Xidhmada iyo kaydinta, badbaadada
Waxaa lagu soo raray durbaan bir ah oo galvanized 200 litir ah, culeys saafi ah 220 kg/drum.
Lagu kaydiyaa meel qalalan, hadh leh, meel hawo leh.Laga hortagay isku dhaca iyo fallaadhaha qorraxda, weerarrada roobka inta lagu jiro maaraynta iyo dhoofinta.
La kulan dabka saafiga ah ee kulul ama la xiriir wakiilka oksaydhiyaha, oo sababay khatarta gubanaysa.Haddii la kulmo kulaylka sare, cadaadiska ku jira weelka ayaa balaadhay, wuxuu sababay khatarta bamka.
Haddii maqaarku la xiriiro, iska bixiyo dharka wasakhaysan, lagu maydho biyo badan iyo biyo saabuun si fiican.Haddii isha ay la xiriirto, lagu luqluqdo biyo badan iyadoo daboolka isha si ballaaran loo hayo isla markiiba shan iyo toban daqiiqo.Hel gargaar caafimaad.
