I admit I'm curious as to what distinction you place between a "PUWER" assessment and a task/activity based assessment using that equipment. PUWER Reg 4 requires: All work equipment must be assessed at procurement stages for: fitness for the conditions in which it is used and determining if your choice of work equipment increases risk to employees’ health and safety. Thereafter, PUWER requires the employer to take appropriate steps to ensure the equipment is used only in the conditions it is suited for. Whole-task assessment should encompass installation, use, maintenance, servicing, emergencies.

this is how I done it in my previous place....although, would a PUWER Assessment be required annually for machinery....or only when a sucificant change has taken place with the machinery or layout of site.....and lastly....would a RA for Forklifts and MEWP be enough, instead of having a PUWER Assessment for the forklifts too
