nuodingųjų medžiagų debesis statusas T sritis apsauga nuo naikinimo priemonių apibrėžtis Užterštas nuodingosiomis medžiagomis ir slenkantis pavėjui oro debesis. Skiriamas pirminis nuodingųjų medžiagų debesis (susidarantis cheminio ginklo panaudojimo arba cheminės avarijos metu) ir antrinis nuodingųjų medžiagų debesis (susidarantis garuojant skystoms kovinėms nuodingosioms medžiagoms arba išsiliejusioms PChM). Panaudojus patvariąsias nuodingąsias medžiagas, susidaro pirminis ir antrinis nuodingųjų medžiagų debesis, nepatvariąsias – tik pirminis nuodingųjų medžiagų debesis. Įvykus cheminei avarijai nuodingųjų medžiagų debesis darosi priklausomai nuo PChM virimo temperatūros ir saugojimo sąlygų. Jeigu PChM turi nelabai aukštą virimo temperatūrą (pvz., chloras ar amoniakas) ir jos saugomos didelio slėgio rezervuaruose arba izoterminėse saugyklose, avarijos atveju susidaro pirminis ir antrinis debesis. Jeigu PChM turi aukštą temperatūrą (pvz., sieros rūgštis, tetraetilšvinas), susidaro tiktai antrinis nuodingųjų medžiagų debesis. atitikmenys: angl. chemical cloud rus. облако ОВ
