Ingestion: Rinse mouth, drink water, do not induce vomiting, seek medical attention if feeling unwell or if large amount is swallowed
Notes for Physician: Symptomatic treatment, monitor for signs of sensitization or allergic reaction
Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide to extinguish
Unsuitable Media: Avoid direct water jet as it may spread burning liquid
Specific Hazards: Can release acrid smoke, carbon monoxide, and carbon dioxide upon thermal decomposition
Protective Equipment: Firefighters should wear self-contained breathing apparatus and protective gear
Advice for Firefighters: Keep containers cool using water spray, prevent runoff into drains or water sources
Personal Precautions: Wear gloves and eye protection; avoid contact with skin or eyes
Environmental Precautions: Prevent product from entering soil, sewers, surface, or groundwater
Containment: Absorb spill with earth, inert material, or vermiculite; shovel into appropriate waste containers
Clean-Up Method: Wash spill area thoroughly after collection; ventilate enclosed spaces if necessary
Disposal: Dispose of as chemical waste under local regulations
Safe Handling: Use in well-ventilated area, avoid inhalation and direct skin contact, handle with care
Storage Conditions: Store tightly sealed in a cool, dry, well-ventilated place, keep container away from sources of ignition
Incompatibilities: Strong oxidizers, strong acids and bases may trigger hazardous reactions
Hygiene: Wash hands after handling, do not eat, drink, or smoke during use
Other Precautions: Keep out of reach of children, use only as directed
Exposure Limits: No established occupational exposure limits
Engineering Controls: Use local exhaust for laboratory handling, ensure adequate air exchange in storage or prep rooms
Respiratory Protection: Not typically required; use respirator if aerosol or mist formation likely

Polymerization: Not known to occur
Acute Toxicity: Low toxicity by oral and dermal routes, not expected to be acutely toxic in standard animal studies
Routes of Exposure: Contact with skin and eyes, accidental ingestion
Symptoms: Redness or irritation of affected skin, temporary eye irritation, headache if handled in bulk with limited ventilation
Chronic Effects: No evidence of long-term or cumulative toxicity in repeated-use scenarios; nutritional studies indicate safety as food additive at usual levels
Sensitization: Not fully characterized; skin allergies unlikely but possible with repeat exposure
Mutagenicity: Studies have not shown genetic damage
Carcinogenicity: Not classified as carcinogen by IARC, NTP, OSHA
Ecotoxicity: Readily biodegradable, no evidence of bioaccumulation, low aquatic toxicity expected based on chemical structure
Behavior in Environment: Tends to absorb into soil and degrade by natural microbial action
Mobility: Low mobility in soil due to high partition coefficient
Persistence and Degradability: Not persistent, breaks down rapidly in presence of air, light, and microorganisms
Potential for Bioaccumulation: Minimal
