site of a competent company manager who is familiar with safety alert re-work in shafts and who will inspect the operation.

Lift shafts and service duct riser entrances must be guarded by threeguard rails to a height of 1.5m plus toeboards and material guards as atemporary measure. Lift shafts and major risers entanceesshouldalways , where possible, be fitted with lockable temporary or permanentdoors with a guard rail behind and a notice stating “DANGER openshaft behind doors permit to access required”.

Tradesmen fixing doors to risers/shafts must work off harnesses unlessthere is a platform inside.

Shaft work must be co-ordinated using permits or marked up sketchesas appropriate.

One trade must not work above another in a shaft. If required, a permitsystem must be introduced together with physical sepatration by a crash deck.

Shafts


• Scaffolds erected within shafts MUST be constructed in full compliance with legislation:

– Double guardrails and toe-boards at each boarded lift where gap between scaffold and wall is >75 mm

– Scaffolds must be braced or tied to walls to prevent sway in any direction

Shafts


Unacceptable


• No scaffolder is to erect or remove a scaffold without the aid of a harness. This MUST be agreed with the contractor before work commences.

• A similar rule applies to ALL OTHER WORKERS where there is no guarded work platform.

• NO LONE WORKING will be allowed in or over shafts.• The practice of boarding over shafts and voids at every

other floor level MUST be discontinued.• Greater attention must be given to solidly fixed edge

protection - double guardrail and toe-board

Working in Riser Shafts etc.


• Lighting in shafts must be carefully considered during erection of scaffold and ongoing work.– 20 lux for erecting scaffold– 200 lux for task operations

• The safe provision of lighting MUST be arranged before any work commences.

• One trade MUST NOT work above another in a shaft.• Where there is any possibility of this happening, a permit

system MUST be introduced.• Physical barriers and warning signs MUST be erected

where it is possible to walk under a shaft at ground level.



• Lift shafts and major risers should be provided with lockable temporary or permanent doors.

• Where scaffold barriers are used as a short term measure, a minimum of 3 rails to a height of 1.5m and a toe-board must be solidly fixed.

• A minimum lighting level of 20 lux must be provided at all entrances to a shaft

• Carpenters and others fixing doors to shafts MUST work off harnesses unless there is a platform inside.



Unacceptable


Safety Information Sheet No 1.

Lift Shaft Protection - Paddington - The Point Kone Lifts Ltd have developed an integral steel frame and sliding door, as protection to lift shaft openings against unauthorised access. Where possible these should be installed by the contractor constructing the lift shaft core as soon as the formwork is struck so that the possibility of a fall of person is eliminated.

Steel frame and Sliding door bolted to reinforced concrete lift shaft core.

Warning notice stating Danger Lift Shaft and Keep Access Clear.

• Working in a riser or shaft must be controlled by a permit system.

• Weekly co-ordination meetings must decide who will work within a shaft at any one time to prevent one trade working above another.

• The shaft needs to be dedicated to one trade in writing and marked on a layout plan distributed to all contractors.



Permit to Access

• A procedure must be established to prevent operatives working below each other UNLESS the shaft is fitted with a substantial crash deck to provide safe separation.

• Harnesses must be used, attached to the structure or other proved anchor point where there is a risk of falling.

• Contractor working in the shaft will be responsible for the integrity of any edge protection provided.

• Contractors method statement must be carefully checked before approval is given.

• Consider the possibility of the shaft being a confined space.




Method of Installation of Ducting in the Air-conditioning Duct. Paddington - The Point

Rising Duct protected by a double handrail and toe board. Duct void covered by plywood panels, as size of ducts to be installed, supported by metal angle fixed to the sides of the concrete riser.

Underside of plywood panels as size of ducts to be installed supported by metal angle fixed to the sides of the concrete riser. The angle supports have been designed and positioned to support the ductwork when installed.


Designed Scaffold Fitting for Fixing Handrails in Riser Duct Reveals Lyndon Scaffolding Ltd. have designed the scaffold fitting shown in the photographs as a robust way of fixing double handrails into the reveal opening of a rising duct.

When the handrail is fixed in the fitting the angle tightens into the reveal. The fittings have been tested to 0.5 Tonnes

1. The objective of the riser shaft co-ordinator is to ensure that only one contractor works in a riser shaft at any one time, unless special engineered crash decks are provided between work operations on a high shaft. Two contractors working on the same level may also be acceptable but this must be strictly controlled with permits.

2. A regular meeting should be held with the contractors requiring access and the risers allocated to specific contractors. This should be immediately marked on a plan or noted in minutes that can be taken away from the meeting, and a permit issued.

Duties Of Riser Shaft Co-ordinator


3. The riser shaft co-ordinator should understand the subcontracting arrangements of the contractors, and verify that they have arrangements in place to control access to subcontractors such that one will not be working above the other. Spot checks should be made.

4. On appointment the riser shaft co-ordinator must read carefully safety memorandum 10.03 - Working in Riser Shafts at extreme height.

5 The riser shaft co-ordinator must make arrangements to ensure compliance with safety memorandum 10.03, including daily monitoring.

Duties Of Riser Shaft Co-ordinator


Holes up to 600mm wide (any length) are to have A142 structural mesh cast across the hole and a flush 20mm ply covering, with a ‘HOLE UNDER’ notice. Mesh only to be cut as needed to allow services to pass. One square of mesh to be embedded into slab all the way around the hole.


Holes 600mm wide - 2 m wide (any length) are to have A142 structural mesh cast across the hole and a full scaffold deck at every floor level, firmly fixed down.


Holes over 2m wide are to have a double handrail and toeboard all round and a personnel net and debris net at every second floor.


• All edge protection and hole coverings inspected daily.

• Inspection by contractor responsible for hole maintenance.

• Spot checks by site managers.

• Written Handover procedure implemented when contractor ceases to be responsible for maintenance of holes.

Protection of Holes
