Impurities: Trace process contaminants (none classified as hazardous above reporting thresholds per OSHA)
Inhalation: Remove to fresh air, seek medical attention if symptoms occur
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present, seek medical advice if irritation persists
Skin Contact: Wash with soap and water, remove contaminated clothing and wash before reuse, seek medical care for persistent irritation
Ingestion: Rinse mouth, do not induce vomiting, call poison control or a doctor for guidance
Most Important Symptoms: Burning sensation, redness, coughing, nausea, headache
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide, water spray (avoid high pressure water streams that may spread material)
Unsuitable Media: Direct water jet may spread fire
Specific Hazards: May release toxic fumes, including hydrogen chloride, hydrogen fluoride, carbon monoxide, and oxides of nitrogen
Protective Equipment: Wear self-contained breathing apparatus and full protective gear
Special Procedures: Prevent runoff into water bodies and drains, cool adjacent containers with water spray
Personal Precautions: Avoid breathing vapor/dust, ensure adequate ventilation, use personal protective equipment (gloves, goggles, respirator for high concentrations)
Environmental Precautions: Avoid discharge to surface waters, sewers, soil; notify authorities if there’s a risk to waterways
Cleanup Methods: Absorb spill with earth, sand, or other inert material, collect in suitable container for disposal, clean contaminated surfaces with detergent and water, ventilate area
Prevention of Secondary Hazards: Remove all ignition sources from area
Safe Handling: Use only outdoors or in well-ventilated areas, avoid contact with skin, eyes, and clothing, do not eat, drink or smoke during handling, keep away from heat and ignition sources
Storage Conditions: Store tightly closed in original container in cool, dry, well-ventilated location, away from food and feed, keep out of reach of children
Incompatibilities: Store away from strong oxidizers, acids, bases
Specific Requirements: Comply with local, state, and federal regulations for pesticide storage
Exposure Limits: No OSHA PEL or ACGIH TLV established for Bifenthrin itself
Engineering Controls: Local exhaust or general room ventilation to maintain airborne concentrations below recommended exposure levels
Personal Protective Equipment: Chemical-resistant gloves, long-sleeved coveralls, safety goggles or face shield, respiratory protection if handling in poorly ventilated area or for large spills

Persistence and Degradability: Moderately persistent in soil (soil half-life 7–125 days, varies with conditions); strongly adsorbed to soil particles
Bioaccumulation Potential: Possible; log Kow 6.2 indicates high potential for bioaccumulation
Mobility in Soil: Low mobility due to strong soil binding
Other Effects: Avoid contamination of surface water, as Bifenthrin poses serious risks to aquatic ecosystems
Waste Disposal Methods: Dispose of Bifenthrin-containing wastes according to federal, state, and local regulations; never pour unused product down drain
Container Disposal: Triple rinse (or equivalent) empty container, add rinsate to tank mix, then recycle or offer for puncture and disposal at approved landfill
