Spark Trap Safety System: Protect your Dust Collector

Extinguish the threat of explosions with a Spark Trap safety system.

While it is imperative that every metalworking facility have highly efficient dust collection systems, it is just as crucial that metalworking facilities utilize a spark trap safety system to provide even greater protection from these combustible hazards.

spark trap safety systemWe have dedicated over a 15 years to preventing and reducing fires and explosions in metalworking and manufacturing facilities. We also continually strive to meet and exceed the standards recommended by the Occupational Safety and Health Administration.  Our company also meets the guidelines set out by the National Fire Protection Association with our highly efficient dust collection systems and replacement cartridge filters.

If you’re asking yourself if a spark trap is really necessary– the answer is yes! Consider the findings of the OSHA’s National Emphasis Program.  It shows that metal dust accounts for 20% of explosions nationwide. Also, 7% of ignition sources are ignited by fabricated metals while another 8% of ignition sources are caused by Primary metals. If you want to reduce the possibility of an accident at your metalworking facility, you MUST invest in spark arrestors!

How Can  Spark Trap Safety Systems Reduce Explosions?

Adding a spark trap to your industrial dust collection system is like adding a security system to your home. You already have the proper amount of protection with locks, but installing a security system in your home provides another line of defense, keeping you and your family safe.

Our spark trap, named Spark Arrestor, is the first line of defense in protecting your metal fabricators and your metalworking facility from explosions.  Spark Arrestors extinguish nearly every spark before it enters into the main containment unit where combustible dust and other flammable material collects. When you choose our Spark Arrestors, you’ll receive a quality product made with heavy duty materials that is highly effective at keeping sparks from entering your industrial dust collector.

Here are some key features you’ll receive when you invest in our spark traps:

Whistleblower Dilemma: Your safety or your job?

Afraid to report unsafe work conditions at your work site?  OSHA can protect you from retaliation.

It is a known fact that many workers are forced to work in unsafe environments.  Although most companies strive to provide safe and healthy working conditions for their employees, there are some places that are unwilling to make worker safety a top priority.  If you know you are in a situation where your safety and others that work with you is at risk, you may have fears of losing your job if you bring it to anyone’s attention.

safety

The stigma of being a Whistleblower is not what it used to be in the past.  In fact, OSHA has a program in place that protects your rights as an employee.  Such provisions include:

  • The right to file a safety complaint to OSHA
  • Protection from employer retaliation, such as termination
  • The right to participate in OSHA inspections and talk to the inspector
  • The right to review employer exposure and/or injury records

OSHA has fined many corporations due to unfounded termination of employees who report safety violations.  It is simply against the law, and in the end, costs the company more than just fixing the safety problem itself.

Keep in mind that sometimes it may not be a malicious intent by your employer.  They may not be aware of safety issues that concern you.  How do you approach this situation?  Read this informative article that gives you tips and advice about talking to superiors with confidence.

All in all, there are many options for shop and factory workers to be part of the solution in making their job safe.  Click on the links below if you have questions or want to learn more about safety in the workplace.

OSHA SCAMS: HOW TO AVOID BEING A VICTIM

OSHA SCAMS: 3 WAYS THE FEAR OF OSHA REGULATIONS TRICKS BUSINESSES OUT OF THEIR MONEY

Most businesses try to make sure they comply with OSHA regulations. They don’t want any accidents or injuries and they don’t want big fines if an OSHA inspector comes through. Some scammers, though, take advantage of the anxiety a business owner or manager may feel if they think they’re out of compliance with the regulations.

osha scams

 

These scam artists use the threat of getting fined as a weapon to scam businesses out of their money. According to the Federal Trade Commission, these companies may use names like “Occupational Safety and Compliance Administration” that are designed to make you think they’re a legitimate government entity. They’re not.

 

The three most popular OSHA scams:

  • BUY POSTERS. This one is the most popular, because almost everyone has seen all the posters that the Department of Labor, OSHA, and other organizations say must be in full view at all times.

