Unfortunately we have had to remove this topic because it has significantly deviated from the original question into a series of forum rule 2 breaches. Users are reminded that personal criticism of other users is not acceptable behaviour on the forums. There is a clear difference between making judgmental responses about other posters and offering an alternative opinion or experience relating to subject of the topic. We ask that all users consider this point carefully when using the OSH forum" thank you IOSH Moderating Team
