FIRE AND EXPLOSION HAZARD DATA

 Flash Point: N/A Test Method Used: --- Flammable Limits: N/A LEL:--- UEL: ---
 Tungsten Particles, High Density Alloy and Hard Cemented Carbide Product are not fire hazards. Dusts generated in grinding  operations may ignite if allowed to accumulate and subjected to an ultra-high temperature ignition source.

 Extinguishing Media:
 For powder, smother with dry sand, dry dolomite, ABC type fire extinguisher, or flood with water.

 Special Fire Fighting Procedures:
 For a powder fire confined to a small area, use a respirator approved for toxic dusts and fumes. For a large fire, fire fighters  should use self-contained breathing apparatus.

 Unusual Fire and Explosion Hazards:
 During production process, dusts may present a fire or explosion hazard under rare favoring conditions of particle size,  dispersion and ultra-high temperature ignition source. However, this is not expected to be a problem under normal packaging  and dust-proof handling conditions.
