Ok guys, this is going to be potentially embarassing for me, so be gentle...
I've been making knives, rings and other assorted things from stainless steel, titanium, and G10/CF for a while now.
My tools consist of a hacksaw, hand files, power drill, dremel, and small benchtop sander/grinder.
I've always worn full eye and respiratory protection(half mask with charcoal filter) when doing anything with the dremel or sander/grinder, as well as when doing *anything* at all with G10/CF/Micarta. My grinding has always been relatively low speed (no sparks at all), with coarse belts for stock removal.
My question is regarding hand sawing and drilling of metals - I've always assumed that the particles/trailings from hand saws and drills were either too large to pose an inhalational issue, or weren't moving at high enough speed to be aerosolized, but is this correct? I've also always assumed that the temperatures generated from hand sawing and low speed drilling weren't high enough to generate any significant fumes, but again, how accurate am I about that?
I've justs been though some of the material safety sheets on steel and titanium, which primarily mentions inhalational hazards with welding and high speed grinding, but the also mention 'cutting', though not whether this is high speed machine cutting, or something else.
I've been getting a bit of a cough with increased phlegm lately, so have been getting paranoid - there's been some controlled burning of grassland nearby lately as well, so it might be that, but always pays to be safe...
Thanks!
Dave
