| Hazard Information | Back Directory | 【General Description】
A colorless oily liquid with a garlic-like odor. Denser than water and slightly soluble in water. Flash point 40°F. Vapors heavier than air. May irritate skin and eyes. Used to make other chemicals. | 【Reactivity Profile】
DIMETHYL DISULFIDE(624-92-0) is a reducing agent. A dangerous fire hazard when exposed to oxidizing materials. Emits toxic fumes of oxides of sulfur when heated to decomposition or on contact with acids [Sax, 9th ed., 1996, p. 1320]. | 【Air & Water Reactions】
Highly flammable. Slightly soluble in water. | 【Health Hazard】
May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution. | 【Fire Hazard】
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. |
