Why would you not recommend it? I will not give up on making PCBs, and unless I know what the "approved methods" are, I will go with this device. Outdoors is not a hazardous environment. Please tell me sir, how do you deal with ferric cloride?

 

Two other possibilities: 1) Do it outdoors; and/or 2) Switch to persulfate.

Persulfate and sulfuric acid are non-volatile.

Outdoors - yes. And working outdoors with this device, even if it stops, it's as simple as walking across the yard or over tree a few feet away from the the etching location and removing the bag. There is nothing to be afraid of here. I will not be afraid of it.

Get your self the proper safety equipment, starting with:

• NIOSH-approved respirator
• Rubber gloves
• Non-absorbent apron
• Safety goggles

A plastic bag over your head attached to a blow dryer at the end of a hose is not the way to be found dead.

 

How can you be dead? please explain yourself.

 

You originally posted a question "Turning a hairdryer into a COOL blower".

If I had known you were engaging in this type of behavior I would have altered my suggestions when helping you out.

Make shift safety equipment is often more harmful in the end because the users are lulled into a false sense of security.

You could end up with a cloud of Ferric Chloride in that bag around your head.
Please reconsider what you are doing.

 

Yes, I know there are safety concerns but it's certainly better than not having anything at all. And if anything goes wrong, I am assuming full responsibility. You have my word on it.

 

If you agree with me, then what is this about?

OOPS ! ! !

Plz do not take foolhardy chances...life is a precious gift!

 

I cannot stop you from making your own decisions, for that I would never be held responsible. I can only suggest what I would; take my words to heart and listen to reason. I would implore you to get proper safety equipment and forget this idea altogether.
That said, I wish you all the health and safety in your endeavors.

Yes, everyone wants to be on the safe side, so I understand the concerns.

 

Say, is persulfate really that much better? I know it's more expensive. And what is NIOSH???

I already have the rubber gloves.

 

NIOSH-approved respirator

National

Kind of the safety standard here in the US

 

Ok, thanks. Best wishes to you too.
