One big advantage of ProPress piping is the elimination of open flame - important to me, as I work a lot in Hazardous Environments (Flammable gasses). However, what I really need is a ProPress Tool that is UL or CSA listed as explosion proof for Class 1, Div 2 Group D environments; or alternatively, certified as "Intrinsically Safe." Apparently, Rigid does not offer anything like this. Does anyone know if such a tool exists? Or does anyone offer a pneumatically operated tool? Being able to install process piping in "hot" environments without process shutdown or pre-flanged/threaded pieces would be a huge cost saver!
