您要查找的是不是：
- flammable vapor concentration 易燃蒸气浓度
- Self-contained breathing apparatus in high vapor concentration. 呼吸防护:在高浓度中使用氧气面罩。
- Every effort must be made to avoid spills, regardless of the rate of ventilation, because it is impossible to avoid creating a flammable vapor cloud. 无论通风率怎么样，液氢一旦溅出，不可避免会产生蒸气云，所以必须想尽一切办法避免飞溅。
- Ventilation: positive downdraft exhaust ventilation should be provided to maintain vapor concentration below TLV. 通风：为了使气体聚集程度维持在阀极限值之下，应提供通畅的向下棋流排气通风设施。
- Engineering contacts: If general ventilation is insufficient to maintain vapor concentration below Established exposure limits, use local exhaust ventilation. 如果在不够通风的条件下处理,需要采用一定的通风设备进行处理。
- Experiment results indicate that, at different experiment pressure, the heat transfer coefficient of mixture vapor rise with the vapor concentration depress. 实验结果表明在不同的压力状态下混合蒸汽凝结换热系数随酒精浓度的降低而升高。
