Abstract
Description
(1)フッ化炭素化合物が沸騰した際に、周囲に存在する微量の水素や酸素を取り込んで極めて有害なフッ化水素などのフッ素化合物を生成する危険性がある。
(2)不活性液体中であっても、極めて高速で動作する電子部品の中には、局所では高温に達し、フッ化炭素化合物の沸騰が生じる可能性がある。
(3)冷却系が問題を生じて冷却機能が失われたり、低下したりした際に、設計限界以上に液温が高くなってフッ化炭素化合物の沸騰が生じる可能性がある。
(4)冷却槽の中で電子部品やシャーシの部品が脱落したり、開放系である冷却槽に外からの異物が混入したりした場合に、冷却槽内の局所の液体循環が停滞して局所的に高温になってフッ化炭素化合物の沸騰が生じる可能性がある。
