What is the primary purpose of a deluge sprinkler system in a fire emergency?

The primary purpose of a deluge sprinkler system is to wet down an entire area. This system is specifically designed for high-hazard environments where rapid fire growth is a concern, such as in warehouses or industrial facilities storing flammable materials. Unlike conventional sprinkler systems that activate individually in response to heat, a deluge system has open nozzles that are activated simultaneously by a fire alarm or detection system, releasing a large volume of water across a wide area. This immediate and extensive water coverage helps in preventing the spread of fire and minimizes damage.

The focus on soaking the entire area helps to control the fire's potential growth and can also assist in cooling down any combustible materials that may not be directly ignited yet. This makes deluge systems particularly effective in managing fires that could escalate quickly if not rapidly addressed.
