As far as i'm aware its only an HSE inpector that has the power to legally put a prohibition notice onto a scaffold -or a removal notice in extreame circumstances...the term condemned is not wildly used anymore.
these 2day wonder courses only give the person holding it the proof of competance to inspect a structure, if they, like any other competant person deem the scaffold so unsafe as not to use then they can only advise pulling the tag or ladder untill the faults have been rectified but have no legal authority to "condemn" it, they are however the main contractors appointed person ultimitly responsible for the scaffold to be in a safe order & as such it would be them who would be legally responsible should a defect that they failed to notice & report on, cause a failure in the structure or a dangerous work practice which may cause an injury or death....so of course theyre gonna be all over your scaffold like a rash, but just becauce theyre a safety officer doesnt necessarily mean they know more about scaffolding then you do - so if your 100% certain on the facts or reasons then tell em- theyre soon realise your not such a dumb fcuk & give u a bit more respect
