1) fire- calling an ambulance and taking the affected person to the hospital immedietly.
2) road- tieing the wound tightly with a cloth to stop the bleeding.
3) snake bite- sucking the venom from the bit portion and applying turmeric for an instance and immedietly rushing to the hospital
4) dog bite- washing the wound nicely with water and applying a anti septic cream...
