Answer Upon - Safety for Your Production: Spark Detection Systems Reduce Your Risk of Fires and Explosions
Your next presentation is just around the corner. To ensure devastating impact, just follow these ten steps and watch your career catch fire.1. Avoid Excessive ResearchResearch is for geeks and bookworms. Do you really want to bore your audience with a bunch of statistics and facts that they can easily get from the library or from Google?You want to tell people your version of how things work, not someone else’s ideas that have been posted all over the Internet already.2. Be SpontaneousPreparation and rehearsals are for amateurs, or actors. By practicing your presentation you only sabotage your chances for spontaneity. Just scribble down a few notes and stuff them in your pocket in case you need them for reference. This allows you to improvise as you go, keeping your talk lively and interesting. People hate predictability.Plus, by rehearsing your presentation you run the risk of having a bunch of know-it-alls give you unwanted feedback, which may tempt you to make last-minute changes. Do you really want to start over? Remember, this is YOUR show!3. Always Start 15 Minutes LaterWhen you go to a 7:30 movie, what time does the feature presentation actually start? Around 7:45. There are usually at least 15 minutes of commercials and previews, to allow people enough time to settle in for the big show.If this strategy works for multimillion-dollar movies, it will work for you too.Besides, if you start your talk right on time you’ll only get distracted by the latecomers.4. Calm Your NervesTo avoid getting nervous prior to your presentation, have a big meal and an alcoholic beverage right before you start your talk. Both will help you relax to the point where you wish you could take a nap. If food and beverages are not available at the time, head to the nearest pharmacy and get some cold medicine or sleep aids. But don’t overdo it
Spark Detector FM 3/8
The FM 3/8 detector is used in applications with operating temperatures above 149°F (65°C) as can appear in drying processes, for example. Spark radiation is carried through fiber optic cables to the detector.
Daylight Spark Detector DLD 1/8
For the most reliable detection of glowing or hot particles, no ambient light can be present at the sensor location. However, where an absolute dark surrounding cannot be guaranteed, sensors that aren’t sensitive to daylight or ambient light are used. These sensors operate only in the infrared spectrum of light so they can be installed at open transfer points or on conveyor belts.
Thermo Detector TM 1/8
The thermo sensor TM 1/8 is used for the additional inspection of large areas, like filter and silo systems. Its task is to monitor these areas for self-ignition of the material being conveyed or stored.
The Extinguishing Device
Water is the best extinguishing agent. Its excellent extinguishing efficiency mainly results from the high ability of heat absorption. For this reason it has a strong cooling effect that prevents re-ignition of the combustible materials.
To obtain an optimal extinguishing efficiency, the area covered by the water must be kept as big as possible. This is accomplished by a fine atomization of the water. Atomization is achieved through a special nozzle and sufficient operating water pressure. With high atomization, the amount of extinguishing water can be minimized so that filter elements are not damaged by an excessive amount of water. This allows production to continue while extinguishing takes place.
The operating pressure of the extinguishing device should be at least 60 PSI at a flow rate of 24 GPM per nozzle. If this pressure is not available, a pressure-increasing unit must be used. Because extinguishing nozzles are spring loaded and flush-mounted, they are contamination-free and do not obstruct the material flow.
Not all extraction ducts of the plant are located inside the production building. Sometimes the extinguishing devices are required to be installed outside. Heat tape and insulating material is used to protect water pipes and extinguishing devices from freezing in areas exposed to frost. Special insulating bags are available for the extinguishing devices.

