Industrial hygiene :
Inhaling particles or vapors of beryllium can cause serious damages to your lungs. Nevertheless, risks are minimised in copper-beryllium alloys due to the low levels of beryllium they contain. Most machining processes of beryllium do not augment the concentration of particles in the air. However certain processes are likely to generate particles and vapors, and it is therefore strongly advisable to install an extraction system that will prevent the spreading of harmful agents in your work environment.
