In which scenario is firestop putty typically utilized?

Firestop putty is specifically designed to provide fire resistance in applications that involve electrical conduits or cable penetrations. When cables and conduits pass through fire-rated walls or floors, it is essential to maintain the fire barrier integrity. Firestop putty helps to seal these openings, preventing the spread of fire, smoke, and hot gases through the penetrations.

Using firestop putty around electrical conduits or cable penetrations is crucial because these penetrations often create pathways that could compromise the effectiveness of fire-rated assemblies. Firestop putty expands when exposed to heat, filling gaps and cracks around these conduits to ensure that the firewall remains intact in the event of a fire. This not only enhances safety but also complies with building codes and standards designed to protect occupants and property.

In contrast, sealing around duct penetrations, filling cracks in non-fire-rated walls, and waterproofing bathroom installations do not align with the primary intended use of firestop putty. Other materials are more appropriate for those specific scenarios, making the selection of firestop putty more targeted and effective for maintaining fire safety standards.
