Stat-X FAQ's

Stat-X is an extremely effective solution for fire suppression within marine applications. Tests on class B fires have shown it to be 5 times more effective than halon and 10+ times more effective than other currently available halon alternatives. This dramatically reduces weight and space requirements, which are always at a premium on any boat.

Stat-X Fire Suppression
We work closely with Stat-X systems to provide
effective and reliable systems across the UK & Europe
Stat-X Fire Suppression Systems

Stat-X systems are also extremely cost effective. While actual costs will vary based on the size of the enclosure, leakage, and class of hazard, in general, an installed system will be significantly less expensive than alternatives. For more information on Stat-X fire suppression, see below for some of the frequently asked questions we get asked here at Marine Fire Safety.

Is a Stat-X system expensive?
No. Stat-X systems are extremely cost effective. While actual costs will vary based on the size of the enclosure, leakage, and class of hazard, in general, an installed system will be significantly less expensive than alternatives. This is due to the small amount of agent required and the fact that installation costs are dramatically reduced because of the elimination of distribution manifolds, piping, and nozzles. In some cases Stat-X thermal units could be considered for fuel storage areas, electrical cabinets, inside generator casings, etc and this where appropriate could further reduce costs due to the elimination of detection and control panel requirements.
 
What type of boats does Marine Fire Safety supply Stat-X to?

Does it reduce the oxygen level?
No, oxygen levels are not affected.
 
Is it safe for the environment?
Yes, Stat-X is very environmentally friendly with no global warming potential (GWP) and no ozone depletion potential (ODP).
 
What is the service life?
The service life of Stat-X generators is 10 years+.
 
Have Stat-X systems put out fires in the real world?
Yes. Marine Fire Safety has attended several boats in the past where the FPX/Solo control panels have detected a fire and the Stat-X system was needed to be deployed. In all instances the fire was extinguished and there was no re-ignition of the fire and no damage to machinery from the Stat-X aerosol. In these instances Marine Fire Safety will aim to attend the boat within 24hours after initial contact to reinstall new Stat-X generators and re-commission the system to enable the boat to go back in to full use once the cause of fire has been determined and fixed. Stat-X have also had a number of very successful incidents in other areas, in particularly with CNC machines and mining equipment where a relatively small investment in a Stat-X system has saved high value equipment with very minimal downtime. Stat-X is installed on several thousand military vehicles serving in Afghanistan where reliable fire protection is mission critical.
 
 
Where can it be used?
Stat-X is the perfect choice for protecting engine rooms and machinery spaces. Although it is an aerosol it shares many of the flow characteristics of a gas. It is suitable for use in un-occupied and normally un-occupied enclosed volumes and has the added advantages of extended hold times and as it is non-pressurised, less susceptibility to leakage. In addition, Unlike HFC's, which can break down and produce deleterious compounds such as hydrofluoric acid when exposed to elevated temperatures, Stat-X does not break down when exposed to a fire.
 
Are the aerosol generators re-chargeable after discharge?
No. The units are designed for single use only. The benefit of this is that after a discharge turn-around time is minimised as re-connection of a new generator is quickly and easily accomplished. In some cases, spares can be easily carried.
 
Is it safe for sensitive equipment and machinery?

Stat-X aerosol has been tested on a wide range of materials including structural, aviation composites, and materials commonly used in electronics, and circuit boards. In all cases it has been shown that Stat-X has no deleterious effect on the operating capability of equipment.

Due to the ultra-fine particle size and the method of generation, the particulate is quite buoyant and suspends in the gas/air mixture within the protected enclosure. Because of this "buoyant" effect the aerosol does not begin to "settle" for an extended period and, therefore, is extremely easy to vent from the protected area. Only very minor amounts of particulate may be deposited on equipment and, generally, there is no need to do anything beyond extraction of the air within the protected volume through a fan or air handling system followed by a blow down with compressed air. Any particulate deposited on horizontal surfaces will be less than 2 microns and will not form a continuous layer. Large gaps will exist between particles leaving no potential for electrical conductivity issues to develop.

