One of my absolute favourite misconceptions of the Silver Age of Marvel Comics is the way that asbestos is thrown around as a catch-all substance to retard flames. Yes, asbestos has fire retardant properties - it's how it was used so extensively before the health risks became apparent - but on almost any occasion that you see asbestos used in the comics you should remember that it is a fibrous substance that is responsible for a pretty nasty and fatal lung condition.
So, when the army throw Johnny into an asbestos-lined cell to contain him, you should be able to visualise all those tiny little fibres heading down Johnny's throat and latching onto his lungs.
