Kungani Ukubhala Kwemithambo Yomthambo Wokusebenza Ngamathambo Amanzi Kusiza Ekuphakanyiseni Kuphatha Kwesikhathi Sokusebenza Nokuthuthukisa Umsebenzi

Ukunciphisa Isiphelo Sokusebenzisa Ngamandla Nokufatwa Kwesikhathi Sokusebenza

Imithambo yomthambo wokusebenza yezindawo ezingaphambili kuyabona ukuthi kubonakala kakhulu ekubhala ngazo nasekubhaleni kuzo abasebenzi. Ngokwesibonelo sesidatha esishiywe ngu-UK Health and Safety Executive ngo-2023, abasebenzi abasebenzisa imithambo yamathambo amanzi ayisikhathi sobude bafana ngamathambo amanzi angu-25% kunezinye izigaba. Imithambo emisha engeziweyo iyanciphisa umkhondo ngaproximately ama-30 ku-40%, okusho ukuthi umuntu omunye uyakwazi ukusebenzisa lokho okudinga ababili ukusebenzisa ngokuhlanganisa. Lokhu kwenza ukuthi kunciphise isiphelo sokufatwa kwesikhathi sokusebenza, izinkinga zokufatwa kwesikhathi sokusebenza ezinhliziyo, nezinkinga zokufatwa kwesikhathi sokusebenza zokubhala ngokuphambuka kwezindawo zokubhala, nokufatwa kwesikhathi sokusebenza kwezinkinga zokufatwa kwesikhathi sokusebenza zokubhala ngokuphambuka kwezindawo zokubhala.

Umsebenzisi we-UK oyingqayizivele wabhalile ukuthi kukhona ukunciphisa ngama-18% kwezinkinga zokusebenzisa ngamandla emva kokuguqula kumithambo engeziweyo, noma kubhekwa ngabasebenzisi abasebenzisa imithambo engeziweyo ukuthi abasebenzi babheka ngokuphambuka kwezindawo zokubhala.

Ukuhlangana ne-EN 12811-1 kanye nezindlela zokusebenza zika-OSHA

Izilayi zesithili esingaphansi kwezinye zizakhiwe ukuthandaza kunezinkinga eziphakathi kuphela ezifundiswayo ku-EN 12811-1 ngokwesilinganisi sezimali, okuyi-2.5 kN ngameteru omphakathi. Zihlanganisa futhi lokho okuqondwa ngu-OSHA ngokuthi yini okuphelele ukuthi kubhekwe njengokuphelele ukuthi kuthathelwe ngokushaya isikhathi sokuthatha izinto ngokushaya, kuzoba nezinkambiso zabo ukuthi abasebenzi bangelwe ukuthatha izinto ezingaphezulu kwezinkulungwane eziyisishiyimbi (50 pounds) noma kusukela kwezinkulungwane eziyisishiyimbi (22 kilograms). Izilayi zazo zombili ziqhathanisa konke okudingekayo kwezindlela zokubendela phambi kokugqibela, kuvumela amaphuzu akhange akhule kakhulu ngokuthi kubhekwe kwezindlela zokuhlanza okungaphezulu kwe-0.5, nokubamba ubuhlungu nokubamba izinkinga ezingaphansi kwezindlela zokuhlupha njengokufundiswayo ku-ISO 12944. Uma izikampani ziqhathanisa izimali zokuphelele zaseYurope nezaseMerika njengalokhu, kubalulekile ukuthi kusebenziswe isikhathi esifanayo kuzo zonke izizwe kweziprojekthi ezingaphansi kwezizwe eziningi. Izirevisi zezikhathi zezinsiza zezinsiza zezinsiza zazisibonisa ukuthi lokhu kucindezelela izicabha nezindlela zokuphatha ngeminyaka yezinkulungwane eziyisishiyimbi (one-third) kusukela kwezindlela zezinsiza zezinsiza.
