SECTION III PHYSICAL DATA
Boiling Point: None Vapor Pressure (Mm Hg): 0.038-0.050
Specific Gravity (H2O = 1): 0.64 To 1.35 Vapor Density (Air = 1): N/A
Percent Volatile By Volume: N/A Evaporation Rate: N/A
Explosion Point: 2370F
Solubility In Water: Salts are soluble in water, but the nitric esters (NG and EGDN) are only slightly soluble.
Appearance And Odor: The explosive is a mixture of absorbents, white oxidizing salts, and a non-organic flame suppressant. Tan
color with white granules. Slightly sweet odor. One and one half pounds of a MSHA approved explosive is surrounded by a flame
suppressing water gel composed of a freezing point depressant, water, yellow dye and thickeners.
SECTION IV FIRE AND EXPLOSION DATA
Flash Point: Not Available
Flammable Limits: Not Available
Extinguishing Media: See below
Special Fire Fighting Procedures: Do not fight fires. Withdraw personnel immediately. Allow fire to burn itself
out.
