Maintenance & storage
1. After use, all components must be thoroughly cleaned and inspected before storage.
2. Any damaged parts or components found must be replaced.
3. The manufacturer or supplier must be consulted before repairing scaffold material.
4. Components must be sorted and stacked properly. Take care not to pile the stacks too
high, so that the material lower down in the stacks becomes overloaded and damaged.
If the material must be stacked up high, suitable racking and shelves should be used.
5. Wooden and plastic components (e.g. platforms, toe boards, toe board holders, etc.)
should be stored in a sheltered area so as to maximize their working life.
Wind, ice and snow
During the winter months, when extreme weather conditions can occur, it is important to
remove snow and ice immediately.
With regards to wind loads, ties must be installed every fourth metre in height; see the
section “Bracing and tying-in”. For clad scaffolding, calculations should be made in each
individual case.
For more information, please contact HAKI’s technical department.
