There are only 3 known "methods" to stop a fire from being spread.


  • by extinguishing
  • by cooling
  • by moving away the material that is on fire (if possible)

EXTINGUISHING and/or COOLING are the most frequently applied methods.

EXTINGUISHING often takes place in gas phase by applying Halogens.
Halogens are very effective but hazardous to human health.

Intumescents are another applied extinguishing method.
It takes place before the gas phase.

Intumescent means a substance which swells as a result of heat exposure, thus increasing in volume, and decreasing in density.
Intumescents are typically used in passive fire protection.

An intumescent consists of

  • a proton donator
  • volatile cat ions
  • a non-flammable gas
  • a carbon source

The choice of suitable chemicals for the intumescent primarily depends on the host material decomposition residues that shall be caught by the intumescent.

COOLING is an endothermic process that absorb heat energy.

Water has the lowest known thermal energy potential. That makes water to a terrific thermal energy cooling agent.
Salt is another chemical compound with a low thermal energy potential.
Salt is a chemical reaction between an acid and an alkali compound.
Different chemical compounds have different thermal energy potential.
Chemical reactions during decomposition that create water is often used as a cooling agent.


If the immune system of a human may fail to detect the difference between, say, a hormone substance generated by humans and an alien substance, that forms a serious health risk.

If an alien substance will stay in a human for more than 30 days that forms a serious health risk too.

"GREEN" labels - doesn't mean non-toxic.

Many flame retardant suppliers market products as harmless and environmentally friendly putting a "GREEN" label on the flame retardant products.

  • But is it really proved that the "GREEN" label products are completely harmless to humans and other living organisms?

  • What kind of test approvals have they passed before to guarantee no genetic impact on humans or other living organisms?

  • Much better than "GREEN" labels are if the chemical compounds are proved to be non-toxic.
    It is much safer for all to only use non-toxic chemical compounds, isn't it?


Flame retardants based on salts of Formic acid (meta-acid) also known as formate compounds are primarily used to impregnate wood in order to prevent fungus and rot to occur by killing all micro-organisms in the treated material area.
It is therefore difficult to understand how such flame retardants can be said to be harmless to human health. These formate are a significant burden on the ecological balance of nature especially as they are released over time due migration from the treated material.

Flame retardants based on ammonium compounds of various kinds are a risk both regarding human health and the environment. Ammonium compounds often decompose to form ammonia and sometimes even to form hydrogen cyanide which are known hazardous substances to inhale.
Furthermore, several of the current ammonium compounds (nitrogen compounds) are seen as fertilizers, which are proved in many cases the direct cause of eutrophication in nature with an adverse impact on the ecological balance of our nature.

Flame retardants in the form of organic phosphate esters release at the digestion a series of hazardous substances for humans and other organic life.
Phosphates also belong to the group of fertilizers with a high acidity of the environment. Therefore, it is difficult to understand how these organic phosphate esters can be said to be environmentally friendly substances.

Flame retardants of type halogens (chemical compounds of fluorine, chlorine or bromine) are today generally considered to be very harmful regarding health and the environment. It has led to that several manufacturers of flame retardants have chosen to compare their flame retardant products with a great group of halogens in order to appear "GREEN" and in the mirror of that being environmentally friendly.
Such a comparison has fallen far short regarding the demand on an accurate and true information in terms of classifying a flame retardant to be safe and environmentally friendly.
It is thus only minor nuances in the context of health-hazardous substances and not something else.


The REDFR-project initiated by FIRA (Furniture Industry Research Association) in UK supported by TSB (Technical Strategy Board) in UK tested 27 different flame retardants, all said to be eco-friendly and completely harmless to humans and other organic livings.
After 3 years of different flame retardant material tests it was proven that MHE® was the only flame retardant among the 27 competitors in the test that met the REDFR-project demands on both requested flame retardant functionality and being completely eco-friendly.

DOES MHE® treated materials meet the fire safety standards? - Yes!
