Choyamba, posankha wopanga, muyenera kuyang'anitsitsa mphamvu ya wopanga, kaya ndi ya wopanga kapena wapakati, kaya ndi kampani yovomerezeka kapena malo ogwirira ntchito ang'onoang'ono. Mukatha kudziwa mphamvu ya wopanga, ndi bwino kuyang'ana mitundu yawo yeniyeni ya zotchingira msewu ndi njira zodzitetezera posankha, momwe makasitomala amagwiritsira ntchito, komanso zambiri zokhudzana ndi mayankho, kuti mumvetsetse bwino wopanga.

Chachiwiri, mutadziwa mphamvu ya wopanga ndi zambiri kuchokera kwa makasitomala, ndikofunikira kumvetsetsa bwino za zida ndi luso la msewu woteteza. Zofunikira pakuwoneka nazonso ndizokwera kwambiri. Pakuwunika, muyenera kuyang'ana kukana dzimbiri, kukana asidi ndi alkali, komanso kukana kutentha kwambiri kwa msewu woteteza. Ndi bwino kuyang'ana lipoti lowunikira khalidwe ndi ulemu woperekedwa ndi wopanga mu dipatimenti yowunikira khalidwe. Zikalata, ndi zina zotero, kuti mudziwe bwino mphamvu ya wopanga.

Chachitatu, chotchingira msewu nthawi zambiri chimagwiritsidwa ntchito kwa nthawi yayitali chikayikidwa ndikugwiritsidwa ntchito. Chifukwa chake, ndikofunikira kumvetsetsa nkhani zofunika pambuyo pogulitsa, monga: nthawi ya chitsimikizo, nthawi yomwe ogwira ntchito pambuyo pogulitsa amatenga kuti akonze zowonongeka pa chotchingira msewu, momwe angagwirizane pa kubweza ndi kusinthana, ndi zina zotero.
