Is Your Industrial Vacuum Cleaner NFPA 652 Compliant?

As inconspicuous as dust may seem, it can be incredibly hazardous, especially in industrial and commercial facilities. Over that past decade, dust has been one of the leading causes of serious flash fires and explosions in processing facilities. 

The Occupational Safety and Health Administration (OSHA), an agency within the U.S. Department of Labor, has recognized the hazards that dust poses and stresses the need to deal with them appropriately. As a result, the National Fire Protection Agency (NFPA) introduced NFPA 652: the Standard on the Fundamentals of Combustible Dust. 

NFPA 652 has set the standard for dust safety for the processing industry, defining what combustible dust is and how to best manage it to prevent serious safety issues. 


What Is NFPA 652 Compliance? What Does It Mean for Industrial Vacuums?

NFPA 652, Standard on the Fundamentals of Combustible Dust, is a standard that was created to promote and define the hazards of dust, creating awareness and directing facilities on how to properly manage and reduce dust hazards. More specifically, it provides requirements for dust management in facilities where combustible dust fires and explosions can be an issue. 

When necessary, and based upon the industry in question, NFPA 652 also directs facility owners and managers to other NFPA standards, like NFPA 61, NFPA 654, NFPA 484, NFPA 655 and NFPA 664, which are concerned with combustible dust from various commodity-specific industries. 

The foundation of NFPA 652 — and the related standards — focuses on creating a safe environment where combustible dust is concerned. Specifically, this means that the fuel source — dust — is properly managed, ignition sources are controlled, and the potential for explosion is limited through proper facility design, protection, isolation and proper housekeeping. Meeting all NFPA 652 requirements earns facilities NFPA 652 Compliance. 

NFPA 652 Compliance is a recognition given to facilities that have complied with the standard and met all necessary safety rules and requirements. Without meeting these requirements, facilities will fail to earn NFPA 652 Compliance. This can result in steep fines and production being stopped until all non-compliance issues are corrected.

One requirement outlined by NFPA 652 is determining the combustibility and explosivity of various materials within the facility, particularly dust. To do this, you need to conduct a Dust Hazard Analysis (DHA), which is used to identify the specific combustible dust hazards associated with a process. 

Once the DHA has been completed and hazards identified, facility owners and operators must take the proper steps to deal with these hazards and manage the risks posed by combustible dust. From there, owners and operators need to establish a written safety management system that enforces NFPA 652 and explains to employees how to properly handle combustible dust.

The requirements and guidelines above are meant to create safe operating facilities and equipment. By following the guidelines, you minimize the risk of serious combustible dust hazards within the facility. All working parts and equipment within the facility are required to meet these requirements to earn NFPA 652 Compliance. Even industrial vacuums, which are often overlooked, need to meet NFPA 652 compliance.

Why Is It So Important?

According to a 2007 dust hazard study conducted by the U.S. Chemical Safety and Hazard Investigation Board (CSB), there were nearly 280 dust fires and explosions over a 25-year period. These fires and explosions resulted in 119 worker fatalities and over 700 worker injuries. 

The incidents happened in a wide range of industries that produce various types of combustible dust. While good housekeeping is an essential part of preventing dust explosions, proper facility design and engineering is also vital. This includes using the appropriate electrical and ventilation equipment, keeping this equipment in working order and covering pipes, while embedding cables into walls to prevent surface dust.

It is especially important to manage potential ignition sources — anything that can generate flames or sparks or that can create static electricity: one of the key components to combustion. 

There are three main components needed for combustion: the presence of combustible dust, oxygen and a heat source. Two additional components are required for an explosion to occur: the dispersion of dust particles in a sufficient concentration and the confinement of that dust cloud. 

All of this knowledge has led to new safety standards, like NFPA 652, meant to protect structures, people and products from harm. These standards are regulated and enforced by various agencies, including the U.S. Department of Labor, OSHA and the NFPA.

Compliance with these codes, including NFPA 652, is not optional. Failure to comply can lead to severe consequences like the facility being shut down until the standards are met, which can cause significant financial loss. In addition, facilities can be hit with substantial fines for noncompliance, which creates an additional financial burden on facility owners and operators.

Which Industries Require NFPA Certification

NFPA 652 compliance is required by any facility whose processes produce any amount of combustible dust. Major industries that fall into this category include powders, agriculture, food, pharmaceutical, pesticides, rubber, plastic, textiles, chemical, recycling, coal-fired power, wood and more. 

There is a wide range of combustible dust produced by these various facilities, each posing serious risks to safety. Anything from flour dust in the food industry to epoxy dust from the chemical industry is considered dangerous, combustible dust. 

