Suitable Extinguishing Media: Use water spray, carbon dioxide, dry chemical powder, alcohol-resistant foam
Specific Hazards: Emits toxic fumes under fire conditions including carbon monoxide, carbon dioxide, and phenolic compounds
Protective Equipment: Firefighters need self-contained breathing apparatus and full protective gear
Other Advice: Avoid runoff from fire control entering drains, watch for re-ignition in laboratory fires
Personal Precautions: Wear gloves, goggles, lab coat, ensure adequate ventilation
Environmental Precautions: Prevent entry of spilled product into waterways, do not wash down drains, contain spillage with suitable absorbent material
Cleanup Methods: Sweep up and place in approved waste containers, wash contaminated area with water and detergent, ventilate spill zone, dispose as chemical waste
Handling: Avoid breathing dust, avoid contact with eyes and skin, use only in well-ventilated areas, handle under chemical hood if possible, follow standard laboratory safety practices
Storage: Store in tightly closed container, keep in cool, dry, well-ventilated place away from incompatible substances such as strong oxidizers and acids, label containers clearly, store away from food and beverages
Engineering Controls: Use chemical fume hood, safety showers, eyewash stations
Exposure Limits: No established OSHA, NIOSH, or ACGIH exposure limits for this compound
Personal Protective Equipment: Gloves (nitrile or neoprene), safety glasses or goggles, lab coat, respirator if dust is generated and ventilation is inadequate
General Hygiene Measures: Wash hands thoroughly after handling, remove contaminated clothing before leaving work area, no eating or drinking in use areas

Decomposition Products: Releases carbon oxides, methoxybenzene derivatives on strong heating or in fire
Conditions to Avoid: High humidity, high temperatures, strong oxidizers, strong acids
Acute Toxicity: Data limited for this specific compound, structurally similar tartaric acids reported to have moderate oral toxicity, may cause gastrointestinal irritation
Skin Irritation: May cause redness or irritation on prolonged or repeated contact
Eye Irritation: Causes significant irritation, avoid exposure
Chronic Effects: Long-term effects not fully studied; avoid repeated exposure unless more toxicological info is available
Sensitization: No reports indicating sensitization reactions
Other Potential Effects: Based on related compounds, ingestion in large amounts may cause systemic acidosis and related symptoms
Ecotoxicity: Not enough data for this compound, related tartaric acids known to have low acute toxicity to aquatic organisms
Persistence and Degradability: Expected to be biodegradable based on chemical structure
Bioaccumulation: Low potential for bioaccumulation, predicted for similar compounds
Mobility: Low mobility in soil, weak water solubility may limit movement in environment
Other Adverse Effects: No evidence of chronic effects on aquatic life, prudent practice to prevent release into waterways
