3. MEASURES TO PREVENT FALLS
Preventing falls during assembly, modification
or dismantling of the rolling tower
General
Suitable measures to prevent falls must be taken during assembly,
modification or dismantling of the tower. The safety assembly P2
implements these protective measures in full. Depending on the result
of the risk assessment performed, PSA, an AGR or a combination of
both can be used.
Attachment points for the personal
safety apparatus (PSA) on the rolling tower
The rolling tower can also be assembled and dismantled optionally
with personal safety apparatus (PSA). The snap hook must be attached
during ascent at least 1.0 m above the platform area of the level
which has not yet been secured (Fig. 1).
The platform height must be at least 5.75 m. The result is
the minimum attachment height for PSA of 6.75 m (Fig. 2).
