Health Effects: Studies with laboratory animals have shown this product to be slighty toxic. Ingestion of large doses of bifenthrin by laboratory animals produced signs of toxicity which included clonic convulsions, tremours, and bloody nasal discharge. This formulation also contains aromatic hydrocarbons. Inhalation of aromatic hydrocarbon vapours may cause central nervous system depression, dizziness, disturbance in vision, and respiratory irritation. Moderately irritating to the eyes. Contact with skin may be irritating. Dermal sensitisation may occur.

Swallowed: The product is slightly toxic; the oral LD50 in the rat is 531 mg/kg.
Eye: Moderately irritating to the washed eye and severely irritating to the unwashed eye.
Skin: Minimally irritating. Dermal sensitisation may occur. Practically non-toxic; the dermal LD50 in the rabbit is >2000 mg/kg.
Inhaled: Slightly toxic. Four hour inhalation toxicity LC50 in rats has been measured at 4.9 mg/L. Inhalation of aromatic hydrocarbon vaopurs may cause central nervous system depression, dizziness, disturbances in vision and irritation.

Chronic: In studies with laboratory animals, bifenthrin, the active ingredient in Biflex, did not cause reproductive toxicity or teratogenicity. Tremours were associated with repeated exposure of dogs, rats, rabbits, and mice to bifenthrin. The overall results from a battery of genotoxicity studies indicate that bifenthrin is not considered to be genotoxic. Ames test results were negative. Kidney and liver damage is possible from overexposure to aromatic hydrocarbons over long periods. Additionally, some reversible haematopoietic depression has been observed in animals with extended exposure to aromatic hydrocarbons.


Swallowed: If poisoning occurs, contact a doctor or Poisons Information Centre. If swallowed, and if more than 15 minutes from a hospital, induce vomiting, preferably using Ipecac Syrup (APF). Do not induce vomiting or give anything by mouth to an unconscious person.
Eye: Wash eyes with water for 15 minutes. If irritation occurs and persists, obtain medical attention.
Skin: If on skin or clothing, remove contaminated clothing at once, and wash skin with plenty of soap and water. See a doctor if irritation persists.
Inhaled: Remove patient to fresh air. If breathing discomfort occurs, obtain medical attention
First Aid Facilities: A supply of Ipecac Syrup (APF) should be kept on hand.

Advice to Doctor

Antidote: Bifenthrin the active ingredient in this product is a pyrethroid insecticide. The fomulation also contains petroleum distillatea that can cause severe pneumonitis or fatal pulmonary edema if aspirated. Consideration should be given to gastric lavage with an endotracheal tube in place. Treatment is otherwise symptomatic and supportive.


Exposure Standards: None applicable

Engineering Controls: Thoroughly ventilate all transport vehicles prior to unloading. General air replacement or dilution ventilation is sufficient for material handling and storage, but local exhaust ventilation should be used when filling or emptying this product.

Personal Protection: For normal handling wear long sleeve uniform or overalls and head covering. For larger exposures, as in the case of spills, wear full body cover barrier suit, such as rubber rain suit. Where potential for splash, spray or mist exists, wear chemical protective goggles or a full face shield. Emergency eye wash facilities would be located nearby. For vapour or mist exposure wear a half face air purifying respirator which is approved for pesticides. Respirator selection is based on an airborne concentration. Wear chemical protective gloves made of rubber or neoprene or PVC gauntlet-style gloves when handling this product. Inspect regularly for leaks.

Flammability: Not flammable (Flashpoint 68°C)


Storage and Transport: Biflex is not classified as a dangerous goods under the Australian Code. Store in a cool, dry, well ventilated location. Avoid excess heat. No smoking eating or drinking should be allowed where material is used or stored. Keep out of reach of children and animals. Store in original containers only. Do not locate near or contaminate food or feed by storage or disposal. Wash all exposed skin surfaces prior to smoking drinking or eating. All workers should shower at the end of each work day after handling this product. Wash all clothing after each use.

Spills and Disposal: In the case of spillage contain and absorb spilled material with absorbent material such as sand clay or cat litter and dispose of waste as indicated below or according to the Australian Standard 2507 - Storage and Handling of Pesticides. Wear prescribed protective clothing and equipment. Keep out animals and unprotected persons. Keep material out of streams and sewers. Vacuum, shovel or pump waste into an approved drum. To decontaminate spill area, tools and equipment, was with a suitable solution (ie organic solvent, detergent, bleach or caustic) and add the solution to the drums of wastes already collected. Label for contents. Dispose of drummed wastes, including decontamination solution, in accordance with the requirements of Local or State Waste Management Authorities. Do not cut or weld metal containers. Vapours that form inside may create an explosion hazard.

Fire/Explosion Hazard:
Flashpoint: 68°C
Degree of fire/explosion hazard: Slightly combustible Non explosive. Avoid excess heat and fire. Thermal decomposition and burning may produce toxic by-products.
Extinguishing media: Soft steam water fog. If necessary, foam, CO2, or dry chemical
Hazardous decomposition products: Carbon monoxide, carbon dioxide, hydrogen chloride, chlorine, fluorine and hydrogen fluoride
Special fire-fighting procedures: Isolate fire area. Evacuate dowwind residents. Wear full protective clothing and self contained breathing apparatus. Do not breathe smoke or vapours generated. Try to keep containers cool with soft steam water fog.

OTHER INFORMATION: The product is toxic to fish. Do not contaminate waterways, ponds and dams.
