Cabinets with portable fire extinguishers shall be marked with the words 'Fire Extinguisher' in letters at least ______ inches high.

• A. 1 inch
• B. 3 inches
• C. 2 inches
• D. 4 inches

Answer: (C)

The main point is readability of signage for quick identification. Cabinets that hold portable fire extinguishers need to be clearly labeled so someone can spot the label fast in an emergency. The standard sets a minimum letter height of two inches for the words “Fire Extinguisher.” This height strikes a practical balance between legibility from a reasonable distance and fitting on the cabinet. Letters smaller than that, like one inch, are hard to read quickly, especially in smoky or low-light conditions. Larger heights, such as three or four inches, would still be readable but aren’t required by the rule; the requirement is at least two inches.