As the price of modern technology continues to fall, aspiring designers are finding it increasingly possible to produce small quantities or even individually designed printed T-shirts.A T-shirt design business can be a part-time venture for an additional source of income. It can also be a full-time career where you’re in charge of your own work, and prosperous work at that.But how do you ensure that your T-shirt design venture is a success? That is what we will be discussing over the course of this article.What Types of T-shirt Printing Are Possible?There are several methods of T-shirt printing to be considered as you evaluate your business strategy. Each has its benefits, and each is preferred for certain circumstances. Choosing the right printing method is absolutely crucial.Heat Transfer printing is arguably the most popular choice for small businesses. The process involves heat transfer to press an existing photo or design on to a fabric. While it certainly isn’t as lasting as other methods, transfer printing is great for small quantities and is much faster than, say, screen printing.Heat transfer provides a smooth feel when the fabric is produced. You’ll certainly notice the difference in texture, but it also has a tendency to crack more often. The machinery required is relatively small and a good option for small scaled production.One of the most important things to remember with transfer printing is the restrictions of pressing on to coloured garments. In general, most forms of transfer printing will focus on white T-shirts. This is due to the problems which arise when you try to press certain colours on to darker garments. Transferring yellow on to a blue garment would traditionally leave a greenish tone, for example.Thankfully, there are now options available which cater for different coloured fabric printing.Vinyl transfers ar
Where do Spark Streams appear?
Spark streams in dust collection systems are a very common danger. They are not easily detected and this means that they may exist but are not known! Consequently, attention is paid to a spark stream only when it is too late, namely when there has been an explosion or a fire.
When working with industrial machinery, sparks are created very quickly. A blunt tool, a damaged bearing in the fan, an overheated motor or foreign body within the material can be the cause.
Sparks are a constant danger in those factories where combustible materials are being worked, exhausted, transported, filtered or dried.
The damage statistics provided by the insurance companies point out that filters, dust collection bins, silos and even complete production lines are the areas of a plant at greatest risk. Foreign bodies in the conveyed material, defective parts of the production machinery, friction processes as well as electrical sparks are all identified as fire generating. Here are the main danger areas known:
- Fiber and Particle Board Industry: The fiber and particle board processing as well as the further processing of the panels by sawing and sanding
- Wood-Working Factories: Working of materials by means of saws, planers, mortisers, hoggers, sanders and other wood working machines
- Chemical Industry: Pneumatic conveyors of dusts and powders
- Foodstuff Industry: e.g. Coffee roasting, tobacco processing and pneumatic conveying of powders
The spark itself is not dangerous. Here’s why: For the creation of fires or explosions there must be three elements that are combined simultaneously: a combustible material, oxygen and an ignition source. Removal of one of the elements will prevent a fire or explosion.
In today’s production plants, we have to cope with all elements that can lead to fire damage or cause an explosion. Extraction systems and pneumatic conveyors increase the danger of fire. Once sparks and glowing embers are created, the pneumatic extraction system conveys this danger very quickly to other subsequent areas of the plant. The danger is when two of the three elements necessary for the creation of fires and explosions are transported, namely: air and ignition sources (sparks).
When this conveyed danger meets combustible materials (filter cloth, deposited and combustible dust in a separator or silo) it becomes more and more likely that a reaction will happen.
Environmental protection measures regarding dust emissions and tightened regulations for air pollution led to an increased use of filter systems, but the danger of dust explosions has not been reduced. In the process of drying, the dryer capacities have been steadily increased so that prevention of fires in these systems has become more important than ever.
What happens after a filter fire? Environmental regulations prohibit plant operation without the filter system. The plant will not only have the cost of repairing the damaged filter system caused by fire but also absorb the extremely high loss of a production shutdown.
According to individual reports, these production losses can exceed the damage costs many times over.
The risk of fire can be efficiently reduced or eliminated by means of modern spark detection and extinguishment systems.
Returned air to the plant also requires spark detection and extinguishment systems. Due to the high amount of material now collected in the dust filter systems, in certain circumstances clean air is allowed to be returned to the production buildings. Enormous savings in heating energy are achieved in this way. A filter fire, however, could quickly be transferred to the production area with devastating consequences.
To protect such a system, all extraction ducts as well as the conveying duct to the material storage should be equipped with spark detection and extinguishment systems.
