Work at Height Safety in Singapore

Why work at height needs a written plan

Falls from height remain one of the most serious risk areas on Singapore worksites. The Workplace Safety and Health (Work at Heights) Regulations require a written Fall Prevention Plan for any work at height where there is a foreseeable risk of a person falling. The plan must identify the hazards, the control measures, the anchorage and equipment, the rescue arrangement, and the competent persons responsible.

Rope access uses two independent ropes — a working line and a safety line — anchored to separate, structurally adequate anchor points. Each technician carries personal fall arrest equipment, descenders, ascenders, back-up devices and a means of self-rescue. The system is designed so that a single equipment or anchor failure does not cause a fall.

Five things owners should ask before any rope work

1. Fall Prevention Plan. Ask for the written plan covering this specific building and scope, including the anchor strategy and the rescue plan.
2. Anchorage assessment. Anchorage points must be load-rated and structurally suitable. The plan should record where the anchors are, who assessed them, and when.
3. Rescue arrangement. A rescue plan must be in place before work starts — not improvised after an incident. A second technician trained for rescue should be available throughout.
4. Permit to Work (PTW). A Permit to Work system is required for higher-risk activities. The PTW links the work scope to the supervisor, the competent person, and the date of validity.
5. Competent supervision and current certificates. Ask which technician will supervise the team on site, what their qualification level is, who issued the certificate, and when it expires.

Fall Prevention Plan — what it should contain

• Scope and location of the work, building name and address.
• Hazard identification: edge falls, dropped objects, swing fall, public access below, weather windows, simultaneous works.
• Method statement: rope access system, anchorage, descender / ascender / back-up device, working line / safety line separation.
• Personal Protective Equipment (PPE): full-body harness, helmet with chin strap, gloves, eye protection.
• Rescue plan and the names of personnel trained to perform it.
• Permit to Work reference, where required.
• Competent person, supervisor and rope access technicians named, with qualification levels recorded.
• Coordination with other trades and with the building manager.

Anchorage and equipment

Anchors must be either purpose-installed structural anchors that have been tested and certified for the load, or existing structural elements that have been assessed by a competent person. Each technician's working line and safety line must terminate at independent anchors so that no single failure leads to a fall. Connectors, slings and edge protection are inspected before each shift.

Equipment is subject to manufacturer service intervals and to a documented inspection regime. Records should be available on request.

Rescue is part of the plan, not a contingency

If a technician is suspended and unable to descend on their own, suspension trauma can develop quickly. The team must be able to retrieve a casualty in minutes, not hours. Rope access teams therefore deploy with rescue capability built in: a rope-access trained rescuer, the equipment to lower or pick up the casualty, and a route to a safe area.

Public protection below

Rope access reduces, but does not eliminate, the risk of dropped objects. Tools should be tethered. Where the work overhangs publicly accessible space, the area below should be closed off with barriers and signage, or works scheduled outside the hours when the public uses that area. The building manager and rope access supervisor should agree the exclusion zone and the signage in writing.

Periodic facade inspection

Owners of older or taller buildings often arrange periodic facade inspections to detect cracking, delamination, sealant failure and loose cladding before any element can fall. Rope access lets the inspector reach the actual surface and document defects with photos.
