“Little burn pimples”. Depends on how tough your skin might be
.
Some will be more sensitive than others. Most hot chips, as described by the OP, would need to settle on my hands or arms to leave a record. Yes, I do feel them as they bounce off and I do pull my shirt neck tight, to prevent them getting inside! I also wear gloves if hand feeding the long travel, as the hand wheel is directly below the chip fall. I don’t think think a nitrile glove is a danger – I would not wear gloves which can get caught in the moving machinery.
I have a few scars from scrapes and cuts,over the years, but still have all my digits attached – and functioning reasonably – after seven decades of use.
