I. Ivyerekeye urugendo rw'umutekano w'ingenzi ku bikoresho vy'umuriro muto-
Ivyerekeye urugendo rw'umutekano ku bikoresho vy'umuriro muto -bishingiye ahanini ku ngingo ngenderwako z'igihugu "GB/T 7251.1-2017 Ivyuma vy'umuriro muto -Ivyuma vy'umuriro n'ivy'ugucungera" na "Ivyerekeye Ugukwiragiza Umuriro muto wa GB 50054-2011." Ibisabwa vy’imibare vyihariye ni ibi bikurikira:
1. Imbere urugendo rwo gukoreramwo: Nibura 800mm (akazu gahoraho) canke 1000mm (akazu k’ubwoko bw’ibitabo), kugira ngo haboneke umwanya uhagije wo gukoreramwo abakozi bo gusanasana igihe bacumbitse canke bahagaze (bivugwa muri GB 50054, Igice ca 4.2.5).
2. Urugendo rwo gusanasana inyuma: Nibura 600mm, canke nibura 800mm nimba bisabwa gushika ku muryango w’inyuma.
3. Ubwaguke bw’umurongo wo mu ruhande: Ku bijanye n’imirongo ibiri-, urugendo hagati y’ibitabo rutegerezwa kuba nibura 1000mm; ku ntunganyo z'umurongo umwe-ifatanye n'uruhome, nibura 200mm y'uburebure butegerezwa gusigara ku mpande.
Ibindi vyiyumviro:
- Ibarabara ry'imbere ry'iminota 800 rishingiye ku burebure bw'ukuboko kw'abantu bakuze (hafi 700mm), hariho n'aho umuntu ashobora gukoresha ibikoresho.
- Ivyuma vy'ubwoko bw'ibitabo-bisaba ikindi kibanza kuko ibitabo bitegerezwa kwaguka vyose.
II. Ibisabwa bidasanzwe ku bibanza vy'umutekano biri hejuru y'ibikoresho vy'umuriro muto-
Ivyumba vy'umutekano biri hejuru y'ibikoresho vy'umuriro muto -kenshi birarengagizwa, ariko biratera ingorane zo gukwiragira kw'ubushuhe no kwitandukanya n'umuriro munini:
1. Ivyumba vyo hejuru:
- Ivyuma vy'umuriro muto -: Birengeye canke bingana na 300mm (ibisabwa vyo gukuraho ubushuhe);
- Iyo umurongo w'inguvu nyinshi -uri hejuru y'ibarabara: Urengeye canke ungana na 1200mm (uvuye mu Gice ca 4.3.3 ca GB 50054).
2. Gushiramwo ibikoresho vy’imirongo mu bikoresho vyose: Iyo ibikoresho vy’imirongo bishizwe ku gisenge c’ibikoresho, urugendo ruri hagati y’ibikoresho vy’imirongo n’igisenge c’ibikoresho rutegerezwa kuba Rurengeye canke rungana na 150mm kugira ngo ubushuhe ntibugire ico bukoze ku mikorere y’ibikoresho.
