The High-Tech Development Institute of Kim Il Sung University, the February 8 Vinalon Complex and the Hungnam Pharmaceutical Factory have increased the production of such disinfectants as chlorine peroxide and chlorisocyanuric acid.

The Ryongaksan Soap Factory has mass-produced antiseptic solution and hand-disinfection gels which are much higher than pervious ones in effectiveness.

The railway transport sector, too, has produced antiseptic solution by itself and used them to disinfect passenger cars every day.

Cities and counties of North Hamgyong Province meet the requirement for antiseptic solution with antiseptic solution-manufacturing machines made by Chongjin University of Mining and Metallurgy.

Meanwhile, South Phyongan, South Hwanghae and other provinces have produced tens of tons of antiseptic solution every day by expanding their production capacities.
