HIERARCHY OF CONTROL FOR 

CONFINED SPACE HAZARDS


Before undertaking any work at height, it is important to consider the work to be performed, taking account of any foreseeable hazards arising from that work and establish control measures to be implemented for the safe execution. It is essential that a competent person carries out a suitable risk assessment and prepares the method statement for the work at height. Planning for work at height must consider the hierarchy of preventative and protective measures that are central to the Work at Height.

 

I. Avoiding the work at height - There are few options available to the scaffolding industry which enable the task to be executed without working at height e.g. fixing guardrails to precast stair sections at ground level before craning them into place, thus avoiding the need for the scaffolder to work at height. However, there is greater opportunity to eliminate the need to work at height at the design and planning stages of a project by designers and principal contractors e.g. the preassembling of guardrails to steel beams prior to being installed by the steel erectors will eliminate the need for scaffolders to install them at height. If avoiding work at height is not possible then you must consider the next stage of the hierarchy – prevent falls

II. Prevent the falls - Scaffolding team should consider measures that create a safe zone by preventing falls from height, such as providing adequate work platforms with suitable guardrails or other collective measures, before resorting to personal fall protection equipment (i.e. harnesses). Scaffolders are not permitted to work at height while being exposed to a risk of a fall, without taking appropriate actions to prevent or protect against a fall from height.

 

III. Mitigate the distance and consequences of a fall Whatever methods of work are chosen, if it is not reasonably practicable to prevent a fall, then both the distance and consequences of a potential fall must be minimised. For example, if a fall arrest harness is used with a fixed length lanyard then it should be attached to a suitable anchor point as high above the working platform as practicable, then should a fall occur the distance would be minimal compared with an attachment at foot level. Ensure there is no materials stored in the working area as this will create additional hazard to the working team.

IV. Collective over personal protection equipment’s -  At all stages in the Working at height hierarchy, scaffolding working team must consider collective protection over personal protection equipment’s. This means using measures that protect everyone working at height at all times when in place, such as guardrails or safety nets before specifying personal fall arrest equipment that is reliant on being attached.
