Hi everyone,
I did a couple of years work as a hot-dip galvaniser so I thought I'd share a bit of info from when I worked with molten metals.
We were issued elastic sided leather steel toed boots, but the constant heat would shrink the leather and the toe would curl up, making them very uncomfortable. Eventually management supplied thick rubber lace-up boots, with steel toes and a nice thin metal plate embedded in the sole to prevent burn-through if (when) you stepped in a puddle of metal.
For clothes, we got heavy cotton long sleeved shirts and pants mostly, which worked reasonably well for light splashes. Leather aprons were technically available but way too restrictive to be able to do the work we were required to do.
On one occaision we got to trial very expensive 'fireproof' (we were told) shirts. They were heavy, hot and scratchy to wear, but resisted the small splashes better than cotton, however, I was unfortunate enough to receive a much larger than normal splash to the front of my shirt and it actually ignited and sustained the fire. As it refused to be beaten out and there were no fire extinguishers anywhere nearby, I had to rip the furiously burning shirt over my head to get away from the fire. No major injury but the shirt was totally destroyed and I refused to wear another of those.
Minor burns were an almost everyday occurance, major injuries weren't all that rare, and on more than one occaision I had to literally run for my life, so I'm very wary about dealing with molten metal of any kind anymore.
But I do have this weird desire to cast some ali for a project I'm thinking about...
Stay safe.
Regards,
Cogsy.
