• A. Increased durability
• B. Clear visibility for personnel
• C. Lower costs in production
• D. Compliance with aesthetics

Answer: (B)

A height of 4 inches for emergency signage is particularly important for ensuring clear visibility for personnel. Signage used in emergencies must be able to be seen and understood quickly, even from a distance or in stressful conditions. The size of the text, measured in inches, plays a crucial role in making sure that it is legible.

When emergency situations arise, individuals may be under duress or may need to process information rapidly. A height of 4 inches is generally considered a standard that allows the text to be read easily while maintaining visibility across substantial distances. This helps ensure that critical information regarding evacuation routes, safety equipment, or emergency protocols can be clearly understood by all personnel, including those who may not be familiar with the area.

Additionally, other factors such as color contrast, font style, and background can also contribute to visibility, but the text height itself is foundational in making sure that the signage can capture attention quickly and effectively.
