DUST HAZARD AND EXPLOSION PREVENTION SAFETY
Figure 1-26
In a confined area, certain concentrations of dust in an
otherwise normal atmosphere can explode when spark
occurs. This phenomenon is known as a dust explosion.
It has been known to occur in grain elevators,
underground mines, flour mills, crushers, etc. The dust
itself need not be an explosive or flammable substance.
The safe operation of transferring potentially explosive
dust should be addressed by the following:
• Static charge dissipation
• Spark prevention
See “Static Charge Dissipation” on page 1-28 and
“SPARK AND FIRE PREVENTION SAFETY” on
page 1-29 for specific information on addressing these
two concerns.
