Which statement correctly describes the cabinet marking requirement for extinguishers?

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

Answer: (D)

Clear and quick identification of an extinguisher cabinet is the goal. The marking on the cabinet needs to be large enough to read at a glance in an emergency, from a reasonable distance and under stress or dim lighting. A two-inch letter height provides that practical visibility without crowding the cabinet door. Smaller markings, like one inch, can be hard to read quickly, while much larger markings (three or four inches) aren’t usually required and may not fit on standard cabinet doors. So the standard that achieves reliable readability and practical fit is two inches.
