According to Ankleshwar-GIDC police, a barrel containing '4-Hydroxybenzoic Acid' exploded late last night when some of the labourers were weighing barrels of this chemical in the manufacturing unit of Survival Technologies Pvt Ltd, located in GIDC area.
The deceased was identified as Mohammad Zahid Hussain (19), who used to work and live at the factory, said police. Those who are grievously injured are Lalan Paswan, Mitesh Vasani and Prakash Paswan.
"Since Zahid was very near to that drum, he died of severe burn injuries due to the acid, while three others, who were at a distance from the scale, received burn injuries.
"Apart from them, eight other labourers received minor burn injuries. We have lodged a case of accidental death and started our investigation," said Hasoti.
