Trainol 3

3% Fluorine Free Training Foam Concentrate (TF)

A fluorosurfactant free training foam which mimics the application and physical properties of Angus TridolC6 S AFFF 3% fire fighting foam.

Trainol 3 is a Fluorine-Free Foam (F3) concentrate for 3% usage, which has been specially formulated to provide a unique training foam with a synthetic base material but no fluorosurfactants. 

Trainol 3 mimics the performance of Angus TridolC6 S 3 AFFF, the aviation industry standard for fire fighting foams, to provide realistic fire training without the use of fluorinated chemicals. 

With almost identical induction characteristics to Angus TridolC6 S 3 AFFF, Trainol 3 is the first foam which can be used routinely as a substitute for vehicle and equipment testing, while complying with Civil Aviation and Environment Agency regulatory requirements.

Trainol 3 was developed to meet the stringent environmental and regulatory requirements of the aviation sector, but this does not limit its use to aviation. Trainol 3 has clear training benefits for other fire fighting applications like offshore drilling and production platforms.

  • Low toxicity
  • Mimics the performance of Angus TridolC6 S 3 AFFF
  • Can be used routinely as a substitute for vehicle and equipment testing

Performance Approvals 

Trainol 3 was developed to meet the stringent environmental and regulatory requirements of the aviation sector, but this does not limit its use to aviation. Trainol 3 has clear training benefits for other fire fighting applications like offshore drilling and production platforms.

Environmental Impact       

Trainol 3 is formulated for minimum environmental impact. It is produced from synthetic detergent, and is free of fluorinated chemicals, and glycol ethers. It is also readily biodegradable.


Trainol 3 should be used in training through conventional foam induction and delivery equipment (such as the Angus Hi-Combat range of portable foam equipment). It is not recommended for real life fire fighting incidents.   


3% induction is recommended to simulate induction and foam quality performance of TridolC6 S 3.
