潜在危害(火灾与爆炸)

不燃,物质本身不燃烧,但受热可能反应产生腐蚀性和(或)毒性烟气。
Non-combustible, substance itself does not burn but may react upon heating to produce corrosive and/or toxic fumes.
径流可能污染水体。
Runoff may pollute waterways.

健康危害

吸入蒸气或接触该物质会造成沾染并可能产生有害影响。
Inhalation of vapors or contact with substance will result in contamination and potential harmful effects.
火灾会产生刺激性、腐蚀性和(或)毒性气体。
Fire will produce irritating, corrosive and/or toxic gases.

公众安全

拨打 119(火警)/120(急救)/110(报警)。然后拨打运输单据上的应急响应电话号码;如无运输单据或无人接听,请拨国家化学事故应急咨询专线 0532-83889090(24 小时),或查阅封底内页所列的相应电话号码。
CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.
位于上风向、地势较高处和(或)上游。
Stay upwind, uphill and/or upstream.
无关人员远离。
Keep unauthorized personnel away.
立即预防措施
Immediate precautionary measure
向四周隔离泄漏区至少 50 米(150 英尺)。
Isolate spill or leak area for at least 50 meters (150 feet) in all directions.
大量泄漏
Large Spill
考虑在下风向至少 100 米(330 英尺)范围内实施初始疏散。
Consider initial downwind evacuation for at least 100 meters (330 feet).
火灾
Fire
当任何大型容器涉及火灾时,考虑向四周 500 米(1/3 英里)实施初始疏散。
When any large container is involved in a fire, consider initial evacuation for 500 meters (1/3 mile) in all directions.

消防措施

使用适合周围火情的灭火剂。
Use extinguishing agent suitable for type of surrounding fire.
切勿将水直接射向受热的金属。
Do not direct water at the heated metal.

防护服

佩戴正压自给式呼吸器(SCBA)。
Wear positive pressure self-contained breathing apparatus (SCBA).
消防员结构防护服可提供热防护,但化学防护能力有限。
Structural firefighters' protective clothing provides thermal protection but only limited chemical protection.

泄漏处置

切勿触碰或踩踏泄漏物。
Do not touch or walk through spilled material.
未穿着适当防护服时,切勿触碰破损容器或泄漏物。
Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.
在无风险的情况下堵漏。
Stop leak if you can do it without risk.
防止泄漏物进入水体、下水道、地下室或受限空间。
Prevent entry into waterways, sewers, basements or confined areas.
切勿使用钢制或铝制工具、设备。
Do not use steel or aluminum tools or equipment.
用土、沙子或其他不燃材料覆盖,再盖上塑料布,以减少扩散或与雨水接触。
Cover with earth, sand or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain.
对汞,使用汞泄漏处理包。
For mercury, use a mercury spill kit.
汞泄漏区域随后可用硫化钙或硫代硫酸钠溶液洗涤处理,以中和残留汞。
Mercury spill areas may be subsequently treated with calcium sulphide/calcium sulfide or with sodium thiosulphate/sodium thiosulfate wash to neutralize any residual mercury.

急救

通用急救措施(各卡一致(18)
一般急救:
General First Aid:
拨打 120(急救)或呼叫急救医疗服务。
Call 911 or emergency medical service.
确保医务人员了解所涉及的物质,采取防护措施保护自身并避免沾染。
Ensure that medical personnel are aware of the material(s) involved, take precautions to protect themselves and avoid contamination.
在安全可行的情况下,将伤员移至新鲜空气处。
Move victim to fresh air if it can be done safely.
呼吸困难时给予吸氧。
Administer oxygen if breathing is difficult.
如伤员无呼吸:
If victim is not breathing:
切勿进行口对口人工呼吸;伤员可能已吞入或吸入该物质。
DO NOT perform mouth-to-mouth resuscitation; the victim may have ingested or inhaled the substance.
如具备条件且触及脉搏,清洗面部和口腔,然后使用合格的呼吸急救装置(球囊面罩、带单向阀的口袋面罩或其他装置)进行人工呼吸。
If equipped and pulse detected, wash face and mouth, then give artificial respiration using a proper respiratory medical device (bag-valve mask, pocket mask equipped with a one-way valve or other device).
如未触及脉搏或无呼吸急救装置,实施持续胸外按压。每两分钟检查一次脉搏,或观察有无自主呼吸的迹象。
If no pulse detected or no respiratory medical device available, provide continuous compressions. Conduct a pulse check every two minutes or monitor for any signs of spontaneous respirations.
脱去并隔离受污染的衣物和鞋子。
Remove and isolate contaminated clothing and shoes.
少量皮肤接触时,避免将物质扩散到未受污染的皮肤上。
For minor skin contact, avoid spreading material on unaffected skin.
如接触该物质,立即用流动清水冲洗皮肤或眼睛至少 20 分钟。
In case of contact with substance, remove immediately by flushing skin or eyes with running water for at least 20 minutes.
严重烧伤须立即就医。
For severe burns, immediate medical attention is required.
接触该物质(吸入、吞入或皮肤接触)后的症状可能出现延迟。
Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed.
保持伤员安静并保暖。
Keep victim calm and warm.
对伤员持续观察。
Keep victim under observation.
如需进一步救助,请联系当地中毒控制中心。
For further assistance, contact your local Poison Control Center.
注:基础生命支持(BLS)和高级生命支持(ALS)应由受过训练的专业人员实施。
Note: Basic Life Support (BLS) and Advanced Life Support (ALS) should be done by trained professionals.
