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.
We 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.

As of 2016, the Department of Justice and the Department of Labor (which includes OSHA) partnered to bring federal charges against companies who expose workers to dangerous materials and carcinogens. Hazardous fume and dust exposure in the workplace is indeed a serious offense.
Environmental Protection Laws Facilitate Prosecution
This partnership is intended to let prosecutors use powerful environmental protection laws to prosecute companies for worker safety violations involving exposure to dangerous substances. This will allow prosecutors working on OSHA worker exposure cases to work with the Environmental Crimes Section of the Department of Justice to maximize penalties and criminal charges.
In many cases, environmental protection laws are stricter and have stronger punishments than OSHA regulations. Environmental protection has wide public support and considerably more funding than occupational health and safety. There is an entire division of the Department of Justice that handles environmental crimes, and these may carry a much heavier fine or more serious criminal charges.
OSHA’s ability to level criminal charges is usually limited to situations where an employer willfully and knowingly violated safety standards and caused the death of a worker. These cases can be difficult to prove and even more difficult to prosecute. Under the laws regulating environmental crimes, releasing or failing to control any workplace hazard exposure to dangerous substances can be considered a crime, even if the exposure does not result in death or serious injury.
Just like with OSHA fines, the most serious criminal charges will go to employers who repeatedly violate the rules or who fail to correct problems even when they know about them. Bringing in the Department of Justice and their regulation of environmental laws is likely to affect companies who aren’t following the rules for controlling or cleaning up their hazardous materials.
Identifying Hazardous Fume and Dust in the Workplace
Workplace hazard exposure includes materials such as fumes and dust from many types of industrial processes. Some examples are welding, plasma or laser cutting, manufacturing of plastics and resins, printing inks and pigments, as well as production of chemicals or fertilizers.
OSHA usually sets exposure limits for employees. Environmental regulations set limits for how much of a material can be released into the environment, regardless of the exposure to individual employees. Under the Department of Justice, hazardous materials being released inside a facility can be handled under environmental laws.
For metalworking facilities, hexavalent chromium, manganese, and other components of cutting and welding fumes are heavily regulated as environmental toxins. Exposing people to these materials, inside or outside, can be an environmental crime. Hexavalent chromium often contaminates drinking water, and it’s a major environmental concern.
For any company that either uses or produces hazardous dust or fumes, a dust collection system is very important for limiting exposure. The system will not only keep the materials away from workers but also collects them safely and allows you to dispose of them properly. A dust and fume collection system that’s maintained and used correctly is a necessary tool for controlling hazardous airborne particles or fumes. Contact us for more information.
HOW YOUR DUST COLLECTOR CAN PAY FOR ITSELF
Installing a dust collection system (or updating an old one) is a big investment. Safety, health, and compliance are all important reasons to do so. Will energy cost savings with this investment benefit your company in the long run? When a company is looking at spending that kind of money, it helps to be able to talk about a more immediate return on your investment.
The good news is that your new system can pay for itself in as little as two years by saving you a lot of money on heating and cooling costs.
It’s hard to put a dollar amount on employee health, but it’s easy to put a dollar amount on how much you spend heating and cooling your building. If you’re spending that money and then venting heated air outside the building, you’re effectively blowing money out the window.
Many of our CMAXX systems have paid for themselves within two years just in energy cost savings. And they will continue to save their owners money for many years of service. Some companies have even been able to find energy conservation incentives that save them money on the immediate cost of a system.
Recirculating air back into the facility can be an excellent cost-saving measure, but only if it doesn’t compromise the health of people working there. This means that the recirculated air has to be completely clean and safe.
If you’re planning to recirculate air, it’s important to make sure that your system is equipped to handle the type of dust you’re producing. Particles from welding fumes and laser or plasma cutting smoke can be as small as half a micron. This usually requires a filter with a rating of at least MERV 15, meaning it is more than 95% effective for particles down to 0.3 microns. If there might be dangerous or highly regulated materials (such as hexavalent chromium) in the dust, a HEPA filter may be necessary for air that’s going to be returned inside.
Besides the savings on energy costs, a system that recirculates air can actually be more efficient. In some ambient systems, the clean air enters at the level where people are working, which moves the dirty air out of the work area and toward the collector. These types of systems are very effective at filtering the air in larger spaces.
If a dust and fume collector is something you’re going to need anyway, the tremendous savings in your energy cost might be what it takes to get that project into the budget. After all, those heating and cooling cost savings will go back into the budget year after year, and that’s something everyone likes to hear.
Weld Smoke and Fume Dangers
Weld smoke is a direct cause of Pneumosiderosis, also known as welder’s lung. Inhaling iron dust or fumes, usually from welding, is a serious health issue. While it’s one of the most common lung diseases of welders, it’s not the only one. Welders are also at risk of chronic bronchitis and cancer. Fortunately, a properly designed dust and fume collector, like our CMAXX™, can prevent these problems.
A case study from the publication Cases Journal gives an example of how welder’s lung can occur. It follows the case of a 64-year-old man who went to his doctor with a cough. He had worked as a welder in an automobile factory for 15 years, welding steel frames. The work area was small and enclosed, without a proper dust collection system to remove weld smoke and fumes.
The man’s doctor found that his lung X-ray was abnormal. Tests showed that his lungs contained many white blood cells full of iron. White blood cells remove things from your lungs that don’t belong there, but large amounts of inhaled iron are too much for them to handle. This buildup of iron causes coughing, shortness of breath, and eventually chronic lung disease.
The man was advised to stop working as a welder. His doctor treated him for his symptoms, and after some time his lung function returned to normal. However, he remains at an increased risk of lung cancer as a result of his long exposure to hexavalent chromium present in the steel.
Along with welder’s lung, inhaled welding dust or fumes also causes an increased risk of cancer. Hexavalent chromium, found in the steel the man in the case study worked on, is a known carcinogen, and welding, in general, has been associated with increased cancer risk.
How Do You Prevent These Risks?
Because the fumes and smoke from welding contain iron and other metals in very, very small particles, these are easily inhaled deep into the lungs. Because these particles are so small, our DeltaMAXX™ nanofiber filters are efficient at removing dust as small as .3 microns, making them an excellent choice for welding and other metalworking applications.
While pneumosiderosis most often affects welders because they are usually very close to the materials they’re working with, the same problem can affect people who are exposed to fumes from laser or plasma cutting. Dust from these applications also may contain hexavalent chromium and other health hazards. Our CMAXX™ system for cutting tables can remove fumes from the air before employees are exposed to them.
The most basic way to prevent welder’s lung is to remove weld smoke and fumes from the air that welders are breathing. A dust and fume collection system like the CMAXX™ can be designed to capture fumes from individual welding stations or from the ambient air. Our systems work with you to keep welders safe and healthy. Learn more about welding fumes and cancer.
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. 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.
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 vent panels, 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 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. 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.
