Xirmada iyo kaydinta, badbaadada
Waxaa lagu xiray 200 litir oo durbaan bir ah oo galvanized ah, miisaan saafi ah 220 kg/durbaan.
Waxaa lagu kaydiyaa meel qalalan, hadh leh, oo hawo leh. Waxaa laga ilaaliyaa isku dhaca iyo qorraxda, iyo roobka inta lagu jiro maaraynta iyo rarista.
Markay la kulantay dab aad u kulul oo cad ama ay la xiriirto wakiilka oksaydhka, waxay keentay khatarta gubashada. Haddii ay la kulanto kulaylka sare, cadaadiska gudaha weelka ayaa sii kordhaya, taasoo keentay khatarta Bang.
Haddii maqaarku taabto, iska siibo dharka wasakhaysan, si fiican ugu dhaq biyo badan iyo biyo saabuun leh. Haddii isha taabato, ku raaci biyo badan oo indhahaaga si ballaaran loo furo isla markiiba muddo shan iyo toban daqiiqo ah. Raadi gargaar caafimaad.
Fadlan nala soo xiriir si aad u hesho COA iyo MSDS. Mahadsanid.
