Component: Hydrogen Peroxide
Concentration: Varies by grade, commonly 3–50% in solutions
Impurities: Water, possible trace metal stabilizers
Ingredients contributing to hazard: Active hydrogen peroxide component, high reactivity due to instability of O-O bond
Inhalation: Move affected person to fresh air immediately, keep breathing freely, seek medical attention for persistent symptoms
Skin Contact: Remove contaminated clothing, rinse skin thoroughly with cool water for at least 15 minutes, medical attention if irritation persists
Eye Contact: Rinse eyes cautiously with water for several minutes, remove contact lenses, wash for at least 15 minutes, urgent medical attention required
Ingestion: Rinse mouth with water, do not induce vomiting, seek immediate medical help, provide details of concentration ingested
Emergency Treatment Notes: Severe burns call for prompt medical evaluation, respiratory problems may require oxygen
Suitable Extinguishing Media: Water spray, fog, do not use dry chemicals or carbon dioxide
Fire Hazards: Decomposes to release oxygen, intensifies fire, reacts violently with combustibles
Protective Equipment for Firefighters: Full protective suit, self-contained breathing apparatus to avoid inhaling vapors and oxygen-rich fumes
Specific Hazards Arising from Chemical: Oxygen release can escalate combustion of surrounding materials, risk of explosion if confined
Firefighting Instructions: Cool containers with flooding amounts of water, isolate hazard area, avoid run-off into sewers and waterways
Personal Precautions: Evacuate non-essential personnel, ventilate area, use personal protective equipment including gloves, goggles, face shield
Spill Containment: Absorb with inert material such as sand or vermiculite, avoid organic materials, prevent entry into drains
Cleanup Procedures: Collect absorbed material in clean, non-combustible container, wash spill area thoroughly with water, dispose of in accordance with regulations
Environmental Precautions: Keep out of water bodies, report large releases as required by local legislation
Decontamination: Diluate residue with water, prevent contact with combustible substances during cleanup
Handling: Wear chemical-resistant gloves and eye protection, use in well-ventilated space, avoid contact with incompatible substances such as organic materials, metals, reducing agents
Storage Conditions: Store in original vented containers, away from direct sunlight and heat, maintain temperature below room temperature to prevent decomposition
Incompatibles: Strong acids, alkalis, metals including copper and iron, combustible materials, organic solvents
Special Storage Notes: Keep away from storage areas for food, drink, and animal feed, do not store in unlabeled or non-compatible containers
Transfer Precautions: Use corrosion-resistant equipment, avoid splashing and static discharge
Exposure Limits: OSHA PEL: 1 ppm (1.4 mg/m3), ACGIH TLV: 1 ppm (1.4 mg/m3) for hydrogen peroxide vapor
Engineering Controls: Local exhaust ventilation or fume hoods as needed to control vapor concentrations, maintain low levels in workplace air
Personal Protective Equipment: Chemical splash goggles, face shield, gloves made of suitable material (nitrile or neoprene), protective clothing to avoid skin contact
Respiratory Protection: Use approved air-purifying respirator in areas where vapor concentration exceeds recommended limits
Hygiene Measures: Wash hands after handling, avoid eating or drinking in handling area

Decomposition Products: Water and oxygen
Flash Point: Nonflammable
Viscosity: Slightly higher than water
Chemical Stability: Unstable on exposure to heat, light, metallic contaminants, decomposes over time
Reactivity: Strong oxidizer, vigorous reaction with many organic and inorganic substances
Hazardous Decomposition Products: Water and oxygen gas, risk of overpressure from rapid gas evolution in confined spaces
Conditions to Avoid: Direct sunlight, high temperatures, contamination by metals or organic substances
Polymerization: Will not polymerize, prone to rapid decomposition
Incompatible Materials: Metals (iron, copper, chromium), reducing agents, combustibles, flammable liquids and solids
Acute Toxicity: Oral LD50 (rat) 1193 mg/kg (35% solution), inhalation can cause severe respiratory tract irritation
Chronic Effects: Repeated or prolonged contact may cause skin irritation and burns, long-term inhalation may produce chronic bronchitis
Potential Routes of Exposure: Skin, eyes, inhalation, ingestion
Symptoms: Local tissue burns, redness and blistering of skin, vision damage or loss if splashed in eyes, chest pain or cough if inhaled
Carcinogenicity: Not classified as carcinogenic according to IARC, NTP, OSHA
Mutagenicity: Some evidence of mutagenic effects in laboratory tests
Reproductive Toxicity: Not expected to be a reproductive toxin at occupational exposure levels
Sensitization: Not classed as a skin or respiratory sensitizer
Ecotoxicity: Harmful to aquatic organisms in concentrated form, high reactivity with organic matter in water
Persistence and Degradability: Rapidly breaks down to water and oxygen, not persistent in environment
Bioaccumulation: Unlikely due to rapid decomposition
Mobility in Soil: Highly mobile in aqueous phase, minimal risk of long-term soil contamination
Other Adverse Effects: Large spills can cause local changes in oxygen content, risk to aquatic organisms
