How does it work?
A highly stable solid charge of the aerosol forming composition is contained within the sealed generator. Upon activation of the initiator, the charge begins a controlled burn producing an ultra-fine aerosol, which is ten times as effective as any agent currently on the market. The effective aerosol passes through a series of oxidation and cooling filters, where the temperature of the aerosol is rapidly reduced before it escapes through the discharge ports of the generator at low pressure. Generator placement within the hazard area provides proper flow and distribution of the highly effective aerosol within the protected volume.
Compared to current technologies, this product is the first to generate Nano-meter level particles through high temperature for fire extinguishing, making this technology not only an improvement for current fire extinguishing method, but a discovery of a new fire extinguishing theory.
The principle of this technology is that fire extinguishing substance is made up by aero genesis agent and fire extinguishing agent. Aero genesis agent will generate a large volume of gas as well as heat by redox reaction. Fire extinguishing agent generates Nano fire extinguishing agent after being heated, which is then discharged from the nozzle carried by the gas generated from aero genesis to achieve powerful fire extinguishing capacity.
The working principle of nano particles fire extinguishing product is as follows.
Are the aerosol generators re-chargeable after discharge?
No. The units are designed for single use only. After discharge turnaround time is minimized as re-connection of a new generator is quickly and easily accomplished.
How does it extinguish fires?
Unlike other agents that work by reducing oxygen levels or by cooling, the aerosol extinguishes by chemical interaction with the free radicals that fuel the growth of the fire — in the same manner as halon did. The aerosol stream contains ultra-fine (1-2 micron) particles of potassium compounds that provide a large surface area interaction with the fire. In the fire zone the free potassium radicals bind with the free radicals of the fire (O, OH, H) to rapidly slow and extinguish the fire.
How effective is it?
The Extinguisher Sticks JE-50, JE-100, JE-150 and JE-300 are extremely effective. 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.
Does it reduce the Oxygen level?
No, oxygen levels are not affected.
Is it safe for sensitive equipment?
The Extinguisher nanoparticles 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 the Extinguisher Sticks have 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 nanoparticles agent 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 ≤ 2µm 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. In tests conducted by certified, accredited testing facilities in Asia, Europe and the United States, JE 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 Extinguisher Sticks do 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, on-site maintenance and housekeeping may have been lax allowing accumulation of dirt in the enclosure. During discharge, any dirt within the enclosure will be blown around and then deposited as unwanted residue throughout the area. Also, in rare cases, unit orientation may have been altered improperly or equipment may have been re-oriented within the protected enclosure resulting in an improper discharge directly onto a wall 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 any agglomerated particulate be cleaned up with a water/alcohol solution no later than 24 hours following a discharge.

What is the difference between nano particles fire protection technology and aerosol fire protection technology?
At first look, nano-particles fire protection technology and aerosol fire protection technology seems to be very much alike in terms of product outlook and the form of fire suppressant. It appears that nanoparticles fire protection technology is but a development to aerosol fire protection technology, and they are essentially the same.
But the truth is that nanoparticles fire protection technology and aerosol fire protection technology are fundamentally different not only in terms of work principle but also in application scope, and they are two different kinds of fire protection technology.
In terms of work principle: the fire extinguishing material of nanoparticles fire protection technology consists of gas generating agent and fire suppressant. Gas generating agent generates large amount of heat and gas in the process of oxidation reaction. Fire extinguishing agent gives out nano-level fire extinguishing particles, which will be carried by the gas generated by gas generating agent and discharged from the nozzle. The fire extinguishing material of aerosol fire protection technology consists of only fire suppressant, which generates large amount of fire extinguishing particles and is discharged from the nozzle after cooling down in the device to put out the fire. It can be seen from above that the work principles of these two technologies are fundamentally different.
