What potential consequence arises from improper firestop installation?

Improper firestop installation can lead to compromised building safety, which is critical in maintaining a structure's integrity during a fire. Firestops are designed to prevent the spread of smoke and flames through penetrations in fire-resistance-rated walls and floors. When installed incorrectly, these systems may fail to contain a fire, allowing it to spread beyond the original location, endangering lives and property.

The importance of firestop systems lies in their ability to protect escape routes and limit damage. If these systems are not properly installed, it can undermine the entire purpose of fire-resistance-rated barriers, thus jeopardizing the safety of occupants and first responders. The other options do not directly relate to the primary function of firestops, making them less relevant in this context. For example, while proper installation could enhance insulation or ventilation indirectly, the critical focus should be on safety, which makes compromised building safety the most significant consequence.
