EWP use by contractors Hello Jan
I make a point of obtaining evidence of training and licences before engaging contractors.
I recently had a similar situation to yours when trying to get a warehouse roof fixed. I choose not to engage the first three contractors I contacted because they either did not have up-to-date training or they had the training but were unwilling to work with me on a risk assessment. Contractor #4 had experience, was prepared to do a risk assessment and agree to a safe work plan as well as refresh his training prior to doing the job!
In terms of EWP training, the NZQA outline recommends refreshers every three years with US23966 "Describe types of elevated work platforms" being a prerequisite for specific work platform training (US23960 for scissor lift and US23962 for self-propelled boom lift).
In addition, self-propelled boom lifts require the use of a safety harness which is covered by US23229 "Use a Safety Harness". This is because boom-lifts can catapult people out.
I found the
ewpa.org.nz website very informative. This organisation aims "to promote and support best and safe practices in the use and maintenance of Elevating Work Platforms".
I agree with Carolyn; by ensuring the contractors have training, the risk to your business is reduced. And yes, anyone telling me that they've been doing this job for 20 years etc is of concern and refresher training can help address any complacency.
All the best
