Molecular Formula: C8H18MgO2
Other Components: Trace solvent from synthesis, possible minor hydrolysis products under poor storage conditions
Inhalation: Remove person to fresh air, seek medical attention for coughing or respiratory distress, provide oxygen if available
Skin Contact: Remove contaminated clothing, rinse skin immediately with copious amounts of water, do not apply neutralizing chemicals, seek immediate medical help for burns
Eye Contact: Rinse eyes immediately with running water for at least 15 minutes, lift eyelids occasionally, seek urgent ophthalmologist attention
Ingestion: Rinse mouth with water only if conscious, do not induce vomiting, seek immediate medical help, provide physician with product details
Notes for Physician: Treat effect of caustic burns, monitor for systemic toxicity and possible delayed pulmonary effects
Suitable Extinguishing Media: Use class D dry powder agents designed for metal fires, do not use water, carbon dioxide or halogenated extinguishing agents
Hazards During Fire: May produce irritating or toxic fumes including magnesium oxide, possible risk of violent reaction if water contacts product during fire
Protective Equipment: Full fire-resistant protective clothing and self-contained breathing apparatus
Special Procedures: Isolate fire area, allow fire to burn if safe to do so, apply extinguishing agent cautiously to avoid dust cloud and violence
Explosion Sensitivity: Fines or dust may be sensitive to ignition, product may reignite after extinguishing
Personal Precautions: Ventilate area, keep unprotected personnel away, avoid contact with skin, eyes, and breathing dust
Environmental Precautions: Avoid dispersal into waterways or sewers, use barriers to prevent runoff
Cleanup Methods: Scoop spilled solid using non-sparking, dry tools into suitable container under inert atmosphere if possible, avoid creating or inhaling dust
Decontamination: Residue neutralized with dry sand or suitable absorbent for metal alkoxides, collect and dispose as hazardous waste
Reporting: Report significant releases to environmental authorities as required under local regulations
Safe Handling: Handle only in dry, well-ventilated areas, use spark-proof tools, ground all transfer processes, avoid dust generation, keep container closed when not in use
Storage Conditions: Store in original tightly-sealed containers, keep away from moisture, acids, oxidizers and all ignition sources, suitable storage is cool, dry, and well-ventilated, open containers in inert atmosphere if possible
Special Precautions: Clearly label containers, inspect regularly for leaks, maintain inventory controls, restrict access to qualified personnel only
Incompatible Materials: Strong acids, water, oxidizing agents, halogenated hydrocarbons
Transfer Measures: Use dry, inert gas (e.g., nitrogen) during handling and transfer for bulk quantities
Occupational Exposure Limits: No established occupational exposure limit for the compound, use in well-controlled laboratory or handling area
Engineering Controls: Handle in fume hood or local exhaust system, use explosion-proof equipment
Personal Protective Equipment: Wear chemical-resistant gloves such as nitrile, full eye protection (goggles or face shield), flame-resistant lab coat, closed footwear
Respiratory Protection: Wear suitable dust and vapor respirator if engineering controls do not maintain airborne levels below recommended limits
Hygiene Measures: Wash hands thoroughly after handling, do not eat, drink or smoke in work area, remove contaminated clothing and launder before reuse
Appearance: White to off-white powder or crystalline solid, may yellow faintly with age or exposure

Other Properties: Sensitive to moisture, reacts exothermically
Chemical Stability: Stable in unopened, dry containers, decomposes with moisture or acids
Conditions To Avoid: Heat, sparks, static discharge, contact with water, humid environments
Incompatible Materials: Acids, oxidizers, halogenated hydrocarbons, protic solvents
Hazardous Decomposition Products: Magnesium oxide, tert-butyl alcohol, possible flammable gases
Polymerization: Not known to occur
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Toxicity: Can cause chemical burns of skin, eyes, respiratory tract, possible systemic effects if absorbed
Symptoms: Burning pain, redness, possible delayed blistering on skin contact, severe irritation or destruction of eye tissue, pulmonary symptoms if inhaled, abdominal pain and gastrointestinal symptoms if ingested
Chronic Effects: Repeated exposure can desensitize skin or respiratory tract, no long-term studies showing carcinogenicity or reproductive toxicity
Other Health Hazards: Persons with preexisting skin, eye or respiratory disorders could fare worse after exposure
Aquatic Toxicity: Product hydrolyzes to magnesium hydroxide and tert-butyl alcohol, magnesium ion can affect freshwater and marine species at high concentrations
Persistence and Degradability: Organic portion degrades slowly in natural environments, magnesium ions persist in soil and water
Bioaccumulative Potential: Low for magnesium and organic fragment
Mobility in Soil: Magnesium disperses easily in water, tert-butyl residues may volatilize or biodegrade
Other Adverse Effects: Product increases local alkalinity and may damage aquatic microorganisms and plants
Waste Treatment Methods: Collect and neutralize residues with non-combustible, inert absorbent under dry conditions, slowly quench with isopropanol and then water under supervision
Disposal of Product: Dispose through licensed hazardous waste contractor, do not landfill untreated solids
Contaminated Packaging: Clean with dry inert material before recycling, handle as hazardous waste if contamination is suspected
Regulations: Dispose in accordance with state, local, and federal requirements, never discharge to environment