All required OSHA posters and other informational materials are FREE. OSHA is a government agency and will not attempt to sell you posters. In addition, beware of people who claim to be offering official OSHA training but don’t have the documentation to back it up.

 

  • BUY KITS. Yes, OSHA does require you to have a first aid kit in your workplace. Does OSHA sell a first aid kit that you must purchase to meet their requirements? No. The same applies to the additional safety kits required in some settings such as health care.

Everything required in a standard first aid kit can be purchased at a drug store. There are no secret items and there is no requirement that the kits be “approved” or “certified” to meet the standards. OSHA does not sell a first aid kit.

 

  • GIVE US MONEY. A fake OSHA inspector will arrive at your business, locate a number of “violations”, and then tell you that you either must pay them right now or that you can negotiate out of the official fine by giving them money up front.

Anyone who shows up, starts “inspecting”, and then tells you that you have to give them money is not an OSHA inspector. Before conducting an inspection, a real OSHA employee will provide you with proper identification and paperwork, explain why they’re there and what they’re going to do, and make a report. They will NEVER ask you for money and they will not offer to let you buy your way out of a fine under the table.

 

These may seem like very silly an obvious scams. But don’t forget that these people are very good at what they do. They use official-sounding language and may have what looks at first glance to be an official identification. They are very good at using persuasion and threats to convince people that if you don’t buy their trainings, posters, or kits, you’ll be out of compliance and be punished for it.

 

The easiest way to make sure you don’t fall for OSHA scams? Keep the number of your local OSHA field office on hand. If someone calls or shows up and insists that they are there to take your money in the name of OSHA, you can always call the real thing and ask them.

Industrial Dust Control Solutions: Why It Matters

Whether you are a new manufacturing business or just branching out into new territory, if you are going to get into the metalworking field, addressing industrial dust control solutions demand some serious consideration. Not only do you have the safety of your work space to think about, but unchecked dust and fumes can also pose health hazards to those working in it. We’ve spent nearly 15 years considering the challenges of industrial dust accumulation and control, and we have developed the solutions our customers need.  Discover the facts you need about dust control for your business to keep things running safely and smoothly.

Meet Safety Standards

industrial dust control solutionsAn accumulation of dust in any industrial setting poses a threat to the health and safety of those working there.  This is especially true in the world of metalworking where the fine dust particles may be especially toxic.  In light of this threat, the Occupational Safety and Health Administration (OSHA) has established standards of safety that must be followed in any such industrial settings.  These address not only dust that may be inhaled but also the threat of combustibility through its accumulation.  Check out the latest combustible dust update HERE.  When you look for an industrial dust control system, begin by ensuring that it meets these and other industry standards.

Anticipate Dust And Fumes

As you consider a system to provide dust control for your work space, make sure you take fumes into account as well.  In many metalworking processes, noxious fumes are created which are more than unpleasant; they can be increasingly harmful when inhaled.  Not all industrial dust control systems are created to handle this dual threat, so it is vital to choose a collector that can manage both dust and fume generated by metalwork manufacturing.

Dust and Fume Collection: Do you need it?

DUST AND FUME COLLECTION:  SOME INDUSTRIES THAT MIGHT NOT KNOW THEY NEED IT

Dust and fume collection in a manufacturing facility is important for many reasons.  Here are the top five reasons you should consider:

 

Top 5 reasons you need dust and fume collection

NOT CONVINCED YET?

Can you name the metal that causes cancer, damages skin, eyes, lungs, and kidneys, and is found in everything from stainless steel to dyes and pigments?

 

If you said this compound is HEXAVALENT CHROMIUM (https://www.osha.gov/SLTC/hexavalentchromium/) you’re right.

 

Chromium is a component of stainless steel, added to make the steel more corrosion-resistant. The fumes produced from welding, laser cutting, or plasma cutting stainless steel contain hexavalent chromium. While this form of chromium is known to cause cancer, it also directly attacks the lungs and kidneys and can cause severe eye and skin irritation.

