Weight Percent: 98% or greater
Impurities: Trace levels of heavy metals within regulated limits
Inhalation: Move to fresh air, keep warm, seek medical advice if symptoms like cough or irritation develop
Skin Contact: Remove any contaminated clothing, wash with plenty of running water and gentle soap, consult healthcare if redness or swelling persists
Eye Contact: Immediately rinse eyes with plenty of water for at least 15 minutes, lift eyelids occasionally to ensure thorough flushing, seek medical advice
Ingestion: Rinse mouth, drink water if conscious, do not induce vomiting, get urgent medical help if feeling unwell
Most Important Symptoms: Gastrointestinal upset, nausea, redness or irritation, respiratory discomfort
Medical Attention: Treat symptoms, monitor for delayed effects from zinc or sulfate exposure
Suitable Extinguishing Media: Use alcohol-resistant foam, dry chemical powder, or carbon dioxide for fires involving Zinc Sulfate
Unsuitable Media: Avoid use of water directly on powder, as runoff can contaminate environment
Hazards Arising: Material itself does not burn but can release toxic and irritating fumes including sulfur oxides, zinc oxides
Special Protective Equipment: Wear full protective clothing, self-contained breathing apparatus in fire area
Firefighting Advice: Stay upwind, avoid inhalation of smoke or fumes, use water spray to cool containers exposed to fire
Personal Precautions: Ensure appropriate ventilation, avoid dust formation, wear eye protection, NIOSH-approved respirator, gloves
Environmental Precautions: Prevent entry to waterways, drains, and soil, block off spill to avoid environmental contamination
Cleanup Methods: Sweep or scoop up without generating dust, collect in a dry clean container, avoid direct contact, dispose of according to local regulations
Reporting: Notify authorities if spill contaminates water sources or soil as required by law
Handling: Use only in well-ventilated areas, minimize dust production, handle with protective equipment for skin and eyes, avoid eating or drinking around the product
Storage: Store in original tightly closed container, keep in dry, cool, well-ventilated area, keep away from acids, strong reducing agents, and food items
Specific Practices: Label containers clearly, restrict access in storage area to authorized personnel
Occupational Exposure Limits: ACGIH TLV for Zinc Sulfate (as zinc): 2 mg/m3 (respirable fraction)
Engineering Controls: Use local exhaust ventilation, especially where dust may form
Personal Protective Equipment: Use chemical-splash goggles, chemical-resistant gloves, NIOSH-approved particulate respirator, protective lab coat or coveralls
