As I have ground, disc cut and welded Ti a number of times I am interested to know how/why it is cancerous (carcenogenic (might be spelt wrong!)).
If this is the case, as well as explosive!!! there should be some advise available, can the FRA help? this should also be the subject of a new thread in Safety Discussions.
PS keep your drills very sharp and cool.
PPS whilst grinding I set fire to my jeans in the crown jewels department the other day, I was left with a big hole in them!!! The jeans!
