Okokuqala, lapho ukhetha umenzi, kufanele uhlole ngokucophelela amandla omkhiqizi, kungakhathaliseki ukuthi angomkhiqizi noma ophakathi nendawo, kungakhathaliseki ukuthi ibhizinisi elisemthethweni noma indawo yokusebenzela encane.Ngemva kokunquma amandla omkhiqizi, kungcono kakhulu ukubheka izinhlobo zabo ezithile zemigwaqo egadayo kanye nezindlela zokuphepha zokukhetha, ukusetshenziswa kwamakhasimende, kanye nolwazi lwempendulo, ukuze ube nokuqonda kangcono komkhiqizi.

Okwesibili, ngemva kokunquma amandla omkhiqizi kanye nemininingwane yempendulo evela kumakhasimende, kuyadingeka ukuqhubekela phambili nokuqonda okubalulekile kanye nobuciko be-highway guardrail.Izidingo zokubukeka nazo ziphezulu kakhulu.Ngesikhathi sokuhlolwa, kufanele uhlole ukumelana nokugqwala, ukumelana ne-asidi ne-alkali, nokumelana nokushisa okuphezulu kwe-Guardrail.Kungcono ukubheka umbiko wokuhlolwa kwekhwalithi kanye nokuhlonishwa okwenziwe umenzi emnyangweni wokuhlola ikhwalithi.Izitifiketi, njll., ukuze ukwazi ngokunembe kakhudlwana amandla omkhiqizi.