Hexavalent chromium doesn’t just appear in welded or heated stainless steel. Electroplating with chrome also presents a hazard, and hexavalent chromium compounds are used as pigments in inks, paints, and many types of plastic. Working on any material plated with chrome or coated with a chromium-containing material may release hexavalent chromium into the air.

Think hexavalent chromium isn’t something to worry about in your type of business? You may need to reconsider. OSHA TESTING (OSHA TESTING: https://www.osha.gov/SLTC/hexavalentchromium/) showed which types of facilities had detectable levels of this dangerous metal in their air. The following are some of the top offenders:

  • Nonresidential building
  • Highway, street, and bridge
  • Foundation and structural materials
  • Foundries
  • Forging and stamping
  • Architectural and structural metals
  • Boiler, tank, and container
  • Coating
  • Engraving
  • Heat-treating
  • Agricultural machinery
  • Mining machinery
  • Ventilation and air-conditioning
  • Aerospace products and parts
  • Ship and boat building
  • Automotive repair and maintenance

Dust Explosions: The Hidden Hazard

Dust explosions are bad to begin with, but what do you know about secondary explosions?  There are many factors that determine how likely a particular type of dust causes a deflagration. When you think of combustible dust, do you think of the explosions you’ve heard about at grain handling facilities? Maybe you think of the explosive potential of aluminum dust.

 

Three dust explosions that occurred in 2003 demonstrate how many different types of production and manufacturing can produce a deflagration risk (http://www.fireworld.com/Archives/tabid/93/articleType/ArticleView/articleId/86899/DEADLY-DUST.aspx). In a North Carolina plant, the accumulated dust came from a polyethylene coating being applied to rubber. As the material dried, dust was formed and accumulated above the work area. Even though the work area itself was very clean, a layer of dust a quarter of an inch thick was enough to cause an explosion that killed six people. In this situation, a dust collection system in the production area could have captured the dust particles as they came off the material, before they were allowed to circulate through the facility.

dust explosions

The explosion in Kentucky was caused by combustible dust that resulted from a resin used to treat fiberglass. Workers were aware of the large quantities of dust, but cleaning processes often just caused more of the dust to become airborne, and it accumulated in the ductwork and in dust collection equipment. There were no safeguards in place to prevent a flame front from traveling through the ductwork or getting into the dust collector. An abort gate with spark or flame detection could have identified and stopped the fire from spreading, and dust collectors designed to stop deflagration fronts could have prevented the dust collectors from becoming sites of secondary explosions.

 

The explosion in Indiana was fueled by aluminum dust from scrap processing. The dust collector in this case was the source of the explosion. It did not have explosion venting, and instead of being directed safely, the explosion traveled back into the building and ignited dust in the ductwork. A secondary explosion occurred when dust accumulated on surfaces inside the facility ignited. A dust collector designed to isolate and redirect a deflagration could have prevented this accident.

 

The National Fire Protection Association, which establishes many of the codes and standards for handling potential fire hazards (http://www.nfpa.org/codes-and-standards/all-codes-and-standards/list-of-codes-and-standards) recommends that all dust collection systems should have explosion venting to redirect explosions and abort gates or other equipment to stop flame fronts from spreading. It also recommends improved housekeeping measures to prevent dust from accumulating, which may be accomplished by collecting dust at the source so it cannot accumulate in difficult-to-reach places.

 

It’s often this accumulated dust, hidden on high surfaces, in corners, or inside ductwork, that ignites to cause a secondary explosion that’s far more dangerous than the original one. Witness reports of dust explosions often include descriptions of a smaller explosion followed by one or more larger ones; this is secondary ignition (https://www.osha.gov/Publications/osha3791.pdf). Dust control throughout the entire facility, along with fire prevention equipment such as abort gates, spark arrestors, and explosion venting, can control a potential explosion and prevent a small fire from becoming a fatal disaster.

Wet Dust Collector Vs. Dry?

