Fall Arrest & Restraint Systems

Harnesses, lanyards, self-retracting lifelines, anchor points and horizontal lifelines — clearance calculations, 6-monthly thorough examination, LOLER-style records and the UAE competence expectations.

Which rules apply: Abu Dhabi vs Dubai

The ADOSH-SF references on this page (CoP 23.0, CoP 26.0 and CoP 37.0) are Abu Dhabi instruments issued under the ADOSH-SF Occupational Safety and Health System Framework, and they are what an Abu Dhabi inspector will audit fall arrest & restraint systems against.

In Dubai the equivalent legal reference is the Dubai Municipality Code of Construction Safety Practice, with Trakhees EHS requirements in PCFC areas and DDA rules in Dubai Development Authority areas. Other emirates apply their municipal building-permit safety conditions — Sharjah uses OSHJ-CoP-04, RAK free-zone projects use the RAKEZ HS&E Construction Regulations. Federally, MOHRE Ministerial Resolution 32 of 2022 applies everywhere.

The controls below are technically equivalent across emirates, so ADOSH-SF is widely used as the project benchmark — but cite your own emirate's code on permits, method statements and inspection records.

Restraint vs Fall Arrest

Work restraint prevents a person from reaching the fall edge at all and is always preferable to arrest. A fall arrest system allows a fall and then stops it, imposing forces on the body and requiring a rescue within minutes. If the lanyard can be adjusted so the edge cannot be reached, use restraint.

Preference order
Restraint before arrest; arrest only when restraint is not workable
critical
Maximum arrest force on the body
6 kN (BS EN 355 energy absorber limits force to ≤6 kN)
critical
Attachment point
Rear dorsal D-ring, or front sternal for ladder/rope systems — never a side/belt D-ring for arrest
critical
Side D-rings
Work positioning only — never fall arrest
critical
Body belts
Prohibited for fall arrest; full-body harness (BS EN 361) mandatory
critical

Connectors / karabiners	BS EN 362	Self-closing and self-locking (screwgate or twist-lock)
System selection guidance	BS 8437	Selection, use and maintenance of personal fall protection

Access Equipment — UAE Code References

Personal fall-protection hardware is certified to BS EN standards, but the access equipment itself is governed by the Abu Dhabi ADOSH-SF Codes of Practice (v4.0, July 2024). Dubai sites cite the Dubai Municipality Code of Construction Safety Practice and Sharjah sites cite OSHJ codes for the same equipment; the technical controls are equivalent.

Equipment	ADOSH-SF Code of Practice	Key requirement
Scaffolding	CoP 26.0 — Scaffolding	Erected/altered/dismantled by competent scaffolders under a supervisor; 2.4–2.5 m maximum bay length, 2.0 m lift height; scafftag inspection before first use and at least every 7 days
Ladders and stepladders	CoP 37.0 — Ladders	Short-duration, low-risk work only; BS EN 131 professional class; 1:4 angle, tied/footed, 1 m handhold above the landing, colour-coded pre-use register
Tower cranes (and all lifting equipment)	CoP 34.0 — Safe Use of Lifting Equipment and Lifting Accessories	Annual third-party thorough examination and load test, daily pre-use check, written lifting plan, licensed operator; lifting stops above 38 km/h wind
MEWPs (scissor and boom lifts)	CoP 36.0 — Plant and Equipment, with CoP 34.0 as lifting equipment	TPI certificate, IPAF (or equivalent) operator card plus machine familiarisation, pre-use inspection, restraint lanyard to the basket anchor in a boom lift, written rescue plan
Mast climbers and suspended cradles	CoP 34.0 with CoP 23.0 (Working at Height)	Third-party certified installation, secondary safety device/rope grab, daily pre-use check and rescue arrangements

Anchor Points and Lifelines

Minimum anchorage capacity — per person attached
2,450 kg dead weight per person (approximately 24 kN) — ADOSH-SF CoP 23.0 v4.0 (July 2024), Introduction cl. (d)(iii)
critical
Anchor certification
Designed/verified and certified by a competent engineer before first use
critical
Anchor position
Above the dorsal D-ring wherever possible to minimise fall distance and swing
critical
Horizontal lifelines
Engineered, with sag and end-anchor loads calculated; number of users limited and posted
critical
Prohibited anchors
Scaffold guardrails, ladders, pipework, ductwork, cable trays, rebar cages
critical
Periodic inspection of fixed anchors
Annually by a competent person, with certificates retained
critical
Swing fall (pendulum)
Assessed; keep the work within 30° of vertical below the anchor
critical

Fall Clearance Calculation

The single most common technical failure on UAE sites is clipping on where there is not enough clearance to arrest the fall — the person is stopped by the ground, not the lanyard. Calculate clearance before the work starts and record it in the RAMS.

Insufficient clearance
Use a self-retracting lifeline (typically ~2 m arrest distance) or a restraint system instead
critical
Clearance recorded
Stated in the RAMS and on the work-at-height permit
critical
Obstructions
Scaffold lifts, plant and stacked materials in the fall path assessed
critical

Element (2 m energy-absorbing lanyard)	Allowance
Lanyard length	2.00 m
Energy absorber deployment	1.75 m
Height of worker below D-ring (harness stretch + body)	1.50 m
Safety margin	1.00 m
Minimum clearance below the anchor	6.25 m

Inspection, Examination and Records

Pre-use inspection
By the user before every use — webbing, stitching, D-rings, indicators, connectors
critical
Detailed inspection
At least every 6 months by a competent person, recorded and tagged
critical
Harsh-environment interval
Every 3 months where exposed to UV, sand, chemicals or high humidity — normal for UAE sites
critical
Service life
Per manufacturer, commonly 5 years webbing from first use / 10 years from manufacture
standard
Post-fall
Any component that has arrested a fall is withdrawn permanently and destroyed
critical
Register
Unique ID, date of manufacture, date in service, inspection history for every item
critical
Storage
Clean, dry, out of direct sunlight; never stored in a site container in the sun
standard