What to Look for in an NFPA 652 Vacuum 

Keeping a facility free from combustible dust is essential. However, doing so requires NFPA 652 compliant equipment, including an approved NFPA 652 vacuum. The standard has seven requirements that industrial vacuums have to meet to be compliant:

  1. Except for certain circumstances, an industrial vacuum should be made using conductive materials.
  2. In addition to a conductive build, the vacuum’s hose should either be conductive or static dissipative.
  3. All the conductive parts of the vacuum must be bonded and grounded.
  4. When working, dust-laden air should not pass through the fan or blower.
  5. For vacuums with electrical motors, the motor should not be in the dust-laden air stream, unless it is listed for Class II, Division I locations.
  6. There should be no paper filter elements in the vacuum for picking up liquids or other wet materials.
  7. In addition to meeting NFPA 652 requirements, vacuums used for metal dust must also meet NFPA 484: Standard for Combustible Metals.

HafcoVac’s NFPA 652-Certified Vacuums

Finding an NFPA 652-compliant vacuum that meets all the necessary requirements can be difficult. Fortunately, there is HafcoVac. 

HafcoVac has been servicing various industrial industries for over 15 years, specializing in NFPA and OSHA-certified industrial vacuums that are made in the USA. They offer explosion- and dust ignition-proof industrial vacuums that are energy-efficient and have variable power.

Industrial Pneumatic Vacuums 

HafcoVac’s industrial pneumatic vacuum is powered by compressed air rather than a motor with moving parts. For that reason, it does not require any electricity to run, which makes it easy to use in any part of the facility. 

HafcoVac’s pneumatic vacuums can handle not only combustible dust waste, but dry and wet material recovery as well. Aside from being NFPA 652 compliant, this vacuum also meets NFPA compliance for standards 664, 484, 70 and 61. 

It has the option of either an anti-static or static conductive hose, per NFPA requirements. These types of hoses help to ensure that any static electricity dissipates, so there is no risk of fire-causing sparks. 

Another benefit to pneumatic vacuums is that they require little maintenance since there are no moving parts that need cleaning. The only maintenance workers would need to be concerned about is changing filters when necessary. 

All of HafcoVac’s Explosion-Proof industrial vacuums come with a High-Efficiency Particulate Air (HEPA) Filtration system. These filters are 99.97% effective at keeping fine dust particles from entering the air, keep workplaces and the air cleaner. 

Areas such as asbestos abatement, lead paint recovery, healthcare facility cleaning and pharmaceutical manufacturing require HEPA filters for their work. Additionally, food processing, mining, power generation and facilities dealing with combustible dust all should use industrial vacuums with HEPA filtration systems.

While it is already an incredibly versatile vacuum that can clean any virtually part of a facility, there are accessories that help make it an even more efficient machine for eliminating combustible dust within a facility.

Ensuring NFPA Compliance

Processing facilities must maintain a safe, dust-free facility. Dust, especially within these facilities, can cause serious safety hazards for the facility, its employees and its products. Combustible dust poses a risk of fires and explosions that can lead to injuries and even death. 

To create a safe facility, you need to follow the OSHA Housekeeping Guidelines and NFPA’s Standards for safety, particularly NFPA 652. This includes using an NFPA 652-compliant vacuum, like those provided by HafcoVac. These are made to those strict standards and are rated for use with combustible dust, even in hazardous environments.

Selecting the Best Vacuums for Powder Coating

Powder coating is the preferred finishing technique for consumer and industrial goods, thanks to its durability, economy and quality.

However, the powder itself may present serious health and safety risks when stored, conveyed and applied to products. Under the right conditions, one such risk is the high possibility of combustible dust explosions. An additional risk associated with improper handling of powder dust includes inhalation of particles by workers. It is crucial to ensure that proper housekeeping procedures are put in place and followed on a regular basis to mitigate these risks.

Due to recent NFPA and OSHA guidelines requiring facilities to perform a comprehensive dust hazard analysis and develop a plan to deal with these risks, manufacturers and factory owners now need specialized tools to meet regulations and minimize these hazards.

HafcoVac’s certified, explosion-proof industrial vacuums present an intrinsically safe solution for powder coating clean up. They offer excellent suction regardless of the dust’s location — whether the paint particles are on overhead beams, machinery, walls or floors.

In this article, we will learn more about powder coating, the potential risks that come with it and how we can help prevent them with Certified HafcoVac vacuums.

What Is Powder Coating?

Powder coating is one of the most in-demand paint application techniques for manufacturers of industrial and consumer appliances. In fact, the appliance industry acquires the largest share of the powder coating market, amounting to two-fifths of all industrial powder coated parts.

