As mentioned in my reply to a post some time back on diynot's forums, the company have to comply with health and safety law and because an accident has drawn blood and therefore is a notifiable accident to the HSE they would be extremely stupid if they didn't put into place a program to stop it happening again or at least to try stopping it happening, now the HSE have been informed they could make a visit to the premises at any time and therefore the company has to cover themselves, nothing silly about trying to stop another person injuring themselves, and it happens to skilled perons aswell so nothing wrong with refresher courses either.
