Antenna installation and radiofrequency (RF) work on telecommunications structures is one of the highest-risk activities undertaken in the Australian telecommunications industry. The work involves rigging panel antennas to towers, monopoles or rooftop structures, aligning them to engineered azimuth and downtilt parameters, terminating feeders and jumpers, and commissioning the radio path — all while exposed to electromagnetic energy from co-located transmitters that may exceed ARPANSA general public and occupational reference levels within metres of the radiating aperture.
This SWMS is built around the Work Health and Safety Regulation 2025 (NSW) and its harmonised equivalents in Victoria, Queensland, South Australia, Tasmania, the ACT and the Northern Territory, together with ARPANSA Radiation Protection Standard RPS S-1 (Standard for Limiting Exposure to Radiofrequency Fields – 100 kHz to 300 GHz, 2021) and the Radiocommunications Act 1992 (Cth). It addresses the duties of a Person Conducting a Business or Undertaking (PCBU) under section 19 of the WHS Act 2011 to eliminate or minimise risks so far as is reasonably practicable.
A SWMS is legally required before this work commences because the activity engages multiple categories of High Risk Construction Work under regulation 291 of the WHS Regulation, including work at height with a fall risk greater than 2 metres, work on or near a telecommunications tower, and work on or near energised electrical installations. The SWMS must be prepared, available for inspection, and complied with under regulations 299–303.

Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Obtain a site-specific RF Hazard Assessment and EME report from the carrier before mobilisation; identify all co-located transmitters and their ARPANSA RPS S-1 occupational and general public exclusion zones
- 2Issue a written transmitter shutdown and lockout/tagout request to each carrier; confirm in writing that affected sectors are de-keyed before any worker enters an exclusion zone, and verify with a calibrated isotropic broadband RF probe (e.g. Narda SRM-3006 or equivalent)
- 3All tower climbers must hold current Telco Industry Advancement (TIA) tower climber competency or RIIWHS204E Work safely at heights, plus current rescue from height training within 12 months
- 4Use a dual-lanyard fall-arrest system compliant with AS/NZS 1891.1 with 100% tie-off to a rated anchor; never rely on the antenna mount as an anchor
- 5Conduct a documented pre-climb structural and anchor inspection; reject any anchor without a current engineer's certification
- 6Establish a ground-level exclusion zone with hard barricades and signage extending a minimum of 1/3 the tower height; post a spotter and prohibit unauthorised entry
- 7Use a tagline-controlled capstan hoist or rated gin pole rigging for antenna lifts; tools above 250g must be tethered per AS/NZS 5532
- 8Cease work and descend if sustained wind exceeds 36 km/h, lightning is detected within 10 km (use a handheld detector or BoM lightning tracker), or the structure is iced
- 9Conduct a daily pre-start toolbox talk addressing the RF exposure plan, rescue plan, weather, and individual fitness for work; record attendance on the sign-on register
- 10All workers in potential RF exposure areas must wear a personal RF monitor (e.g. Nardalert XT) set to ARPANSA RPS S-1 occupational thresholds with audible alarm
- 11Implement a documented rescue plan with a second competent climber on site equipped with a rated rescue kit (e.g. Petzl JAG Rescue Kit); maximum suspension time target 10 minutes
- 12Test and tag all electrical equipment per AS/NZS 3760; use only IP-rated tools suitable for outdoor exposure and verify isolation of obstruction lighting circuits before drilling or terminating
Applicable Codes of Practice
Mandatory hierarchy of fall controls for any work above 2 metres on a telecommunications structure
Defines HRCW and SWMS preparation, content and review obligations under Part 6.3 of the WHS Regulation
Sets the basic restrictions and reference levels for occupational and general public RF exposure that the SWMS exclusion zones are calibrated to
Specifies fall-arrest harness, lanyard and energy absorber requirements
Governs anchor selection, system inspection and rescue planning
Anchor rating verification on host structures
Applies the hierarchy of control to RF, electrical and fall hazards
Lockout/tagout of transmitters, rectifiers and tower obstruction lighting
High-Risk Construction Work triggered
Tower climbing, rooftop edge work and working from elevated antenna mounts routinely exposes workers to falls of 10–60 metres or more
The scope explicitly involves climbing and working on greenfield monopoles, lattice towers and rooftop telecommunications structures
Antenna feeders carry live RF energy from co-located transmitters, and the work is performed adjacent to tower obstruction lighting, AC mains and DC rectifier bus systems that cannot always be fully de-energised
Because the work falls within three categories of HRCW under regulation 291 of the WHS Regulation 2025, a SWMS must be prepared before work commences, kept available for inspection by an inspector at the workplace, complied with at all times, and reviewed if controls are revised, an incident occurs or a worker raises a concern. Failure to do so attracts penalties of up to $7,200 for an individual and $36,000 for a body corporate under regulations 300–303, with higher Category 1 and 2 offences under sections 31–33 of the WHS Act 2011 (NSW) where reckless conduct exposes a person to risk of death or serious injury.

