A 60-B fire extinguisher is designed to extinguish fires involving flammable liquids, and its rating signifies that it has the ability to handle a larger fire compared to extinguishers with lower ratings, such as the 1-B extinguisher. The numerical value following the letter 'B' indicates the extinguisher's capacity in terms of the amount of fuel it can effectively extinguish, with higher numbers representing greater effectiveness.

In this context, the rating indicates that a 60-B extinguisher can extinguish a fire that is significantly larger than that tackled by a 1-B extinguisher. Specifically, it indicates that the 60-B extinguisher can handle fires that are equal to 60 times the size of those manageable by a 1-B unit. Understanding this scale helps firefighters and safety personnel determine the appropriate extinguisher needed based on the type and volume of potential fire hazards they may encounter.

Knowing how to select the right extinguisher based on its rating is crucial for safety and effective fire response, especially when dealing with different classes of fire.
