Hi Bruce
I hope you have recovered from your experience.
Thank you for your insight into thermite.
I don't know how the factory where I work hasn't blown up several times
over. We have a welder who is very fond of grinding things after welding,
and as he is the TIG welder he does both aluminium and steel welding and
grinding. I have printed your story out and intend to show it to our safety
officer and if necessary the MD to get safety measures enacted now.
Thanks again,
Graham.
