Hot-side aeration

Q

When do you need to worry about hot-side aeration (HSA)? I realize that after the boil one needs to be careful not to aerate the wort until it is cool, but do you need to be concerned while mashing your grains? If so, at what temperature does HSA become an issue?

 

A
Re-using yeast, storing hops and sanitizing bottles
