What is the required minimum size of the letters used in labeling a damper access panel as "smoke damper" according to NFPA?

• A. 1/4" height
• B. 1/2" height
• C. 3/4" height
• D. 1" height

Answer: (B)

The minimum size of the letters used in labeling a damper access panel as "smoke damper" according to NFPA standards is specified to be 1/2 inch in height. This requirement is established to ensure that the labeling is clearly visible and legible, allowing quick identification during emergency situations or routine inspections. Having a standardized letter height helps maintain consistency across various installations, making it easier for personnel to locate and recognize smoke dampers within an HVAC system. This is particularly important in fire safety scenarios, where rapid access to equipment can impact firefighting efforts and ensure the system operates as intended. Therefore, the 1/2 inch height serves both safety and operational efficiency purposes within the guidelines set by NFPA standards.
