What to do in the event of a sting?
in case of sting, the following rules should be followed, in this order:
- Isolate the victim from the danger and quickly remove him or her from the water
- Call for help
- Lay the victim down in a half-sitting position and avoid any effort
- Immobilize the affected limb
- Clean the wound
- The venom of this species being thermolabile, it can be neutralized if it is submitted to a temperature of about 45 °C. It is therefore possible to heat the wound. This popular technique should be practiced with great care so as not to aggravate the wound by burning it. It is advisable to immerse the affected limb in hot water.
- If the puncture is too deep, heating the wound will be less effective.
Sometimes the sting can cause discomfort or even loss of consciousness in the victim. The stings are usually very painful.
