After a chemical burn, first clean up the residual chemicals on the exposed body, and then rinse with cool water.
1. Promptly clean up the residual chemicals: chemical burns are different from burns by hot oil or flames, because the chemicals contain substances such as lime, etc. If you do not clean up with cool water, the chemicals may again produce a chemical reaction, which then produces exothermic, resulting in secondary burns on the skin.
2. Cool water rinsing: chemical burns after rinsing time is generally longer than hot oil or flame burns, generally need to be rinsed for about 1 to 2 hours, rinsing is completed, do not apply purple potion and red potion, etc., and must not be wrapped with dirty cloth.
As chemical burns are generally deeper and may cause damage to some vital organs of the body, such cases should go to a specialized hospital in a timely manner to avoid delaying the best treatment time.
