=Potential Hazards=

• BME has a very low odor threshold (0.12-0.64 ppm) and smells similar to the odorant used in natural gas. If the odor becomes widespread, people in nearby areas may suspect a natural gas leak. This can lead to calls to the fire department and/or evacuation of the building, which can be inconvenient and disruptive.

• BME can be toxic if ingested and fatal if inhaled or absorbed through the skin.

• Vapors can irritate the eyes, mucous membranes, and respiratory tract. Symptoms of inhalation exposure may include coughing, sore throat, and/or shortness of breath.

• When BME is heated to decomposition, toxic fumes including sulfur oxides and carbon oxides will be emitted.

• BME is combustible as a liquid or vapor.

• Reactions of BME with strong acids or alkali metals will release flammable hydrogen gas.
