What is the smoke color for a Class Bravo fire?

The smoke color for a Class Bravo fire is black or brown. Class Bravo fires involve flammable liquids such as gasoline, oil, and grease, which produce thick, black smoke when burned. This black smoke is primarily due to the incomplete combustion of hydrocarbons found in these fuels, indicating a high carbon content.

The characteristic color of the smoke provides critical information about the nature of the fire. Black smoke, for example, can signal that the fire includes heavy fuels, and it often indicates greater danger due to the volatile nature of the burning materials. Recognizing the type of smoke generated during a fire can help responders take appropriate action, including determining the best firefighting methods and personal protective equipment needed. Understanding these characteristics is essential for effective firefighting and safety measures in maritime operations.

Other colors listed, such as white or grey, are typically associated with different types of fires or materials burning. Green and red do not represent any known fire classification and are not applicable in this context.
