How much of the fumes can humans tolerate? Are the fumes harmful? Do
they damage other stuff they come in contact with? Is it OK to put a lid
on the plastic etching pan so as to be able to agitate it without risk
of spilling the etchant?

Use an exhaust fan whose flow rate(cfm) is 10 times the volume of the fume hood, and duct the exhaust outside. The nice thing about having a fume hood, is that it will allow you to experiment with different chemistries.

It's ok to etch the boards outside this time of year in the north east but I will have to work in a closed garage in the winter. What can I do the limit or eliminate the fumes from the process?
