SECTION 4 First Aid Measures

Eye Contact	Rinse cautiously with plenty of water for at least 15 minutes. Remove contact lenses if present and easy to do. If irritation persists, seek medical attention.
Skin Contact	Wash affected area thoroughly with mild soap and water. Remove contaminated clothing. No known dermal hazard; rinse for comfort.
Inhalation	Move to fresh air immediately. If breathing is difficult, administer oxygen. If symptoms persist, seek medical advice.
Ingestion	Rinse mouth thoroughly with water. Drink 1–2 glasses of water to dilute. Do NOT induce vomiting unless directed by medical personnel. Consult a physician if large quantities are ingested.
Most Important Symptoms	No acute symptoms expected. Dust may cause transient mechanical eye or throat irritation.
Notes to Physician	Treat symptomatically. No specific antidote required.

SECTION 5 Firefighting Measures

Flammability	Non-flammable. The substance itself does not burn.
Thermal Decomposition	Decomposes at 250–350°C, releasing water vapor (endothermic reaction): 2 Al(OH)₃ → Al₂O₃ + 3 H₂O ↑
Suitable Extinguishing Media	Water spray, alcohol-resistant foam, dry chemical, carbon dioxide (CO₂). Select media appropriate for surrounding fire.
Unsuitable Extinguishing Media	None specific. Avoid high-pressure water jet that may create dust clouds.
Special Hazards	No hazardous decomposition products other than water vapor under normal fire conditions. Alumina (Al₂O₃) residue remains.
Special Protective Equipment	Wear self-contained breathing apparatus (SCBA) and full protective gear in confined or heavily smoke-filled areas.

SECTION 6 Accidental Release Measures

Personal Precautions	Avoid generation and inhalation of dust. Use appropriate personal protective equipment (see Section 8). Ensure adequate ventilation.
Environmental Precautions	Avoid discharge into drains, surface water, or groundwater. Spilled product is not classified as hazardous to the environment but may cause physical fouling of waterways.
Containment & Cleanup	Collect mechanically using vacuum (with HEPA filter) or by damp sweeping to minimize dust. Transfer into labeled, sealable containers for disposal or recovery. Avoid dry sweeping that generates airborne dust.

SECTION 7 Handling and Storage

Safe Handling	Use in well-ventilated areas. Minimize dust generation and accumulation. Practice good housekeeping. Wash hands thoroughly after handling.
Storage Conditions	Keep containers tightly sealed and in a dry environment. Recommended storage temperature: 5–35°C. Protect from moisture and humidity to prevent caking. Store away from strong acids and strong alkalis (exothermic reaction possible).
Packaging Materials	PE-lined paper bags, FIBC (big bags), or sealed containers. Avoid unlined paper in high-humidity environments.

SECTION 8 Exposure Controls / Personal Protection

Occupational Exposure Limit	TLV-TWA: 10 mg/m³ (inhalable particulate, as Al) ACGIH TLV: 1 mg/m³ (respirable fraction, as Al) OSHA PEL: 15 mg/m³ (total dust); 5 mg/m³ (respirable fraction)
Engineering Controls	Use local exhaust ventilation at points of dust generation. General dilution ventilation is acceptable under normal conditions.
Respiratory Protection	Wear a dust mask (e.g., EN 149 FFP2 / NIOSH N95 or better) when exposure limits may be exceeded or dust is visible in air.
Eye Protection	Wear safety goggles (EN 166 or ANSI Z87.1) to prevent mechanical irritation from dust.
Skin Protection	Protective gloves (cotton, nitrile, or leather). Long-sleeved clothing. No special dermal hazard, but gloves recommended for comfort.
Hygiene Measures	Wash hands and face before breaks and after work. Do not eat, drink, or smoke in work areas. Eye-wash stations recommended.
