What type of smoke is typically associated with Bravo fires?

Bravo fires are classed as fires involving flammable liquids, such as gasoline, oil, or grease. When these materials combust, they typically produce black smoke. This is significant because the black smoke is indicative of the incomplete combustion of these hydrocarbons, which often occurs in class B fires. The dense black smoke can be a crucial warning sign during firefighting efforts, indicating not only the presence of flammable liquids but also that there may be toxic gases that could pose further risks to firefighters and surrounding individuals. Understanding the characteristics of the smoke generated can help responders prepare and protect themselves adequately while combating the fire.
