Welcome to Hydro Navitas Solutions

Thank you for finding your way to our website.

In an ever-changing world, it’s good to know we are all doing the right thing, but sometimes this is not easy. Here at Hydro Navitas, we hope to make your life a little easier as everything you find here is 100% biodegradable, non-toxic, non-corrosive, free of toxic chemicals and environmentally friendly.

We know we need to stop using harmful chemicals. If you are here, perhaps it’s because your existing firefighting agent, fire suppression systems, decontaminant or odour removal product contains one of those chemicals where their name seem to defy belief, or maybe you are looking for something that offers more benefits than just features, either way, we can help you. We need to save this beautiful planet of ours. All the products and solutions you will read about here are 100% naturally made and been developed over many years.

We hope you find what you are looking for. Below is a snapshot of each section and what we have to offer. If you don’t find the answers, just call.




** UPDATE APRIL 2021 **




Before you dive further into the website, we would like first to mention a family of chemicals called Perfluoroalkyl and Polyfluoroalkyl, commonly known as PFAS and menacingly known as the “FOREVER CHEMICAL.” They include PFOA (Perfluorooctanoic Acid) and PFOS (Perfluorooctane Sulfonate).




It has become apparent over the last few months that some of our clients are unaware of the issues faced with the continued use of PFAS based products such as Firefighting Foams. If you are a firefighter or commercial user of Fluorinated AFFF (aqueous film-forming foam) in your Fixed Fire Suppression systems, you need to know that they are PERSISTENT, BIOACCUMULATIVE and cause many HEALTH CONCERNS.

For many years, they were thought to be inert and nontoxic, but it became apparent that this was not the case at the turn of this century, and now the level of PFAS Global Contamination has caused several countries to ban their use, and here in the UK and Europe, we are trailing behind. PFAS compounds cause REPRODUCTIVE, DEVELOPMENTAL issues and IMMUNOLOGICAL disorders. Evidence has shown they increase the causes of some Cancers that affect firefighters.

As mentioned, there is a global drive to remove PFAS from many thousands of everyday items (over 4,700 compounds), not just firefighting foams. The IARC (International Agency for Research on Cancer) has classified PFOA and its compounds a Group 2B Carcinogen (ability to cause cancer to humans.)

Manufacturers of AFFF have been pushing the drive to move to F3 (Flourine-free foam); however, although F3 firefighting foams are free of PFAS compounds which is a good thing, the chemical compounds that replace the fluorine are equally invasive. We feel you need to be given the whole picture. So, we would also like to introduce another term you may not be familiar with, and this is BOD.



BOD stands for BIOCHEMICAL OXYGEN DEMAND, and why is BOD also significant? Why should you care about both PFAS or BOD?

You will find that most FRS (Fire and Rescue Service), Governing Bodies, and End-users of firefighting foams in the UK and Europe will find it challenging to understand why there are environmental consequences of using AFFF and F3 firefighting foams. AFFF are fluorinated foams, and F3’s are fluorine-free, so F3 don’t contain PFAS (the nasty stuff), so they must be environmentally friendly, right?? WRONG.

First, most FRS have not moved over to F3 foams and continue to use highly toxic AFFF on large impact fires such as Waste Recycling sites. These can burn for days or even weeks, and water struggles to extinguish these types of fires. FRS’s have been using F3 Class A foaming agents, on Grassland and Wildfires. But remember, most Class A’s are simply reformulated Class B foams with the Fluorine PFAS removed, but they are Equally Invasive, which is why knowing your BOD is so essential.

If you are going to use firefighting foams on grassland or other landmasses, you have a high probability of contaminating the watercourse or water body due to leaching through the soil leading to a river. Water bodies such as Rivers, Ponds, Lakes and larger bodies such as Reservoirs all require oxygen to survive. The Bacteria present breaks down the levels of Biodegradable Organic Material to keep it healthy, so if you change the BOD in the water, it can quite literally Asphyxiate Aquatic Organisms, causing a pollution event. Thankfully, we do not have many large scale pollutions events in the UK. We do have LOTS of small ones though.

The most notable pollution events were in 1988 Camelford, Cornwall. This was due to a leak of Aluminium Sulphate, which got into the drinking water. The other in 2005 at Buncefield, Hertfordshire during an Oil Refinery explosion, one of the largest peacetime explosion that resulted in a huge fire. Over 32,000 litres of water mixed with AFFF per minute was used during its peak. 26,000,000 litres of contaminated water had to be disposed of after this event. After the Buncefield fire, the public first encountered PFOS and what it could do to a river and they were introduced to the term “forever chemicals.”

It is the EA’s (Environment Agency) role to ensure our water bodies are not polluted. If you are a firefighter, you may be familiar with the request from the EA to “stop using water” at waste recycling fire. The EA request is not because they want to hamper you from extinguishing the fire, but it’s down to the sheer volume of water used and runoff of many 000’s litres of water that might cause a potential pollution event.

