Symptoms: Irritation, coughing, redness, discomfort, zinc fume fever if inhaled in large amounts
Suitable Extinguishing Media: Water spray, dry powder, carbon dioxide, foam
Specific Hazards: Zinc oxide itself is not flammable, but fine powder can create explosive dust-air mixtures
Protective Equipment: Wear self-contained breathing apparatus, full protective gear
Thermal Decomposition: May emit zinc fumes above 1975°C, avoid inhaling decomposition products
Personal Precautions: Wear dust mask, gloves, safety goggles, avoid dust formation, ensure adequate ventilation
Spill Cleanup: Sweep up, avoid creating dust clouds, collect in tightly closed containers for proper disposal
Environmental Precautions: Prevent material from entering water systems, drains, soil
Disposal: Coordinate with approved waste handlers familiar with hazardous inorganic chemicals
Handling: Use only in well-ventilated areas, employ local exhaust to minimize dust, avoid direct contact, do not eat, drink, or smoke while using product
Storage Conditions: Keep container tightly sealed, store in dry, cool, well-ventilated location, away from incompatible substances such as acids
Special Precautions: Segregate from reactive chemicals, label containers accurately, use appropriate dust controls
Exposure Limits: OSHA PEL: 5 mg/m³ (respirable dust), ACGIH TLV: 2 mg/m³ (respirable fraction, TWA)
Engineering Controls: Use local exhaust ventilation, enclosure of processes as feasible
Personal Protection: Dust mask/respirator approved for particulates, chemical-splash goggles, gloves, laboratory coat or protective clothing
Hygiene Measures: Wash hands thoroughly after handling, remove contaminated clothing before eating, maintain clean workplace
