Trestling more than 3 metres tall must only be erected, altered and dismantled by people who have completed a special 1-day scaffolding training course.
To prevent physically stressful working positions and the risk of falling, BFA Bygge & Anlæg recommends that trestling should only be erected with a maximum scaffolding height of 2.20 metres (measured from any chocks to the scaffolding platform).
If trestling more than 2.20 metres in height is erected, the employer must compile written instructions which describe, together with the manufacturer’s usage instructions, how the work can be carried out properly from the point of view of health and safety. Alternatively, other scaffolding solutions should be selected.
A check will be carried out prior to erection of the trestling scaffolding to ensure that all parts are present and are whole and undamaged. Defective and damaged scaffolding parts will be disposed of. The supplier’s instructions for the checking and inspection of scaffolding elements must always be used. Pay particular attention to how the strength of the scaffolding elements can be checked and inspected effectively with a view to locating weakness and internal corrosion.
Usage instructions in Danish must be available on site. This must specify the permitted flat load and spot load. The usage instructions will be handed out to employees together with specific instructions relating to the task in question.
Erection, alteration, dismantling and use
The trestles must standard a firm, even surface, and also be vertically aligned so that they cannot tilt.
Railings must always be fitted if there is any risk of falling and injury. Railings comprise a hand rail at a height of 1 metre, a knee rail at a height of 0.5 metres and a footboard at min. 0.15 m.
Trestling must always be erected with a secure access route, e.g. with a fixed ladder or stairway hatch in the platform in combination with an appropriate secured ladder.
The supplier’s instructions in respect of loads must be followed when placing materials on the trestling.
Never use boxes, ladders or other equipment to achieve extra working height.
