Worrying about working in a small metal is no different than working in a large metal shop. I work at Evapco. We make commercial refrigeration and heating units like water cooling towers; evaporators; forced draft unit that you see on office buildings, hospitals, etc.
Alot of metal in this place, more than in our smithies. The building is wood/metal construction. I work in the sheetmetal dept. running press brakes, shears and CNC punch machines. All we worry about is shutting the machines down in order to protect the computers.
Only thing to worry about in my smithy is protecting any high dollar machine from a power surge.
