Is it the heat or is it me? 

We have height adjustable desks and laboratory desks which are currently not inspected under LOLER or PUWER. 

Should they be? 

Can the fabulous IOSH Hive mind help me on this? What does everyone else do?

Thanks in advance, 

I would say no.  By all means have a planned and preventative maintenance and service program in place, including regualr pre-use checks for them, but agree with Hilary with regards to inspections.

LOLER no, but it should be inspected and maintained particularly where it is a powered rather than manual lift.

Personally couldn't justify the extra for an electric push button given the infrequency of adjustment.

Not a LOLER issue due to the type of riser mechanism most use but PUWER yes and they will need inspection to ensure that the mechanism is in good working order.

Although the regs don’t spell this out, LOLER really only applies in situations where you are lifting a load and if that lift should fail someone might be injured eg something fall on them or if they are carrying a person that person falls etc. The rise and fall of desk (and as mentioned a chair) is unlikely to create that sort of risk. In fact I would say that a chair is in more need of routine inspection than a height adjustable desk as I have seen chairs fail and people suffer injuries from such a fall while I am hard pressed to foresee anything involving a height adjust able desk (unless someone was climbing on top of it or something else really stupid)
