What color and shape represents combustible metals in the fire classification system?

  1. Yellow Star (D)

  2. Blue Circle (C)

  3. Green Triangle (A)

  4. Red Square (B)

The correct answer is: Yellow Star (D)

The classification of combustible metals in the fire system is represented by a yellow star symbol. This specific visual cue is used to identify the unique hazards associated with metals susceptible to combustion, such as magnesium, titanium, and sodium, among others. These metals require particular handling and extinguishing methods due to the distinct nature of their fires, which often cannot be effectively fought with conventional fire extinguishers. The star shape is important as it differentiates this category from others in a straightforward manner, enabling quick recognition during emergencies. The bright yellow color further reinforces the warning, as it is universally associated with caution. This system allows for rapid identification of the potential risks in a fire scenario involving combustible metals, ensuring that responders take appropriate precautions and measures.
