FIRE FIGHTING MEASURES Flammable Properties

Flash Point : Will not burn Autodecomposition : 632 C (1170 F)

Other burning materials may cause "FREON" 22 to burn weakly.

Chlorodifluoromethane is not flammable at ambient temperatures and atmospheric pressure. However, chlorodifluoromethane has been shown in tests to be combustible at pressures as low as 60 psig at ambient temperature when mixed with air at concentrations of 65 volume ft air. Experimental data have also been reported which indicate combustibility of "FREON" 22 in the presence of certain concentrations of chlorine.

Fire and Explosion Hazards:

Cylinders may rupture under fire conditions. Decomposition may occur.

Extinguishing Media

As appropriate for combustibles in area. Extinguishant for other burning material in area sufficient to stop burning.

Fire Fighting instructions

Use water spray or fog to cool containers. Self-contained breathing apparatus (SC3A) is required if cylinders rupture or contents are released under fire conditions. Water runoff should be contained and neutralized prior to release.
