If you\u2019ve ever walked through an industrial facility\u2014whether it\u2019s a chemical processing plant, an oil refinery, a grain elevator, or a pharmaceutical manufacturing line\u2014you\u2019ve probably seen a small, unassuming box mounted on a wall or beside a motor: that\u2019s a starter and driver. For nearly two decades, I\u2019ve sold these components. Most people I talk to at industry events assume starters and drivers are just routine parts of any motor system, used to turn pumps, conveyors, and compressors on and off without much fanfare. But last quarter, a plant manager in the Gulf Coast called me in a panic. \u201cOur current starters keep tripping unexpectedly in our hydrogen storage unit,\u201d he said. \u201cWe had three unplanned shutdowns in two months, and our insurance is threatening to raise premiums if we don\u2019t fix it.\u201d That call opened my eyes to a question I get more now than ever: Can starters and drivers be safely used in hazardous environments? The short answer is yes\u2014but not all starters and drivers are created equal, and cutting corners on specification, certification, or installation can turn a routine component into a major safety risk. Let\u2019s break this down. Starters & Drivers<\/a><\/p>\n

<\/p>\n

First, we need to define what a \u201chazardous environment\u201d actually means, because that term covers a huge range of industrial spaces. The International Electrotechnical Commission (IEC) and the National Electrical Manufacturers Association (NEMA) classify these environments by the presence of flammable gases, vapors, dust, or fibers that could ignite if exposed to an arc, spark, or overheated surface from an electrical component. For example, a petrochemical plant\u2019s offloading area has explosive gasoline vapors; a grain handling facility has fine wheat dust that ignites at temperatures as low as 420\u00b0F; a pharmaceutical lab might handle flammable solvents like ethanol or acetone. Each of these poses a unique risk, and a standard off-the-shelf starter or driver won\u2019t stand up to them.<\/p>\n

Let\u2019s start with the biggest mistake I see suppliers and plant operators make: assuming any \u201cenclosed\u201d starter is hazardous-rated. A standard NEMA 1 enclosure, for example, is just a simple metal box that keeps dust out of the motor room. It\u2019s not designed to contain an internal spark or prevent one from igniting surrounding flammables. In a hazardous area, the enclosure has to do two things: either it prevents any spark, heat, or arc from escaping into the environment (called \u201cexplosionproof\u201d), or it keeps flammable materials from entering the enclosure at all (\u201chermetically sealed\u201d). For my part, we only source and sell starters and drivers that are third-party certified to IECEx, ATEX, or NEC (National Electrical Code) standards\u2014these aren\u2019t just labels; they mean the component has been tested to survive an internal explosion without rupturing, and that any external surfaces won\u2019t reach a temperature high enough to ignite nearby materials.<\/p>\n

Take the Gulf Coast hydrogen plant I mentioned earlier. Hydrogen has the widest flammable range of any common industrial gas: between 4% and 75% concentration in air. That means even a tiny leak can create a mix that will ignite from a spark as small as static electricity. The plant\u2019s old starters were NEMA 12-rated, which is designed for non-hazardous areas with oily mist or dust\u2014great for a warehouse, terrible for a space where hydrogen is stored. When their old starter\u2019s contactors turned on, the small arc inside the box wasn\u2019t contained, and it ignited a pocket of hydrogen that had seeped past a faulty seal. By switching to our ATEX\/IECEx-certified explosionproof starters for Class I, Division 1 areas (the strictest classification for locations where flammable gases are present 24\/7), they cut unplanned shutdowns to zero in the three months since installation. That\u2019s not luck\u2014that\u2019s design for hazardous conditions.<\/p>\n

Next, let\u2019s talk about drivers, which are often overlooked in hazardous environments. Starters are the basic components that turn a motor on and off, but drivers are the more advanced units that control motor speed, torque, and power. In industries like mining or chemical production, variable frequency drives (VFDs) are used to adjust pump speeds to match process needs, reducing energy use and wear on equipment. But VFDs generate more heat and electrical noise than basic starters, which makes them a higher risk in hazardous spaces. Overheating from a poorly ventilated VFD can ignite dust or gas, and electrical noise can interfere with other safety systems like gas detectors.<\/p>\n

A coal mine operator in West Virginia reached out to me two years ago, saying their VFD drivers kept triggering mine\u2019s dust monitoring alarms. The fine coal dust in the mine\u2019s conveyor tunnel is a Category G hazardous dust, and the mine\u2019s NEC Class II, Division 1 regulations require all electrical components to limit surface temperatures to 320\u00b0F, a threshold well below the ignition point of coal dust. The mine\u2019s original VFD wasn\u2019t rated for dust, so it was overheating at peak conveyor speeds, pushing its surface temperature to 380\u00b0F. We worked with their engineering team to swap the unrated VFD for our dust-ignition-proof driver, which has a sealed internal cooling system that prevents coal dust from entering and a thermal management module that keeps surface temperatures at 280\u00b0F even at full load. That not only resolved the temperature issue but also reduced the mine\u2019s energy costs by 18% because the driver adjusts speed to match conveyor load. It\u2019s a win for safety and efficiency, but only because we matched the driver\u2019s rating to the specific hazardous environment\u2019s requirements.<\/p>\n

