The toxic gas leakage at Sequent Scientific Limited in the MIDC area of Boisar, which killed four persons on Tuesday evening, may have been caused by old, worn out pipes, workers alleged on Wednesday.
“The pipes have undergone wear and tear over the years. Although inspection is done before every batch is manufactured, the pipes are not the focus,” said 22-year-old Sunil Chaurasaia, one of the six workers who were in the reactor room where the hydrogen sulphide gas leaked.
