Inhalation: Remove exposed person to fresh air, keep at rest, monitor for respiratory distress, seek medical advice if symptoms persist.
Skin Contact: Remove contaminated clothing immediately, wash affected area thoroughly with soap and water, call a physician if irritation develops.
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present, continue rinsing, consult an ophthalmologist if irritation continues.
Ingestion: Rinse mouth with water, never give anything by mouth if victim is unconscious, do not induce vomiting, get medical attention immediately.
Most Important Symptoms/Effects: Headache, dizziness, nausea, difficulty breathing, skin and eye irritation, allergic skin reactions in sensitized individuals.
Immediate Medical Attention: Emergency services should treat by airway protection and symptomatic management for severe exposure.
Suitable Extinguishing Media: Use water spray, foam, dry chemical or carbon dioxide.
Unsuitable Extinguishing Media: Do not use high pressure water jet due to risk of spreading contamination.
Specific Hazards: May give off toxic fumes of hydrogen chloride, hydrogen fluoride, nitrogen oxides, sulfur oxides when burned, risk of inhalation of decomposition byproducts.
Protective Equipment and Precautions: Firefighters need full protective clothing and self-contained breathing apparatus, cool containers exposed to fire with water spray, keep run-off out of waterways.
Personal Precautions: Evacuate area, avoid breathing dust or vapors, ventilate area, wear suitable protective equipment.
Environmental Precautions: Prevent product from entering drains, soil, and waterways due to high aquatic toxicity.
Methods for Containment: Avoid generation of dust, cover with suitable inert absorbent material, sweep up and shovel into suitable labelled containers.
Cleaning Procedures: Wash area with detergent and water, package waste for standard hazardous waste disposal, decontaminate tools and equipment with safe solvents.
Safe Handling: Avoid skin and eye contact, do not eat, drink, or smoke during use, use only in well-ventilated areas, clean up spills quickly.
Technical Measures: Implement mechanical extraction and localized ventilation where possible.
Safe Storage Conditions: Store in original tightly closed container, keep out of direct sunlight, store in cool, dry, well-ventilated location.
Incompatibilities: Keep away from oxidizing agents, acids, alkalis, and moisture, ensure storage away from feed and foodstuffs to prevent contamination.
Packaging Materials: High density polyethylene, fiber drums with inner lining.
Exposure Limits: Occupational exposure limits not established for Fipronil, good industrial hygiene practices recommended.
Engineering Controls: Use local exhaust ventilation, mechanical handling for larger operations, keep concentration in air below possible exposure level.
Personal Protective Equipment: Respiratory protection with organic vapor/particulate filter, nitrile or neoprene gloves, chemical splash goggles, coveralls or apron, closed-toe shoes.
Hygiene Measures: Wash hands, forearms, and face thoroughly after handling, remove and wash contaminated clothing before reuse, do not take contaminated clothing home.
Environmental Controls: Avoid release into agricultural run-off or municipal drains, implement environmental monitoring where discharges are possible.
