Impurities / Additives: Trace impurities not contributing to classification. No significant additives.
Inhalation: Remove to fresh air. If breathing is difficult, seek medical attention. Provide oxygen if available and trained to use.
Skin Contact: Rinse skin with water for at least 15 minutes. Take off contaminated clothing and wash before reuse.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing and get medical attention.
Ingestion: Rinse mouth. Do not induce vomiting. Seek immediate medical care.
Most Important Symptoms: Burning sensation, coughing, nausea, vomiting, shortness of breath, irritation or redness to skin and eyes.
Special Notes for Doctor: Treat symptomatically; monitor for respiratory distress.
Suitable Extinguishing Media: Flood fire with water. Dry chemical or carbon dioxide not effective. Do not use dry combustibles like sawdust.
Specific Hazards: Oxidizer, enhances combustion of other materials. Releases irritating or toxic fumes (nitrogen oxides, zinc oxides) in fire.
Protective Equipment: Firefighters need full protective clothing and self-contained breathing apparatus.
Specific Methods: Move containers from fire area if possible. Use water spray to cool exposed containers. Contain water runoff; prevent from entering sewers.
Explosion Hazard: Not explosive, but contact with combustibles increases fire risk.
Personal Precautions: Evacuate unnecessary personnel. Ventilate area. Wear appropriate personal protective equipment (PPE), including gloves, goggles, and respiratory protection.
Spill Cleanup Methods: Collect solid material using non-combustible absorbent such as sand or vermiculite. Avoid dry sweeping. Shovel into suitable container for salvage or disposal.
Environmental Protection: Prevent spillage from entering drains, surface or groundwater. Notify local environmental authorities if large spill threatens the environment.
Disposal: Dispose in accordance with local, regional, national, and international regulations.
Handling: Avoid breathing dust or fumes. Handle in well-ventilated area. Use proper PPE. Avoid contact with skin, eyes, and clothing. Remove contaminated clothing before leaving the work area.
Storage: Store in tightly closed container in cool, dry, ventilated area away from combustible or reducing materials. Separate from strong acids, organic materials, and bases. Prevent container damage and label properly.
Incompatible Materials: Reducing agents, organic substances, combustible materials such as paper, wood, or oil.
Special Rules: Use dedicated chemical storage options for oxidizers. Keep storage area equipped with emergency eyewash and shower fixtures.
Exposure Limits: OSHA, ACGIH, and NIOSH Occupational Exposure Limits not specifically assigned to zinc nitrate; use general soluble zinc compounds: TWA 2 mg/m3 (as Zn).
Engineering Controls: Local exhaust ventilation, system enclosure, process isolation.
Personal Protective Equipment: Protective gloves (nitrile, PVC), chemical splash goggles or safety glasses, lab coat or apron. Respiratory protection with NIOSH/MSHA-approved respirator if dust or mist forms during use.
General Hygiene: Do not eat, drink, or smoke during use. Wash hands thoroughly after handling. Remove PPE before leaving worksite.

Chemical Stability: Stable under normal storage conditions in closed containers.
Reactivity: Reacts with organic and easily oxidized substances. Incompatible with reducing agents, phosphorous, and combustibles.
Hazardous Decomposition Products: Nitrogen oxides, zinc oxide fumes
Hazardous Polymerization: Will not occur under normal handling
Conditions to Avoid: Heat, flame, ignition sources, incompatible materials, moisture
Acute Toxicity: Ingestion may cause burning in mouth and throat, abdominal pain, nausea, and vomiting. May cause systemic zinc toxicity, disrupting multiple body systems.
Inhalation: Exposure irritates respiratory tract. Symptoms include coughing, shortness of breath.
Skin Contact: Can cause irritation, redness, and pain after prolonged or repeated contact.
Eye Contact: Risk of serious eye irritation with redness, pain, possible corneal injury.
Chronic Effects: Prolonged or repeated exposure may cause dermatitis, respiratory irritation, zinc accumulation.
Carcinogenicity: Not classified as carcinogen by IARC, NTP or OSHA.
Mutagenicity: Not reported as genetically active.
Reproductive Toxicity: No evidence for reproductive effects in humans.
Ecotoxicity: Toxic to aquatic organisms, may cause long-term adverse effects in aquatic environment. Zinc and nitrate ions both contribute to waterway impact.
