SECTION 4: First-Aid Measures
Inhalation: Move exposed person to fresh air. If breathing is difficult, administer oxygen and consult a physician.
Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing. Wash with soap and water.
Eye Contact: Flush immediately with copious amounts of clean water for at least 15 minutes holding eyelids open. Seek urgent medical attention.
Ingestion: Never give anything by mouth to an unconscious person. Rinse mouth thoroughly. Do NOT induce vomiting. Seek immediate medical advice.
SECTION 5: Fire-Fighting Measures
Suitable Extinguishing Media: Water spray, carbon dioxide, dry chemical powder, or alcohol-resistant foam.
Hazardous Combustion Products: Oxides of carbon, nitrogen oxides (NOx), and oxides of phosphorus (PxOy).
Protective Equipment: Firefighters must wear full protective chemical gear and self-contained breathing apparatus (SCBA).
SECTION 6: Accidental Release Measures
Personal Precautions: Wear suitable protective equipment (gloves, safety goggles, apron). Avoid direct contact.
Environmental Precautions: Prevent entry into drains, sewers, or natural waterways.
Clean-Up Methods: Neutralize spill cautiously with dilute alkali (sodium carbonate/lime), absorb with sand or clay, and place into marked chemical waste containers.
SECTION 7: Handling and Storage
Handling: Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Wash thoroughly after handling.
Storage: Store in original tightly sealed HDPE containers in a cool, dry, well-ventilated warehouse away from direct sunlight, strong alkalis, and oxidizing agents.
SECTION 8: Exposure Controls / Personal Protection
Engineering Controls: Provide mechanical local exhaust ventilation to maintain low airborne concentrations.
Personal Protective Equipment (PPE):
- Eye/Face Protection: Tightly fitting chemical splash safety goggles and face shield.
- Skin Protection: Neoprene or nitrile rubber chemical resistant gloves and impervious protective suit.
- Respiratory Protection: Use suitable respiratory protective equipment if mist or aerosol is generated.
