Chemguard ECOGUARD is a specially formulated, synthetic fluorine free fire-fighting foam concentrate based on an innovative patented polymer surfactant, low-toxicity hydrocarbon surfactants, and other non-hazardous ingredients. As a result, it is substantially biodegradable and presents the lowest environmental impact of any UL listed Class B fire-fighting foam.

As an AFFF and Fluoroprotein foam alternative, this advanced formulation produces similar fire-fighting performance as AFFF and Fluoroprotein products while containing no organofluorine components. When used in systems and handline applications, ECOGUARD produces a strong and cohesive foam blanket on the surface of the fuel to extinguish fire and suppress fuel vapor.

ECOGUARD is intended for use at a proportioning rate of 3% for top-side / handline applications and select sprinkler applications on Class B hydrocarbon type fuels such as gasoline, kerosene, diesel, etc. It is also intended for use a proportioning rate of 6% for various other sprinkler applications.

ECOGUARD is to be used on hydrocarbon fuels only.

  • Chemguard ECOGUARD is designed for use with the following types of foam proportioning equipment.
  • In-line balanced pressure and pump pressure-proportioning skid.
  • Bladder tank balanced pressure-proportioning systems.
  • Around the pump proportioning equipment.
  • Handline, air-aspirating nozzles with fixed eductor pickup tube.
  • Fixed or portable in-line eductors.
  • ECOGUARD is not designed for premix applications.


  • Air-aspirating and various non air-aspirating sprinkler heads or spray nozzles.
  • Foam Chambers.
  • Air-aspirating foam nozzles.
  • Foam makers for use with either Floating Roof storage tanks or Dike/Bund protection systems.


  • Storage tanks (hydrocarbon fuels only)

  • Mobile equipment


Chemguard ECOGUARD is designed to perform as a “Synthetic Foam Concentrate” as defined by UL 162. It is listed for multiple applications, including topside, handline, and sprinklers.


Aspirating type discharge devices typically generate expansion ratios between 6-10:1 when mixed with water at the correct mix ratio. Expansion ratios are dictated by the type of discharge devices, flow rate and discharge pressure.
