(1) To avoid the possibility of an explosion, never permit oil to get into any oxygen apparatus.2 u- ~8 V8 h: J0 D) C0 D
(2) Never apply pressures to gauges suddenly. Open valves on cylinders slowly.

虽然说从安全角度出发是为企业负责的一种表现,但是只是强调自认的安全,而忽视企业的感受和承受,是真正的为企业负责吗?谁说一定要检定才能保证安全呢?尤其是这种无法找到明确依据,只能凭借个人理解的“猜测”?
