid, if safe to do. Wash spill area with plenty of water.

Handling and Storage

Handling: Use only in well-ventilated areas. Do not inhale dust, vapors, or mist. Wear appropriate personal protective equipment at all times. Wash hands before eating, drinking, or smoking.
Storage: Store in tightly closed containers in a cool, dry, and well-ventilated place. Keep away from acids, reducing agents, and combustible materials. Do not store above 40°C. Keep away from children and unauthorized personnel.
Incompatible Materials: Acids, organic materials, ammonium compounds, and oxidizing or reducing agents.

Exposure Controls and Personal Protection

Occupational Exposure Limits: TLV (Threshold Limit Value) for phosphate compounds: 5 mg/m³ TWA (ACGIH)
Engineering Controls: Use local exhaust or general ventilation to maintain airborne levels below applicable limits.
Personal Protective Equipment: Protective clothing, chemical-resistant gloves, safety goggles, and face shield for potential splashes. Respiratory protection if dust/vapor exceeds exposure limits.
Hygiene Controls: Wash hands and face after handling and before meals. Wash contaminated clothing before reuse. Prohibit eating or drinking in work area.
