Who is going to check the gate system to determine if it is in compliance with the new standard?
No one at the present time; however, keep in mind two things: (a) the Consumer Product Safety Commission has submitted a proposed revision to the new International Building Code where, if passed, building code officials would then be inspecting gate systems for compliance where the IBC is adopted and enforced and (b) there is a potential for liability if a gate system is not installed in compliance with UL 325.
