CLASSES OF FIRES: ABCD
CLASS D -
FLAMMABLE SOLIDS AND WATER REACTIVE SUBST'S
combustible metals such as magnesium or titanium - dry chemical fire extinguisher
- A device designed primarily for class B and C fires containing dry chemical agents that extinguish fire by a chemical chain reaction. Three types of chemicals are used: sodium bicarbonate, potassium bicarbonate, and ammonium phosphate.

-
FUEL TEMP'S
FLASH POINT - THE MIN TEMP AT WHICH A FLAMMABLE LIQUID RELEASES SUFFICIENT VAPOR TO FORM AN IGNITABLE MIXTURE WITH AIR NEW THE SURFACE OF THE LIQUIE W/ IN A CONTAINER
-
FUEL TEMP'S
FIRE POINT -
(USUALLY 15 TO 20 DEGREES ABOVE FLASH PT)
-MIN TEMP AT WHICH A FLAMMABLE LIQUIED RELEASES SUFFIENT VAPOR TO FORM AN IGNITABLE MIXTURE WITH AIR NEAR THE SURFACE OF THE LIQUID THAT WILL INGNITE AND CONTINUE CONTINUE TO BURN - AUTOIGNITION POINT
-
The minimum temperature at which a substance will continue to burn without additional application of external heat. (WEB)

I(IGNITABLE)
C (CORROSIVE)
R (REACTIVE)
E (TOXICITY IS CHAR OF THE WASTE)
H (ACUTE HAZZ)
T (TOXIC- MORE THAN E) -
