in spray boothes where mineral spirit based material is applied do the emergency stops have to be class 1 div 1 for eplosion proof as well as the conduit having to be rigid threaded conduit
 
What are the emergency stops for? The booth interior is Class I, Division 1. Areas immediately outside booth openings are Class I, Division2.
See article 516 to determine the classified areas. For more info, see NFPA 33 Standard For Spray Application Using Flammable or Combustible Materials.

Depending on what you are "stopping" it may be easier to use pneumatics. Or use a pneumatic pilot to operate a remote electrical switch that can be located outside of the classified arera. Either would be less expensive to install and much easier to maintain.

that's a good point... if it's a conveyor system, with a grab line, putting the
switch on the end of the line not in the booth is a quick fix.

using an intrinsically safe device may also make this simpler.

otherwise, cut, thread, pour seals when done....:D
