9.10.4 Areas to be protected by Perimeter Safety Net
All areas of the helideck perimeter where a person may fall or be blown off the helideck surface must be protected by a safety net. This includes all the seaboard areas and all inboard areas not protected by handrails, with the exception of access and escapeways.
Consideration should also be given to protecting the areas adjacent to fire monitor / access platforms, but not to the extent that efficient fire monitor operation may be impeded.
9.10.5 Combined Handrail and Safety Nets for Vessels
On vessels, helideck perimeter safety arrangements can be comprised of various systems. These may include:
1.
Permanently fixed safety net around the entire exposed area
2.
Part of the exposed perimeter equipped with a fixed safety net and the remainder with hinged panels
3.
The whole exposed perimeter equipped with hinged panels
4.
In addition to the fixed perimeter safety net sections, removable handrail panels may be provided to give additional personnel protection when the helideck is not in use. This arrangement is seen on smaller vessels with helidecks on the bow section (not elevated) and some aft mounted helidecks.
