5.1 Handling of hoses
- never exceed the permissible working pressure as stated on hose and/or literature
- avoid any tension (see figure 1) and do not hang any load onto the hose
- never exceed the minimum bend radius as resulting kink will cause failure of hose (see figure
2)
- do not allow hose to contact sharp edges or rough objects (see figure 3)
- avoid any twisting of hose (see figure 4)
- do not run over hose with any vehicle or equipment ! Hoses which are put on the surface of
sidewalk or street have to be suitably protected (see figure 5)
- do not allow hose to contact areas of high temperature such as mufflers, exhaust manifold,
heaters or burners. Protect the hose as shown in figure 6 or install it in sufficient distance from
the source of heat.
- it is not allowed to attach weights to the hoses
- make sure that no objects fall on the hoses.
5.2 Protection of the working area in case of breakdown of hoses
Hoses have to be installed or protected in such a way that dangers are prevented, if possible, in
case of breakdown of the hoses.
Danger can be caused by:
- Uncontrolled hose movement after a hose rupture caused e.g. by external influence.
- Emerging of the pressure medium under pressure.
- Inflammation of pressure medium near igniting sources.
Dangers can be prevented by e.g. protective coverings or shieldings
