I also want to add something. The new pressure cookers, stovetop or electric, are much less risky than the old school version with the rocker switch. Those could get clogged with food and they had no backup relief mechanism, as far as I know, anyway.
The ones used now have a primary valve that controls the cooking pressure, a secondary valve that will release if the primary fails, and the silicon gasket for the lid, which acts as a tertiary pressure release if the first two fail.
I know some people, like my mother-in-law, have stories of pressure cookers failing and spewing soup at high velocity all over the kitchen. I think that was more of a feature of the older version. And probably required some carelessness to achieve even then.
