Hi,
The BCBC2018, depending on interpretation, allows horizontal wires on guards located less 4.2m from the adjacent surface. Talking with a couple of jurisdictions in BC, They still don't allow horizontal wires no matter what hight the guard is. I have heard of jurisdiction(s) asking for an engineer to sign off on such guards to be accepted.
The logic against them horizontal cables is that even when installed 4" o.c. and tighten up the wazou, when a vertical force is applied (ei: a kid climbing the guard), the cables flex apart. Plus, the cables loosen over time and need to be retightened.
Are you guys accepting them? is it different in other provinces? Any info would be welcome.
9.8.8.6. Design of Guards to Not Facilitate Climbing
1) Except for guards in industrial occupancies, guards required by Article 9.8.8.1. that protect a level located more than 4.2 m above the adjacent level shall be designed so that no member, attachment or opening located between 140 mm and 900 mm above the level protected by the guard facilitates climbing
