Contractor Pre qualification /approval systems I don't think anyone could disagree with all the above comments. I particularly want to expand on Michael's comments about ConstructSafe and SiteSafe. ConstructSafe is a very good independent measure of the applicant's actual knowledge, while SiteSafe simply requires attendance at the training session. Unfortunately ConstructSafe is based on an English system and uses international symbols that are not used in NZ (maybe they should be! - that is a different conversation) and in my experience, many of our staff struggle with them. Also the photos are difficult to interpret without a magnifier.
To me the biggest indicator of the state of our H&S culture is the shear hypocrisy of the concept that without a SiteSafe card you are not safe enough to be let onto site, but if you pay for a course that you haven't yet done, you are now deemed to be safe enough, so come on in!
The reality is that neither qualification actually does anything to improve safety in the workplace.
