Uckfield Fire Service watch manager Ian Ritchie said as there was no initial explanation for that number of casualties the incident was treated as a potential major chemical incident and numerous Police, Fire and Ambulance vehicles rushed there.
However, he added, it transpired that a daughter of the family had fainted in the heat and cut her head as she fell.
“Her sister then fainted at the sight of the blood and their poor mother then fainted at the sight of her girls collapsed on the ground.
“Normality was restored following some oxygen therapy, precautionary checks of the area and a trip to the hospital for the children.”
The emergency services were called to East Hoathly at 11am on Saturday, July 23.
