LOL, I have worn out about 4 pressure cookers and have a big one for canning.

And I used them almost daily, the only one that ever blew the safety, was too full of beef barley soup.

There is still proof of it on the ceiling by the stove.

I only use mine only for canning so not much chance of the vent getting clogged from that. I do check it every time I can, though.