Since we manufacture dust control systems that use filters (bags or cartridges) to collect and control dust, we obviously have a preference for dry systems.  But what about a wet dust collector? Both wet and dry systems have their advantages and disadvantages. Many of them depend on your process, the type of dust you produce, and your individual needs. Baghouse and cartridge filter dust collectors have worked safely and efficiently for many years and in many different applications.  However, as concern and awareness of combustible dust issues grows, some companies are considering a wet system that “scrubs” the air stream with water for dust control. Read on for some points to think about:

 

THINGS TO CONSIDER:

  • Type of dust

Wet dust collector systems are often used where there is a concern about combustible dust, especially metal dust, combined with a high likelihood of sparks coming into contact with the dust. Dry systems can also be used in this application.  Although, if there is a risk of deflagration, the system should include safety devices such as spark traps, and fire-retardant filters that will not fuel a fire. Our DeltaMAXXTM nanofiber fire-retardant filters are rated to safely control a deflagration inside the collector. Wet systems decrease the risk of fire or explosion because the air travelling through the collector is cleaned by “scrubbing” it with water before allowing the dust to settle out. This ensures that even if there is an ignition source, there’s no dust cloud or dry dust to ignite. On the other hand, dry collectors with proper maintenance and housekeeping have been used safely for many years with almost every type of dust imaginable.

 

  • Particulate Size

The filters in dry systems are more efficient at collecting and removing very fine particulate, with nanofiber filters 99.9% efficient in capturing particulate down to .3 microns. While some cutting and grinding may produce larger particulate, applications like welding, plasma and laser cutting, and other processes produce very fine particulate metal fumes that are more efficiently captured by a dry collector system. In a wet system, it may be difficult to get very small particulate to settle out of the water so it can be collected, although some wet systems are designed to handle this. Overall, a dry collector is more efficient for smaller particulate, smoke, and welding fumes.

 

  • System Setup

A wet dust collector is often used on individual work stations such as downdraft tables. When a central dust collection system is used, the requirements for ductwork and proper CFM throughout the system may be similar for wet and dry types. Because a dry system is more efficient at capturing smaller particles and fumes, these types of systems are often used where there are multiple locations in a facility producing welding or cutting fumes. Since dry systems are more effective in collecting smoke and fumes, they may be able to operate at a lower CFM, which saves energy and decreases the noise produced by the system. A wet collector is often used on equipment like a downdraft table where sparks and metal dust are in close proximity, although many downdraft tables use a dry collector because they produce small particulate, smoke, or fumes. A full assessment of your company’s needs will help determine which type of system would be most beneficial for you both for safety purposes and in long-term operating and maintenance costs.

 

  • Maintenance and Disposal

Depending on your type of dust, there may be regulations for how your material needs to be disposed of. With a dry system, bags or cartridge filters usually filter the dust into a container for disposal. With a wet system, the accumulated dust settles out of the water and the sludge must be collected and disposed of. Since the sludge will eventually dry, it is often mixed with an inert substance like sand to make it safer to handle. Many waste management facilities have different regulations for dry and wet materials.

 

To make a wet collector efficient at removing smaller particles, the system requires higher water pressure and a lot of energy, which increases the cost. For larger particles, the energy costs are lower because it is easier to get these particles to drop out the air stream. A dry collector requires compressed air to periodically clean the filters, and the frequency of pulsing can be adjusted to suit individual needs, and can be decreased by the use of filter media like DeltaMAXX nanofiber that pulse-clean more efficiently. Both types of systems require appropriate equipment to maintain the correct air flow.

 

Maintaining a dry dust control system usually means changing the filters regularly and monitoring differential pressure. The filters will contain dust and must to be disposed of according to the standards for that material, and the collected dust must also be disposed.  Maintaining a wet dust collector system includes making sure the water remains clean, without too much material dissolved in it, and disposing of contaminated wastewater. Removal and disposal of sludge is required for a wet collector, and the sludge may need to be mixed with other materials or dried to make it safer or more easily disposable. Both types of systems will require proper housekeeping and maintenance of the ductwork and work areas to make sure dust doesn’t accumulate.

