I would appreciate some advice.
A contractor has a task of installing pipework above a grid type suspended ceiling.Due to the roof above the ceiling being pitched, the height above the ceiling to the purlins ranges from 2 metre down to nothing at the eaves.
One section of the ceiling tiles and grid is being removed to enable large diameter pipe to be installed by the use of scissor lift.
The remainder of the area, the ceiling tiles are removed, but due to the size of the area, is impractical to remove all the grid sections.
The contractor will use the scissor lift wherever the height above the ceiling will allow him to reach the purlins from the platform to fit pipe suspension brackets, but where the height is too great, he is considering the use of an extension ladder from the floor, through the grid (with short grid removed for access) to the purlin, footed, whilst he fits the bracket.
The work is short duration (5 minutes) but repeated many times.
Can anyone think of a safer way of doing the job

Steps would be better than an extension ladder, no?
Mobile platform?
What height above FFL is the grid?
What height(s) above FFL is the ceiling?
I had a similar job during my apprenticeship at an airport. Fit conduit above the suspended ceiling - it wasn't a grid and tiles but rows of suspended vertical perforated blocks for acoustic damping and I was given a wobbly pair of wooden steps to do the job with.
I told my boss to get someone else to do it.

The height from floor level to underside of ceiling is 3.35m. We considered stepladders and combi-ladders, but in several places there is fixed plant and equipment on the floor so no space for steps etc.

Hi Barry, I recently saw a mobile platform specifically designed for the work you describe. The edge of the platform followed the slope of the roof and had full guard rails all around the top. I don't know who the supplier was but there must be others that have this type of equipment?
Have you considered the presence of Asbestos within the work?
Regards

We have a similar area in which to work and our solution is the use of rope access techniques.
If it is a 'one-off' job, you can find someone to do the climbing stuff for you. We are developing a need on a more regular basis so we have trained 4 staff who go and do the work when it is required.
If you want more info, contact details of helpful people etc, please do not hesitate to contact me.
Regards
Andy