This risk is calculated in several different ways. The volume of water used is one, as the runoff can overpower a water body, but they will also look at the firefighting foam used. Firefighting foams are required to carry out a BOD test. There are several tests, each based on a number of days, but the BOD 5 is tested over 5-days and provides a good indicator of the toxicity levels. Firefighting foams are known to be very toxic due to PFAS and yes, F3 are less toxic, but as mentioned, they are equally Invasive, the EA does not want to add further different toxic chemicals to an already nasty mix.

So we ask all our potential clients to do a little homework. Find out what the BOD 5 count is on your existing AFFF or F3 firefighting foams. Ask for the MSDS (Material Safety Data Sheet). This will show the environmental impact and other related usage precautions. We already know the answer to most types, but in 2016, the Western Australian Department of Environmental Regulation, with Queensland Department of Environmental and Heritage Protection looked at the environmental management and potential impact of the use of firefighting foams.

Over 70 firefighting foams were used in this review. Products like Cold Fire will not show in this report. The chart below indicates AFFF in Green and F3 in Blue. The test was based on a 5-day trial looking at concentrate. We have added Cold Fire below the main table to give you an indication of just where Cold Fire fits, and as you can see, it is well below any of the others. The table shows the averages of these foams.




Average BOD 5 count…

AFFF BOD 5 Average is 220,000 mg/l.

F3 BOD 5 Average is 150,000 mg/l.



Cold Fire BOD 5 count is…

Cold Fire BOD 5 is only 30,400 mg/l.


The above figures are significant as they provide you with a simple indicator of the potential impact of the AFFF or F3. The higher the number that gets into a water body and the effect it might have. Do not be misled by some figures that use grams per litre (g/l) instead of milligrams per litre (mg/l). If your AFFF says 615 g/l this might sound low, but it is in fact 615,000 mg/l and that’s high. There are many things to consider when foam enters a water body. High flowing water and large water bodies are less likely to encounter a pollution event, but you should choose an AFFF or F3 with the lower BOD 5 if you can.

As you read through this website, you will see Cold Fire is 100% Naturally Made and 100% Biodegradable, so 100% Environmentally Friendly. It is essential to understand that Cold Fire is not a fluorinated AFFF or fluorine-free F3 alternative. It contains NO PFAS substances or compounds, and you will read later that this is verified by the US Department of Defense laboratory. Cold Fire, is FREE OF TOXIC CHEMICALS.

If you look at the difference between AFFF and F3 and then compare it to Cold Fire, you will see that using a different firefighting agent can have a huge impact on the potential environmental impact.


This means


Cold Fire is 86.19% or 189,600 mg/l lower compared to fluorinated AFFF’s average.

Cold Fire is 79.73% or 119,600 mg/l lower compared to fluorine-free F3’s average.



So what next?

Many PFAS Compounds are going, and this includes the compounds used in firefighting foams. The European Union states that PFAS compounds are ENDOCRINE DISRUPTORSPERSISTENT, MOBILE and TOXIC and VERY PERSISTENT and VERY MOBILE substances as categories of substances of VERY HIGH CONCERN.”

In their most recent report, the Commission will “ban all PFAS as a group in firefighting foams as well as in other uses, allowing their use only where they are essential for society. Some take the term essential for society as a possible get-out clause for their use, but this is very unlikely.

This means that fluorinated AFFF carried on Fire Engines, Foam Tenders, and used in Fixed Fire Suppression Systems, along with Fire Extinguishers and many other systems that use AFFF, will also be banned. We advise anyone using AFFF firefighting foam to start looking at a replacement, not soon or next year, but now. There is a lot of information out there, so carry out your research. The details quoted above can be found in this LINK and available in many different languages, so have a read.


So what are your options?

Many organisations such as the Military and Airports are moving to F3 firefighting foams as they have passed several International Standards such as ICAO (International Civil Aviation Aorthirty), LASTFIRE (Large Atmospheric Storage Tanks) and IMO (International Maritime Organisation), so they are seen as a viable alternative. However, they are not just a simple drop-in replacement. Manufacturers advise checking compatibility as AFFF and F3 do not perform identically and may require a change of equipment, and to ensure effectiveness, firefighters will need to adjust firefighting tactics.

It has been noted that Standards do not consider real-life firefighting. F3 can appear to be less effective, and more product is required. There is further evidence that F3 can draw fuel into the bubble layer and then the surface becomes flammable. We have seen this during our independent side-by-side comparison with Cold Fire. AFFF is on its way out. F3 may have its PFAS compounds removed, but they are equally invasive due to the replacement chemicals as you can see from the BOD, so all we ask is that you do your research before you look for a suitable alternative to your foams.

As you read on, just remember two things, PFAS and BOD.



move away from toxic chemicals to something altogether more natural, 100% natural



Below you will find a snapshot of our divisions. Each provides you with a range of 100% Naturally Made, Non-toxic, Non-corrosive, Free of Toxic Chemicals and 100% Environmentally Friendly solutions.

