Properties of combustible dusts (safety characteristics).
Handbook of Explosion Prevention and Protection. Weinheim, Germany: Wiley-VCH, 2004 Jan; :379-417
The properties of combustible dusts that are decisive for explosion protection are described by safety characteristics (SCs) such as limiting values of important properties of substances beyond which certain hazards (fires, explosions, formation of hazardous substances) can occur when handling these substances or mixtures. They are determined in the laboratory according to defined test methods in special measurement setups with the objective of obtaining comparable decision criteria for situations that can occur in practice - a goal that cannot always be reached in a simple manner and to a satisfactory degree. Only in very rare cases are SCs genuine properties of substances. They are always related to particular cases of practical application and, in a very broad sense, serve to define operational conditions that permit safe handling of hazardous substances. With the aid of SCs one can classify substances of interest according to specific properties or one can compare them with respect to the risk they pose in a given situation.
