| Reaktive Gruppe | Aryl Halides |
| Reactivity Profile | 4-BROMOBIPHENYL may be sensitive to light. This compound can react with oxidizing materials. (NTP, 1992) |
| Air and Water Reactions | Insoluble in water. |
| Hazard Classes and Categories | Acute Tox. 4 (92%) |
| Brandbekämpfung | Fires involving this material should be controlled using a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992) |
| Erste Hilfe | EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. |
| Freisetung ohne Brand | SMALL SPILLS AND LEAKAGE: Should a spill occur while you are handling this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with ethanol and transfer the dampened material to a suitable container. Use absorbent paper dampened with ethanol to pick up any remaining material. Seal the absorbent paper, and any of your clothes, which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with ethanol followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned. |
| Isolation and Evacuation | Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: |
| Minimum Risk Level | Acute Oral: 0.01 mg/kg/day (L134) |
| Personal Protective Equipment (PPE) | RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992) |
| 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. |
| Gesundheitliche Auswirkungen | PBB exposure may cause weight loss, skin disorders (such as acne), nervous and immune systems effects, and effects on the liver, kidneys, and thyroid gland. (L628) |
| Expositionspfade | Oral (L628)inhalation (L628)dermal (L628) |
| Toxizitätsübersicht | The exact mechanism of toxicty of PBBs varies depending on the specific congener. The predominant interaction is believed to involve the aryl hydrocarbon receptor (AhR). PBBs bind to and activate the AhR, which in turn initiates the transcriptional upregulation of a number of genes, affecting biochemical and endocrine pathways, cell cycle regulation, morphogenesis, oxidative stress response, and various other processes. This results in the numerous toxic responses characteristic of PBBs. Some of the known induced genes include the cytochrome P-450-dependent monooxygenases CYP1A1 and CYP1A2. (L628) |
| Signs and Symptoms | Symptoms of PBB exposure may include nausea, abdominal pain, loss of appetite, joint pain, fatigue, and weakness. (L629) |
| Carcinogen Classification | 2A, probably carcinogenic to humans. (L135) |
