Umthetho Wezi-3 Kuya Ku-1 Wokwakha Izikhafu

‌Incazelo‌

Umthetho ‌3 kuya ku-1 ‌ekuhlanganiseni i-scaffold ubhekisela esilinganisweni esiphezulu esivunyelwe sokuphakama kwe-scaffold kuya kububanzi besisekelo sayo ‌, okuqinisekisa ukuzinza kwesakhiwo. Ngokuqondile:

• ‌Isilinganiso Sokuphakama NobubanziUkuphakama okuphelele kwesikhafu akufanele kudluleUbubanzi besisekelo obuncane obuphindwe kathathu(isb., isikafu esingamamitha ayi-10 ukuphakama sidinga ububanzi besisekelo okungenani amamitha angu-3.3).
• ‌Izinga Lokuphepha‌: Lo mthetho uphoqelelwa yiShayina Ikhodi Yobuchwepheshe Yokuphepha ye-扣件式钢管脚手架(JGJ 130) futhi ihambisana nemikhuba yamazwe ngamazwe yokuvimbela ukuwa725.

‌Injongo‌

• ‌Ivimbela UkugumbuqelaIsilinganiso esiphezulu sandisa ingozi yokungazinzi ngenxa yemithwalo yomoya noma ukunyakaza kwabasebenzi.
• ‌ComplianceUkwephulwa kwemithetho (isb., isilinganiso esingu-1:5) kubangele izingozi, njengokuwa kwe-scaffold engamamitha ayi-10 emimoyeni enamandla25.

‌Izicelo‌

• Izicafu Ezizimele: isilinganiso esingu-≤3:1.
• I-scaffolding enamathiselwe (i-scaffolding yokuphakamisa): ≤2.5:1 isilinganiso 25.

‌Imihlahlandlela ye-OSHA‌

Nakuba i-OSHA ingasho ngokusobala umthetho we-3:1, igcizelela:

• ‌Ukuzinza‌: Izicafu kumele zisekelwe ngokuqinile futhi zifakwe amapayipi.
• ‌Ukuvikelwa kokuwa‌: Izithiyo zokuvikela ziyadingeka ekuphakameni okungu-≥4 feet (ukwakhiwa)‌
