Chemical Name: Potassium Metaperiodate
Chemical Formula: KIO4
Physical Appearance: White crystalline powder
Main Use: Oxidizing agent in laboratory and industrial applications
Odor: Odorless
Solubility: Moderately soluble in water
Common Synonyms: Periodic acid, potassium salt
Main Hazards: Potent oxidizer, increases fire risk in contact with combustible materials
Health Risks: Irritation to eyes, skin, and respiratory tract; ingestion can lead to significant health effects
Environmental Concerns: Harmful to aquatic life; causes long-lasting effects in water systems
Hazard Symbols: Oxidizing, harmful, environmentally hazardous
Signal Word: Danger
Ingredient: Potassium Metaperiodate
Purity: Typically over 98%
Other Components: Trace impurities possible, usually not intended nor specified
Inhalation: Move to fresh air right away; seek medical attention if coughing or shortness of breath develops
Skin Contact: Rinse skin thoroughly with water; remove contaminated clothing; obtain medical help if discomfort persists
Eye Contact: Flush eyes with plenty of water for several minutes; avoid rubbing; seek medical evaluation
Ingestion: Do not induce vomiting; rinse mouth with water; get professional medical help
Known Fire Hazards: This agent feeds oxygen to flames; heat or mixing with combustible materials turns even a minor fire risk into a serious situation
Extinguishing Methods: Use water spray, fog, or foam; avoid using dry chemicals that can react with oxidizers
Protective Measures: Wear full protective gear, including breathing apparatus; limit exposure; concentrate on isolating materials
Special Hazards: Decomposes upon heating to release irritating and toxic fumes, including iodine compounds
Personal Precautions: Keep away from combustible materials; ventilate the area; use personal protective gear
Spill Clean-Up: Gather up spilled material using non-combustible tools; place waste in sealed containers; avoid dusty conditions
Environmental Measures: Prevent discharge into water systems and sewers
Handling Guidelines: Handle only in well-ventilated places; avoid generating dust; keep away from open flames and easily oxidizable substances
Storage Practices: Store in tightly closed containers, in cool, dry, well-ventilated areas; never store with acids or organic materials
Incompatibilities: Avoid contact with reducing agents, flammable or combustible materials, metals, acids
Workplace Controls: Rely on strong local exhaust ventilation systems to lower dust buildup; keep eyewash stations and showers nearby
Personal Protective Gear: Use chemical-resistant gloves, goggles or face shields, laboratory coats; wear suitable respirators if dust may be inhaled
Hygiene Practices: Wash hands before eating, drinking, or using restrooms; launder contaminated clothes before reuse
Appearance: White crystalline powder, solid at room temperature
Melting Point: Decomposes before melting
Solubility in Water: Moderate
Odor: None
Vapor Pressure: Negligible at room temperature
Density: Value near 3.5 g/cm³
Oxidizing Power: Strong, especially with easily oxidizable materials
Chemical Stability: Stable in dry, cool, and well-ventilated storage
Reactive Conditions: Sensitive to heat, moisture, contamination with organic or readily oxidizable substances
Hazardous Reactions: Risk of ignition or explosion if contaminated
Decomposition Products: Heat or reaction with incompatible materials produces iodine oxides and potassium compounds
Acute Effects: Can irritate eyes, skin, and lungs; accidental ingestion potentially causes gastrointestinal upset and other systemic effects
Chronic Effects: Repeated exposure over time may affect thyroid function due to iodine component
Sensitization: Skin and respiratory tract may become sensitized with frequent or prolonged exposure
Carcinogenicity: Not classified as carcinogenic by major regulatory bodies
Environmental Impact: Toxic to aquatic organisms, with risk of bioaccumulation
Persistence: Stable; remains in natural environments and water courses
Mobility: Highly soluble in water; can travel beyond the site of release
Best Practices: Follow local, regional, and national hazardous waste disposal rules
Container Disposal: Decontaminate before reuse or disposal; never dispose in ordinary garbage or landfill
Avoid: Release into the environment, drains, or waterways
Shipping Regulations: Classified as dangerous goods
Key Risks in Transit: Fire risk heightened by vibration, heat, and contact with incompatible materials
Storage During Transit: Use labeled, tightly sealed containers; segregate from combustibles and reducing agents
Labeling Rules: Clear hazard communication required
Governing Standards: Subject to local, national, and international controls for transport, use, and disposal
Worker Safeguards: Compliance with workplace chemical safety legislation remains essential