Worked example
A two-person rigging crew is engaged by a Tier-1 carrier to swap four legacy 3G panel antennas for new 5G massive-MIMO panels on a 45-metre lattice tower in regional NSW that is co-located with an FM broadcast transmitter. Before mobilising, the lead rigger reviews the carrier's EME report, identifies that the FM transmitter creates an occupational exclusion zone extending 4.2 metres from its dipole, and submits a written shutdown request. On site, the team conducts a pre-start using this SWMS, sets a 15-metre ground exclusion zone with bunting and a spotter, verifies the FM carrier is de-keyed using a Narda SRM-3006, and fits Nardalert XT personal monitors before climbing. Mid-morning, the personal monitor on the lead rigger alarms unexpectedly. The crew immediately descends to the last safe rest platform, contacts the carrier's NOC, and discovers a neighbouring carrier had remotely re-enabled a sector. The SWMS-mandated stop-work and verification protocol prevented an overexposure incident. The shutdown is re-confirmed in writing, the personal monitor is reset, and work resumes. The event is recorded on the SWMS as a control review trigger under regulation 302.

Frequently asked questions
Do I need a separate SWMS for each tower site?
The SWMS must be specific to the work and the workplace. This template is engineered for antenna installation work generally, but regulation 299 requires you to tailor it to each site by inserting the site's EME report findings, structural anchor certifications, exclusion zone dimensions and identified co-located transmitters before work commences.
Who is legally responsible for verifying the RF transmitter shutdown?
Under section 19 of the WHS Act, the PCBU performing the climbing work must verify isolation — you cannot rely solely on the carrier's verbal assurance. The SWMS requires written confirmation from each affected carrier plus on-site measurement using a calibrated broadband RF probe before any climber enters an exclusion zone.
Does ARPANSA RPS S-1 apply if I'm only on the tower for 5 minutes?
Yes. RPS S-1 reference levels are time-averaged over 6 minutes for occupational exposure, meaning a brief but intense exposure within an active main beam can still exceed the basic restriction. Personal RF monitors set to occupational thresholds are mandatory regardless of task duration.
Is a tower rescue plan really required, or is calling 000 enough?
Calling 000 is not sufficient. Regulation 80 of the WHS Regulation and AS/NZS 1891.4 require that a person who falls and is suspended must be rescued promptly to prevent suspension trauma, which can be fatal within 15–30 minutes. A second competent climber with a rated rescue kit must be on site for the duration of the work — this is built into the SWMS.
Can the SWMS be signed digitally by workers?
Yes. Regulation 300 requires that workers be made aware of the SWMS contents and that the SWMS be available for inspection. Digital sign-on is acceptable provided the record identifies each worker, the date, and is retrievable for the duration of the work and for at least 2 years after a notifiable incident.
Does this SWMS cover rooftop antenna work as well as greenfield towers?
Yes. The hazard register, controls and HRCW categorisation apply equally to rooftop monopoles, lattice towers and building-mounted antenna structures. You should add site-specific hazards such as roof penetrations, asbestos roofing on pre-1990 buildings, and edge protection arrangements during site customisation.
