A report that provides information on the growing use of carbon dioxide fire extinguishing systems, particularly in the marine market, considers the personnel safety risks from use in occupied areas, and compares these systems to halon and other halon alternatives.
Portable extinguishers present a special challenge since they must be capable of extinguishing a range of fire types - solid materials such as cabin fixtures and furnishings, flammable liquids and electrical fires.
Fire bottles in engine compartments are usually electrically operated after manual selection by the flight crew based upon automatic fire detection. In the airborne case, APU fire bottles are similarly activated but it is usual for automatic APU fire detection during ground operation to trigger automatic shutdown and fire extinguisher activation. Until recently, the most common extinguishing agent was Halon 1301 for all Engines/APUs fitted to civil transport aircraft. However, Halon 1301 is no longer manufactured and has been banned (for new systems) since 1994; often they are now replaced by HFCs (Hydrofluorocompounds).
Toilet waste bin fire extinguishers are activated automatically if heat detectors in the vicinity are activated. Toilet smoke detector activation does not trigger waste bin fire extinguishers. Alternative extinguishing agents to Halon 1301 have been approved for use in fixed toilet waste bin systems and have also been, uniquely in terms of the search for Halon alternatives, shown to be more effective than Halon 1301 units whilst being the same size. Since only a documentation change is required to fit these alternative extinguishers, they have been used for retrofit as well as in new-build aircraft.
Evaluating the integrity and compatibility of fire extinguishing systems components, from the cylinders that store extinguishing agents to the detection, actuation, and distribution piping and discharge devices.
We test to UL Solutions-developed safety and performance standards for extinguishing systems that are designed, installed and maintained in accordance with National Fire Protection Association (NFPA) standards. Certified components are correlated to the applicable standards, helping simplify both the design and testing process for you.
Traditionally, halogenated hydrocarbons (halons) have been the only fire-extinguishing agents used in civil transport aircraft as fire extinguishers because they are effective on different kinds of fires and they are very lightweight. However, due to their high ozone depletion, the Montreal Protocol on Substances that Deplete the Ozone Layer called for an end to their production by 1994 in developed countries and by 2010 in developing countries. As a result of this international agreement, production of halon is prohibited, and halon supplies are diminishing. The updated breakout of Global Inventories of Halon 1301 from the United Nations Environment Programme (UNEP) Halons Technical Options Committee (HTOC) 2018 Assessment Report is shown below.
At present, halons are used for fire suppression on civil aircraft in four extinguishing applications as shown above. Worldwide, there are many States and organizations testing alternatives to halon. Unfortunately, there is no single substance which can be used for all of the extinguishing applications. Therefore, aviation will have to use different types of extinguishers for each application.
Halon replacement agent for portable and lavatory fire extinguishers which are reported to be neither a greenhouse gas nor an ozone-depleting substance are already available. Research and development are progressing towards halon replacement for engine and auxiliary power unit (APU) fire extinguishing systems. However, the industry is still far from developing a viable replacement agent for this application that can be fully tested, certified and implemented on commercial transport aircraft. The cargo compartment extinguishers are the most difficult to replace, research and testing still have a long way to go. Halon replacement will require the full cooperation of all stakeholders to collaborate under the auspices of ICAO to achieve a viable solution which provides adequate technical performance, certification, and long-term environmental benefit.
A spark extinguishing system (also known as spark detection and extinguishing system") is used for preventive fire protection. A spark extinguishing system can detect and eliminate ignition sources before a fire or dust explosion occurs. Systems for grinding, chopping, drying, cooling and pressing materials including their pneumatic or mechanical transport and extraction systems and facilities for separation or storage purposes, also dust collectors, filters, cyclones, silos, and hoppers are especially at risk.[1]
Spark extinguishing systems are established as preventive fire and explosion protection systems in the industry and craft. Nowadays, many industries could not be operated economically without spark extinguishing systems. Technically they are the only preventive fire protection. Other measures, such as explosion suppression or sprinkler systems, are called reactive measures.[2]
In most cases, the conditions for fires or dust explosions are not met in pneumatic conveying paths. So it is possible to equip these systems with spark extinguishing systems as preventive fire and dust explosion protection.
The control console is the center of a spark extinguishing system. It receives signals from detectors and activate preprogramed countermeasures. All signals of the individual spark detectors from different parts of the facility come together at the control console. The connected extinguishing equipment or the alarm relay output of the corresponding detection zone is activated without delay.
In most cases extinguishing is done with water. The automatic extinguishing device is installed in direction of the conveying flow downstream of the spark detectors. Spark detectors and extinguishing device must be arranged in a certain distance to ensure that the detected ignition source can be extinguished reliably. This distance is called quenched spark gap and is calculated based on the transport speed of the material and the system-related delay time.
The automatic extinguishing devices temporarily generate a water fog in the pipe section for sparks to fly into. If no more sparks are detected, the injection is stopped automatically; production can continue without any problem.
An optimal extinguishing effect is achieved by the specific surface of the water being kept as large as possible which is reached by a very fine nebulization of the water. A special nozzle and sufficient process water pressure provide for the nebulization degree. Also hydrophobic substances, such as rubber or plastic, can be extinguished or the water quantity can be minimized by adding relaxant agents.
Therefore, deflectors for material bypassing purposes or sliders and flaps to shut off the conveying flow are used in such systems. The reaction times of these mechanical systems are as short as the water extinguishing.
The history of spark extinguishing systems goes back to the early seventies, when the Federal Anti-Pollution Law (BImSchG) of 1974 required the use of exhaust and dedusting systems in the wood-based material industry.[6] For this purpose, operators of chipboard and fibre board facilities were committed to comply with the administrative regulations called Technical Instructions on Air Quality.
A fire and explosion hazard caused by sparks or hot particles exists everywhere where combustible material is machined or processed, transported, filtered or dried. A spark extinguishing system can prevent fires and dust explosions.
Detecting a spark in a pneumatic material transport duct at speeds that often exceeds 5,000 feet per minute requires a very sensitive and very fast sensing device. FLAMEX Spark Detectors provide the sensitivity, speed, durability and reliability that such an application demands. Two or more spark detectors will be required to monitor a duct cross-section depending upon the size and configuration of the duct. These detectors are ideally mounted on a main section of ductwork downstream of any material input branch ducts and sufficiently upstream of the proper location for the extinguishing assembly to be installed. Upon detection, the detectors cause the system to activate thereby triggering the extinguishing device and causing the panel to go into an alarm state. The detectors automatically and immediately reset themselves so that they stand ready to detect any possible subsequent sparks.
A fully automatic spark detection & extinguishing system consists of spark detectors, a control panel and an automatic extinguishing system as standard. If the spark detectors have detected sparks or hot particles in the conveyed material, they send a signal to the control panel. This then controls the solenoid valve of the automatic extinguishing system in the millisecond range. The extinguishing water is released and introduced into the conveying flow via patented self-closing nozzles. The glowing particles fly into the water veil built up by the nozzle. Immediately afterwards, the solenoid valve is automatically closed again. At the same time, the alarm is triggered. 2ff7e9595c
