ombustion Hazard Testing 
           of Dusts, Liquids and Gases

The Combustion Research Center (CRC) has served the
process safety community for over 40 years by providing
high quality combustion hazard data on dusts, liquids
and gases.  We employ recognized test methods, such
as those published by ASTM, U.S. DOT, UN, and others,
to conduct dust explosion testing and tests to determine
the ignition properties of dusts, liquids, and gases. 
Combustion hazards include a wide variety of situations
where the basic elements of a fire or explosion come
together. Elements of combustion hazards include,
but are not limited to:

 The presence of a process material raises
  questions such as:
Is a process dust combustible?
  -Is a dust sufficiently combustible to be rated Class II?
  -Are flammable
vapors present?

• The presence of air (or other oxidizing medium)
  -Is a process inerting system working correctly?
the oxygen concentration being maintained 
   low enough?

• An actual or potential source of ignition
  such as...
  -Hot surfaces
  -Electrical components 
  -Static charge accumulation

 Mixing of a fuel vapor in air may form a
  flammable or combustible mixture if the
  mixture composition is in the flammable

 Where an airborne flammable mixture occurs
  there is the risk of an explosion. Such cases
  -Vapor-air mixtures at fuel concentrations in the 
   flammable range–above the LFL and below the UFL.
  -Dust-air mixtures where the airb
orne dust
   concentration exceeds the MEC.

• Explosion protection measures are needed
  when flammable atmospheres are possible
  in process systems.

  -Dust (or vapor) explosibility properties are needed 
   to design explosion vent and explosion suppression 



Understanding combustion hazards and implementing safety measures starts with reliable data on process materials.

Material combustion hazard testing is the focus of the CRC.

Our goal is to provide accurate, conservative safety data in a prompt professional manner.
