How does an unsealed void affect a building's safety?

An unsealed void poses a significant threat to a building's safety as it can allow for the spread of fire and smoke. When a fire occurs, the presence of unsealed voids provides pathways for heat, flames, and toxic smoke to travel rapidly throughout a structure. This can lead to increased danger for occupants and hinder evacuation efforts.

Additionally, unsealed voids can compromise the effectiveness of fire barriers and firestop systems designed to contain fires within specific areas. These firestopping measures are crucial for limiting fire spread and providing additional time for occupants to escape and for emergency services to respond. Hence, sealing voids properly is vital in maintaining fire safety standards and protecting the overall integrity of the building in emergency situations.
