5 - Fire Fighting Measures

---

EXTINGUISHING MEDIA
Suitable: For small (incipient) fires, use media such as
"alcohol" foam, dry chemical, or carbon dioxide. For large
ALDRICHwww.molbase.com
fires, apply water from as far as possible. Use very large
quantities (flooding) of water applied as a mist or spray; solid
streams of water may be ineffective. Cool all affected
containers with flooding quantities of water.
SPECIAL RISKS
Specific Hazard(s): Emits toxic fumes under fire conditions.
Vapor may travel considerable distance to source of ignition and
flash back. Flammable liquid.
Explosion Hazards: Vapor may travel considerable distance to
source of ignition and flash back. Container explosion may occur
under fire conditions.
SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS
Wear self-contained breathing apparatus and protective clothing
to prevent contact with skin and eyes.
SPECIFIC METHOD(S) OF FIRE FIGHTING
Keep down vapors with water spray.
