WARNING
It is important to verify and make sure to remove any gap there may be on the
platform. Cover gaps by adjusting guardrails or by using plywood, planking or
any other strong material. Secure the material in such a way that it remains in
place and does not impede safe circulation on the deck. It is also important to
make sure that all guardrails are properly secured.
