Protective Equipment for Firefighters: Chemical-resistant full protective gear, positive pressure self-contained breathing apparatus
Special Firefighting Procedures: Move containers from fire area if possible, use water spray to cool unopened drums, prevent run-off from entering water sources
Personal Precautions: Use proper protective equipment, avoid contact with skin, eyes, and clothing, ventilate area
Spill Response: Absorb spillage with non-combustible absorbent materials like sand, soil, or vermiculite, gather waste for disposal
Environmental Precautions: Prevent further leakage or spillage if safe to do so, do not let product enter drains or surface water
Clean-up Methods: Place absorbed material in appropriate waste container for disposal in compliance with local regulations, clean contaminated surface with detergent
Handling: Wear chemical-resistant gloves and goggles, avoid inhalation of vapors or mists, use only in areas with adequate ventilation, keep away from food and beverages
Storage: Store in tightly closed containers in a cool, dry, well-ventilated place, protect from moisture, heat, and direct sunlight, segregate from incompatible materials (strong oxidizers, acids)
Incompatible Materials: Acids, strong bases, strong oxidizers
Safe Storage Terms: Keep container tightly sealed when not in use, label storage area clearly for hazardous chemicals
Engineering Controls: Local exhaust ventilation, safety showers, eyewash stations
Occupational Exposure Limits: No specific limits established, control exposure as low as reasonably achievable
Personal Protective Equipment: Chemical-resistant gloves (nitrile recommended), impervious protective clothing, safety goggles, face shield for splash protection, P2 or P3 type respirator for dust or vapor exposure
Hygiene Measures: Wash hands and face before breaks and at end of workday, avoid eating, drinking, or smoking in work areas, launder contaminated clothing regularly
Environmental Exposure Controls: Use procedures to prevent release to environment, collect and dispose of waste properly

Acute Toxicity: Oral LD50 (rat) approximately 400-1500 mg/kg
Inhalation: May cause respiratory irritation, coughing, or shortness of breath
Skin Contact: Causes irritation, prolonged or repeated contact may cause dermatitis
Eye Contact: Causes moderate to severe irritation
Chronic Effects: No established evidence for carcinogenicity or mutagenicity, long-term exposure data limited
Sensitization: Not classified as a sensitizer based on available studies
Ecotoxicity: Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment
Persistence and Degradability: Biodegradability is limited; once released into water, can persist in sediments
Bioaccumulative Potential: Log Kow approximately 9.5, indicating high potential for bioaccumulation
Mobility in Soil: Strongly adsorbed to soil particles, unlikely to leach to groundwater
Other Adverse Effects: Care needed to prevent releases to environment
Waste Treatment Methods: Dispose of contents in accordance with local, regional, national, and international regulations, incineration preferred method
Contaminated Packaging: Rinse drums and containers thoroughly, send for recycling or disposal at licensed facility
