• B. 4 inches
• C. 6 inches
• D. 8 inches

Answer: (B)

The minimum height for 'No Smoking' signs near fueling areas, as specified by NFPA 407, is set at 4 inches. This standard is crucial for ensuring that the signs are visible and easily legible to everyone in the vicinity, particularly in high-traffic and potentially hazardous environments like fueling areas at airports. These signs serve to communicate safety protocols effectively, helping to mitigate the risk of fire hazards associated with smoking in areas where flammable materials are present.

Maintaining a uniform height for these signs ensures consistency and compliance across different airport facilities, thereby enhancing overall safety measures. Proper signage can significantly contribute to the awareness and behavior of personnel and the public, reminding them of the critical dangers associated with smoking near fuels.
