INHALATION EFFECTS :吸入的影响

Product is a non-toxic simple asphyxiant. High concentrations may exclude an adequate supply of oxygen to the lungs. Effects of oxygen deficiency resulting from simple asphyxiants may include: rapid breathing, diminished mental alertness, impaired muscular coordination, faulty judgement, depression of all sensations, emotional instability, and fatigue. As asphyxiation progresses, nausea, vomiting, prostration, and loss of consciousness may result, eventually leading to convulsions, coma, and death.

这种产品是一种无毒, 窒息性气体。高浓度的氢气富集会使肺部缺氧。由于其易窒息性而导致的缺氧状况有：呼吸急促，注意力不集中，肌肉的协调性减弱，判断力下降，失去知觉，意识模糊。随着窒息过程的发展，可能会发生恶心，呕吐，虚脱和失去知觉，还会大笑，昏迷甚至死亡。

Oxygen deficiency during pregnancy has produced developmental abnormalities in humans and experimental animals.

INHALATION 吸入

PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE. RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS. Victims should be assisted to an uncontaminated area and inhale fresh air. Quick removal from the contaminated area is most important. Unconscious persons should be moved to an uncontaminated area, and if breathing has stopped, administer artificial resuscitation and supplemental oxygen. Further treatment should be symptomatic and supportive. 在任何过度暴露的事故发生时必须立即通知医疗部门。救援人员必须配备自持式呼吸器。应帮助受伤害人员转移到无暴露污染区域并吸入新鲜空气。其中关键是快速的从污染区离开。将失去知觉的人员转移到污染区域之外，如停止呼吸，应实施人工呼吸并提供氧气。进一步的处理应是对症的和支持性的。

FIRE FIGHTING INSTRUCTIONS:灭火指南

If possible, stop the flow of gas mixture. Use water spray to cool surrounding containers. A water fog may be used to create ventilation. Ventilation fans must be explosion proof.

如果可能的话，停止混合气流动。喷水冷却周围容器。水雾可用于改善通风。通风机械必须是防爆型的。

PRODUCT NAME 产品名称: HYDROGEN 氢

Evacuate all personnel from affected area. Use appropriate protective equipment. If leak is in user’s equipment, be certain to purge piping with inert gas prior to attempting repairs. If leak is in container or container valve, contact the appropriate emergency telephone number listed in Section 1 or call your closest BOC location.

将所有人员疏散到事故区之外。使用适当的防护设备。如果泄漏发生在用户的设备上，在维修前应用惰性气体清洗管道。如果泄漏发生在容器或容器的阀门上，应立即拨打第一部分中所列出的紧急电话或与最近的BOC分部联系。

7. Handling and Storage 操作和储存

Electrical classification:电子分类 Class 1, Group B. 1类，B组

Earth-ground and bond all lines and equipment associated with the hydrogen system. Electrical equipment should be non sparking and explosion proof.

氢系统的所有设备和管路均应电气连通并可靠接地。电气设备应是无火花和防爆型的。

This gas mixture is noncorrosive. However, hydrogen can interact with some metals (hardened steels) to cause embrittlement.

这种气体的混合物没有腐蚀性。但是氢可能会某些金属（硬钢）相互作用而导致“氢脆”。

Use only in well-ventilated area. Valve protection caps must remain in place unless container is secured with valve outlet piped to use point. Do not drag, slide or roll cylinders. Use a suitable hand truck for cylinder movement. Use a pressure reducing regulator when connecting cylinder to lower pressure (<3000 psig) piping or systems. Do not heat cylinder by any means to increase the discharge rate of product from the cylinder. Use a check valve or trap in the discharge line to prevent hazardous back flow into the cylinder.. 只能在通风良好的地点使用。阀门必须有保护帽，除非气瓶阀门已连接到用气管道。不要拖，拉或滚动钢瓶。使用适当的手推车进行钢瓶搬运。当气瓶连接到低压（<3000psig）管道或系统上时，要使用减压装置。不得使用任何手段对钢瓶进行加热以加大气瓶的输气速度。输气时应使用逆止阀或阻火器，以防止回流进入气瓶的危险。

Protect cylinders from physical damage. Store in cool, dry, well-ventilated area of non-combustible construction away from heavily trafficked areas and emergency exits. Do not allow the temperature where cylinders are stored to exceed 130 o F ( o C). Cylinders should be stored upright and firmly secured to prevent falling or being knocked over. Use a \"first in-first out\" inventory system to prevent full cylinders being stored for excessive periods of time.

保护容器免受物理损伤。储存区应凉爽干燥通风，由不可燃材料构建，远离交通拥挤和紧急出口区域。气瓶储存区域的温度不得超过1300F（0C）。气瓶应直立存放，可靠固定，防止倒落或被撞击。满瓶、空瓶应分开存放。以“先进先出”的原则使用，防止满瓶存放时间过长。

For additional recommendations, consult Compressed Gas Association Pamphlets P-9,, P-1, P-14 and Safety Bulletin SB-2.
