Dust cloud explosibility data

Maximum explosion pressure, Pmax and explosibility rate constant, Kst, is used to design explosion protection systems including explosion venting, explosion isolation and explosion suppression systems.

Minimum explosible concentration

MEC, may be used as an element of a deflagration risk assessment that takes into account all of the factors that are pertinent to an assessment of the explosion and fire hazard of a particular process.

Limiting oxygen concentration

LOC Dusts, can be of value when developing fire and explosion prevention and protection strategies that employ inert gases to reduce the concentration of oxygen in a process space.

Minimum ignition energy

MIE, of a dust-cloud is primarily used to assess the likelihood of ignition during processing and handling. The likelihood of ignition is used to evaluate the need for precautions such as explosion prevention systems.

Ignition temperature of a dust cloud

MIT Cloud, procedure measures the minimum temperature at which a given dust cloud will auto-ignite when exposed to air heated in a furnace at local atmospheric pressure.

Hot surface ignition temperature of a dust layer

MIT Layer, measures the minimum temperature at which a dust layer will self-heat. This dust ignition characteristic can be used as one element of a fire risk assessment that takes into account all pertinent risk factors.

Ignition by self heating

Is a procedure to assess the tendency of a bulk dust to undergo spontaneous ignition when exposed to a heated environment.
