Chemical burns

[cotter]

Hello

Can anyone possible tell me the concentrations needed to cause chemical burns of the skin from sulphuric acid, hydrochloric acid, and caustic?

Thanks in advance
Cotter

I don't have any specific numbers for you, I just wanted to say that part of the problem depends on how sensitive a person's skin is. For example I've gotten glacial acetic acid on my hands and not had any problems, yet a female classmate of mine got a big ulcerous open wound from the same acid. Concentrated sulfuric acid will take only seconds to burn you. Hydrofluoric acid may not be felt for some time yet it can produce some of the most painful and deadly chemical burns.

From a safety standpoint these are all considered as corrosives down to even a less than 1% solution. Don't even try to cut corners. Just use the appropriate PPE, gloves, apron or splash suit, goggles, and face shield. If mists or gases are involved, You may be looking at moonsuits and SCBA's with full face shields.
