If you have not looked it up yet, the SDS sheet for POR-15 Cleaner says it is composed of: water, potassium hydroxide (caustic), 2-butoxyethanol (solvent) and Ethoxylated Undecyl Alcohol (surfactant). The risk phrases include: Corrosive, Dangerous for the Environment and Harmful if Inhaled. The 2-butoxyethanol carries some significant health hazards so please don't do this again.

At least you didn't get any on your hootus..............right?

Did it have anything to do with soaking his hands in cider?

:cool:

I’ve had similar symptoms with lacquer thinner and brake cleaner. Used it for years on the cars and parts.

Now I get awful itching and swelling for a week if I get it on my hands.

Nitrile gloves every time for me now.

In the biz, we talk about 'breakthrough' protection in gloves. In short, how long does it take something to get from the outside to the inside of the glove measure in minutes. In the case of nitrile gloves and most solvents, the breakthrough time is essentially zero. They are great and I highly recommend the use of nitrile gloves, do not get lulled into a false sense of security that you are 'protected'. You will still want to change them and wash the hands well when done.

Acetone goes through nytrile like water through a hose. Latex will stop it for a while. Hydrocloric acid will make latex gloves cry like a baby, but nytrile will stop it.

Gloves make no sense sometimes :D

many years ago I was wearing 1/16" thick PVC "acid" gloves similar to the ones pictured below, working around trace hydrofluoric acid (alien acid, eats through glass and 316 stainless steel like butter).
Several hours later I was getting calcium gluconate shots in my knuckle with a needle they stole from Dr. Frankenstein.

They air-tested the gloves and found no holes or damage, the acid just got through the acid-resistant material.

The running joke from the guys who worked wit HF all the time: HCL or sulfuric? I put that stuff on my cornflakes!

Hydrofluoric acid is something that I consider as "other" in that nothing you normally use to protect yourself from acids will work. I have a turn of the century container for HF that is made of wax. Glass does not work and plastics had not been invented yet. The running joke in our local HazMat team is that if a tanker truck full of HF headed to one of the refineries crashes, we all will just up and resign rather than have to deal with that mess. It is also very common in alloy wheel spray cleaners so be very careful out there.

^^^ That's pretty scary. Is there still HF in there?

When I was a little boy my mother had frozen a two liter ice cream container of water. I thought it looked like a giant sized ice block and licked it. I had to wait half an hour for my mom to get home so she could un-stick my tongue from it LOL

Nope. Thankfully it is empty. Got plenty of other bottles in in the hands of 20 year old undergraduate students though. Yay for me!

until 2004, I worked at a refinery that had up to 20,000 gallons of the stuff on-site.
I read the environmental impact report of a worst case scenario of uncontrolled loss of containment.

I lost sleep over that. As in actually couldn't sleep that night and had trouble the next.
With normal prevailing winds and total loss of containment, predicted death-toll was ...... hard to fathom. wildest nightmare, unbelievable ... more than the population of several of our smaller states.

Of course there were many elaborate systems to prevent a total loss of containment such as rapid transfer pumps, deluge systems, etc. and since then they converted to a safer version of HF that raises the boiling point to 72 degrees F (from 54 degrees) but still .......

^^^ Please tell me said refinery was NOT on the Houston Ship Channel. Or maybe don't tell me. Ignorance is bliss and all...

We used to mix HF with nitric to strip nickel off magnesium. It amazed me that nitric alone would dissolve magnesium in a heartbeat but add a bit of HF to the mix and it protects the mag completely. I HATED that stuff.

Kevin, I screwed up bigly today......

Just got back from ER, my left index finger is 1/4" shorter. Damn table saw.....

Clearly I got off easy for my mistake. Sorry to hear that dad911

Yeah, me too on the 'sorry'. Most tools can put the hurt on you but the TS and bandsaw can change things in a micro second. As small of a piece of time that is you can still never get it back. When I use my TS all thoughts go out of my mind. Like when welding, you don't think about the weather and how hot you are in your PPE. You are into that bead and nothing else. On the TS you watch that blade right there where the chips are coming off. Nothing else.

However, it's somewhat easier for the mind to wander on repetitive cuts. When that happens you have to turn the TS off and slam your head into a wall (or something along those lines) and say, "GD'ment, don't do that!"

Kevin, hope that's all healed now. GD'ment, don't do that! :D
