Under what condition can SFRM be applied to primed or painted surfaces?

• A. When specifically allowed in the design criteria.
• B. When the temperature is below 50 degrees Fahrenheit.
• C. When the surface is textured.
• D. When the coating is non-toxic.

Answer: (A)

SFRM, or Spray-applied Fire-resistive Material, can only be applied to primed or painted surfaces when it is specifically allowed in the design criteria. This is crucial because the design criteria take into account factors like adhesion, fire resistance, and compatibility of the materials. If the design criteria do not permit SFRM application over such surfaces, it may lead to inadequate fire protection and compromise safety. Using SFRM without adhering to the design guidelines can result in failure of the SFRM to adhere properly, potentially leading to its detachment during a fire event, which would not provide the intended fire protection. Therefore, the specifications outlined in the design criteria are essential for ensuring effectiveness and compliance with safety standards.
