SECTION 2: Hazards identification

PHYSICAL PROPERTIES Appearance: White liquid, emulsion Odor: Odorless EMERGENCY OVERVIEW: Caution. Hazards to humans and domestic animals. Harmful if swallowed. HAZARDOUS DECOMPOSITION PRODUCTS: Thermal decomposition may release toxic and/or hazardous gases. SYMPTOMS OF ACUTE EXPOSURE: Inhalation: Diuron: Overexposure by inhalation may cause liver enlargement, spleen, and thyroid effects, red blood cell destruction, reduction of the blood’s oxygen carrying capacity with cyanosis, weakness, or shortness of breath by formation of methemoglobin. Ethylene Glycol: The low vapor pressure of this component minimizes the risk of excessive exposure to the vapors at room temperature. Exposure to vapor and mists is possible at elevated temperatures and adverse effects have been reported from exposure to mists. Inhalation of high concentrations of this component can cause irritation to the respiratory tract. Eye Irritation: May cause irritation. Skin Absorption: Diuron: Slightly toxic on absorption through skin. Temporary skin swelling and redness may occur on contact. Significant skin permeation after contact appears unlikely. Ethylene Glycol: May be absorbed through the skin, which may cause damage to kidneys and depression of central nervous system. Ingestion: Slightly toxic. Based on animal data, ingestion of ½ pound or more of Diuron (1 pint of formulation) could be fatal to a person. SYMPTOMS OF CHRONIC EXPOSURE: Diuron: Long-term exposure to low levels of Diuron is not known to cause any ill effects in humans. Ethylene Glycol: Prolonged or repeated exposure to this component’s vapors may cause damage to kidneys, liver, lungs, blood, or the central nervous system.
