Icya kabiri ni ikibazo cy’imiterere y’akazi n’ikoreshwa ryabyo, kandi ntabwo bikwiriye gukoreshwa mu gukora ku murongo w’ingufu.

Impamvu nyamukuru ni ukugira ngo habeho umutekano mu gihe cyo gukoresha, bityo umuvuduko wo gukurura no gusohora amazi ntube wihuta cyane, bityo ntibikwiriye gukoreshwa mu mishinga yo gukora vuba.
