Working at Height
Facade Access, Rope Access & Suspended Platforms
Covers IRATA/SPRAT rope access discipline, suspended (cradle/BMU) platforms and facade maintenance access on UAE high-rise towers, aligned with ADOSH-SF (formerly OSHAD) and Dubai Municipality high-rise access requirements.
v2.0Updated 15 Feb 2026ADOSH-SF v4.1 (February 2026)Learning Objectives

1. Rope Access Team Structure
IRATA/SPRAT rope access on UAE towers requires a minimum three-person team: a Level 3 supervisor, and Level 1 or 2 technicians. The Level 3 supervisor holds current certification, manages the work plan, rescue plan and equipment log, and must be on site whenever technicians are on rope. ADOSH-SF (formerly OSHAD) recognises IRATA and SPRAT certification as the accepted competency standard for rope access on Dubai and Abu Dhabi high-rise projects. No technician works alone; a top-side attendant maintains constant contact.
2. Two Independent Rope Systems
Every rope access task uses two separately anchored systems: a working line with descender/ascender for support and movement, and an independent safety line with a fall arrest device such as a Petzl ASAP. Anchors must be independently rated, tested and never share the same failure point. Ropes are inspected before each use for cuts, glazing, and chemical damage, and are retired after any fall-arrest event or per the manufacturer's service life, whichever occurs first.
3. Suspended Platforms and BMUs
Suspended (cradle) platforms and permanent building maintenance units require daily pre-use checks: suspension ropes, hoist brakes, secondary safety rope with fall arrest device, guardrails, overload cut-out, and anemometer/wind-speed limiter. Operators must hold a valid suspended-access operator certificate. Each occupant wears a full-body harness clipped to an independent secondary rope, never solely to the platform structure, in case of primary suspension failure.
4. UAE Certification and Inspection
Facade access equipment (BMUs, davits, outriggers) requires an annual third-party load test and certification, plus a Dubai Municipality or Trakhees design approval for the building's permanent access system before occupation. Rope access equipment (harnesses, descenders, karabiners) is logged individually, inspected before each use by the user, and formally inspected by a competent person at intervals not exceeding six months, with records retained on site.
5. Weather and Environmental Limits
Rope access and suspended platform work stops when sustained wind speed exceeds 12.5 m/s (approximately 45 km/h), during lightning within 10 km, in heavy rain reducing grip and visibility, or in extreme heat conditions triggering the UAE midday work ban (June–September, 12:30–15:00). Facade glass and cladding create additional hazards from reflected heat and sharp edges, requiring cut-resistant gloves and edge protection on all rope contact points.
6. Rescue Planning
A task-specific rescue plan is mandatory before any rope access or suspended platform work begins, and must achieve casualty retrieval within the accepted suspension trauma window — target under 15 minutes. The rescue plan is rehearsed by the team before starting work on a new building or facade zone, uses equipment already rigged (not called-in equipment), and is documented in the IRATA/SPRAT job-specific risk assessment retained with the permit to work.
