De obicei, proiectate f\u0103r\u0103 a lua \u00een considerare influen\u021ba gazelor inerte, se calculeaz\u0103 limita inferioar\u0103 de explozie a gazelor de e\u0219apament, iar raportul de dilu\u021bie a aerului se determin\u0103 pe baza rela\u021biei dintre concentra\u021bia gazelor de e\u0219apament \u0219i LEL-ul 25%.

Prin urmare, gazele de e\u0219apament provenite de la sp\u0103larea cu metanol la temperatur\u0103 joas\u0103 nu au limite superioare sau inferioare de explozie.
Cantitatea de aer necesar pentru gazele reziduale de sp\u0103lare cu metanol la temperatur\u0103 joas\u0103 poate fi determinat\u0103 pe baza con\u021binutului de oxigen al gazelor de ardere dup\u0103 oxidarea complet\u0103, care este mai mare de 3%.<\/p>\n
