There are no panchromatic papers (only film) unless you're are talking about direct-positive papers.
OC filters have nothing to do with orthochromatic vs panchromatic. They are just a compromise between safelight protection and maximizing human visual sensitivity. OC filters are great for many modern papers with very limited red sensitivity (true orthochromatic papers). They are not so good with red-sensitive papers (Foma). A red safelight is always 'safer' than OC filtration, but not as bright to us humans as OC filtered light.
