Firesorb®

When using FIRESORB® in combat you use a lot less water because fires can be extinguished more quickly. A further spreading of the fire is prevented, so that the whole amount of extinguishing water and waste, which has to be disposed of, is being reduced considerably. When used as preventive fire protection FIRESORB® reduces the ecological and economical damage and thus serves the environment.

Waters
FIRESORB® MO is classed as water danger level (WDL) 1, which means it is a "minor water hazard". The components which are responsible for possible effects on water organisms (algae and Daphnien) are biodegradable. In addition, when using FIRESORB® to extinguish fires, you only use a 1-2-per cent of the dilution. Thus we do not expect a long lasting toxic effect in the waters. But even so we recommend not to let FIRESORB® get into open waterways.

Background: At the moment matters and mixtures are classed into three water-danger-levels (WDL) in compliance with the "administrative regulations water-hazard matters". WDL1 includes matters which fall under "minor water-hazard", WDL 2 is "water-hazardous" and WDL 3 includes matters which fall under "major water-hazard".
The optimal improved FIRESORB® as non diluted product has been classed into the "best" of the three Water-danger-levels, as a WDL Zero does not exist any more.

Ground
Because of its polymer structure and its poly-electrolyte characteristics FIRESORB® stays in the top ground layer and does not seep into the ground water. Stockhausen used this very principle with a different product on the basis of the super absorbers: STOCKOSORB®. STOCKOSORB® is a granulate used for ground improvement. The gel particles are purposefully worked into the ground, this stimulates the root-growth and provides water for the plants more effectively.

The oil-phase, fatty acid esters, are easily biodegradable.

In an experiment earth worms were put into the ground which contained FIRESORB®. No negative effects could be observed on the earth worms, even in high concentrations - with more than 2 grams of FIRESORB® per kilogram earth.
 
Because the extinguishing-time is reduced to 50 per cent, less fire-emissions are released correspondingly.
 
FIRESORB® is a preparation consisting of a polymer and an organic phase. The polymer is not biodegradable. The organic phase consists mainly of rape-oil-, fatty acid-, methyl ester. The rape-oil is a naturally re-growing raw material and is easily biodegradable.
When burning FIRESORB® no particular danger exists: A fire-gasses analysis (easy and complete) has shown this.

FIRESORB® usually does not burn. Should this happen anyway when very high temperatures and reductive circumstances there is the possibility that a very small amount of prussic acid is released. These small amounts though can be ignored. The prussic acid released from the actual fire is many times higher (refer to the answer of question 4).
 
Extinguishing-water should be tested for contamination before letting it into a sewage plant.

FIRESORB® does not have a distinct toxic effect on micro-organisms and thus should have no negative effects on the biology of sewage plants when used in diluted form. The oil-phase is easily biodegradable and the polymer body is bound to the sewage sludge

If a 1-per cent watery FIRESORB®-mixture is let into a sewage plant it should be diluted 50 times. As an example this means that, for a community sewage plant with a commuter area of 50.000 inhabitants (corresponds with 0,02 m3 sewage per hour x 50.000 inhabitants = 1.000 m3 sewage per hour): with a dilution aimed at the factor 50 (1000³ : 50 = 20 m³ ) of the used 1 per cent watery FIRESORB®-mixture you could let 20 m3 extinguishing water per hour into the sewage plant without any negative effects on the plant.
 
No. If, for example, a natural matter, which caught fire, is extinguished with FIRESORB®, the fire remains do not progress to become "hazardous waste". A fire in a sugar plant has proved this. Here sugar beets caught fire and could not be extinguished with the conventional extinguishing methods. With FIRESORB® the fire was brought under control. The burning material was afterwards disposed of under official supervision in a domestic waste burning plant.

It the fire is not a mono fire like the one with the sugar beets but rather a house- or industrial fire, the fire remains are usually classed as "waste in need of special monitoring", which has to be disposed of in special waste burning plants or on special dumps.
 
Inhalation tests have shown that there is no acute danger when inhaling FIRESORB®. In addition to this, fires are always extinguished with the direction of the wind, so the chances of inhaling FIRESORB® are very slim. Tests have been done concerning the measuring of the exposure of people when using FIRESORB®. The aerosol-fog which is created when spraying with a C-pipe did not contain any measurable amounts of FIRESORB®. When testing the acute inhalation danger of a FIRESORB®-water-mixture no toxic effects have been observed, even on the highest test concentration (5000 mg/m3).
The highest possible exposure as well as the result from the acute inhalation dager tests do not conclude to a health hazard through the use of FIRESORB®.
 
No, FIRESORB® is not irritating for the skin or the eyes. Thus the common safety measures are sufficient: If FIRESORB® gets into the eyes rinse thoroughly with plenty of water. When in contact with the skin wash with water and soap. Dirty clothing can just be taken off and washed in your normal wash.
 
Because of the tests done so far on the acute oral danger there is no need to believe there are any toxic effects.
 
It is our ongoing duty to optimise our products in accordance with the wishes of our clients with regards to environmental issues. So, FIRESORB® as well has already been modified. The further developed FIRESORB® has been classed into water "danger" level 1, which means it is a "minor water hazard" (before: 2 "water hazardous").

The optimised product FIRESORB® thus has a lower eco-toxic effect and does not need to be especially marked any more.
 
It is not absolutely necessary for things to be cleaned. If though, objects have to be cleaned after, for example, a house fire, we recommend to let the gel dry first and hen brush it off. If there are larger outdoor areas which have to be cleaned it is sufficient to just rinse it off.
 
Needle thickets showed no visible effects after the use of FIRESORB® . Although we did observe in tests with deciduous trees that their leaves became yellow and sometimes fell off. But in the next vegetation phase the leaves were sprouting again.
 
When there is a fire - whether it is a forest area, a furniture store or a car factory - the important thing is to extinguish the fire as fast as possible, or to bring it under control. The aim is to minimise the damage for people, the environment and objects. Because of the acid gases released through, for example, burning synthetics or processed wood the danger limitation is the ultimate goal when extinguishing the fire.

So, if FIRESORB® could extinguish a fire with tyres which could not be extinguished with the conventional extinguishing devices or -measures, FIRESORB® is more gentle to the environment through its shorter burning time. Thus less amounts of carbon monoxide, prussic acid, Furane and dioxins as well as PAKs are created.
