BIS(PENTABROMOPHENYL) ETHER ICSC: 1689 Decabromodiphenyl ether Decabromo biphenyl oxide Decabromo phenoxybenzene Benzene 1,1' oxybis-, decabromo derivative DBDPE DBDPO DBBE DBBO C12 Br10O Molecular mass: 959.2 ICSC #    1689 CAS #     1163-19-5 RTECS # KN3525000 Types of Hazard/ Exposure Acute Hazards/ Symptoms Prevention First Aid/ Fire Fighting FIRE Not combustible. In case of fire in the surroundings: use appropriate extinguishing media. Explosion Exposure  •Inhalation Ventilation. Fresh air, rest.  •Skin Protective gloves. Rinse and then wash skin with water and soap.  •Eyes Safety spectacles. Rinse with plenty of water (remove contact lenses if easily possible).  •Ingestion Do not eat, drink, or smoke during work. Rinse mouth. Give one or two glasses of water to drink. Spillage Disposal Storage Packaging & Labelling Personal protection: particulate filter adapted to the airborne concentration of the substance. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Separated from food and feedstuffs Signal: Danger Health haz Causes damage to thyroid through prolonged or repeated exposure BIS(PENTABROMOPHENYL) ETHER ICSC: 1689 Important Data Physical State; Appearance: WHITE CRYSTALLINE POWDER Physical Dangers: Chemical Dangers: On combustion, forms toxic fumes. Occupational Exposure Limits: TLV not established. MAK not established. Routes of Exposure: Inhalation Risk: A nuisance-causing concentration of airborne particles can be reached quickly. Effects of Short-Term Exposure: Effects of Long-Term or Repeated Exposure: The substance may have effects on the thyroid brominated PBDEs can also cause thyroid hormone imbalance. Deca-BDE significantly increased the incidence of thyroid hyperplasia and tumors among male and female mice in a two-year feeding study Physical Properties Melting point: 300-310°C (See Notes) Relative density (water = 1): 3.0 Solubility in water: none Vapour pressure, Pa at 21°C: negligible Octanol/water partition coefficient as log Pow: 6.27 Environmental Data Environmental effects from the substance have not been investigated adequately. N O T E S The substance has a variable melting and boiling range, reflecting the nature of the material and the individual manufacturing processes.
