Important changes of guards not to facilitate climbing (New)

Important changes of guards not to facilitate climbing (New):

3.3.1.18.4) Except for guards conforming to Article 3.3.5.10 (for industry occupancy), guards that protect a level located more than one storey or 4.2 m above the adjacent level shall be designed so that no member, attachment  or opening located between 140mm and 900mm above the level protected by the guard facilitates climbing.

9.8.8.6.1) Except for guards in industrial occupancies, guards required by Article 9.8.8.1. that protect a level located more than 4.2m above the adjacent level shall be designed so that no member, attachment or opening located between 140mm and 900mm above the level protected by the guard facilitates climbing.

Designers will have more varieties to design guards because the previous codes were asking all guards not to facilitate climbing, unless it can be shown that the location and size of openings do not represent a hazard. Usually, it is hard for designers to argue with the AHJ about where a hazard is not represented.
