It might, however, perhaps suggest that unprofessional engineering is not the major factor, so the accident prevention efforts really should be directed elsewhere - as a noddy example, given the falls data, we might think that periodic inspection of ladders and hand rails by anyone, professional or not, and a process for reporting dodgy situations found is probably going to save more lives than having a professional engineer sign off the original design of them.
