I find it interesting they made comment to it's effects relative to
Mondays or holidays. Someone in OSHA has a sense of humor.

Ha-ha! Yes, that's funny.

The description sounds familiar. Fortunately for me, I didn't get a
bad dose of it. I didn't have a fever, but it felt like the flu
otherwise.


I remove the zinc coating from galvanized pipe
by allowing the ends to soak in straight muriatic
(pool) acid for a few minutes, then neutralize with
a water and baking soda solution followed by a water
rinse.

The vapor created by the soak is hot, plentiful
and Very Nasty smelling, so I only do this outside
whilst standing upwind.

The resulting steel welds really well. I've avoided
zinc fever so far.

The fumes created by gas cutting powder - coated steel
left my nose offline for most of a year, though.

(Don't do that.)
