Fragile Surfaces & Roof Work

Identify Fragile Before Anyone Steps On It

Any roof or surface that cannot safely bear the weight of a person and their tools is fragile. In the UAE this most often means fibre-cement sheeting, polycarbonate/GRP rooflights, corroded profiled metal deck, and asbestos-cement sheets on older industrial buildings. No one should step on a roof surface until it has been assessed and confirmed load-bearing in writing.

• Pre-access survey

  Structural/competent-person assessment of the deck before first access

  critical

• Asbestos check

  Asbestos survey completed for pre-2000 industrial roofs before any disturbance

  critical

• Signage at access

  'Fragile roof — do not access without a permit' at every ladder, hatch and stair

  critical

• Rooflights

  Treated as fragile in all cases and covered, guarded or netted

  critical

• Crawling boards / staging

  Load-spreading boards used where the deck cannot be walked on

  critical

• Permit to access roof

  Issued per shift with the access route and controls stated

  critical

Roof Edge and Perimeter Protection

• Perimeter guardrail

  Double guardrail plus toe board at every roof edge where access occurs

  critical

• Free-standing counterweighted systems

  Used only within the manufacturer's slope and wind limits with the correct counterweight count

  critical

• Demarcation zone

  Only acceptable ≥2 m from the edge with a physical barrier and supervision

  standard

• Roof access ladder / hatch

  Guarded landing area with the hatch secured open or closed

  critical

• Materials on roof

  Secured against wind; no stacking against the guardrail or over rooflights

  critical

UAE Heat and Roof Work

Roof surfaces in Abu Dhabi and Dubai routinely exceed 70 °C in summer. This causes burns on contact, degrades harness webbing and ropes, softens membranes so they will not bear point loads, and accelerates heat exhaustion — which is itself a leading cause of falls.

• Midday ban

  No roof work 12:30–15:00 from 15 June to 15 September (MOHRE)

  critical

• Surface temperature check

  Measured before access; membrane work suspended when the surface will not bear load

  standard

• Shade and rehydration

  Shaded rest point and cool water within the work area

  critical

• PPE for hot surfaces

  Heat-resistant gloves and knee protection for kneeling work

  standard

• Equipment protection

  Harnesses, ropes and nets kept off hot surfaces and out of direct sun between uses
