First Aid for Tar or Plastic Burns - Topic Overview
Immediately run cold water over the hot tar or hot plastic to cool
the tar or plastic and stop the burning.
Do not attempt to peel the tar or plastic off after it has cooled.
This may remove skin that is stuck to the tar or plastic. To remove tar or
plastic, loosen it with mineral oil or ointments such as Vaseline or
Polysporin. Tar will likely peel off after a few days as the skin cells below
the tar flake off normally.
