33 4 Safe rf hardware 4.1 General The cntractr is respnsible fr the design, supply and installatin f safety hardware and fall arrest systems t ensure safe access t the prpsed Slar PV installatin area. It is the cntractr s respnsibility t design the prpsed safety hardware and system in accrdance with the apprpriate Australian Standards and regarding their prpsed slar system design. The rf safety hardware system must be designed by a cmpetent persn wh is trained in height safety t AS/NZ1891 and has the experience, knwledge and skills t ensure the pendulum effect is eliminated t the greatest pssible level. The system must be installed by cmpetent height safety installers using NATA apprved prducts which cmply with the lads fr ne and tw persn fall arrest applicatins. The height safety system will cnsist f safe access and egress t the rf ensuring the end user is restrained when at a height f 2m and within 2m f the rf edge. Each cmpnent installed n a rf fr height safety purpses must meet all current lad ratings as stipulated in AS1891:2009. Test Certificates shall be prvided. The installer shall prvide a statement f the systems cmpliance and must install in accrdance t the manufacturer s instructins. The installer cannt use mix & match hardware and must use prprietary hardware t cmply with the Australian Standards. 4.2 Existing rf hardware Where existing rf safety hardware is remved, nt accessible due t the slar installatin, r restricts the current intended purpse f the hardware fllwing slar installatin; it is the cntractr s respnsibility t design and supply replacement safe rf hardware t ensure safe rf access is maintained and the riginal purpse f the safe rf hardware is achieved. The relcated anchr pints/safe rf hardware must include certificatin f cmpliance, a new rigging plan, the same lad bearing ratings t the existing anchr systems and cmply with all apprpriate Australian Standards. There is a strng preference t maintain the existing safe rf hardware by prviding apprpriate slar PV designs and installatin t allw the nging safe usage f the equipment. The design f panel arrays shuld prvide sufficient access t be achieved while tethered with a safety harness t the new r existing anchrs. The rpe arc shall nt be inhibited, and there must be access t walk back t the anchr, detach frm the anchr, then mve safely t the next anchr, tether and mve t the gutter r area required t be accessed. 4.3 Cdes and Standards The design, installatin, materials and equipment shall cmply with the fllwing standards and Cdes: AS 1657 Fixed Platfrms, Walkways and Ladders: design, cnstructin and installatin AS5532 Manufacturing requirements fr single pint anchr devices fr wrking at height AS :2011 Structural designs Part 2- Wind actins AS Steel Structures AS Industrial safety belts and harnesses Australian Standard AS Safety belts and Harnesses Australian Standard AS Hrizntal life line and rail systems 29
