Measurements for the assessment of ignition risks from staticelectricity

摘要

Practical work is described to test two approaches devised foravoiding risks of ignition during mechanical mixing, in flammableatmospheres, of materials which easily become highly charged. Theapproaches are: first, changes to the sequence of production operationsto segregate periods of high static charge generation from the time whenflammable atmospheres are present; second, use of additives to modifythe charge decay rates of critical materials