Combustible Dust Standard: A Stalemate

STALEMATE BETWEEN FEDERAL AGENCIES MAY BE MOVING TOWARD RESOLUTION

A combustible dust standard may mean more stringent control measures, a lot of new tests and reports, and major growth in the air quality control industry, especially dust collection systems.

Since 2008, the National Fire Protection Association (NFPA) and the U.S. Chemical Safety Board (CSB) have been making recommendations to OSHA that a formal standard for combustible dust is needed to prevent worker injuries and deaths caused by dust explosions. OSHA established a “National Emphasis Program” to provide more information and awareness about dust control and combustible dust hazards. They have yet to establish any formal, enforceable standards. The CSB continues to make recommendations for such a standard in their investigations of explosions and resulting fatalities (http://www.csb.gov/us-chemical-safety-board-determines-osha-response-to-seven-open-csb-recommendations-on-dust-fuel-gas-and-process-safety-management-to-be-unacceptable/) and has deemed OSHA’s response to their recommendations to be “unacceptable”. They consider an OSHA combustible dust standard to be the most important safety measure they have recommended.

According to John S. Forester, the managing editor at Powder & Bulk Solids, (http://www.powderbulksolids.com/) the NFPA is currently working on revisions of its standard 652, its proposed standard for combustible dust, intended to be comprehensive and to cover all industries to which it would apply.

This combustible dust standard (https://www.nfpa.org/Assets/files/AboutTheCodes/652/652_PreliminaryDraft.pdf) would require that all facilities, new or existing, complete Dust Hazard Analysis testing and report their results. Also, some of the standards will be applied retroactively to existing businesses. In response, OSHA seems to be responding to the call for increased regulation for the first time since 2010. However, there’s no sign of new enforceable regulations in the immediate future. Facilities who need to meet NFPA standards may find themselves dealing with the mandated Dust Hazard Analysis. This will mean an increased investment in dust control systems.

The article notes that due to increasing regulation and the adoption of NFPA standards globally, the market for industrial dust collectors is expected to increase significantly in the following years. Demands for explosion isolation equipment (such as Imperial Systems independently tested, NFPA-standard CMAXX with In-Line Deflagration Arrester filters) are expected to be even higher as reports of industrial accidents and stricter regulations circulate in the industry.

The NFPA 652 will require industry-wide testing of all dusts that might be combustible and full analysis of all facilities for areas and equipment that might create a risk of dust accumulation, such as conveyor belts, elevators, ductwork, and ovens. Dust testing may include standards on the amount of dust allowed to accumulate on any surface and testing to determine whether the dust is in contact with hot surfaces or static buildup that could trigger ignition of that particular dust. These assessments will be an ongoing headache for many companies, and installing a system of correctly functioning dust collection equipment (and maintaining it or having it maintained by our ServiceMAXX professionals) can minimize that headache by keeping the dust problem minimal and keeping the facility up to standards.

While the expected boom in sales of industrial dust extraction and explosion suppression equipment is good news for our industry, it’s especially good news for Imperial Systems, since our CMAXX with IDA filters already meets NFPA standards and should continue to meet the new standards in the future. If you already have one of our systems and it is well-maintained and operating properly, you should be prepared to weather any new regulations for explosion-containing dust collection systems. If you’re using another type of dust collector, measures such as high-speed abort gates and our fire-retardant DeltaMAXX nanofiber filters can help you be in compliance with current and future standards.

BagHouses: How They Work

Baghouses and Dust Collectors are often used as synonyms. The baghouse is a system in which air is filtered by bags made of various materials, which are periodically cleaned to remove the accumulated dust. Today, cartridge dust collectors are increasingly popular in many industries, and for good reason: cartridge filters can pack a lot of surface area into a small space and can filter very small (sub-micron) particulate very efficiently. For some industries this is essential, particularly for industries such as metalworking that generate smoke and fumes that contain potentially toxic materials.

