I have school job I'm bidding. Its a Ag. shop and it has a welding room that is being classed as a Class 1 Div 1 Group A location.It has welding stations with exhaust fans over them for both gas and arc welding.
Now I look at this as a Class 1 Div 1 Zone 2 area and would like to keep outlets above vapor plane, put can't find vapor plane for Group A gas.
Also it seems strange to have a welding class room a Class 1 Div 1 location.Welding is an ignition source.
