Hazard categories

WHO Class III -Slightly hazardous Main Hazard: A relatively low toxicity herbicide. Poisonous if swallowed. Irritating to eyes and respiratory system. Flammability: Water based product, non-flammable. Chemical Hazard (Simazine): Possible risks of irreversible effects. Most mammals tend to be insensitive to simazine. For unknown reasons, sheep and cattle are especially susceptible to poisoning by simazine. Doses of 500 mg/kg were fatal in sheep with death delayed for 5 – 16 days. Symptoms exhibited by poisoned sheep include lower food intake, higher water intake, incoordination, tremors, and weakness, especially in the hindquarters. Sheep show liver damage. Chemical Hazard (Terbuthylazine): Harmful if swallowed. Biological Hazard: Highly toxic to algae. 4. FIRST AID MEASURES AND PRECAUTIONS If poisoning is suspected, do not wait for symptoms to develop. Contact a physician, the nearest hospital, or the nearest Poison Control Centre. Symptoms of Human Poisoning: The triazine herbicides (simazine and terbuthylazine) disturb energy metabolism (thiamin and riboflavin functions). Toxicity symptoms include difficulty in walking, tremors, convulsions, paralysis, cyanosis, slowed respiration, miosis (pin point pupils), gut pain, diarrhea and impaired adrenal function. Some triazines are mildly irritating to skin, und upper respiratory tract. Systemic toxicity is unlikely unless very large amounts have been ingested. Symptoms of simazine poisoning include incoordination, tremor and weakness, cyanosis and clonic convulsions. The acute toxicity to Terbuthylazine for man in thought to be low, and no adverse health effects from exposure to this herbicide have been reported.
