In the context of SFRM, what would be done if the installation does not fill the voids adequately?

The correct action in the context of Spray-Applied Fire-Resistive Material (SFRM) is to fill the voids. Adequate filling of voids is crucial to ensure the intended fire-resistance rating is achieved. Voids can compromise the performance of the fireproofing system, leading to reduced effectiveness during a fire event. Therefore, if the installation does not adequately fill the voids, it is essential to rectify this by filling the voids with the appropriate fireproofing material.

Filling the voids helps to ensure a continuous layer of protection, which is vital for maintaining the structural integrity of the building and maximizing safety. This action aligns with industry standards and best practices, which emphasize thorough application of fireproofing materials to provide a reliable barrier against heat and flames.

While other options may seem like they address the situation, they do not ensure compliance with safety requirements or performance standards like filling the voids does. Leaving it incomplete or documenting the issue do not provide the necessary fire protection. Installing additional layers may not be effective if the existing layer is not adequately applied to begin with; hence, the primary focus should be on correcting the inadequate installation first.
