What is referred to as a poke through in building safety?

In building safety, a "poke through" specifically refers to a penetration through the floor. This term is particularly relevant in the context of fire safety and building codes, as it pertains to the means through which electrical, plumbing, or communication systems may pass from one floor to another. When a poke through occurs, it introduces considerations for fire stopping, as penetrations can create pathways that allow the spread of smoke and fire between levels. Proper sealing and fire-rated materials are crucial in managing these penetrations to maintain the integrity of the building's fire-resistive features. Understanding the implications of poke throughs is vital for safety inspections, as they can affect escape routes and fire containment within multi-story buildings.
