A 12-member Chinese delegation yesterday visited the di-ammonia phosphate (DAP) plant of Di-Ammonium Phosphate Fertiliser Company Ltd (DAPFCL) where an ammonia tank exploded last week, causing at least 50 people to fall sick inhaling toxic gas, reports UNB from Chittagong. The team from China Complant, which helped set up the plant in 2006, along with a high official of Bangladesh Chemical Industries Corporation (BCIC), arrived at the factory on the banks of the Karnaphuli in Anwara upazila around 8:30am, said DAPFCL manager (security) Mofazzol Hossain. The emission of toxic ammonia at the fertiliser factory was brought under control on August 23, some 11 hours after one of two smaller 500-tonne capacity ammonia storage tanks exploded. Fifty people, including women, were admitted to the Chittagong Medical College Hospital (CMCH).
