Molecular Weight: 95.21 g/mol
Inhalation: Move exposed person to fresh air and monitor breathing. If discomfort continues, seek medical attention.
Skin Contact: Wash skin with plenty of soap and water. Remove contaminated clothing and footwear. Seek medical attention if irritation persists.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing and seek medical attention if symptoms continue.
Ingestion: Rinse mouth with water. Do not induce vomiting. Contact a physician or poison control center if the person feels unwell.
Most Important Symptoms: Redness and irritation in eyes and skin, respiratory discomfort with dust exposure
Suitable Extinguishing Media: Use water spray, dry powder, foam, or carbon dioxide as appropriate for adjacent materials.
Unsuitable Extinguishing Media: None known
Specific Hazards: Nonflammable, but reacts vigorously and exothermically with water, generating heat and possibly splattering.
Hazardous Combustion Products: Emits hydrogen chloride fumes and magnesium oxide at high temperatures.
Protective Equipment for Firefighters: Full protective clothing, including self-contained breathing apparatus. Cool containers exposed to fire with water spray.
Personal Precautions: Evacuate unnecessary personnel. Wear approved dust mask, gloves, eye protection, and protective clothing.
Environmental Precautions: Prevent large spills from entering drains, sewers, or waterways. Dike area if necessary to keep material contained.
Methods for Cleaning Up: Sweep or shovel up material into containers for disposal. Minimize generation of dust. Wash spill area thoroughly with water after removal. Maintain adequate ventilation.
Handling: Use in well-ventilated areas. Minimize dust formation and avoid breathing dust. Wear suitable protective equipment. Wash thoroughly after handling. Do not eat, drink, or smoke during use.
Storage: Keep container tightly closed in a cool, dry, and well-ventilated area. Store away from moisture, acids, base metals, and incompatible materials.
Incompatibilities: Avoid contact with water, strong acids, and strong bases which may cause undesirable chemical reactions or corrosion of storage containers.
Occupational Exposure Limits: Not established for magnesium chloride; control dust exposure according to local guidelines (typically as nuisance dust, 5-10 mg/m³ for inhalable particles).
Engineering Controls: Ventilation systems and local exhaust recommended to limit dust concentration.
Personal Protection: Eye protection (safety glasses or goggles), chemical resistant gloves, dust mask or respirator (P2/ N95 minimum if dust is generated), long-sleeved clothing
Hygiene Measures: Routine washing of hands and face after handling. Change contaminated clothing and launder before reuse.

Conditions to Avoid: Moisture (can absorb water and form solution), extreme heat
Incompatible Materials: Water, strong acids, strong bases, alkali metals
Hazardous Decomposition Products: On strong heating, may produce hydrogen chloride gas, magnesium oxide.
Dangerous Reactions: Exothermic reaction with water, may generate splattering; reacts with metal oxides or hydroxides.
Acute Toxicity: LD50 (oral, rat) estimated at 2800 mg/kg; magnesium chloride considered of low toxicity.
Skin Corrosion/Irritation: May cause mild irritation with prolonged or repeated contact.
Serious Eye Damage/Eye Irritation: Causes eye irritation and discomfort.
Respiratory Sensitization: Not known to be a sensitizer.
Germ Cell Mutagenicity: No mutagenic effects reported.
Carcinogenicity: Not classified as a carcinogen by IARC, NTP, or OSHA.
Reproductive Toxicity: No data indicating reproductive toxicity in humans.
Repeat Dose Toxicity: Prolonged or repeated exposure may result in dehydration or electrolyte imbalance if ingested in large amounts.
Eco-Toxicity: Large amounts in water may cause harm to aquatic plants and animals by altering natural pH and ion balance.
Persistence and Degradability: Inorganic compound; dissociates and dilutes in water; non-biodegradable.
Bioaccumulation Potential: Not bioaccumulative; magnesium and chloride ions readily disperse in the environment.
Mobility in Soil: Highly soluble, moves rapidly in wet soil.
Other Adverse Effects: In some regions, runoff from de-icing or industrial use raises local water hardness and salinity.
Waste Disposal Methods: Dispose of in accordance with local, regional, or national regulations. Can often be landfilled or washed into sewers with plenty of water where permitted.
Contaminated Packaging: Rinse thoroughly before disposal or recycling. Avoid direct disposal in water bodies.
Waste Codes: Not regulated as hazardous waste; regulations may vary by location
