Data & Network Cabling Installation SWMS

Data and network cabling installation covers the pulling, terminating, testing and patching of Cat6/Cat6A structured cabling through ceiling spaces, cable trays, conduit runs and underground pit-and-pipe infrastructure. The work routinely involves working at height on ladders or scissor lifts, accessing communications pits at ground level, manual handling of large cable drums, and working in close proximity to energised power cabling within shared trays or risers. Under WHS Regulation 2025 a Safe Work Method Statement is mandatory whenever the task involves high risk construction work as defined in Schedule 1 — including work in or near a confined space such as a deep communications pit, work where there is a risk of a fall of more than two metres, and work in proximity to energised electrical installations. ACMA registered cablers must also work to AS/CA S009 and AS/NZS 3080, and the SWMS documents how those technical standards integrate with the WHS hierarchy of control. This SWMS is written specifically for structured cabling crews on commercial fit-out, education, healthcare and data centre projects.

Hazards identified

7 hazards covered, sorted by priority.

Control measures

Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.

1. 1Elimination — Where possible specify pre-terminated trunk cabling assemblies to remove on-site RJ45 termination, fibre splicing and confined space pit work entirely from the scope.
2. 2Elimination — Schedule cabling installation before ceilings are closed and energised power is run, removing fall-through and proximity-to-live-conductor hazards at source.
3. 3Substitution — Substitute heavy 305m reels with 100m boxed cable cartons for above-ceiling pulls, reducing manual handling load below 18kg per single-person lift.
4. 4Engineering — Install cable tray with smooth radius bends, snag-free edges and dedicated communications segregation maintaining 300mm separation from LV power per AS/NZS 3080 Annex.
5. 5Engineering — Use mechanical cable pulling winches with calibrated tension limiters for runs exceeding 30m, preventing both musculoskeletal injury and Cat6A performance degradation.
6. 6Engineering — Deploy tripod-mounted fall arrest, ventilation fans and four-gas atmospheric monitors (O2, LEL, CO, H2S) before any pit entry exceeding 1.5m depth.
7. 7Administrative — Verify ACMA cabler registration for every terminating technician and confirm electrical isolation permits before working in shared risers or near switchboards.
8. 8Administrative — Conduct documented pre-start brief using this SWMS, sign-on register, confined space entry permit and pit rescue plan with nominated standby person.
9. 9Administrative — Rotate termination tasks every 90 minutes and enforce barricading with hi-vis bunting around all lifted floor tiles and open ceiling access points.
10. 10PPE — Issue Class 1 laser safety glasses for fibre work, cut-resistant Level C gloves for termination, P2 respirators in dusty ceiling voids, and Type 1 helmets at all times.

Applicable Codes of Practice

High-Risk Construction Work triggered

Worked example

On a four-storey commercial fit-out, a structured cabling crew is mobilising to pull approximately 180 Cat6A drops from a Level 3 communications room to workstation outlets, with two runs extending to an external pit for a building-to-building link. At the 6:45am pre-start, the supervisor opens this SWMS on a tablet and walks the three-person crew through the hazard register. The team identifies that the external pit is 1.7m deep and has not been entered for six weeks — triggering the confined space control set, so the supervisor schedules atmospheric testing with the four-gas monitor and assigns the second-year apprentice as standby person with the rescue tripod rigged before any entry. The lead cabler flags that the Level 3 riser shares a tray with newly energised submains, so the controls referencing 300mm segregation and electrical isolation verification are reviewed and an electrical permit is obtained from the site sparkie. All three workers sign on to the SWMS register. Mid-morning, a ceiling tile is found removed near the lift lobby with no barricade — the supervisor stops work, references the barricading administrative control, deploys hi-vis bunting and amends the daily site diary. The SWMS is re-briefed at the post-lunch restart because a fourth technician has joined the crew to assist with patch panel termination.