As a precautionary measure, however, it is always good practice to inspect and clean the site thoroughly following a discharge. While the aerosol itself is quite "clean", environmental factors are also a consideration. The unknown, and potentially harmful, by-products of an actual fire pose the biggest risk to sensitive electronic equipment. Because unknown products from the fire itself may be present, it is always recommended that equipment be blown down with air or vacuumed following a discharge to insure that no unwanted by-products from the fire itself are present.
 
Is it safe for personnel?
The aerosol, itself, consists of solid and gas combustion products. The solid phase is composed of highly dispersed particles that present insignificant health hazards for humans at normal design concentrations. The gas phase may contain very small amounts of carbon monoxide CO, carbon dioxide CO2, nitrogen oxides NOx, and ammonia NH3. Production of these gases is minimal in the case of Stat-X due to its patented construction, chemical formulation, and its manufacture in the United States using only technical and reagent grade chemicals. In tests conducted by a certified, accredited testing facility in the United States, Stat-X generators were shown to produce gas levels several orders of magnitude less than the standard allowed for automobile airbag systems for passenger vehicles.

While the components of the aerosol are not considered toxic at normal concentration levels, ingestion of the ultra-fine particulate may cause short-term discomfort and unnecessary exposure should be avoided. Exposure to the aerosol is generally of less concern than is exposure to the decomposition products of a fire. Accidental exposures under ten minutes are normally considered safe. There is a high obscuration factor with the aerosol and a 30 second time delay and system lock out switch should be used whenever personnel may be present in the protected space.
 
Is it a clean agent?
The term "clean agent" has traditionally referred to gases. The term itself is inaccurate as all agents may pose post discharge issues. The Stat-X aerosol does contain ultra-fine suspended particulate which is very buoyant and hangs in suspension for extended periods. Because of this, settling is minimal and removal of the aerosol can be accomplished easily by venting. While the aerosol itself is quite "clean", environmental factors are also a consideration. The unknown, and potentially harmful, by-products of an actual fire pose the biggest risk to sensitive equipment. Because unknown products from the fire itself may be present or because of unwanted environmental conditions, it is always recommended that the area is thoroughly cleaned to insure that no unwanted products are present. For example, onsite maintenance and housekeeping may have been lax allowing accumulation of dirt in the enclosure. During discharge, any dirt within the enclosure may be blown around when the Stat-X generators discharge and then deposited as unwanted residue throughout the area.

Also, if the Stat-X units are not installed correctly focussing on the unit orientation or if they have been altered improperly or equipment may have been re-oriented within the protected enclosure resulting in an improper discharge directly onto a bulkhead or equipment surface. This could result in the deposit of small, localized areas of highly concentrated agglomerated particulate on that surface. If left untended, an agglomerated mass may take on moisture and may cause non-progressive surface discoloration (copper, bronze) of unprotected metal surfaces. It is therefore, important that firstly the units are installed correctly and in the unlikely event of any agglomerated particulate, it should be cleaned up with a water/alcohol solution no later than 24 hours following a discharge.
 
What are the space requirements?
The Stat-X generators are small, self-contained units that are mounted at ceiling height in their own brackets. They do not take up valuable floor space as conventional systems do and they do not require piping and nozzles so will not inhibit on other machinery or walkways.
 
What is a Stat-X thermal unit?
Stat-X thermal units are suitable for small enclosed spaces such as electrical cabinets, fuel storage areas, generator housings, lazarette spaces, etc. The units are self contained and utilise a patented thermal detector that is integral to the generator. This eliminates the need for ancillary detection and releasing devices. Units are available in several temperature settings to insure applicability to the hazard being protected.
 
What about maintenance costs?
Maintenance costs related to the generators themselves are minimal and involve only periodic visual examination of the generators and protected space to insure that the generators have not been damaged and that the system installation and space remains in the same configuration as that originally designed. However as with any fixed fire suppression system, be it a manual or electrical operated system, the functionality of the system and any detection and ancillary devices should be checked annually. Marine Fire Safety has a team of engineers who can and do carry out annual maintenance work throughout the UK and parts of Europe on a regular basis.
