A follow up for the group:
I am the human canary who gets headaches consistently from working around
epoxy. I took the following action this weekend:
Total clean up including eliminating the bench wood that had drops of uncured
resin and hardener, removal of all containers to another location, Vacuuming
the entire shop and positive ventilation.
The result this morning was NO HEADACHE! I believe what has been happening is
the epoxy does not cure for quite some time and continues to outgas for
likely 48 hours or so - depending on the shop temperature. In the past, I
would go out and work the following morning thinking the cure was done
overnight and was small - so I wouldn't need a mask.
The new policy will be to leave my lay-ups to do for the end of the weekend's
work and not enter the shop for at least two days, unless wearing the
respirator.
So far, so good. Thanks to everyone who helped with suggestions. I am
encouraged at this point.
