- Treatment： EYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.
- DOT label： 第9类
- Health hazard： 吸入材料可能有害。接触可能导致皮肤和眼睛灼伤。吸入石棉粉尘可能对肺部造成损害。火灾可能产生刺激性、腐蚀性和/或有毒气体。一些液体产生的蒸气可能导致头晕或窒息。灭火或稀释水的径流可能导致环境污染。(ERG, 2024)
- Hazard summary： 一种刺激物，可能造成严重眼损伤；经口有害；[Sigma-Aldrich MSDS] 参见多溴联苯。
- reactive group： 芳基卤化物
- First aid measures： 食入：不要催吐。如果受害者意识清醒且没有抽搐，给予1-2杯水稀释化学物质，并立即呼叫医院或中毒控制中心。如果医生建议，准备将受害者送往医院。如果受害者抽搐或昏迷，不要经口给予任何东西，确保受害者的气道通畅，让受害者侧卧，头部低于身体。不要催吐。立即将受害者送往医院。(NTP, 1992)
- exposure pathway： 口服 (L628); 吸入 (L628); 经皮 (L628)
- Toxicity summary： PBBs的毒性确切机制因具体同系物而异。据信，主要的相互作用涉及芳基烃受体（AhR）。PBBs与AhR结合并激活它，进而启动一系列基因的转录上调，影响生化与内分泌途径、细胞周期调控、形态发生、氧化应激反应以及其他各种过程。这导致了PBBs的多种毒性反应特征。一些已知的诱导基因包括细胞色素P-450依赖性单加氧酶CYP1A1和CYP1A2。(L628)
- Regulatory information： REACH限制物质：限制条件文件：PDF链接
- fire hazard： 该化学品可燃。(NTP, 1992)
- fire fighting： 涉及此材料的火灾应使用干化学灭火器、二氧化碳或哈龙灭火器进行控制。(NTP, 1992)
- Health Effects： PBB暴露可能导致体重减轻、皮肤疾病（如痤疮）、神经和免疫系统影响，以及对肝脏、肾脏和甲状腺的影响。(L628)
- reactivity profile： 4-溴联苯可能对光敏感。该化合物可与氧化剂反应。(NTP, 1992)
- Symptoms and Signs： PBB暴露的症状可能包括恶心、腹痛、食欲不振、关节痛、疲劳和虚弱。(L629)
- 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)
- Minimum Risk Level： 急性经口：0.01 mg/kg/天 (L134)
- Air and water reaction： 不溶于水。
- Hazard categories and classifications： 水生急性1 (86%)
- Non-fire leakage response： 储存注意事项：应保护此材料免受光照，并将其存放在冰箱中。(NTP, 1992)
- Personal protective equipment (PPE)： 推荐呼吸器：在称量和稀释纯测试化学品时，佩戴NIOSH批准的半面罩呼吸器，配备有机蒸气/酸性气体 cartridges(专门用于有机蒸气、HCl、酸性气体和SO2)和粉尘/雾过滤器。(NTP，1992)
- Carcinogen Classification： 2A，可能对人类致癌。(L135)
