+# Usage of Diphoterine
+
+Diphoterine is a decontamination solution used in first aid for the emergency treatment of chemical spills to the eyes and body.
+
+Diphoterine solution contains an amphoteric, chelating molecule: a substance which is capable of reacting with both acids and alkalis when applied to either type of chemical spill, stopping the aggressive action of a corrosive or irritant chemical, halting the reaction with the body.
+
+**Please note that diphoterine is not effective against hydrofluoric acid (HF).**
+
+**In case of skin or mucosa contact with a chemical, always ask for help, ask someone to call 112 and 5555 and use Diphoterine!**
+
+**The helper should call 112 and 5555 and indicate as much details as possible abot the substance splashed (what, how much, chemical or biological).**
+
+**In case of chemical contact, the helper has to download the Safety Data Sheet (SDS) from Quarks and the victim has to have it with him to go to the hospital.**
+
+You can find the Diphoterine  station (orange box) in the Safety points in BT1 and in the laboratories in BT2
