A Finnish solution for wildfire suppression worldwide
Controlling forest fires with a safe and sustainable solution
PPO® ForExt (Forest Fire Extinguishing Agent) is a Finnish wildfire suppression agent developed by PPO-Elektroniikka Oy
and manufactured by Kiilto Oy. It is fluorine-, halogen-, and heavy-metal-free, and designed for effective wildfire suppression,
fire containment, and mop-up operations in demanding wildland conditions.
ForExt is used as a water additive and applied using all existing firefighting equipment. It improves cooling, increases adhesion to
vegetation and ground surfaces, and helps prevent fire spread and re-ignition.
Its performance has been demonstrated in multiple tests and real-world wildfire scenarios in Finland and internationally.
Safety documentation and materials
PPO® ForExt has been evaluated in accordance with EU chemical legislation (CLP Regulation (EC) No 1272/2008).
When used as directed, it is not classified as hazardous to humans or the environment and does not require hazard labelling
under the Globally Harmonised System (GHS).
ForExt is designed to support effective wildfire suppression with a strong focus on environmental and operational safety.

The video shows PPO® ForExt used in real-world wildfire suppression and demonstration environments. It highlights how ForExt
supports fire containment, active suppression and mop-up operations when applied with existing firefighting equipment.
Use cases for PPO® ForExt
Professional firefighting
Wildland firefighting is highly demanding, often involving difficult terrain, limited access and long operational periods. PPO® ForExt
is designed to support professional wildfire suppression by improving fire containment, cooling and re-ignition control.
Protection of property and surroundings
Wildfires increasingly threaten homes, infrastructure and communities worldwide. PPO® ForExt can be used to provide short-term preventive protection in selected areas, helping protect properties, courtyards, and surrounding vegetation when a wildfire approaches.
Hot work and controlled use
Hot work generates heat, sparks and open flames that can pose a fire risk in dry conditions. When mixed with water and applied to surrounding areas, PPO® ForExt helps reduce the risk of ignition and fire spread. It can also be used to support safe extinguishment after controlled fire use.
PPO® ForExt supports wildfire containment
- Reduces flame intensity and fire progression
- Supports effective fire containment
- Improves cooling and suppresses residual heat
- Helps prevent re-ignition
- Mixed with water at low ratios (typically 1:100)
- Compatible with all existing firefighting equipment
PPO® ForExt is a sustainable wildfire suppression solution
- Fluorine-free, halogen-free and free of heavy metals
- Assessed as safe for people, nature and equipment
- Supports firefighters by reducing heat and smoke exposure
- Helps protect surrounding forests and natural habitats
- Reduces wildfire-related damage to land and assets

PPO® ForExt in action
Test case: Hay fire extinguishing test with the PPO® ForExt
In this video, we will demonstrate, using dry hay, how the forest fire extinguishing agent PPO® ForExt works.
Before we lit the fire, we treated the right side of the hay with the ForExt-water mixture (1:100). The left side was left untreated. We ignited both sides with a burning object. The left side burned completely, but the fire did not spread to the area treated with ForExt.
Test case: Extinguishing a forest fire with PPO® ForExt/ Niinisalo, Finland
We tested the functionality of the PPO® ForExt at the Niinisalo garrison in Finland. Thanks to the teams of the Rescue Services of Satakunta and the Pori Brigade.
Half of the area was treated with pure water and half with ForExt/water mixture 1:100. The weather was dry and hot; it hadn’t rained in a few weeks. We waited half an hour before lighting the fire. The water had evaporated, so the fire advanced at full speed in the water-treated area. When the fire reached the area treated with the ForExt/water mixture, it was immediately extinguished.
