Which of the following represents a light hazard for Class A?

The classification system for Class A hazards is determined by the fire rating assigned to extinguishers, which reflects their effectiveness against fire risks involving ordinary combustibles such as wood, paper, and textiles. In this system, the number prefix signifies the size of the fire the extinguisher can effectively combat—higher numbers indicate a larger capacity to handle respective fire incidents.

A rating of 2-A is particularly significant, indicating a moderate level of effectiveness in extinguishing small to medium-sized fires. Class A issues typically depend on the combustibility of materials, and the 2-A rating effectively indicates that the extinguisher can handle just over two cubic feet of ordinary combustibles.

Therefore, a light hazard in a Class A context aligns with a rating that indicates the ability to manage relatively minor fire hazards, making the 2-A rating the appropriate choice. In contrast, other choices such as the cubic footage values do not represent fire classifications but rather physical dimensions that do not correlate with extinguishing capacity or fire hazard assessments.
