How well someone does depends on how much asphalt they swallowed and how quickly they receive treatment. The faster medical help is given, the better the chance for recovery. Hot asphalt cools very quickly and is difficult to get off the skin. Serious burns can easily occur from the extreme heat. Construction workers who work with asphalt should wear protective clothing.
Asphalt is hard to swallow, but it may cause serious damage.
Delayed injury may occur, including a hole forming in the throat, esophagus, or stomach. This can lead to severe bleeding and infection.
If asphalt gets in the eye, sores may develop in the cornea, the clear part of the eye. This can cause blindness.
