Ingestion: Rinse mouth, drink water to dilute, seek medical advice if large amounts consumed or discomfort follows
Seek Immediate Help: For persistent difficulty in breathing, severe eye involvement, or unusual negative effects
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, or foam according to local practice
Specific Hazards: Product is not particularly flammable, small dust clouds could combust in intense heat but rarely occurs in food settings
Protective Equipment: Use protective gear and sealed breathing apparatus in fire conditions
Combustion Products: Burning can produce carbon oxides, nitrogen oxides, sodium oxides
Advice for Firefighters: Stay upwind and avoid inhaling vapors, cool containers with water
Personal Precautions: Wear mask and gloves to prevent dust inhalation and skin exposure
Environmental Precautions: Prevent spillage from entering water systems in large quantities
Clean-Up Procedures: Sweep or vacuum up spill gently to avoid raising dust, transfer to suitable waste container, residue can be washed up with water
Disposal: Comply with local waste disposal requirements, minimize dust generation during clean-up
Safe Handling: Avoid raising large quantities of dust, ensure clean, dry working surfaces, limit eating, drinking, or smoking in work areas
Conditions for Safe Storage: Store tightly sealed in original packaging, keep in cool, dry room free from direct sunlight or high humidity

Carcinogenicity: Not identified as carcinogen by IARC, NTP, or OSHA
Reproductive Toxicity: No evidence suggesting harm at typical exposure levels
Mutagenicity: Animal and cell studies have not shown genetic damage
Ecotoxicity: MSG breaks down rapidly in the environment, so high volumes can lead to nutrient loading and algae growth if discharged in quantity
Persistence and Degradability: Readily biodegradable by soil and water microbes
Bioaccumulation: Not significantly bioaccumulative
Mobility in Soil: Dissolves in water and moves with groundwater easily
Other Adverse Effects: Large spills into water systems raise local sodium and nitrogen levels, which could disrupt sensitive aquatic ecosystems in rare cases
