Molecular Weight: 158.03 g/mol
Impurities: Trace levels of manganese dioxide, potassium chloride, water content may vary in impure samples
SDS Number: Vendor-specific, ensure most recent version from manufacturer
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, remove contact lenses, seek medical help
Skin Contact: Remove contaminated clothing, rinse skin under running water, mild soap recommended, seek medical advice for irritation
Ingestion: Do not induce vomiting, rinse mouth, give water to drink if conscious, medical attention recommended
Inhalation: Move person to fresh air, provide oxygen if needed, consult physician
Symptoms: Burning sensation, redness, coughing, stomach upset, respiratory issues, possible tissue damage with prolonged exposure
Suitable Extinguishing Media: Use water spray, flooding amounts of water; avoid dry chemicals, foam, or CO2 as heat may decompose product
Specific Hazards: Strong oxidizer, may intensify fire with combustibles, reacts with organic material, decomposes with heat releasing oxygen and toxic fumes
Protective Equipment: Firefighters wear self-contained breathing apparatus and full protective clothing
Special Procedures: Remove containers from fire area if safe, cool containers exposed to flames, avoid inhaling fumes, keep upwind, avoid runoff into waterways
Personal Precautions: Avoid contact with skin and eyes, wear gloves, goggles, dust mask or respirator
Environmental Precautions: Prevent spill from entering drains, watercourses, or soil
Cleanup Methods: Use non-combustible absorbent material like sand or vermiculite, sweep up and place in suitable containers for disposal, wash area with plenty of water
Disposal: Collect in labeled containers for hazardous waste disposal per local regulations, decontaminate surfaces, minimize dust generation
Handling: Work in well-ventilated area, avoid dust formation, use spark-proof tools, keep away from heat, sparks, flame, and all sources of ignition, wash hands before breaks
Storage Conditions: Store in cool, dry, well-ventilated area, keep containers tightly closed, segregate from acids, reducing agents, organic materials, and combustibles
Incompatible Materials: Glycerin, sugars, alcohols, concentrated acids, strong reducing agents, finely divided metals and other oxidizable substances
Container Materials: Use glass, certain approved plastics, corrosion-resistant metals; avoid aluminum, steel, wood or paper for bulk storage
Occupational Exposure Limit: TLV (Threshold Limit Value): 0.2 mg/m3 (as Mn), ACGIH guideline
Engineering Controls: Local exhaust ventilation, containment, closed systems for large scale
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), safety goggles or face shield, lab coat or coveralls, approved respirator for dust or fumes
Hygiene Measures: Do not eat, drink or smoke in work area, wash hands and face after handling, remove contaminated clothes and launder before reuse

Chemical Stability: Stable under normal temperature and dry storage, decomposes in presence of moisture, heat, or incompatible materials
Conditions to Avoid: Exposure to heat, direct sunlight, contact with organic materials or reducing agents
Incompatible Substances: Combustible and organic materials, acids, peroxides, sulfur compounds
Decomposition Products: Releases oxygen, forms potassium manganate and manganese dioxide, possible manganese fumes
Acute Toxicity: Harmful if swallowed, can cause stomach pain, nausea, vomiting, diarrhea, kidney damage
Skin and Eye Irritation: Causes burns, dark stains, possible ulceration, severe redness, blurred vision
Respiratory Effects: Inhalation of dust may lead to coughing, irritation of airways, chest pain
Delayed or Chronic Effects: Chronic exposure can lead to nervous system disorders, reproductive toxicity, manganism (parkinsonian symptoms)
LD50 (Oral, Rat): ~1090 mg/kg
Carcinogenicity: Not classified as carcinogen by IARC, NTP, or OSHA
Sensitization: Not a known sensitizer
Aquatic Toxicity: Highly toxic to aquatic life, dangerous for fish and invertebrates at low concentrations (LC50 for fish: 0.75 mg/L/96 hr)
Persistence and Degradability: Breaks down in environment but oxidizes organic matter, disrupts aquatic systems
Bioaccumulation: Manganese may bioaccumulate, potassium permanganate does not persist in pure form
Other Adverse Effects: Alters water chemistry, potential to cause long term adverse effects for aquatic habitats
Waste Treatment: Treat with reducing agents such as sodium thiosulfate or hydrogen peroxide to neutralize before disposal
Regulatory Disposal: Hand over to licensed hazardous chemical disposal contractor
Empty Containers: Decontaminate before recycling or disposal
Avoid: Disposing of in normal trash, drains, or surface waters, label clearly as hazardous waste
