KARACHI: Authorities in Pakistan's largest portcity,Karachi, issued an orderon Saturday eveningto collect data on storage conditions of dual-use chemicals, after a devastating explosion at a warehouse storing ammonium nitrate in Beirut last week.
According to Lebanese officials, 2,750 metric tons of ammonium nitrate had been stored without safety measures at a warehouse in the Beirut port where the blast on Tuesday killed more than 150 people, wounded 6,000 and left 300,000 homeless. Karachi, a city of more than 15 million people, has two ports and six industrial areas where the chemical is also stored.
In a letter issued on Saturday, Karachi’s commissioner ordered deputy commissioners and chairmen of the city’s industrial zones to provide details on the storage of ammonium nitrate “and other dual use precursor chemicals,” including the origin and ownership of the chemicals and storage facilities, its quantity, storage period and safety measures in place.
No official or estimate data is available on the quantity of ammonium nitrate stored in Karachi, Dr. Muhammad Yasir Khan from the Department of Chemical Engineering of the University of Karachi told Arab News on Sunday.
The volatile chemical compound is a common agricultural fertilizer, but as a dual-use substance it is also used as an explosive for quarrying and mining, and can be a precursor of chemical weapons.
“This chemical substance has thousands of usages including its use in the production of fertilizers, medicines, pesticide as well as in making improvised explosive device (IED),” said Prof. M. Iqbal Chaudhry, general coordinator of COMSTECH — the Organization of Islamic Cooperation committee on science.
“Special care is being taken of the substance, ensuring it is being safely stored and is not stolen as a small quantity of it can be used in subversive activity,” Prof. Chaudhry told Arab News. “It is safe if uncontaminated and stored properly. But I can have devastating effects, like we saw in Beirut, if not properly stored.”
He added that the compound must not be stored in larger amounts and for longer periods.
The catastrophic Beirut blast alerted several countries. Last week, Indian authorities seized a 740-ton consignment of ammonium nitrate that has for several years been lying at a warehouse in the Chennai port.
Pakistan produces ammonium nitrate both for export and domestic industrial use.
