Florida Building Code Practice Exam

Which label element is NOT required for fire-retardant-treated lumber and wood structural panels?

1. Identification of the treating manufacturer

2. Location of treatment facility

3. Flame spread index

4. Type of fire-retardant treatment

The correct answer is: Location of treatment facility

The label element that is not required for fire-retardant-treated lumber and wood structural panels is the location of the treatment facility. While the identification of the treating manufacturer, the flame spread index, and the type of fire-retardant treatment are specified requirements to ensure the proper performance and identification of treated materials, the actual location where the treatment took place is not mandated to be included on the labels. In context, the purpose of the label's requirements is to provide crucial information regarding the quality and characteristics of the treated materials, which aid in ensuring compliance with safety standards. Knowing the manufacturer allows for accountability, the flame spread index informs builders and inspectors about the product's fire behavior, and specifying the type of treatment ensures that the lumber or panels have been processed with an appropriate and effective fire-retardant method. However, knowing where the treatment facility is located does not directly contribute to the performance or safety of the material, making it unnecessary as a labeling requirement.
