In my circles that is known as a 'meat saw'...it stops when it feels meat! I have been told it will fault on wet wood occasionally too. This is not a bad thing except I have also been told the new brake module is quite $pendy, and must be replaced every time it trips.
In a high school wood shop environment, the poor old brake doesn't stand a chance!
The safest saw on the market is any saw with a safety conscious operator running it.
