[ARC5] batteries message Glacial acetic acid eye protection. warning

[Peter Gottlieb]

Sorry yes people should be careful. I work with strong chemicals and understand the hazards and how to be careful and safe but sometimes forget that this is not the case for everyone. 

Treat concentrated acids with extreme respect, wear gloves and a face shield, and remember when diluting to add acid to water not the other way around, etc.

It is a weaker acid than sulfuric or nitric acid. In photography it is usually diluted to 28% as a stock solution and then diluted further for use. Most stop baths are about 2%. White vinegar is about 5% acetic.
