General information

Immediate medical attention is crucial in cases of chemical burns. Therefore, it is necessary to show the Safety Data Sheet to medical personnel. Chemical burns must always be treated by a trained physician.


In case of contamination, it is vital to remove the affected person from the source of contamination. Next, it is necessary to move the person to an area with fresh air and ensure that they are positioned comfortably for breathing. Additionally, it is essential to loosen tight clothing and maintain an open airway. If breathing becomes difficult, the affected person may get assistance from properly trained personnel. In case the person loses consciousness, they should be placed on their side in the recovery position, and their breathing must be monitored.


If the contamination affects the mouth, it is essential to rinse the mouth thoroughly with water. If the affected person wears dentures, it is necessary to remove them. Additionally, it is crucial to give a few small glasses of water or milk to drink. However, if the individual feels sick, it is crucial to stop, and vomiting may be dangerous. Medical personnel should be consulted before inducing vomiting. When vomiting occurs, the individual’s head should remain low to prevent vomit from entering the lungs. An unconscious person should be moved to fresh air and kept warm and comfortable for breathing. It is necessary to place an unconscious individual on their side in the recovery position, ensuring that their airway is open.

Skin contact

When dealing with skin contamination, it is essential to remove the substance from the skin immediately. All contaminated clothing should be taken off immediately. Additionally, it is necessary to rinse the skin thoroughly with water for at least 15 minutes. Medical attention is crucial in cases of chemical burns, and only a physician should treat them.

Eye contact

In case of eye contamination, it is essential to rinse the eyes immediately with plenty of water. Contact lenses should be removed, and the eyelids should be held open for at least ten minutes.
