Lwaki sisaanidde kwesigama ku UL 2034 Carbon Monoxide detector eya mutindo yokka essiddwa ku bbugwe nga nfumba mu kiseera ky’okuziba?¶

Mu mateeka, alamu za standard residential UL 2034 carbon monoxide ziteekebwa mu pulogulaamu nga zilwawo okumala ekiseera ekiwanvu okuziyiza alamu ezitawaanya okuyita mu mukka gw’emmotoka: zikugirwa okukuba ejjembe lyazo wansi wa 30 ppm okumala ennaku 30, ate ku 70 ppm zirinda eddakiika 60 ku 240 (essaawa 1 ku 4) nga tezinnaba kukuba bivuga. Ekisenge ekirimu kaboni monokisayidi wa ppm 65 tekijja kukola alamu ya bulijjo mu kiseera ky’okufumba okumala eddakiika 45, naye ate kiyinza okuleeta okulumwa omutwe, okuziyira, n’obutaba na mukka gwa mukka mu baana abawere, abakyala ab’embuto, n’abalwadde b’omutima. Okukuuma monitor ya digital CO ekola ku bbaatule ng’erina live LCD screen (eraga emitendera egitandikira ku 10 ppm) ku counter kikusobozesa okulaba CO erinnya ku 25 ppm n’oggulawo eddirisa amangu ddala.

Okufumba kwa Vacuum Thermos ("Thermal") kukekkereza kutya ebitundu 80% ku mafuta gange aga sitoovu ey'amangu?¶

Okufumba emmere ey’empeke, pasta, ebinyeebwa ne ssupu tekyetaagisa bbugumu erifumba obutasalako; amazzi bwe gamala okutuuka ku diguli 100 (diguli 212), geetaaga okubeera waggulu wa diguli 85 (diguli 185) okumala eddakiika 20 ku 40 zokka sitaaki ne puloteyina okufumba ddala. Okufumbisa omuceere ku sitoovu enzigule okumala eddakiika 25 kwonoona ebitundu 85 ku 100 eby’amafuta go ng’okyusa ebbugumu eribula mu mpewo ennyogovu mu kisenge. Bw’osooka okubugumya ekyuma ekifuuwa ekyuma ekitali kizimbulukuse eky’akamwa akagazi ng’ofuuwa amazzi agookya, n’ofumba omuceere gwo n’amazzi mu kiyungu okumala eddakiika 2 zokka, n’obiyiwa mu bbugumu erya vacuum erisibiddwa, emmere emala okwefumba munda mu kifo ekiziyiza empewo (vacuum insulation) nga temuli muliro na zero carbon monoxide.