How can you take Preventive Measures?
Protection can be achieved by installing a modern spark detection and extinguishment system. The sensors detect sparks and glowing embers immediately after their creation. Upon detection and evaluation, countermeasures are induced immediately in order to eliminate the causes of a fire or an explosion.
Let’s compare fire extinguishment systems with spark detection and extinguishment systems. Fire extinguishing systems combat fire after it has come to life, consuming material and air thus producing smoke and damage. A spark detection and extinguishment system eliminates one of the three elements (the ignition source) before it becomes a fire. In this way there is no fire, no smoke, and no damage.
Spark detection and extinguishment systems are able to detect even the smallest of sparks or hot particles in extraction ducts, drop chutes or mechanical conveyors, and to instantly trigger countermeasures. Countermeasures can be: activation of an extinguishing system, diverting the transport path or interrupting the production. All these measures are taken within a split second.
Detection of the ignition source is made by means of spark sensors recognizing the infrared radiation of sparks and glowing particles. These sensitive spark sensors are even capable of detecting sparks through layers of dust or through the conveyed dense material flow. The sensors give alarm signals to the control console, which processes the signals and activates the appropriate countermeasures automatically. Normally an extinguishing device is triggered, which is installed downstream from the spark detectors. This device releases a mist of water in the duct section where the sparks are transported. When no additional sparks are detected, the extinguishment spray is automatically stopped. While the extinguishment takes place, the production process can continue unless otherwise desired. Due to this special operation principle, spark detection and extinguishment systems are classified differently than sprinkler systems, deluge systems, or even explosion suppression systems.
The Control Console
The centerpiece of a spark extinguishing system is the control console.
All signals given by the spark sensors installed in different plant areas are being accumulated and processed by a microprocessor. The extinguishing devices of the affected areas are activated without any delay.
A practical fire protection concept also considers the demand for an almost uninterrupted production. The use of microprocessor technique including the corresponding software results in new possibilities to react on sparks. Integrated counters and time recording systems allow an exact assessment of the spark stream. A graded use of the existing countermeasures is then possible.
For example, single sparks are only extinguished, but for heavy flow of sparks or when single ignition sources are detected over a longer period, further measures like machine shut down of the affected plant sections have to be taken. Diversion of the material transport is also possible using fast-acting abort gates.
The microelectronics has many other advantages.
Ease of Operation
Where once little lamps indicated a flow of sparks, the trouble message is now displayed in clear text. Important functions and all alarms are displayed clearly. The buttons on the keypad light up and provide visual information.
Integrated Memory
Thousands of events are stored so that important information is not lost. This enables analysis of alarms at any time:
- When exactly did the spark stream happen?
- How heavy was the spark stream?
- How long did the extinguishment action last?
- Where exactly did the spark stream appear?
- When was the system out of action?
- When and where did troubles appear?
Automatic Function Checks
To ensure cables are functioning correctly, they are constantly checked for open and short circuit conditions. In addition, spark sensor function tests are performed regularly and automatically. Extinguishing device function tests can be performed manually from the control console.
The Spark Detector
The most important component of a spark detection and extinguishment system is the spark detector. To suit the different and often very severe applications, three different types of sensors are used. All three sensor types have highly sensitive electronics which detect even the smallest of glowing particles.
Spark Detector FM 1/8
The FM 1/8 detector features reliable function even in very dense material flow or when a dust layer covers the optical element. It can be used at material temperatures up to 149°F (65°C), which corresponds to a temperature range of extraction systems for woodworking machines like saws, planers, sanding machines, etc.

