the equipment and material to be packed, its handling requirements and kind of
transport chosen.
The packing provides both mechanical and environmental protection.
3.2 Wood treatment
All solid wood,used for packing (including wooden pallets) is treated (heat treatment or
fumigation) according to the international standard ISPM 15 (IPPC),latest revision.
As these rules are not the same for all countries, the procedure is to meet the demands
of a country of final destination.
3.3 Pallets
Equipment is packed on pallets that provide adequate load support during transporta-
tion and storage. The pallets have a dynamic load capacity, enough to carry the mass
loaded on the pallet.
Where feasible the top surface of the pallet must be flat.
The pallet must be tight on all sides with steel or synthetic straps on each side.
Bolts, clamps, supporting beams, etc. will properly fix all equipment and materials.
Fragile, easily damageable and loose parts will be pertaining to the equipment se-
curely and properly packed in a separate case.
3.4 Handling
Under no circumstances may the equipment itself be used as a platform for gaining ac-
cess to installation and construction areas above. If such access is required then suitable
scaffolding must be established, the equipment may not be used as a support.
3.5 Centre of gravity
If required, large and heavy equipment are marked with Centre of Gravity (COG).
3.6 Labelling and tagging of equipment / Identification
If no specific identification is required, (see the Purchase Order for the technical specifi-
cations)the labeling is in accordance to JEVI standard.
