Bromine MSDS

What is Bromine?

Bromine is a homogeneous halogen which is an inorganic non-metal compound in which the largest atom is a noble gas. Bromine is non-carcinogenic but toxic. Bromine is a red-brown liquid at room temperature that evaporates to form a similarly colored gas. Bromine has a sharp, unpleasant odor. Bromine compounds are used in well drilling fluids, photographic film, and as an intermediate in organic chemistry. Bromine is also used in flame retardants.

Bromine Exposures and Health Risks

Since Bromine readily evaporates at standard pressure, it is commonly present in liquid and gas phases. This allows for inhalation, ingestion, and skin/eye contact. Bromine inhalation will cause dizziness, headaches, as well as lacrimation (crying), coughing, and nosebleeds. Ingestion can cause abdominal pain and diarrhea. Direct contact can cause measles-like eruptions and burns to the skin or eye. Large amounts of bromine are toxic and cause bromism, a disease that has neurological, psychiatric, gastrointestinal, and dermatological effects. Should skin contact occur, wash immediately with soap and water and remove contaminated clothing. Should inhalation occur, remove to fresh air and provide oxygen support if necessary. If bromine is ingested, contact medical assistance immediately.

Measuring Bromine

Bromine can be measured in air or in water (dissolved) in units of parts per million (ppm). We carry portable, fixed, and dissolved bromine monitors, and all of our bromine monitors can be viewed HERE.
