Cover the irritated skin with an emollient. Seek medical attention. Treat symptomatically and supportively. Wash any contaminated clothing before reusing. Inhalation If the victim is not breathing, perform artificial respiration. Loosen tight clothing such as a collar, tie, belt or waistband. If breathing is difficult, oxygen can be administered. Seek medical attention. Treat symptomatically and supportively. Ingestion INDUCE VOMITING by sticking finger in throat. Lower the head so that the vomit will not reenter the mouth and throat. Loosen tight clothing such as a collar, tie, belt, or waistband. If the victim is not breathing, administer artificial respiration. Examine the lips and mouth to ascertain whether the tissues are damaged, a possible indication that the toxic material was ingested; the absence of such signs, however, is not conclusive. Seek immediate medical attention and, if possible, show the chemical label. Treat symptomatically and supportively. Section V. Fire and Explosion Data Flammability Combustible.

Instructions In case of a spill and/or a leak, always shut off any sources of ignition, ventilate the area, and exercise caution. Use a shovel to put the material into a convenient waste disposal container. Finish cleaning the spill by rinsing any contaminated surfaces with copious amounts of water. Consult federal, state, and/or local authorities for assistance on disposal. Section VII. Handling and Storage Handling and Storage IRRITANT. Keep away from heat and sources of ignition. Mechanical exhaust required. When not in use, tightly seal the Information container and store in a dry, cool place. Avoid excessive heat and light. DO NOT ingest. DO NOT breathe dust. In case of insufficient ventilation, wear suitable respiratory equipment. If ingested, seek medical advice immediately and show the container or the label. Treat symptomatically and supportively. Avoid contact with skin and eyes. Always store away from incompatible compounds such as oxidizing agents. Section VIII. Exposure Controls/Personal Protection Engineering Controls Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit. Personal Protection Splash goggles. Lab coat. Dust respirator. Boots. Gloves. A MSHA/NIOSH approved respirator must be used to avoid inhalation of the product.

H0363 Hexabromobenzene Page 3 Section XII. Ecological Information Ecotoxicity Not available. Environmental Fate Hexabromobenzene's possible production and use as a flame retardant may result in its release to the environment through various waste streams. Hexabromobenzene may also enter the environmentas a result of the high temperature breakdown of other brominated fire retardants. If released to the atmosphere, hexabromobenzene will exist solely in the particulate phase in the ambient atmosphere, based on an estimated vapor pressure of 1.6X10-8 mm Hgat 25 deg C. Particulate-phase hexabromobenzene may be physically removed from the air by dry deposition. An estimated Koc value of 48,000 suggests that hexabromobenzene will be immobile in soil. Volatilization from moist soil surfaces may occur based on an estimated Henry's Law constant of 2.8X10-5 atm-cu m/mole. Volatilization from dry soil surfaces is not expected given the vapor pressure of this compound. Based on limited data, hexabromobenzene is expected to be resistant to microbial degradation in both soil and aquatic environments; 8 and 10% biodegradation was reported for river water and sea water, respectively, after a 3 day incubation. In water, hexabromobenzene should adsorb to sediment or particulate matter based on its Koc value. This compound may volatilize from water surfaces given its estimated Henry's Law constant. Estimated half-lives for a model river and model lake are 3 and 32 days, respectively, although adsorption to sediment and particulate matter may attenuate this process. The volatilization half-life from a model pond, taking into account adsorptive processes, is 114 months. Information on the bioaccumulation of hexabromobenzene in fish is conflicting with biocentration potential ranges from low to very high. In short-term studies, hexabromobenzene was non-accumulative in fish. However, in a 96 day study using rainbow trout, a mean BCF value of 1,100 was measured. It was suggested that non-accumulation was due to the size of hexabromobenzene, resulting in a lack of membrane permeation. Occupational exposure to hexabromobenzene may occur by dermal contact or respiratory routes during its production
