DANGER
Explosion hazard from hybrid mixtures
Hybrid mixtures are mixtures of flammable dusts with explosive gas/air atmospheres which
can together create a dangerous explosive atmosphere if they occur at the same time.
Changes can arise in the safety characteristics here, such as a change in the zonal
classification, increase in the explosion pressure, reduction in the minimum ignition energy
and a reduction in the maximum temperatures to be observed.
An explosion can result. This can result in death, serious injury or material damage.
● For this reason, the relative characteristics must be considered both for gas (zones 0, 1
and 2) and for dust (zones 20, 21 and 22) where hybrid mixtures arise. It is necessary for
a competent assessor to determine in the individual case whether the parameters
determining ignition are unfavorably affected in a particular hybrid mixture.
● Motors with dual plates for G ("Gas") andD ("Dust") may only be used where these two
simultaneously occur after the user has first analyzed the properties of the hybrid mixture.
