Hazard Classification: Oxidizing agent, toxic, harmful on contact or inhalation
GHS Label Elements: Danger symbol, oxidizer pictogram, acute toxicity exclamation
Signal Word: Danger
Hazard Statements: May intensify fire, toxic if swallowed or inhaled, causes severe skin burns and eye damage, can cause adverse effects to blood and cardiovascular system, risk of explosion due to powerful oxidizer properties
Precautionary Statements: Keep away from heat or ignition sources, avoid breathing dust or fumes, wear protective equipment, wash thoroughly after handling, use only outdoors or in well-ventilated area
Chemical Name: Hydroxylamine Nitrate
Concentration: Typically 98–100% pure when purchased for laboratory or synthesis use
Impurities: Trace amounts of water, trace metal impurities possible from manufacturing process
Molecular Weight: 96.05 g/mol
Eye Contact: Flush immediately with plenty of water for at least 15 minutes, hold eyelids open, remove contact lenses if present, seek urgent medical attention
Skin Contact: Remove contaminated clothing, rinse skin thoroughly with water and soap, do not attempt to neutralize, seek medical attention right away
Inhalation: Relocate person to fresh air, keep comfortable, provide oxygen support if breathing is labored, seek urgent medical care
Ingestion: Rinse mouth with water if person is conscious, do not induce vomiting, do not attempt to give anything by mouth if unconscious, seek immediate medical help
Most Critical Symptoms/Effects: Severe burns, breathing problems, nausea, headache, blood changes, risk of methemoglobinemia
Note to Physician: Monitor for delayed effects, support blood oxygen capacity, symptomatic treatment
Suitable Extinguishing Media: Flooding with water, avoid dry chemical or carbon dioxide. Do not use foam.
Hazards from Combustion: Releases toxic nitrogen oxides, ammonia, possible explosive pressure buildup
Special Protective Equipment: Firefighters must wear self-contained breathing apparatus and fully protective chemical-resistant suit
Additional Advice: Evacuate area, cool containers with flooding quantities of water from safe distance, keep away from sources of fuel and reducing agents, avoid inhaling fumes
Personal Precautions: Avoid contact, wear chemical-resistant gloves, goggles, full protective clothing, respiratory protection
Spill Response: Evacuate area, isolate leak, prevent spillage from entering drains, soak up with inert absorbent (vermiculite or sand), collect in suitable container for disposal
Environmental Precautions: Prevent release into environment, especially waterways, notify relevant authorities immediately if large spill occurs
Decontamination: Wash spill area thoroughly with copious water after initial cleanup is complete, ventilate the affected area
Safe Handling: Ensure handling only by trained personnel in well-ventilated areas, avoid rough handling, do not mix with fuels or reducing materials, never return unused product to original container
Storage Requirements: Store in tightly sealed corrosion-resistant containers in cool, dry, well-ventilated place, away from direct sunlight, heat, and incompatible substances (works best in isolated chemical storage, not near any organic materials, combustibles, reducing agents)
Incompatible Materials: Metals, strong bases, acids (other than nitric), combustibles, sulfur, phosphorus, organic solvents
Special Precautions: Regularly inspect storage containers, have emergency plan available for leaks, accidental release, or fire
Occupational Exposure Limits: ACGIH TLV: Not established, but minimize all exposure due to toxicity
Engineering Controls: Use only with chemical fume hood, ensure explosion-proof ventilation systems
Respiratory Protection: NIOSH/MSHA-approved respirator if airborne concentrations risk exceeds safety protocol, self-contained breathing apparatus for high concentrations
Eye/Face Protection: Chemical splash goggles plus face shield
Skin Protection: Chemical-resistant gloves (nitrile or neoprene), full body suit, chemical safety boots
Hygiene Measures: Always wash exposed skin and remove contaminated clothing, avoid eating or drinking anywhere near handling areas
Appearance: White to off-white crystalline solid

Partition Coefficient: Not readily partitioned, stays in aqueous phase
Decomposition Temperature: May decompose violently above 80°C or in presence of incompatible substances
Chemical Stability: Stable only under recommended storage conditions, unstable when contaminated or heated
Reactivity: Strong oxidizer, reacts violently with reducing agents, fuels, metals
Hazardous Reactions: Explosive mixtures possible with combustible substances, fast release of heat and gases
Incompatible Materials: Includes organic materials, metals, combustibles, strong bases, sulfur, phosphorus, reducing agents
Hazardous Decomposition Products: Nitrogen oxides, ammonia, water vapor, nitrous oxide
Routes of Exposure: Inhalation, ingestion, dermal, ocular
Acute Effects: Severe burns on skin and mucous membranes, respiratory distress, potentially fatal in high exposures
Chronic Effects: Methemoglobinemia, blood and kidney toxicity, neurotoxicity on longer exposure
Symptoms: Cough, shortness of breath, nausea, dizziness, collapse
Toxicity Data: LD50 oral (rat): approx. 80 mg/kg
Carcinogenicity: Not listed by IARC, NTP, or OSHA as carcinogen
Sensitization: Not reported as sensitizer
Aquatic Toxicity: Highly toxic to aquatic organisms, causes long-lasting changes in aquatic systems
Environmental Mobility: Highly soluble in water, likely to penetrate soil rapidly and reach groundwater
Persistence/Degradability: May persist and alter soil or surface water chemistry
Bioaccumulation: Not expected to bioaccumulate in aquatic life
Hazard to Plants and Animals: Damages aquatic flora and fauna, disrupts nitrogen cycle
Disposal Methods: Handle as hazardous waste under local regulations, incinerate at licensed chemical incinerator only, do not allow to reach sewers or waterways
Container Considerations: Decontaminate containers by rinsing with copious amounts of water, neutralize residues with care, recycle or discard according to official protocols
Waste Codes: Contact local hazardous waste authority for classification
