- 第1供給源から酸素置換気体を供給することによって保護領域内の酸素濃度が所定の期間にわたって動作濃度(BK)以下の制御濃度(RK)に維持される、密閉された保護領域内における火災の危険性を減少させるための不活性化方法であって、
前記第1供給源が故障した際に前記酸素濃度の成長曲線が前記保護領域に対して定義された制限濃度(GK)に所定時間で達するように、前記制御濃度(RK)及び前記動作濃度(BK)が、前記保護領域に対して定義される設定濃度(AK)以下まで低下され、
前記設定濃度(AK)と前記動作濃度(BK)との間のマージンが故障安全マージン(ASA)に相当し、
前記保護領域内の酸素濃度が、前記制限濃度(GK)より非常に低い制御濃度(RK)まで低下されるように、前記動作濃度(BK)が、前記故障安全マージン(ASA)及び安全マージン(S)分だけ前記保護領域に対して定義される前記制限濃度(GK)より低い値に相当し、
前記制限濃度(GK)と前記設定濃度(AK)との間のマージンが、前記安全マージン(S)に相当する不活性化方法。 - 前記故障安全マージン(ASA)は、前記保護領域における適切な換気回数、及び/又は、前記保護領域と周囲領域との間の圧力差を考慮して決定される、請求項1に記載の不活性化方法。
- 前記故障安全マージン(ASA)は、前記保護領域におけるn50値、及び/又は、前記保護領域と周囲領域との間の圧力差を考慮して決定される、請求項1に記載の不活性化方法。
- 火災パラメータを検知するための検知器が備えられ、
前記保護領域内の酸素濃度は、前記酸素濃度が予め高かった場合に、ぼや又は火災を検知することによって急速に前記制御濃度に低減される、請求項1から3の何れか一項に記載の不活性化方法。 - 前記制御濃度(RK)の前後において±0.2体積%の酸素濃度の制御範囲が提供される、請求項1から4の何れか一項に記載の不活性化方法。
- 前記保護領域内の酸素濃度は、前記換気回数、及び/又は、前記保護領域と周囲領域との圧力差に対して制御される、請求項1から5の何れか一項に記載の不活性化方法。
- 前記保護領域内の酸素濃度は、前記保護領域のn50値、及び/又は、前記保護領域と周囲領域との圧力差に対して制御される、請求項1から5の何れか一項に記載の不活性化方法。
- 前記保護領域内の制御濃度(RK)を維持するための消火剤の量は、前記目的領域の換気回数、及び/又は、前記目的領域と周囲領域との圧力差に対して算定される、請求項1から7の何れか一項に記載の不活性化方法。
- 前記保護領域内の制御濃度(RK)を維持するための消火剤の量は、前記保護領域のn50値、及び/又は、前記目的領域と周囲領域との圧力差に対して算定される、請求項1から7の何れか一項に記載の不活性化方法。
- 前記第1供給源は、少なくとも、酸素置換気体を製造するように設計された装置、圧縮不活性気体容器のアレイ、バッファ容器または脱酸素装置である、請求項1から9の何れか一項に記載の方法を実施する装置。
