Posted By Philip Roberts Martin, I used to work at a newspaper printing press and we had signs that iluminated when the presses started running but when presses stopped signs switched off automatically. This may solve your problem. best regards Phil Roberts MIOSH

Posted By fats van den raad Martin On the same principle as previous posts with the difference that we linked the illumination of the hearing protection signs to the start-up sequence of the machine. This resulted in the illumination of the signs, a flashing beacon above the sign to attract attention of operators and an audible alarm to warn those that may be in areas where the signs could not be seen. All this also happened before the machine actually started up. It was quite an expensive installation even though we designed and installed it ourselves, but the payback in terms of compliance as well as demonstrating that management are serious about finding sollutions for problems, not just put "blanket policies" in place, was well worth the cost.

If you can't afford the fancy illuminated signs, I see nothing wrong with mandatory signs bearing a written warning of 'when machines in operation' Obviously, training and advice and policy would also ned to reflect this fro all those who have access to the area.
