External Sprinklers: A Viable Defense Against Wildfires in Fire-Prone Areas

The recent wildfires in the Malibu area have sparked discussions on effective ways to protect residences from fire damage. One solution suggested by our office was the installation of an external sprinkler system. While these systems may not offer full protection, they can provide crucial time for evacuation and mitigate the risk of a property catching fire.

Overview of External Sprinkler Systems

During a wildfire, the primary goal is to prevent ember and ash from igniting flammable materials around a home. While traditional sprinklers are effective in controlling indoor fires, their application in combating wildfires needs to be reconsidered given the nature of the threat. However, external sprinklers can be set up to soak the exterior of a house, including sloped surfaces, windows, and doors, to prevent the fire from spreading.

Benefits and Limitations of External Sprinklers

These systems can be highly effective during a wildfire, particularly in areas with limited vegetation around structures. If properly installed, external sprinklers can help protect against embers and sparks that can land on a house and ignite flammable materials. Moreover, these sprinklers can be designed to provide a deluge of water, ensuring that all critical areas are adequately covered.

While external sprinklers can offer several advantages, they also come with certain limitations. For instance, the system requires a reliable emergency water supply and a backup power source to operate effectively. Additionally, it is essential to clear burnable materials away from the house and use non-flammable roof and siding materials to further reduce the risk of fire.

Case Studies from Other Regions

The safety measures employed in regions prone to wildfires, such as Australia, serve as a compelling example of the potential benefits of external sprinklers. In Australia, homes are often equipped with external sprinklers specifically for fire protection. These systems are designed to withstand the intense conditions of a bushfire, providing a barrier by soaking the exterior of the house and surrounding areas.

Interestingly, in the Malibu area, despite its lack of forests, there is still scrubland that can serve as fuel for a wildfire. Therefore, even if the area lacks a traditional forest, the presence of these flammable materials around structures can make external sprinklers a valuable tool in wildfire prevention.

Conclusion

In conclusion, while external sprinklers may not offer complete protection against wildfires, they can provide a layer of defense that can save valuable time during an evacuation. By soaking the exterior of a home and providing a deluge of water, these systems can significantly reduce the risk of a property catching fire, especially in areas with flammable materials surrounding structures.

For homeowners in fire-prone areas, considering the installation of external sprinklers as part of a comprehensive wildfire protection plan can be highly beneficial. However, it is crucial to ensure that the system is properly installed and maintained, with reliable backups for both water supply and power in case of emergencies.