Fundraising activities are gaining a lot of importance, as they aid support groups carry out their welfare and development programs. There are day care centers and old age homes that need funds to meet various requirements and hospitals need funds for new and advanced equipments. Thinking of new and innovative fundraising ideas every day that will prove to be successful is an interesting and creative job.In some cases, people who are reluctant to donate cash may be willing to donate items. Donation of items in place of cash is often a relief to the donor and also gives them the option of donating a variety of things. There are many fundraising ideas that can be used to hold sales based on the items collected by way of donation. A toy drive can be held that can give the organization toys to sell to support their program. Organizing a garden sale is also a good idea. It can be organized with some volunteers, who can grow some plant cuttings that would be ready for a plant sale in spring or early summer, when the general public is looking to restock their garden after winter. Book sales are an excellent idea, as they are always well attended. To make this program a success, the fundraising organization requires to collect a lot of donated books. The organization may also approach local publishers to see if they have any books that they could donate to support the program. If they do donate some books, they may highly appreciate it if they are thanked and they are more likely to support the fundraising organization in the future.There are some people who are able to donate their time in lieu than funds. Whether the donation is in the form of money, items, or time, as long it aids the fundraising organization, it should be accepted and appreciated, and these people should be told how much they have helped so they continue to aid the organization in any way they can.

Doing business in the 21st century is entirely different than what it was twenty years ago. At that time computers were not a routine part of small business and it was extremely costly to get started in business. If you are thinking of setting up a brick and mortar business, then the costs have escalated in the past two decades, but it is extremely cost effective to start your own online business.The way you pay for things that you buy has also changed. Now you don't have to carry large amounts of cash because you can use your debit card and have the funds come out of your bank account automatically. Even paying your bills has become easier with online banking and you can go shopping at any time of the day or not when you shop online. Because of this more businesses than ever before are hiring webmasters to set up and manage their websites so that they can deal with customers from all over the world. Now you can do business with a company in Chile, Scotland or the business just down the street with the click of your mouse.The fact that customers can use the power of the Internet to search out the cheapest prices of the goods they want to buy has also made doing business in the 21st century more competitive. Business owners have to keep their prices down as much as possible in order to compete. This has led to a downturn in the availability of jobs, unless you have a skill that is in demand. It is possible to have a business of your own without having an actual store where customers can shop. All you need is an online catalogue for customers to browse through. You can use a part of your basement as your warehouse and ship out the items as they are ordered. You don't even have to wait for payment because you can take the credit card information online. Doing business has never been easier.

Most of us small business owners don’t have the luxury of having a secretary or office manager to screen our calls for us. It can become overwhelming when answering sales call after sales call from telemarketers prevent us from doing what makes us money. To top it off, we can sometimes be talked into spending our hard earned money on products or services that are often overpriced and/or not needed in the first place.Each time we add a new business telephone number or change the business location of the ones we currently have, our telephone numbers are placed on a telemarketing list as a “new business.” Our business phone lines are then overrun by harassing telemarketers that want to be the first to sell a new business what they don’t need. You see a “new business owner” generally hasn’t fine tuned their decision making skills to the point that they can just say no and hang up. These skills come with time and experience. Telemarketers know this and target these new business owners because seasoned owners won’t fall for their tactics.I am always adding or changing toll free and regular phone numbers. To prevent this constant barrage of calls (I call it “the first wave”) or to at least limit them, I have developed a strategy that is working right now. You, as a small business owner, can take what you need from this and add to it your own ideas that you have found that work.First, the “Do Not Call” list! This list was set up for consumers and not businesses. We as consumers are afforded a lot more rights under the law than we are as business owners. Either way there is no mechanism the government can use to determine whether the number you put on the list is a business number or a residential number. I am not telling you to put your company’s number on the list. I am simply explaining that if you did, it would work. Any number that is put on this list almost instantly sees a drop in calls

The thermo sensor TM 1/8 is used for the additional inspection of large areas, like filter and silo systems. Its task is to monitor these areas for self-ignition of the material being conveyed or stored.
The Extinguishing Device
Water is the best extinguishing agent. Its excellent extinguishing efficiency mainly results from the high ability of heat absorption. For this reason it has a strong cooling effect that prevents re-ignition of the combustible materials.
