Name: Magnesium Peroxide
Chemical Formula: MgO2
Common Forms: Powder, white or off-white
Typical Uses: Soil remediation, wastewater treatment, deodorizing, bleaching agent
Main Hazards: Strong oxidizer, may intensify fire, can cause respiratory irritation, skin and eye discomfort
Hazard Statements: Exposure can create reactive oxygen species, amplify combustion, lead to inhalation hazards especially in unventilated areas
Signal Word: Warning – avoid contact with flammable materials, dust clouds, and moisture
Chemical Component: Magnesium Peroxide
Concentration: Generally above 80% for technical grade
Common Impurities: Magnesium oxide, magnesium hydroxide, trace heavy metals
Inhalation: Remove to fresh air immediately, monitor for coughing or throat irritation, seek medical help if symptoms persist
Skin Contact: Rinse thoroughly with water, remove contaminated clothes, use mild soap, medical attention necessary if redness stays
Eye Contact: Rinse carefully with clean water for several minutes, avoid rubbing, lift eyelids to flush thoroughly
Ingestion: Do not induce vomiting, rinse mouth, provide water to drink if alert, get prompt medical assistance
Hazard Under Fire: May release oxygen under heat, feeding combustion of nearby flammable substances
Suitable Extinguishing Media: Water mist, dry powder, avoid direct water spray on dust piles
Protective Equipment: Full protective clothing, self-contained breathing apparatus, keep distance to reduce risk of exposure to gases
Personal Protection: Wear dust mask, nitrile gloves, chemical splash goggles, avoid touching face
Containment: Isolate spill, use non-sparking tools, avoid creating dust clouds, collect with dry material such as sand
Cleanup: Sweep gently, secure in sealed container, ventilate area well after removal
Handling Precautions: Avoid open flames and heat, prevent contact with water or acids in storage area, open containers slowly and carefully
Storage: Store in cool, dry place protected from sunlight, keep containers tightly sealed, segregate from flammable or reducing agents, minimize stacking to reduce pressure on containers
Workplace Controls: Use proper ventilation, work with local exhaust to limit inhalation risks, implement spill protection protocols
Personal Protective Equipment: Use gloves resistant to oxidative damage, impervious apron, safety glasses or face shield, wear dust respirators if dust levels exceed limits
Hygiene: Wash hands after handling, avoid eating or drinking in work area, keep contaminated clothing separated for decontamination
Appearance: White or off-white powder
Odor: Faint, sometimes slightly chlorine-like
pH (slurry): Slightly basic
Boiling Point: Decomposes before boiling
Melting Point: Not distinct, decomposes
Solubility: Slight in water, reacts to release oxygen
Decomposition: Releases oxygen gas and magnesium oxide
Chemical Stability: Unstable near heat, moisture, or acids, decomposes when contaminated
Hazardous Reactions: Strong oxidizer, can cause exothermic reaction if mixed with organic materials or reducing agents
Conditions to Avoid: Heat, open flames, friction, damp conditions, long-term storage in poor containers
Incompatible Materials: Acids, organic materials, aluminum, finely divided metals
Short-term Effects: Can irritate lungs if dust is inhaled, may cause sneezing or coughing, skin can become red or irritated if exposed for extended periods
Long-term Exposure: Prolonged inhalation may potentially damage lung tissue, repeated skin contact could lead to dermatitis
Not listed as carcinogenic by IARC or NTP
Routes of Entry: Inhalation, skin, eyes, ingestion
Symptoms: Cough, shortness of breath, redness, tearing of eyes, dry skin
Toxicity to Aquatic Life: Oxygen-rich byproducts can disrupt aquatic environments, may lead to temporary increases in dissolved oxygen, shifting organism balances
Persistence: Breaks down in nature, products include magnesium oxide and oxygen
Bioaccumulation: Unlikely due to breakdown, not known to build up in food chains
Soil Effects: Used to oxygenate soils, high concentrations can alter local chemistry, impacting microbes
Preferred Disposal: Follow local hazardous waste regulations, do not pour into drains or rivers, solid residues go in specified chemical waste bins
Cleanup: Neutralize any remaining product before disposal if possible, use professional services for bulk quantities
Classification: Classified as an oxidizer by many transport authorities, falls under hazardous materials
Packaging: Requires robust, sealed, airtight containers, labeling must reflect oxidizer status
Precautions: Avoid extreme temperatures, pack away from fuels and organic cargo
Spill Procedure: Secure area, notify authorities if transport spill occurs
Labelling: Subject to chemical hazard labeling in many jurisdictions, including oxidizer pictogram, warning statements
Regulated Activities: Purchase, storage, handling all regulated under chemical safety rules, some places require reporting threshold quantities to authorities
Workplace Limits: Review local exposure limits, and comply with reporting and training needs for workers
