Article 4.4.7.2.6.

1.

The diffusion of dust during transport, loading and unloading of dust-producing substances shall be avoided as much as possible by:

1

adequately moistening wettable substances in dust category SC2;

2

providing operators with procedures for the use of the transport and transshipment equipment that at least contains the relevant elements stated in Appendix 4.4.7.2.

Appendix 4.4.7.2. may be supplemented or amended by the minister.

2.

The diffusion of dust during transport, loading and unloading of dust-producing substances using claw buckets shall be avoided as much as possible by:

1

using a claw bucket whereby the blades fit together well;

2

using a claw bucket that is half-closed or closed at the top for substances in dust categories SC1 and SC2, if the substance being handled allows this.

3.

The diffusion of dust during transport, loading and unloading of dust-producing substances using conveyor belts shall be avoided as much as possible by:

1

shielding open conveyor belts outside against wind using longitudinal screens, transverse screens or shelters if dust emissions remain visible after the code of good practice stated in Appendix 4.4.7.2 has been applied;

2

switching to a closed conveyor system if dust emissions remain visible after taking the measures stated in point 1.

A fixed conveyor belt for the transport of substances in dust category SC1 that is commissioned after 31 December 2013 shall be enclosed or covered. This does not apply to those parts of the conveyor belt that are loaded by a hopper or another transshipment system.

4.

The diffusion of dust at transfer points of continuous transport systems shall be avoided as much as possible by:

1

moistening or spraying the transfer points where substances in dust category SC2 are transferred if the products were not sufficiently moistened beforehand;

2

if the measures stated in point 1 cannot be applied or if dust is still visibly being diffused even after these measures have been taken, providing the transfer points where substances in dust category SC2 are transferred with wind reduction screens if this is technically possible;

3

equipping the transfer points of fixed transport systems for substances in dust category SC1 with a housing or dust extractor if this is technically possible. This also applies to dust categories SC2 and SC3 if dust emissions remain visible after the measures stated in points 1 and 2 have been taken;

4

equipping the unloading points of mobile conveyor belts for substances in dust category SC1 with a shield that connects as tightly as possible to the loading point of the next transport system or a dust extractor. This also applies to dust categories SC2 and SC3 if dust emissions remain visible after the measures stated in points 1 and 2 have been taken.

5.

The diffusion of dust during loading and unloading of dust-producing substances using hoppers shall be avoided as much as possible by:

1

fitting the hopper for substances in dust category SC1 with effective baffles or grilles. This also applies to substances in dust category SC2 that are not adequately moistened;

2

equipping fixed hoppers for substances in dust category SC1 with a dust extractor system, unless this is impossible due to location-specific conditions. This measure does not need to be taken if the operator can show that the hopper is used to load and unload substances in dust category SC1 for no more than 10% of the time it is in use.

6.

The diffusion of dust during loading and unloading of dust-producing substances using chutes, filling tubes, filler pipes and conveyor belts shall be avoided as much as possible by:

1

equipping the loading and unloading installation, if technically and operationally possible, with brake plates or modifying its end to limit the diffusion of dust;

2

equipping new loading and unloading installations, if operationally possible, with brake plates or modifying the end of the installation to limit the diffusion of dust;

7.

The diffusion of dust during loading and unloading of trucks and railway wagons with dust-producing substances shall be avoided as much as possible by:

1

for trucks that leave the site, covering a flatbed trailer filled with substances in dust category SC1 with a tarpaulin. This also applies to substances in dust category SC2 if the moisture content of these substances is not sufficient to prevent the diffusion of dust;

2

equipping the drop holes into which dust-producing substances are tipped with baffle plates.

If the loading of the loading body or the transport that leaves the site is carried out by third parties, the staff of these third parties shall be provided with instructions in accordance with point 1.
