Safety
  • DOT label: 腐蚀性
  • Health hazard: 有毒和/或腐蚀性;吸入、摄入或皮肤接触该物质可能导致严重伤害或死亡。接触熔融物质可能导致皮肤和眼睛严重烧伤。避免任何皮肤接触。火灾可能产生刺激性、腐蚀性和/或有毒气体。消防或稀释水产生的径流可能具有腐蚀性和/或毒性,并造成环境污染。(ERG, 2024)
  • reactive group: 醚类
  • First aid measures: 参考"一般急救"部分。特定急救:对于腐蚀性物质,如接触,立即用流动水冲洗皮肤或眼睛至少30分钟。可能需要额外冲洗。(ERG, 2024)
  • Regulatory information: 新西兰EPA化学品名录状态:4-甲氧基苯乙酸:无单独批准,但可在适当的团体标准下使用
  • fire hazard: 不燃,物质本身不燃烧但加热时可能分解产生腐蚀性和/或有毒烟雾。有些是氧化剂,可能点燃可燃物(木材、纸张、油、衣物等)。腐蚀物接触金属可能释放易燃氢气。容器受热可能爆炸。对于电动汽车或设备,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)。(ERG, 2024)
  • fire fighting: FIRE INVOLVING TANKS, RAIL TANK CARS OR HIGHWAY TANKS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks in direct contact with flames. (ERG, 2024)
  • reactivity profile: 羧酸在有碱存在的情况下可提供氢离子。它们以这种方式与所有碱反应,包括有机碱(例如胺)和无机碱。它们与碱的反应称为"中和",伴随大量热量释放。酸和碱之间的中和反应产生水和盐。六个或更少碳原子的羧酸在水中的溶解度自由或中等;多于六个碳原子的羧酸在水中的溶解度较低。可溶性羧酸在水中一定程度解离产生氢离子。因此,羧酸溶液的pH值小于7.0。许多不溶性羧酸与含有化学碱的水溶液迅速反应并在中和过程中溶解...
  • 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)
  • Other safety information: 化学品评估:IMAP 评估 - 4-甲氧基苯乙酸:环境一级评估
  • Air and water reaction: 与空气无快速反应。与水无快速反应。
  • Hazard categories and classifications: 急性毒性 4 (> 99.9%)
  • Non-fire leakage response: 消除所有点火源(禁止吸烟、火焰、火花或明火)于立即区域。除非穿戴适当的防护服,否则不要触摸损坏的容器或泄漏物质。如果可以在不冒险的情况下,停止泄漏。防止进入水道、下水道、地下室或密闭区域。用干土、沙子或其他不可燃材料吸收或覆盖并转移到容器中。不要让水进入容器。(ERG, 2024)
  • Personal protective equipment (PPE): 佩戴正压自给式呼吸器(SCBA)。在没有火灾风险时,佩戴制造商特别推荐的化学防护服。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)
