Any health hazards in milliing standard glass fiber PCBs?

[noobCNC]

Other than the standard issues with machining plastics/epoxy such as the volatile organnic fumes/plasticizers that you can breath in, are there health hazards with the glass fibers? E.g. the dust generated containing fine fibers etc. The fibers arnt asbestos but is it normally a problem with milling PCBs especially when you dont know what the epoxy really is that is used in the PCBs?

If you were doing it eight hours a day five days a week without an system to control the dust or without a filter mask you will probably experience problems.

Brief exposure machining a few boards is not particularly hazardous but it is a good idea to use a good filter mask and keep the area well ventilated.

I would install a vacuum that exhaust to outside.

I think breathing in glass dust can lead to Silicosis,
I would think the levels are different for everybody.

A little for you may be way to much for me.

Personally, I would not risk it.

I also intend to make PC Boards and intend
to vent my vacuum to outside to be safe
