Measurements for the assessment of ignition risks from static electricity

Practical work is described to test two approaches devised for avoiding risks of ignition during mechanical mixing, in flammable atmospheres, of materials which easily become highly charged. The approaches are: first, changes to the sequence of production operations to segregate periods of high static charge generation from the time when flammable atmospheres are present; second, use of additives to modify the charge decay rates of critical materials.<
