Chemical burns can be very dangerous. Some chemicals can "leach" into the skin and cause very nasty skin problems. Did the chemical get well washed off with copious running water?
Most creams don't help if the chemical is still "burning" the skin, and will only compound the problem.
Any business handling chemicals should have emergency showers. Did they have one, and did you use it? The first few minutes after a chemical burn is most important - get the chemical off your skin and clothing!
It sounds like your employer needs a shake-up in their safety handling. Did a doc check you before you went home? If not, they could be in serious trouble withthe saftey authorities, depening on your local laws.
Please let us know how you are prexapses.
