Safety Technical Indices
In the context of this purely informal overview a set of safety-relevant characteristics are to be introduced which should be known for the characterisation of inflammable solids and dusts in respect of the safety-relevant interpretation of plants.
It pertains to this:
The glow temperature describes the minimum ignition temperature of a dust layer with a one-sided thermal load.
A dust is dust explosionable, if its mixture with air can be initiated by effect of an ignition source of defined energy to a keeping flame propagation. This is connected with a pressure increase in the closed container.
The Dust Explosion Limits describe the concentration range of types of dusts with air, within an explosion is possible.
