If breathing is difficult, give oxygen. In case of contact, immediately flush skin or eyes with plenty of water for at least 15 minutes. In all cases call a physician. Not combustible, but substance is a strong oxidizer and its heat of reaction with reducing agents or combustibles may cause ignition. Highly toxic and dense fumes are emitted when bromine is heated.
Vapors can flow along surfaces to low lying areas.
Use any means suitable for extinguishing surrounding fire. Water spray may be used to keep fire exposed containers cool. Stable under ordinary conditions of use and storage. Emits fumes of Bromine and Bromides upon thermal decomposition. Hydrogen Bromide is a by-product of many bromine reactions.
