:blink: i always use glasses and earmuffs when grinding,but never a mask. dont think ive ever seen anyone wear one while grinding.i stupidly thought all the sparks are firing away from me and being metal should be heavy enough not to be airbourne for long.i did alot of grinding today and felt a bit dizzy when i went in the house, so i thought i would do some research and found this.i will most definately be wearing a mask from now on.
thank you IFI you have saved my life!
