How dangerous is this thing ?

From what I searched on the net, in powder form it's inhalation is quite toxic. And for some people a simple contact is enough for having an allergic reaction. Assuming you're not allergic, is everyday contact (let's say in the form a manual tool) with it is bad long term ? Or if you were to an open wound/scratch and touch it with a beryllium tool (by accident), with it act as poison too ?
