Current regulations call for all platforms to have a protective barrier around all open sides, consisting of a handrail,
at least one intermediate or knee rail, a toe plate and handrail standards.
The distance between two rails or between the lower rail and the top of an upstand shall be no more than 500 mm.
The top of the handrail shall be a minimum distance of 1100 mm above the top of the floor.

I,Horizontal Work
1. Where there is sufficient room...
(1) Space out stanchions and lay rail tubes alongside where handrail is to be erected.
(2) Pull stanchion onto pipe from either end to opposite where they are to be fixed.
(3) Stand up system and temporarily bolt both end stanchions for safety.
(4) Position and bolt intermediate stanchions. Pack either side of base plate with shims to align system if necessary.
2. Where there is insufficient room ...
(1) Fix the end stanchion securely in position, then feed both handrail and kneerail into stanchion while supporting other
end of pipe until other stanchions can be placed.
(2) Place a brick or similar support under base plate until nex stanchion is fed onto pipe.
(3) Move brick to this stanchion and proceed to pull previous stanchion along pipe to its final position.
(4) Bole loosely and repeat operation as previous sequence.
II, Stairway Work
(1) Start at bottom of first flight and work up for SAFETY.
(2) Bolt bottom stanchion securely in position, then the second stanchion loosely in position.
(3) Feed the pipe down through No.2 stanchion and just enter No. 1 halfway. Allow free end to hang.
(4) Feed mid rail through No.2 stanchion and right through No. 1 approx. 75mm.
(5) Fit and securely fix angle closure bend, either by slip joint and taperpin or tack welding.
(6) Feed and fix additional stanchion and tighten.
