4.10 Flat roof installation
4.10.1 Guaranteeing occupational safety
During a flat roof installation, the flat roof is a safety-critical
working area. When installing the product, you must always
comply with these safety regulations:
▶
Ensure that the flat roof can be safely accessed.
▶
Maintain a safety area of 2 m to the fall edge, plus the
clearance that is required for working on the product. The
safety area must not be entered.
▶
If this is not possible, then install technical fall protec-
tion at the fall edge, for example reliable railings. Altern-
atively, set up technical safety catch equipment, for ex-
ample scaffolding or safety nets.
▶
Maintain sufficient clearance to any roof escape hatches
and flat-roof windows. When carrying out the work, use
suitable protective equipment (e.g. barriers) to prevent
you from stepping on or falling through any escape
hatches and flat-roof windows.
4.10.2 Installing the product
1. Use the large rubber feet from the accessories. Use the
