The hazardous flammable liquids leaked out of containers on the ship that was anchored at a dock in Laem Chabang industrial seaport in Chonburi province, said provincial disaster prevention and mitigation office chief Surinrat Suksap.
She said 94 villagers and students in nearby areas were exposed to the chemicals that spread inland before they were evacuated. Most of them suffered irritation on their skin and some of them had difficulty breathing. They were treated at the hospitals.
Laem Chabang is Thailand's main deep seaport and is located 116 kilometres southeast of Bangkok.
