Hose applications are also needed to pack the finished products: they help extrude and blister foils, suck away packaging waste and add small parts to the packages.

Since May 2009, explosion protection measures in Germany have been governed by TRBS 2153 – which also applies to the transport of plastic pellets, for example, if large amounts of dust are produced as a result of the conveying process or the plastic is transported in powder form. Compliance with TRBS 2153 is nearly always stipulated if the plastic is delivered in silo vehicles, because its sheer volume is assumed to inevitably lead to high dust levels.

General statements contained in TRBS 2153 (formerly BGR 132)

A new section describing the pneumatic transport of combustible bulk materials has been incorporated. This section refers to the situation where a potentially explosive atmosphere exists inside the hose. In such cases, the hose wall should be made of material that is either conductive or capable of electrostatic discharge.

TRBS 2153 is not a directive but a technical rule. It is a legislative text.

TRBS 2153 is an ownership based rule, in other words responsibility for ensuring compliance with this technical rule lies primarily with the owner.