The baghouse, however, has been a workhorse industrial dust control for many years, and continues to serve its role today. While the basic concept remains the same, new filter materials and new ways to solve problems make them more adaptable than ever. Not every industry produces dust that’s fine enough to need the high efficiency of a cartridge collector.baghouses

Generally, all baghouses have a tube sheet to which the bags are attached, an inlet for dirty air and an outlet for clean air, and an opening at the bottom for collected dust to drop out. The location of these features depends on the type of baghouse. The main differences between types of baghouses is how the bags are kept clean.

In a shaker baghouse, the bags are cleaned by mechanically shaking them. The bags usually hang from the top of the unit and are attached to the tube sheet at the bottom. In this type of system, air typically enters from the bottom.  It is then pulled through to collect on the inside of the bags. Air then exits at the top as clean air while the dust is collected on the inside of the bags. To clean the bags, the airflow must be shut off and the hanging mechanism shakes the bags to get rid of the dust, which drops out the bottom. These are not the most efficient types of baghouses and can be high-maintenance.  Yes, the design is simple and does not require compressed air or complicated supports for the bags, however damage to the bags can occur from the mechanical shaking mechanism.

In a reverse air baghouse like our BRF, dirty air enters the collector and dust collects on the outside of the bags, which are supported by a metal cage to keep the air pressure from collapsing them. Steady air circulation continuously pulls air through the filter bags. For cleaning, a fan rotates over the bags, blowing reverse air into them to remove dust. This type of reverse air baghouse generates a lower pressure than the compressed air pulses of a pulse jet, which can decrease wear and tear on the bags and save on the cost of compressed air. They are usually very cost-efficient and if used within the parameters for which they were designed, they are very effective.

Also, this type of reverse air baghouse can continue running while cleaning occurs. An older type of baghouse also sometimes referred to as reverse air may collect dust on the inside of the bags and then cut off the inflow of dirty air and use a reverse flow of clean air to partially collapse the bags, which also removes the dust. These types of bags have rigid rings that allow them to flex but not collapse completely, or “pancake”. These types of reverse air baghouses have to be taken off line for cleaning or are divided into compartments so one section at a time can be cleaned.

A pulse jet baghouse is somewhat similar. The bags are supported by metal cages and hang from a tube sheet at the top of the baghouse. Dust and air enter and dust collects on the outside surface of the bags, not the inside. The bags are cleaned by bursts or pulses of compressed air that travel down the length of the bag and dislodge the dust. Because the pulse of air travels very quickly down the bags, this type of baghouse can be cleaned without taking it offline. This allows them to operate more efficiently since dust is removed from the bags at more regular intervals. The downside to these types of collectors is the higher pressure and expense of compressed air, which adds to operating costs.

The EPA provides information (link: https://www3.epa.gov/ttncatc1/dir1/cs6ch1.pdf) to help you make a general calculation of the capital costs of a baghouse dust control system. Their calculations include the cost of the collector, the bags (and cages if necessary), measurement instruments, installation costs, and the annual operating costs (electricity, compressed air, labor, and materials). These costs will obviously vary widely. A pulse jet baghouse requires compressed air, which is not needed for the other types of baghouses, but may require fewer filters since they are more efficient.

One thing that is a major headache for owners of any type of baghouse: replacing the bags. This is usually a dirty, messy, time-consuming job that requires the collector to be off-line for a considerable period of time. It often involves working in an enclosed space. Mechanisms for attaching the bags to the tube sheets vary widely, but especially when cages are involved it can be a very involved process. Some companies installing new dust control equipment choose a cartridge filter collector because vertical collectors like our CMAXXTM are easy to change and do not involve issues with confined spaces. For existing baghouses that need frequent bag changes, a pleated filter bag (link to our page) is an option that should be considered. These have a much larger surface area and last much longer than traditional bags, which means less frequent changes. Also, pleated filter bags do not require cages, which greatly simplifies the changing process.