Please have a good look around. Each section offers you an incredible level of both features and benefits. We believe that many of these you will not find elsewhere; however, if you have any reason to question any of our claims and you read them and think, really?!?! Let us come and show you. Trust us; there is nothing better than seeing what we have to offer in the flesh.



Cold Fire Firefighting

We have a range of Cold Fire wetting agents for firefighting. Each offers the same incredible extinguishing abilities and will provide the very best firefighting wetting agent. You can rest assured Cold Fire is not be one of the many firefighting agents being removed across the globe due to their high level of toxic chemicals. Cold Fire is and always will be GREEN and 100% Naturally Made.

We offer a premix Winterised version of Cold Fire. Depending on your requirements, this remarkable blend can work between temperatures from -28°C (-20°F) and right down to a rather chilly -53°C (-65°F).

So we supply Cold Fire to the following industries;  Commercial. Emergency Services. Motor and Marine. Aviation and Military.



Custodian Fire Suppression

Here you will find out why many manufacturers are now swapping out their existing AFFF (aqueous film-forming foam) and moving over to Cold Fire in their fire suppression systems. For many years their options have been limited to Water, AFFF or Dry Powder! Now there is another option, Cold Fire.

Motorsport has been using Cold Fire for many years. IndyCar, NASCAR, Drag Racing, Now for the first time ever, the Fédération Internationale de l’Automobile (FIA) use Cold Fire in one of their Holmolagation FIA 8865 in-car vehicle suppression systems.

From in-car vehicle systems to fixed automated cannon fire suppression systems. One of the hardest-hit industries for fires has been Waste Recycling. Today, many sites are protected by systems using Cold Fire. It is one of the only firefighting agents that can deal with and extinguish lithium-ion batteries. There are so many more areas where fire suppression systems can benefit from Cold Fire. Some of these might just surprise you.

Fire suppression comes in many forms. We can supply small portable Bag-on-Valve units right through to fully automated systems that monitor heat variations across an area. But sometimes suppression can mean stopping the material igniting in the first place. We can do that also.


We have another truly remarkable product called Fire Block that protects nearly anything it is applied to. This simple to use pre-mixed product is also 100% naturally made. It protects against FLAME SPREAD and SMOKE DEVELOPMENT. All you do is spray and allow it to dry. Like everything we provide, it has also been through some of the hardest tests for this type of product. US NFPA 225 & ASTM-E84 tests are large scale tests for flame spread and smoke development, this has also been independently tested by SGS (Standard Global Services) the world’s leading testing groups for Class A materials. It also has NFPA701 (fabric retardancy) for textile fabrics. It also has BS 5867-2:2008 Part 2 (Fabrics for curtains, drapes and window blinds) and BS 7177:2008 + A1:2011 (Flammability Testing of a mattress – Natural latex).

There are many new exciting developments happening in this part of our business, so pop back often for updates.



Acid-Stop Decontaminant

Acid-stop was developed for industries that on a daily basis use some of the most toxic and caustic chemicals. Sometimes through no fault of the manufacturing process, these can spill, spray or leak from seals during the production process. As you can imagine, the people who work with these chemicals dress in the type of protective clothing that, on any other occasion, you could mistake them as astronauts. They have some of the highest levels of safety procedures, but they still have to deal with this and need a product that can safely minimise this risk.

There are products on the market that work with the above and they use different methods to achieve similar results. Some use chemicals that react with the spill and produce a less harmful finished chemical, others use highly porous minerals that enhance absorption and provide neutralising characteristics and, some use the process of ‘wicking’ and remove the chemical from the surface. Acid-stop is different from all of these. Our range can be carried on you in small units, or used via our range of pressurised sealed units or pump-to-use units.

Acid-stop is different from all of these, In that, it immediately decontaminates the affected area and/or person. Our range is powerful enough to be available in belt-mounted small canisters for personal use or used via a range of pressurised sealed units or pump-to-use units.

Due to the unique nature of Acid-stop, we were fortunate to get government funding to carry out extensive trials. We were incredibly excited to learn that not only did Acid-stop neutralise acids, but it also neutralised alkalines.

This places Acid-stop in a unique list of products that can work across the whole pH Spectrum (0 – 14) and neutralise both ACIDS and ALKALIS.


Acid-stop was developed for industrial applications, but you may be aware that the UK has one of the highest cases of CORROSIVE attacks in the world; this is both startling and true. London has the ominous title of the ‘acid attack hotspot‘ of the western world, and the youngest victim was just ten years old. Just writing these words for our website is incredibly concerning, but the level of devastation an attack brings to everyone involved is immeasurable and due to the method of the attack and its visible results, last a lifetime. Due to the complete safe-to-use nature of Acid-stop, the UK Police are looking at possible front-line use to help with these types of attacks.
