Five Class 12 students sustained injuries in an explosion inside the chemistry laboratory of a school here on Monday, a district official said.
The explosion took place at the Government Senior Secondary School (GSSS) Matiana of Theog sub-division in Shimla during the Class 12 Chemistry board practical examination, he said.
Prima facie, it is suspected that the explosion occurred as the students wrongly combined magnesium nitrate and ferrous sulphate, the school principal informed in writing to the Theog sub-divisional magistrate.
