What is one of the primary results you should look for after extinguishing a Type B fire?

One of the primary results to look for after extinguishing a Type B fire is the absence of visible signs of smoke. This is important because smoke can indicate that there are still materials smoldering or that the fire has not been fully extinguished. For Type B fires, which involve flammable liquids such as oils, gasoline, and solvents, any remaining smoke may suggest that there are still vapors present, increasing the risk of reignition. Ensuring that there are no visible signs of smoke means that the fire is likely fully out, demonstrating effective extinguishing and minimizing further hazards.

In contrast, the presence of water residues is not typically a concern with Type B fires, which require the use of dry chemical extinguishers or foam. Minimal debris may not adequately reflect whether a fire has been completely extinguished. Lastly, while checking for the cool temperature of nearby surfaces is essential, it may not alone indicate that all flames and smoke have been eliminated. Thus, verifying for the absence of smoke provides a clear indication that fire control measures were successful.
