According to IBC regulations, where must a sign or stencil identifying a firewall be located?

The correct choice reflects the International Building Code (IBC) regulations that specify the placement of signs or stencils identifying firewalls. By stating that these markers must be positioned within a distance of 15 to 30 feet from the wall and at intervals not exceeding 30 feet, it ensures that individuals can quickly and easily identify the presence of a firewall, which plays a crucial role in fire safety and containment in a building.

This specific distance allows for adequate visibility and provides a clear guideline for placement, enhancing awareness of fire safety protocols among occupants and first responders. The requirement for intervals not exceeding 30 feet further reinforces accessibility to the information, helping to maintain a consistent understanding of the layout of fire-rated areas throughout the premises.

Additionally, the other options do not align with IBC guidelines regarding distance and intervals for signage. They either suggest placements that are too close or too far from the wall or do not specify the requirement for intervals adequately, thus not adhering to the compliance needed for effective fire safety measures.