Certification isn\u2019t the only piece, though. Installation and maintenance are just as critical, and that\u2019s where I\u2019ve seen even certified components fail. A food processing plant that handles flour dust called me last year, saying their explosionproof starter had caught fire after six months of use. When we did an on-site audit, we found the plant\u2019s electrician had mounted the starter directly above a flour spillage point and hadn\u2019t tightened the enclosure\u2019s seal bolts to the manufacturer\u2019s specification. Flour dust had seeped into the enclosure, and when the starter\u2019s contacts arced, the dust inside ignited. The starter was certified, but improper installation and maintenance created a hazard that should have been avoidable.<\/p>\n

That\u2019s why our company doesn\u2019t just sell components\u2014we provide free site assessments for any hazardous environment project. We send our certified engineers to map the area, identify the specific flammable materials present, and confirm the IECEx or NEC classification of the space (it\u2019s divided into Zones, Divisions, and Classes, which many plant operators don\u2019t fully understand). For example, a Zone 1 area (where flammable gases are present occasionally during normal operation) requires a different rating than a Zone 0 area (where gases are present continuously). A driver certified for Zone 1 will work in Zone 2, but using a Zone 0 driver in a Zone 1 area is overkill and more expensive, while using a Zone 1 driver in a Zone 0 area is a safety risk. We also provide training for plant maintenance teams on how to inspect seal bolts, test thermal sensors, and replace worn components\u2014because even the best certified starter won\u2019t stay safe if it\u2019s not maintained correctly.<\/p>\n

Another common misconception is that hazardous-rated starters and drivers are significantly more expensive than standard units. While they do cost 20-30% more upfront, the long-term savings far outweigh that. Unplanned shutdowns in hazardous areas can cost a plant tens of thousands of dollars per hour, plus insurance premium increases and potential fines for safety violations. The hydrogen plant I worked with saved over $120,000 in lost production in the first three months after switching to our certified starters, and their insurance premium dropped by 15% because of the reduced safety risk. For the coal mine, the avoided shutdowns were even more critical\u2014mining operations can lose upwards of $50,000 per day when a conveyor system is down, and a fire or explosion would have been catastrophic.<\/p>\n

There are also emerging technologies making hazardous environments even safer. I\u2019ve been following the development of intrinsic safety (IS) for starters and drivers, a certification that means the component generates no more electrical energy than is safe to prevent ignition, even if there\u2019s a fault. Unlike explosionproof units, IS components don\u2019t need heavy, bulky enclosures, which makes them ideal for small, portable equipment used in hazardous areas like utility inspection or refinery maintenance. Last year, we rolled out a line of IS-rated portable starters for gas leak detection vehicles, and a number of energy companies have adopted them because they\u2019re lightweight and meet the strictest IECEx Zone 0 requirements. That\u2019s a game-changer for mobile equipment, which has long been a weak point in hazardous area safety.<\/p>\n

Of course, no solution is one-size-fits-all. Every hazardous environment has unique risks, and that\u2019s why our approach is tailored to each client. I once worked with a pharmaceutical manufacturer that handled both flammable solvents and explosive medical powder. They needed a starter that could handle two different hazardous zones in the same facility, so we worked with our manufacturing partner to customize a unit that was IS-rated for the solvent storage area and explosionproof for the powder processing line. That kind of customization is only possible when you partner with a supplier that has deep knowledge of hazardous environment standards, not just a catalog of pre-certified parts.<\/p>\n

I\u2019ll be the first to admit that there\u2019s still work to be done. Many plant operators still don\u2019t understand the difference between a standard enclosure and a hazardous-rated component, and some suppliers cut corners to offer lower-priced \u201chazardous\u201d parts that don\u2019t meet certification requirements. That\u2019s why transparency is so important to our business\u2014we never sell a component without providing full certification documentation, and we\u2019ll never push a client to buy a part that isn\u2019t right for their specific environment.<\/p>\n

<\/p>\n

At the end of the day, the question \u201cCan starters and drivers be used in hazardous environments?\u201d has a clear answer: yes, but only if they\u2019re properly certified, specified to the exact risks of the environment, installed correctly, and maintained regularly. For over 15 years, our company has specialized in partnering with industrial operators to provide the right starters and drivers for their hazardous spaces, balancing safety, performance, and cost. If you\u2019re working on a project in a hazardous environment and you\u2019re not sure if your current starters or drivers are up to code, or if you\u2019re looking to upgrade your system to reduce safety risks and unplanned downtime, we encourage you to reach out to our team for a consultation. We can walk through your site\u2019s needs, answer any questions, and help you find a solution that fits.<\/p>\n
