Escalator Installation SWMS

Escalator installation is one of the most hazardous vertical-transport trades on a commercial fit-out, integrating heavy structural rigging, precision mechanical alignment and live three-phase electrical commissioning within a confined, partially-enclosed truss pit. The work routinely involves craning a 4–12 tonne truss into a pre-formed well, installing the step band and chain assembly, fitting balustrade panels and glass, then energising drive motors and safety circuits for load testing. Under WHS Regulation 2011 r291 (and harmonised state equivalents), this work meets multiple High Risk Construction Work triggers — work near energised electrical installations, work involving structural alterations requiring temporary support, and work in or adjacent to a shaft or pit deeper than 1.5 metres. A documented Safe Work Method Statement is mandatory before work commences and must be retained for the duration of the work plus a minimum of two years after a notifiable incident. This template provides a CIH-reviewed framework covering truss-in, step band installation and balustrade glazing across all eight Australian jurisdictions.

Control measures

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

1. 1Elimination — Eliminate hot work on site by specifying factory-welded truss brackets and bolted structural connections in the procurement and shop-drawing phase before delivery.
2. 2Elimination — Remove fall-into-pit exposure by sequencing balustrade dwarf wall installation and perimeter scaffold handrail before truss lift commences and pit covers are removed.
3. 3Substitution — Substitute manual chain tensioning with hydraulic chain tensioning tools rated to chain SWL, eliminating recoil energy from manual lever bar method.
4. 4Substitution — Substitute 415V live commissioning testing with low-voltage proving units and insulated test leads where functional testing of safety circuits permits.
5. 5Engineering — Install certified edge protection (1m high, midrail, toeboard) to AS/NZS 4994.1 around the entire escalator well perimeter before any truss-in work begins.
6. 6Engineering — Use a certified rigger and dogman with engineered lifting study, tag lines on both ends and exclusion zone barricades during truss craning to AS 2550.1.
7. 7Administrative — Implement lockout-tagout to AS/NZS 4836 on all electrical isolators before mechanical work; only licensed electrical workers perform energisation under permit-to-work.
8. 8Administrative — Conduct daily pre-start briefing using this SWMS, sign-on register, and toolbox review of the day's specific task sequence with translated copies for non-English speakers.
9. 9PPE — Mandatory cut-resistant gloves (EN388 4X42C minimum) for glass and chain handling, plus AS/NZS 1337.1 medium-impact safety eyewear during all step band work.
10. 10PPE — Class 5 hearing protection (AS/NZS 1270) during step band run-in testing, plus AS/NZS 1801 Type 1 hard hat and Class 0 electrical gloves during commissioning.

Worked example

On a regional shopping centre refurbishment, a four-person escalator installation crew arrives Monday morning for the truss-in of two parallel escalators between ground and first floor. The supervisor opens this SWMS at the pre-start brief in the site shed and walks the crew through the hazard register on a tablet. The rigger identifies that the mobile crane lift path crosses an active loading dock — the crew updates the exclusion zone control on the spot, escalating to the principal contractor to close the dock for the 90-minute lift window. Each worker signs the sign-on register acknowledging the specific HRCW triggers, including powered mobile plant movement and pit fall exposure. During the truss lower, the dogman notices the second tag line operator is positioned inside the swing arc — work is paused, the SWMS is reopened on the tablet, and the tag line procedure control is re-read aloud before resuming. Later that afternoon when the electrical commissioning crew arrives for step band motor termination, the licensed electrician adds a permit-to-work reference into the SWMS supplementary log, isolates the supply under AS/NZS 4836 lockout-tagout, and the document is countersigned. The completed SWMS, sign-on sheets and daily amendments are uploaded to the project compliance folder that evening for the two-year retention period.
