the lids should be boiled for 10-15 minutes, like any other lids. i usually do that just as my simmering time is ending.
i dunno when you are creating a hazard. i know that i haven't had a single jar go off though. i've probably canned a total of about 75 jars of stuff in my life. *shrug*
i think you just have to be quick enough to get it all done while it's REally Hot. don't forget, most air is realively sterile. it's the SURFACES of things that aren't.
a'course, if you sneeze directly into the jar, prior to lidding it, you may have a problem :)
