Allgemeine Beschreibung
Colorless liquid with a weak odor .
Air & Water Reaktionen
Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick, 1979 p.151-154, 164]. Miscible with water.
Reaktivität anzeigen
Dipropylene glycol monomethyl ether may react violently with strong oxidizing agents. May generate flammable and/or toxic gases with alkali metals, nitrides, and other strong reducing agents. May initiate the polymerization of isocyanates and epoxides.
Health Hazard
CALL FOR MEDICAL AID. LIQUID: Irritating to skin and eyes. Harmful if swallowed. Remove contaminated clothing and shoes. Flush affected areas with plenty of water. IF IN EYES, hold eyelids open and flush with plenty of water. May be harmful by inhalation, ingestion, or skin absorption. May cause irritation.
Brandgefahr
Combustible. Emits toxic fumes under fire conditions.
Flammability and Explosibility
Non flammable
Sicherheitsprofil
fddly toxic by ingestion and skin contact. An experimental skin and human eye irritant. A dd allergen. Combustible when exposed to heat or flame; can react with oxidizing materials. To fight fire, use dry chemical, CO2, mist, foam. When heated to decomposition it emits acrid smoke and irritating fumes. See also GLYCOL ETHERS.
mögliche Exposition
PrimaryIrritant. This material is used in antifreeze formulations,cosmetics, cleaning compounds, and heat transfer fluids; asa solvent for nitrocellulose and other synthetic resins.
Erste Hilfe
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin,remove contaminated clothing and wash immediately withsoap and water. Seek medical attention immediately. If thischemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart actionhas stopped. Transfer promptly to a medical facility. Whenthis chemical has been swallowed, get medical attention.Give large quantities of water and induce vomiting. Do notmake an unconscious person vomit.
Lager
: Color Code—Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Store in tightly closed containers in a cool, well-ventilatedarea away from strong oxidizers (such as chlorine, bromine,and fluorine). Before entering confined space where thischemical may be present, check to make sure that an explosive concentration does not exist. Store in tightly closedcontainers in a cool, well-ventilated area away from heatand incompatible materials. Sources of ignition, such assmoking and open flames, are prohibited where this chemical is used, handled, or stored in a manner that could createa potential fire or explosion hazard. Metal containersinvolving the transfer of 5 gallons or more of this chemicalshould be grounded and bonded. Drums must be equippedwith self-closing valves, pressure vacuum bungs, and flamearresters. Use only nonsparking tools and equipment, especially when opening and closing containers of thischemical.
Inkompatibilitäten
Strong oxidizers. The substance can presumably form explosive peroxides in contact with air.Reacts violently with strong oxidants.
