Thank you John,
I totally agree on the need to be careful when you’re painting and it is
necessary to put some pre-thought into fans, vents and filters for
painting an aircraft. I’ve done engineering on only 3 commercial
standard booths and they were for companies that required high volume
constant production painting. If you do your own booth specifically for
water-borne paint and adhere to good filters, there should be no color
leaks outside the booth, and you shouldn’t have to be afraid of the
task. Progressively painting one aircraft doesn’t have to be dangerous
if you take your time and don’t over load the air in exchange. Clear the
booth and place intervals for your painting to avoid concentrations. Use
a HVLP gun or the latest equivalent from DeVilbiss and above all, stay
attentive to what is going on. My overlooking the fans at a critical
time points out human error and under worse conditions, even the best
respirator has limits for your safety if it’s overloaded. This is a
point that cannot be emphasized enough, and the reason I suggested you
consider a cheap home made low-pressure air hood ahead of the respirator.
With a little bit of research you’d find there are no remedies for paint
damaged lungs, and you may have difficulty with breathing 24 hours after
you’ve sucked in chemicals from the paint. From there, you can be dead
within 72 hours, so it’s certainly not something to be casual about.
Do sweat the small stuff!
