Inhalation: Move individual to fresh air, support breathing with oxygen if necessary, seek medical advice if symptoms such as coughing or difficulty in breathing persist
Skin Contact: Immediately remove contaminated clothing, wash skin thoroughly with soap and water, seek medical attention if irritation develops or persists
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, seek medical advice in case of discomfort
Ingestion: Do not induce vomiting, rinse mouth with water, obtain medical attention right away, never give anything by mouth to an unconscious person
Symptoms to Watch For: Drowsiness, headache, dizziness, respiratory distress, gastrointestinal discomfort, skin or eye redness
Suitable Extinguishing Media: Use dry chemical, carbon dioxide, foam, or sand; water can spread material or create splatter
Fire Hazards: Combustion produces hazardous vapors, including oxides of manganese, carbon oxides, and irritating organic gases
Protective Equipment: Firefighters require full protective gear and self-contained breathing apparatus
Special Precautions: Fire water runoff may be toxic, contain and prevent from entering drains or watercourses, cool containers with water spray
Personal Precautions: Evacuate unprotected personnel, ventilate area, eliminate sources of ignition
Environmental Precautions: Avoid discharge into soil, waterways, or drains, use diking to contain spillage
Cleanup Methods: Absorb spill with inert absorbent like earth, sand or vermiculite, place material in suitable containers for disposal, clean contaminated area with detergent and water
Protective Equipment: Wear chemical-resistant gloves, boots, goggles, and respiratory protection in case of significant vapor formation
Handling: Handle in well-ventilated areas, avoid creating aerosols or dust, do not breathe fumes, avoid skin or eye contact, keep away from open flames, spark sources, or static discharge
Storage: Store in tightly sealed containers, kept cool and dry, away from heat, acids, alkalis and incompatible materials, ensure proper labeling, keep out of reach of children
Transfer Precautions: Ground all equipment during transfer to avoid static buildup, use explosion-proof electrical/ventilating/lighting equipment where required
Exposure Limits: Manganese OSHA PEL: 5 mg/m3 ceiling; ACGIH TLV: 0.02 mg/m3 TWA (respirable fraction)
Engineering Controls: Use local exhaust ventilation or process enclosures to minimize exposure
Personal Protective Equipment: Nitrile or neoprene gloves, chemical-resistant apron, safety goggles or full-face shield, approved respirator for particulates and organic vapors if required
Hygiene Measures: Wash hands before breaks and after work, remove contaminated clothing before entering eating or rest areas

Flash Point: Typically above 65°C
Vapor Pressure: Low at ambient temperature
Solubility: Insoluble in water; soluble in organic solvents
Density: Approximately 0.9-1.1 g/cm3
Viscosity: High, depending on concentration/solvent
Chemical Stability: Stable at standard temperature and pressure
Conditions to Avoid: Exposure to excessive heat, open flame, sparks, strong acids or alkali
Incompatible Materials: Strong oxidizing agents, strong acids or bases, reactive metals
Hazardous Decomposition: Oxides of carbon, oxides of manganese, irritating organic compounds
Polymerization: Does not occur under normal conditions
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Poisons Symptoms: Respiratory tract irritation, dizziness, nausea, vomiting, abdominal pain, skin and eye redness, headache, central nervous system effects
Acute Toxicity: Oral LD50 in rats estimated around 1000-2000 mg/kg (variable per mixture)
Chronic Effects: Prolonged or repeated exposure can lead to manganese poisoning, affecting neurological and mental function; skin contact may lead to dermatitis
Carcinogenicity: Not identified as a confirmed carcinogen by IARC, NTP, or OSHA, but other ingredients or impurities may present risk
Sensitization: May cause allergic skin response in sensitive individuals
Ecotoxicity: Very toxic to aquatic organisms, may cause long-term adverse effects in the environment
Mobility: Limited water solubility increases persistence at spill site
Persistence and Degradability: Slowly degrades in environment; bioaccumulation in aquatic organisms possible
Bioaccumulation: Manganese can accumulate in food chain, chronic exposure hazardous to aquatic systems
Other Hazards: Spillage poses particular risk to fish and aquatic invertebrates, avoid contamination of waterways and soils
Waste Treatment Methods: Dispose through licensed hazardous waste facility in accordance with local, regional, and national regulations; do not pour down drain
Container Disposal: Triple rinse containers, puncture and dispose as hazardous waste
Precautions: Incinerate only in approved facility, avoid generation of dusty residues
Environmental Warning: Prevent material from entering surface waters, groundwater or soil
