Personal Precautions: Use personal protective equipment, avoid generating dust, ventilate area, avoid eye or skin contact
Environmental Precautions: Prevent large amounts from entering drains, ditches, or waterways, notify authorities if release poses environmental risk
Containment Methods: Sweep up spills without raising dust, transfer to labeled containers for proper disposal
Clean-Up Methods: Wash spill area with water after removing bulk material, dispose rinse water in accordance with regulations
Handling: Handle with care to avoid release of dust, keep containers tightly closed, good industrial hygiene is important
Storage: Store in cool, dry, well-ventilated area, keep away from incompatible materials such as strong acids and strong oxidizers, avoid moisture
Specific Uses: Only use for designated industrial or laboratory applications, do not mix with acids unless instructed by process requirements
Incompatible Materials: Acids, strong oxidizing agents, reducing agents
Safe Packaging: Use containers resistant to corrosion, clearly labeled, tightly sealed
Exposure Limits: No occupational exposure limits established, use time-weighted average standards for nuisance dust where available
Engineering Controls: Use local exhaust ventilation, maintain good general ventilation
Personal Protective Equipment: Safety goggles, chemical-resistant gloves (nitrile or neoprene), lab coat or apron, dust mask or respirator in dusty conditions
Hygiene Measures: Wash hands before eating or drinking, remove contaminated clothing, avoid touching face during use
Monitoring: Regularly check workplaces for airborne dust and surface residue, ensure PPE is in good condition
Appearance: White crystalline powder

Other Properties: Stable under normal conditions, produces corrosive vapors on decomposition
Reactivity: Stable for storage and use under recommended conditions
Chemical Stability: Shows little change when kept dry and away from incompatible substances
Hazardous Reactions: Reacts with acids to release toxic sulfur dioxide or similar gases
Incompatible Materials: Strong acids, oxidizing agents
Decomposition Products: Nitrogen oxides, sulfur oxides, ammonia, sodium compounds may form in fire or when mixed with acids
Condition to Avoid: Contact with moisture, excessive heat, open flames, contamination with acids
Routes of Exposure: Inhalation, ingestion, skin contact, eye contact
Acute Toxicity: Low oral and dermal toxicity in animal studies
Chronic Toxicity: No evidence of long-term toxicity from repeat exposure at ordinary handling levels
Skin Irritation: Causes mild to moderate irritation, prolonged use with bare skin worsens effects
Eye Irritation: Severe irritation possible on direct contact, may damage mucous membranes
Inhalation Risks: Dust may cause coughing, sore throat, nasal irritation
Ingestion Effects: Nausea, abdominal pain, vomiting if substantial amounts swallowed
Carcinogenicity: Not listed as carcinogenic by IARC, NTP, OSHA
Other Effects: Does not bioaccumulate, not mutagenic in standard tests
Ecotoxicity: May harm aquatic organisms at high concentrations, generally low toxicity due to rapid dilution
Persistence and Degradability: Readily dissociates in water, undergoes slow hydrolysis
Bioaccumulative Potential: Does not bioaccumulate in food chains
Mobility in Soil: High mobility in waterlogged soil due to solubility
Other Environmental Hazards: Massive release could alter local water chemistry, leading to temporary impacts on invertebrates and algae
Disposal Methods: Dispose as non-hazardous chemical waste in accordance with local regulations, chemical incineration or landfill accepted in many regions
Packaging Disposal: Rinse and recycle or dispose of containers as chemical waste
Do Not: Flush large amounts to drains or sewers
Additional Advice: Small residues can go to wastewater with plenty of dilution if allowed by authorities, document disposal for compliance
