Check-barriers provide a means of temporarily controlling the movement of the movement of the public, for example for restricting admission when checking tickets. Rigid check-barriers should not be provided across any gangway or escape route. Rope and similar barriers should be fitted with automatic catches or slip connections, arranged to part on body pressure and not to trail on the floor when parted; the fittings should not project into the gangway or escape route.

This sounds like stadium walkways and entryways. Humans can crush themselves to death following a concert or sporting event, or in the event of a fire, if the paths are impeded by turnstiles, ropes, fencing, or other barriers. It [getting trapped] happened to me once at Soldier Field in Chicago following a concert--it was terrifying.

The point is to encourage safety.

Rope and similar barriers: that is, barriers that are not rigid (not stiff)

should be fitted with: must have / must be made with

automatic catches or slip connections, arranged to part on body pressure: closing mechanisms that don't need to be manipulated by hand to open them; they should open by themselves when a person pushes against the barrier by walking into it

and not to trail on the floor when parted;: when the barrier is open, the rope or the other non-rigid barrier material can't trail (drape) onto the floor because that would be a tripping hazard

the fittings should not project into the gangway or escape route.: the places where the barriers attach to the wall or any railing must not protrude (must not cause a bump or blockage) into the exit because that will cause a hazard and might slow people down or cause them to fall or be injured if they are pushed against it in a crowd

  • Thanks so much for your detailed explanation. It really helps. – Suya Shao Oct 22 '15 at 1:12
