I may be wrong but I thought these two films had reduced red sensitivity and that's why they are described as orthopanchromatic?

When I used to use B&W film in 120 frequently, usually 400ASA, I often had no choice but to change rolls in direct sunlight, and personally never had a roll fogged though I can see the sense of doing it in the shade if that's available.
