Safety
  • DOT label: 易燃液体
  • Health hazard: 注意: 石油原油(UN1267)可能含有有毒的硫化氢气体。吸入或接触材料可能刺激或灼伤皮肤和眼睛。火灾可能产生刺激性、腐蚀性和/或有毒气体。蒸气可能导致头晕或窒息,特别是在封闭或受限区域。灭火或稀释水的径流可能造成环境污染。(ERG, 2024)
  • Hazard summary: 腹腔注射LD50(小鼠)= 220 mg/kg;[RTECS] 引起烧伤;吸入可能对上呼吸道和肺部造成腐蚀性损伤;[Alfa Aesar MSDS]
  • reactive group: 胺类、膦类和吡啶类
  • First aid measures: 参考"一般急救"部分。特定急救:用肥皂和水清洗皮肤。如果烧伤,立即用冷水尽可能长时间地冷却受影响的皮肤。如果衣服粘在皮肤上,不要移除。(ERG, 2024)
  • Harmful effect: 毒性肺炎 - 因吸入金属烟雾或有毒气体和蒸汽引起的肺部炎症。
  • Regulatory information: REACH注册物质: 状态: 活跃 更新: 2014-10-29 https://echa.europa.eu/registration-dossier/-/registered-dossier/11331
  • fire hazard: 高度易燃: 易被热、火花或火焰点燃。蒸气可能与空气形成爆炸性混合物。蒸气可能传播到点火源并回火。大多数蒸气比空气重。它们会沿地面扩散并聚集在低洼或受限区域(下水道、地下室、储罐等)。室内、室外或下水道中存在蒸气爆炸危险。标记为(P)的物质在加热或涉及火灾时可能发生爆炸性聚合。流入下水道可能造成火灾或爆炸危险。容器受热可能爆炸。许多液体将浮在水面上。物质可能在运输过程中处于热态。对于混合动力车辆,还应参考ERG指南147(锂离子或钠离子电池)或ERG指南138(钠电池)。如果涉及熔融铝,请参考...
  • fire fighting: 涉及储罐、铁路罐车或公路罐车的火灾:从最大距离灭火或使用无人主流装置或监控喷嘴。用大量水冷却容器,直到火灾完全扑灭。对于原油,不要直接向破损的罐车喷水。这可能导致危险的沸溢。如果安全装置排气或罐体变色发出声音,立即撤离。始终远离直接接触火焰的罐。对于大规模火灾,使用无人主流装置或监控喷嘴;如果不可能,撤离区域并让火灾燃烧。(ERG, 2024)
  • reactivity profile: 四甲基亚甲基二胺暴露于氧化剂时可能剧烈反应。在放热反应中中和酸形成盐和水。可能与异氰酸酯、卤代有机物、过氧化物、酚类(酸性)、环氧乙烷、酸酐和酰卤不相容。与强还原剂(如氢化物)结合可能产生易燃的氢气。不易点燃,但暴露于热源时可能燃烧。
  • ecotoxicity value: USDA APIS化学品影响:collection=usda_chemeffect&query_type=synonym&query='^51-80-9$'
  • Isolation and evacuation: 火灾:如果涉及罐、铁路罐车或公路罐车,应在所有方向上隔离800米(1/2英里);同时,考虑在所有方向上初始疏散800米(1/2英里)。(ERG, 2024)
  • Air and water reaction: 与空气无快速反应。与水无快速反应。
  • Hazard categories and classifications: 眼睛损伤 1类(69.5%)
  • Non-fire leakage response: 大量泄漏:在液体泄漏前方筑堤以便后续处置。水喷雾可减少蒸气,但在封闭空间中可能无法防止点燃。(ERG, 2024)
  • CSL Reaction Information: 创建日期:5/3/18
  • Personal protective equipment (PPE): 佩戴正压自给式呼吸器(SCBA)。结构消防员的防护服提供热保护,但仅提供有限的化学保护。(ERG, 2024)
