Don't you just love the era of "safety labels"?

Apply a little engineering, a dose of safety and use some caution and
for roving you should be just fine.  My only advise with using any
push up pole is to NOT try and fully extend each section.  I have a
50' Rohn that I've used for numerous things from portable to field
day.  This picture was from FD a number of years ago where we just
threw a 3L 50 and CC A270-10S up not so much for any serious attempt
but to have them on the air. While the pole would extend more we
didn't try fully extending each section to add a little more overlap
and strength since we weren't planning on any guy's.  And it was
strapped to a structural leg of a pavilion.
