at least 150 mm with a maximum gap of 20
mm from the lowest part of the toeboard to the
working surface.
• Safety nets used as edge protection must con-
form to EN 1263-1.
Class A design

• The edge protection openings may not

when intermediate guardrails are used.
• The edge protection openings may not
be more than 250 mm in one direction,
when there is no intermediate guard-