In terms of application scope: large amount of potassium oxide particles is generated after the discharge of aerosol fire suppressant. Potassium oxide will easily absorb water when exposed to air and turn to potassium hydroxide solution, which is highly caustic and can cause serious damage to the electronic equipment. Therefore, aerosol fire protection technology is not suitable for places with precision electronic equipment. But nano-particles fire protection technology doesn't cause any damage to electronic equipment and can be used at places with precision electronic equipment. Whether it can be used at places with precision electronic equipment is, for fire protection technology, a fundamental difference.
Apart from above the two fundamental differences, nanoparticles fire protection technology is more efficient and safer compared to aerosol fire protection technology.
Therefore, nanoparticles fire protection technology is not only fundamentally different with aerosol fire protection technology, but also is a new fire protection technology far superior.
Does it deplete the Oxygen in the room?
No, there is no oxygen depletion or reduction. The First Responder stops fire by interfering with the chemistry underlying fire not by changing the atmosphere.
What if someone is trapped in the room?
The aerosol will be the least of their problems. While the aerosol may cause minor mucous membrane irritation at high concentrations (over 100g/m3) or if there is long exposure, the combustion products and heat of a fire can be, and often are, deadly. In a real world fire scenario the by-products and composition of the aerosol are insignificant relative to those of a fire. At a 100g/m3 density the gas products of the aerosol are many orders of magnitude less than that allowed for automobile airbag systems. However, the First Responder should not be thrown close to the victim as it emits a hot cloud of aerosol close to the unit.
Is the unit pressurized?
The unit is NOT pressurized prior to activation. When activated, a controlled burning reaction of the solid aerosol forming compound inside the First Responder converts the solid to an aerosol composed of 40% carrier gases (primarily nitrogen and small amounts of water vapor) and 60% ultra-fine particulate. The unit operates at relatively low pressure.
How long is the aerosol effective for?
The aerosol has a long hang time providing extended protection up to an hour in a truly sealed, confined space with no airflow. However, in real world deployments the aerosol will typically escape through doors, windows, or other openings. But as long as the aerosol cloud is present, it will continue to provide suppression against a fire.
What types of fire extinguishing technologies exist?
- Water based and foam technology: They are the best choices for class A and B fire, but they cannot be used to extinguish electrical fire;
- Gaseous fire suppression technology: including CO, FM200 and Inert gases. While its performance may not be as good as the first category, it can be used to extinguish electrical fire without damaging electrical devices;
- Chemical powder technology: which has good performance for class A, B, C (electrical fire) fires, but it will leave residue and may damage the equipment’s under protection.
Even though above three technologies have their own advantages, dry powder has been gaining popularity due to its advantages including non-conductivity, good performance and compatible size. It is thus called omnipotent fire extinguisher. The performance of dry chemical extinguisher depends on its ingredient and the size of the particles released. After about a hundred years of study and research of all possible materials, phosphate has been chosen as the main chemical ingredient. There has been not much development in the ingredient for decades since then. For the size of particle, superfine dry power has been launched. Currently, the diameter of the finest dry powder is 5 /.L m. which has notably increased the performance of such powder.
The nature of the nano particles fire extinguishing technology is that it has greatly reduced the size of dry chemical particles. The key point is to heat the fire extinguishing substance to generate Nano extinguishing particles, and to generate momentum to push such fine particles to the fire. The size of fire extinguishing particle under this technology is about 0.1 /..L m. Dry chemical particles of this size not only has good fire extinguishing capacity, but also match the characteristic of gas fire extinguishing agent which is good at avoiding obstacle and suspending in air.
Therefore, this technology can be described as a nano extinguishing particle technology.
What are the advantages of nanoparticles extinguishers?
Conventional chemical powder is of large size and more often than not very bulky, and can only be placed at certain designated areas. Chemical powder is often stored in pressure vessel, which has risk of explosion. Also, chemical powder leaves residue (can be very hard to clean), it can also damage equipment and electrical facilities, and it also has proven adverse effect to human health.
Nanoparticles fire extinguishers are small, look nice and can be attached to walls for easy access. II contains no pressure during storage, requires no maintenance, and doesn't have any explosion risk. It leaves only a few residues after operation, it's non-conducting, and will not in any way damage equipment and electrical facilities.
