Read what the OP said about being able to remove when hot and my response, "You should not be able to remove the cap when hot without being scaled" This is a FACT and there is no debate!

However as I have said and as you know it can be done by gently releasing the pressure and BEING careful I.E not simply removing the cap, even so it still isn't good practice.

Your comment "Yes you can" suggests you are arguing against my valid point to which I have responded!
