When you design a workshop if you can put your machines in a seperate room . This usually is not an option for the homeowner but for the professional this is an absolute must.Then when you go into the machine room you ALWAYS wear a trend dust helmet and ear protection , this keeps your bench area relatively dust free and this is where you are for 90% of the time , it also means that other employees/students do not suffer from dust or noise pullution .
Safety first.
