Inhalation: Move to fresh air. If breathing is difficult, seek medical advice immediately. Administer oxygen if available and qualified to do so. Remove any contaminated clothing near mouth and nose.
Skin Contact: Wash skin with soap and plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Get medical attention if irritation persists or rash develops.
Eye Contact: Rinse immediately with plenty of water for several minutes, lifting eyelids to ensure thorough flushing. Seek medical attention if symptoms occur.
Ingestion: Rinse mouth with water but do not induce vomiting. Do not give anything by mouth to an unconscious person. Seek medical attention or call poison control center.
Important Symptoms: Skin redness, itching, nausea, respiratory discomfort, possible headache and dizziness on exposure
Suitable Extinguishing Media: Use dry chemical, foam, carbon dioxide, or water spray.
Unsuitable Extinguishing Media: High volume water jet as it may spread or intensify fire risk.
Special Fire Hazards: Decomposition under fire produces sulfur oxides, nitrogen oxides, carbon oxides, zinc oxide fumes, and toxic gases.
Protective Equipment: Firefighters must wear self-contained breathing apparatus and full protective clothing.
Advice for Firefighters: Keep containers cool with water spray to prevent rupture, avoid runoff into water drains, control spread of material.
Personal Precautions: Evacuate non-essential personnel, ventilate area, avoid dust formation, use protective equipment including gloves, goggles, and respirator.
Environmental Precautions: Prevent spill from entering sewers, waterways, or soil, notify authorities in case of significant release.
Containment and Cleanup: Sweep up spills using non-sparking tools, collect in suitable closed containers for disposal, avoid generating dust, clean area thoroughly with water after material is picked up.
Handling: Handle in well-ventilated location, avoid breathing dust, wash hands and exposed skin after use, do not eat, drink or smoke while handling product, avoid contact with eyes and skin.
Storage: Store in tightly closed container, keep in a cool, dry, and well-ventilated area, keep away from strong acids, oxidizers, direct sunlight, and moisture, segregate from incompatible substances, store away from feed and foodstuffs, ensure proper labeling.
Exposure Limits: ACGIH TLV: 0.5 mg/m³ (as Ziram), OSHA PEL: Not established specifically for this compound
Engineering Controls: Local exhaust ventilation to control airborne concentrations, regular air monitoring
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), goggles or face shield, long-sleeved lab coat, dust mask or respirator with approved filter (N95 or better), protective boots if necessary
