yosungirako

The zosungunulira R-4 - ndi inflammable ndi poizoni, choncho ayenera kusungidwa adzatsekeredwa mu chidebe chatsekedwa, kuchokera heaters, chakudya, zipangizo zamagetsi, mu malo kuwerengedwa kwa ana, ndi kupewa dzuwa. Zifika msika muli yopangidwa ndi zisulo kugonjetsedwa ndi zigawo zake. Kuchipinda komwe zosungunulira awasungira, payenera kukhala ngozi moto. Alumali moyo kuchokera tsiku kupanga miyezi 12.
