The trial is aimed at continuous, high-transient off-highway plant, starting with waste shredding, not homes, generators or everyday tractors.

A duty holder would normally work through DSEAR, find where a flammable atmosphere could form, zone those areas and control ignition sources, with oversight in this area from the Health and Safety Executive.
