I have a minor issue at the moment regarding exposure to glass dust. I am confident that because the task is very infrequent and the exposure time is minimal (no longer than 3 minutes) there are probably no health issues. I could put this to bed by air monitoring. I wondered if anyone out there could throw any light on the following What would i monitor for; General dust or silica (amorphous or fused respirable dust - its definately not crystalline)? Given the exposure time would any tangible results be obtained from gravimetric analysis or would direct reading equipment be more appropriate? Any help on this would be appreciated
