Impurities and Stabilizing Additives: Minor traces of sodium chloride as byproduct, no significant impact to hazard
Inhalation: Remove to fresh air immediately, support breathing if symptoms develop, contact a physician
Eye Contact: Rinse eyes carefully with water for 15 minutes, lift upper and lower eyelids, seek medical attention
Skin Contact: Remove contaminated clothing, wash exposed area with soap and water generously, medical care if symptoms persist
Ingestion: Rinse mouth, do not force vomit, call poison control or medical help at once, provide water if conscious
Most Important Symptoms: Eye pain, redness or blurred vision, coughing, burning sensation in throat or nose, abdominal pain if ingested
Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, alcohol-resistant foam, do not use water streams on surrounding chemical fires
Fire Hazards: Releases toxic fumes of nitrogen oxides, sulfur oxides, hydrochloric acid and chlorine, also risks sodium oxide ash
Specific Protective Actions: Firefighters put on self-contained breathing apparatus and wear full protective gear, cool exposed containers with water spray
Explosion Data: Not explosive under normal handling, may intensify fire with reactive agents
Further Advice: Remove personnel from area, ensure adequate ventilation after fire extinguishes
Personal Precautions: Wear gloves, chemical goggles, long sleeves and respirator as needed
Environmental Precautions: Prevent entry into drains, waterways and soil, isolate spill with diking as necessary
Cleanup Methods: Scoop or sweep solid material into appropriate chemical-waste container, ventilate affected area, wash spill site after removal
Other Advice: Use non-sparking or anti-static tools, avoid dust formation while cleaning
Handling: Keep container tightly sealed, open containers with care under local ventilation, minimize breathing in dust, avoid touch with skin or eyes, restrict access to trained individuals only
Storage: Place in cool, dry, well-ventilated space well apart from acids or reducing agents, keep away from moisture and incompatible materials, label containers clearly and keep away from food or drink
Storage Temperature: Store between 2°C and 8°C prevents decomposition, protect from sunlight and strong light sources
Packaging Materials: Use high-density polyethylene, glass, or compatible chemical-resistant drums
Occupational Exposure Limits: No specific OSHA or ACGIH values, minimize inhalation and contact at all times
Engineering Controls: Work in chemical fume hood or local exhaust system
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), splash-proof goggles, lab coat, respirator with P2 particulate filters if dust risk present
Other Protection: Eye-wash stations and safety showers required close to work site, wash hands before eating or drinking

Hazardous Reactions: Reacts to produce toxic gases with acid or heat
Incompatible Materials: Acids, reducing chemicals, combustible materials, metals, ammonium salts
Hazardous Decomposition: Emits corrosive vapors of chlorine, hydrochloric acid, sulfur oxides upon thermal decomposition
Acute Toxicity: Harmful by oral (LD50 rat ~2600 mg/kg), low toxicity by dermal route, toxic by inhalation of dust
Skin Corrosion/Irritation: Causes skin irritation and redness on contact
Eye Damage/Irritation: Causes strong pain, lesions, prolonged watering, redness
Respiratory Sensitization: Coughing, throat irritation, difficulty breathing in sensitive individuals
Carcinogenicity: Not classified as carcinogenic by IARC, NTP or OSHA
Other Data: No known reproductive, mutagenic or chronic toxicity concerns in scientific literature at standard exposures
Ecotoxicity: Toxic to aquatic life, severe short-term effects on fish, invertebrates and algae, do not allow product or rinse water to enter drains
Persistence and Degradability: Undergoes abiotic degradation in water, stable in storage for long periods without light or heat exposure
Bioaccumulation: Not likely to persist or bioaccumulate in food chain at standard concentrations
Mobility in Soil: Dissolves easily, moves through soil with water, greater risk in sandy or coarse substrates
Other Adverse Effects: Promotes eutrophication if released in quantity, avoid spills close to lakes, rivers and public waterways
Disposal Methods: Dispose unused product and contaminated containers via licensed chemical waste contractor, dilute large spills and neutralize slowly with sodium sulfite or thiosulfate before discharge (subject to regulations)
Sewage Disposal: Never flush in sewage or septic tanks, do not mix with household garbage
Contaminated Packaging: Decontaminate containers by triple rinsing, puncture to prevent re-use, send for professional disposal
Additional Guidance: Consult local, regional and national hazardous waste disposal regulations for full compliance
