Richard,
Some time ago I had this issue with some sheet metal parts that were
laser cut. I searched high and low for anything that can classify a
sharp or non-sharp edge. The only thing I could find was related to
toy safety. From what I can remember the lab
I agree with Scott and will try to do better on future correspondences. It
is nice to have the reference even when dealing with co-workers who question
your knowledge or judgement in a matter. It too bad but I have run into this
many times in the past both internally and externally.
PS - Do not
Richard - I would like to know two things:
- what is the preferred radius used?
- what type of tape? can I assume standard masking tape is used?
This would be good info when doing risk assessments. If you have your
information source that would be great, for when I run into the
non-believers.
Thx

give any dimensions.
