That's not why they're there.As those "security guards" are almost always old men (probably a nure ochiba prevention measure), I doubt their response time in case someone does not "obey".
They're insurance buffers. If someone ignores them, walks in the wrong area, and a load of girders falls on them, then when the family tries to sue the construction company can say, "Hey - we had staff on site telling people not to walk there. Your darling uncle willfully ignored them."
