Nonconductive materials:

Nonconductive materials, like as rubber, fabric, or passing through plastic sheeting, or over rolls will also create charges of static electricity.  Static from these materials, as well as static from the belts, could be discharged along with grounded metal combs or tinsel collectors. A Radioactive substances and static neutralizers using electrical discharges are also employed for this reason.

Grounding and Bonding systems should be checked frequently for electrical continuity.  Preferably before every fill, the exposed category of the bonding and ground system should be inspected for elements which have deteriorated since of corrosion or which have or else been damaged. Several organizations specify which bonds and grounds are constructed of bare-braided flexible wire since it facilitates inspection and avoids broken wires from being concealed.

Electricity becomes a source of ignition whereas flammable vapors exist if the proper categories of electrical equipment for these atmospheres either has not been installed or has not been managed.
