Vuba aha, azobisisoheptonitrile yongeye kugaragara mu ruhame. Iyi shimi, ifite izina ry'Icyongereza 2,2′-Azobis-(2,4-dimethylvaleronitrile), igaragara nk'amakristu yera, ifite aho ishongesha hagati ya 40 na 70°C. Ni itangiriro ry'amavuta ashongesha rifite ingufu za 122 KJ/mol. Ishongesha mu bintu bishongesha nk'ibinyabutabire nka methanol, toluene na acetone, ariko ntishongesha mu mazi. Ubushyuhe bwo kubora mu masaha 10 ni 51°C (muri toluene).
Azobisisoheptonitrile ikoreshwa cyane cyane mu gupomera mu buryo bwinshi, gupomera mu buryo bwa suspension na polymerization y'imiti, kandi ikoreshwa cyane mu nganda no mu bushakashatsi bwa siyansi. Kubera ko ibora hafi ya ryose ari igisubizo cya mbere, ikora ubwoko bumwe gusa bwa radical yigenga idafite ingaruka mbi, irahamye mu miterere yayo kandi yoroshye kuyibika no kuyitwara. Ariko, ni ngombwa kumenya ko mu gihe cyo kuyitwara, igomba gushyirwa muri firigo no kurindwa gushyamirana gukomeye no kugongana, bitabaye ibyo ishobora gutera iturika.
Mu gitondo cya kare cyo ku ya 22 Nyakanga 2011, bisi ya double-decker yajyaga iva Weihai, Shandong ijya Changsha, Hunan ku muhanda wa Beijing-Zhuhai Expressway yafashwe n'inkongi y'umuriro. Inkongi yari ikomeye cyane ku buryo yatwitse bisi yaguye ubusa. Iyi mpanuka yahitanye abantu 41 ikomeretsa abantu 6, naho umuntu 1 arakomereka bikomeye. Nyuma y'iperereza, icyateye impanuka ni ugutwara bisi bya shimi byakoreshejwe mu buryo butemewe n'amategeko no gutwara bisi bya shimi bya azobisisoheptonitrile ku modoka yaguye. Iyi miti iteje akaga yaturitse irashya ihita iterwa n'ibintu nko gusohora, gukururana no gusohora ubushyuhe muri moteri, bituma habaho iki kibazo giteye agahinda. Nyuma yaho, abantu babishinzwe batawe muri yombi barafungwa hakurikijwe amategeko. Mu Ukuboza 2013, Urukiko rw'ibanze rw'Umujyi wa Xinyang, Intara ya Henan rwafashe icyemezo cya mbere kuri uru rubanza rw'impanuka, ruhana abantu babishinzwe ibihano bikwiranye n'ibyaha byo guhungabanya umutekano w'abaturage hakoreshejwe uburyo buteje akaga n'impanuka zikomeye.
Iki kibazo cyavuze ko umutekano w’ubwikorezi n’ikoreshwa rya azobisisoheptonitrile ari wose. Ibigo bireba n’abakozi bagomba kubahiriza amabwiriza ajyanye nayo mu gihe bakoresha azobisisoheptonitrile, bakareba ko uburyo bwo gutwara no kubika ibintu byujuje ibisabwa, kandi bakirinda ko impanuka nk’izo zakongera kubaho. Ariko kandi, abaturage bagomba kongera ubumenyi bwabo ku bijyanye n’imiti ihumanya ikirere no kuzamura ubukangurambaga bwabo ku mutekano.