To obtain an optimal extinguishing efficiency, the area covered by the water must be kept as big as possible. This is accomplished by a fine atomization of the water. Atomization is achieved through a special nozzle and sufficient operating water pressure. With high atomization, the amount of extinguishing water can be minimized so that filter elements are not damaged by an excessive amount of water. This allows production to continue while extinguishing takes place.
The operating pressure of the extinguishing device should be at least 60 PSI at a flow rate of 24 GPM per nozzle. If this pressure is not available, a pressure-increasing unit must be used. Because extinguishing nozzles are spring loaded and flush-mounted, they are contamination-free and do not obstruct the material flow.
Not all extraction ducts of the plant are located inside the production building. Sometimes the extinguishing devices are required to be installed outside. Heat tape and insulating material is used to protect water pipes and extinguishing devices from freezing in areas exposed to frost. Special insulating bags are available for the extinguishing devices.

Spark Detector FM 3/8
The FM 3/8 detector is used in applications with operating temperatures above 149°F (65°C) as can appear in drying processes, for example. Spark radiation is carried through fiber optic cables to the detector.
Daylight Spark Detector DLD 1/8
For the most reliable detection of glowing or hot particles, no ambient light can be present at the sensor location. However, where an absolute dark surrounding cannot be guaranteed, sensors that aren’t sensitive to daylight or ambient light are used. These sensors operate only in the infrared spectrum of light so they can be installed at open transfer points or on conveyor belts.

Heat tape and insulating material is used to protect water pipes and extinguishing devices from freezing in areas exposed to frost. Special insulating bags are available for the extinguishing devices.
Alternatives to Extinguishing Means
In some production and processing systems, water cannot be used as an extinguishing means because it would have too much influence on the subsequent process. This is particularly true for the food industry where extremely high accuracy in respect to the material’s moisture must be observed. There are also other industries where water is not allowed as an extinguishing agent. There are alternatives: Diversion gates, shut-off gates, fire traps and even the actuation of a C02 or other inert gas system.
Diversion Gates, Shut-off Gates, Fire Traps.
In these industries, diversion gates to abort the material flow or shut-off gates and fire traps to stop the material flow are used. When the spark sensor detects a spark, or when the preset spark threshold is exceeded, the installed device is activated from the control console.
CO2 Extinguishment
If parts of the plant, complete machines or sensitive filter systems are to be extinguished, a C02 system can be activated by a spark detection system. For this application, spark sensors monitor the ducts leading to these areas. Upon detection of sparks, an alarm message is transferred to the CO2 system through voltage-free relays of the control console. The corresponding parts of the system are simultaneously shut-off by activating shut-off gates so that the incoming CO2 can now flood the contained area.
Central Visualization Software
Events recorded by several consoles that are installed in different areas of the plant are accessible through the visualization software. Such an application offers many advantages: Central actuation and processing of all spark alarms on one monitor is possible. The central acquisition of all events provides the operator with meaningful and comparable data. The remote control of the individual spark extinguishing systems make it possible to react rapidly on each alarm event and allows time and cost savings and shorter production interruptions.
Spark Detection and Extinguishing Systems Insurance Premium Rates
Fire insurance companies have acknowledged the minimized risk when automatic spark detection and extinguishment systems are installed, and may grant discounts on insurance premiums. Precondition for achieving discounts on premium rates is the use of an extinguishment system that is approved by a commercial and industrial property insurance and risk management organization. Factory Mutual is one such organization and the only North American organization to test spark detection and extinguishment systems. Factory Mutual requires stringent manufacturing standards and technical reliability that not only applies to the system, but also to the planning, installation and after-sales service.
Conclusion
Spark detection and extinguishing systems are among the most efficient fire prevention systems, which is a result of their highly developed technique and reliability. The use of these systems for various applications is even prescribed by Factory Mutual. All these factors lead to considerable investment reductions and improved safety for your plant, people and production.
