Foam Deluge Fire Suppression

Mainly used on large applications where water or gas cannot be used. These tend to be external such as transformers, oil tanks and oil storage silo’s.

A simple sprinkler open deluge type application with the heads (usually open) spread around the risk, a foam concentrate is mixed with the water to provide the typical expanding agent (the same as with extinguishers).

Will need a large amount of fabrication work to support the pipe work, valves and heads to and around the risk.

Advantages

• Good for external areas.
• Covers large areas.
• Protects flammables liquids – airports, aircraft hangers, oil storage.

Disadvantages

• Wet agent so electrical risk needs to be considered.
• Messy – clean up required.
• Same disadvantages as sprinklers for water and pump supplies, although because of the expanding effects of foam this sometimes means not as much water is required.

Applications

• Machine Spaces
• Tunnels
• Switch rooms
• Transportation
• Generators (Local app)
• Fuel Stores
• Aircraft Hangars
• Storage silos
• Machines/process that are outdoors