The powder coating process involves spraying paint in the form of powder on top of binders and pigments that are sprayed directly onto the surface. In contrast, liquid paint has binders and pigments present in solvent. The inclusion of binders and pigments in liquid paint results in longer drying times, which can also vary depending on atmospheric conditions. 

Once the powder coating spraying is completed, the item must be baked to a certain temperature for a set amount of time. Called curing, the duration of this process is different for different types of powder. Next, the powder is heated to a high temperature in order for the powder to melt. Once melted, the object is cooled for a hard and durable finish. 

Several types of materials including plastics, metals, medium-density fiberboard (MDF) and glass can be powder coated. Similarly, many types of textures and finishes that are not possible with liquid coating methods can be achieved with powder paint.

Here are some advantages of powder coating:

  • More durable compared to liquid coating
  • Better and thicker finish
  • Low environmental impact
  • Less waste
  • Efficient curing and drying process

Risks Associated With Powder Coating

As mentioned, the biggest risks related to powder coating are fire and dust explosions, followed by dust particle inhalation. 

A dust explosion occurs when there is powder accumulation in different parts of a factory or site. If introduced to a source of ignition, it can result in its rapid combustion.

One possible source of ignition is static electricity. This can build up when a vacuum has no grounding to dissipate the static charge generated by the unidirectional flow of the powder debris through the cleaning hose. 

If this ungrounded hose comes in contact with a grounded object, the consequence can be a deadly explosion. That’s why OSHA and the NFPA 654 standard recommend your vacuum: “control static electricity, including bonding of equipment to ground.” 

The rapid combustion of powder coating dust is known to have caused several fires that have resulted in serious damage to the factory and led to pricey shutdowns. As a matter of fact, in 2016 alone, a total of 22 workers were injured and three casualties were recorded due to fire and dust explosions in the U.S. and Canada, combined.

Considering the extent of damage that combustible dust can cause, it is important to use vacuums specially designed to eliminate the risk.

Why Vacuums Are Necessary

With powder coating, the inclusion of an explosion-proof vacuum that can safeguard both workers and the workplace by reducing the possibility of a dust explosion is an essential part of any housekeeping procedure.

As such, it’s important to select a vacuum that is durable and reliable and can efficiently draw up powder from different surfaces. One key element of a vacuum is its filtration system; a good model can clean up powder efficiently without exhausting fine dust into the air. Look for one that has a HEPA filter. 

HEPA filters are 99.8% effective at keeping fine dust particles from entering the air. That results in cleaner air and a cleaner workplace, reducing the explosion risk. HEPA filters are the ideal choice for vacuuming fine dust. 

Many people opt for standard vacuums or Shop-Vacs to pick up powder without realizing that they have limited filtration capacity and motor quality. As such, they do more harm than good and need to be replaced multiple times a year. Some even produce a static charge that could result in the combustion of the dust. Instead, look for one that is fully grounded and bonded to ensure static charges can’t become an ignition source. 

Benefits of Selecting the Right Vacuum

Here are some benefits of selecting a certified, intrinsically safe vacuum:

  • Filtration system with HEPA filters that is 99.8% effective at keeping fine dust particles from entering the air.
  • Properly grounded and bonded to eliminate the possibility of static shock.
  • Virtually eliminates the chance of explosion by trapping combustible dust.

Combustible Dust: Understanding How To Prevent Industrial Fire Hazards

Many manufacturing and mining industries create large amounts of Combustible Dust that have the potential of becoming highly explosive and causing fatalities and millions of dollars in damage.

More than 450 accidents involving combustible dust have killed nearly 130 workers and injured another 800-plus since 1980, according to a Center for Public Integrity analysis of data compiled by the federal Occupational Safety and Health Administration and the U.S. Chemical Safety Board. These fires and explosions have been caused by a variety of dust sources including sugar, nylon fiber, coal, iron, plastic and wood. Most in the manufacturing industry are aware of some of the dangers and have read or seen reports of these explosions in the news.

An explosion ripped through the New Cumberland A.L. Solutions titanium plant in West Virginia on December 9, 2010, fatally injuring three workers. The plant workers were processing titanium powder at the time of the explosion. The AL Solutions incident is one of nine serious combustible dust incidents investigated by the CSB since 2003, including the Imperial Sugar disaster near Savannah, Georgia, in 2008 as well as three combustible dust incidents over a six month period in 2011 at the Hoeganaes facility located in Gallatin, TN. These nine explosions and fires caused a total of 36 deaths and 128 injuries.

Dust and other debris will always be present in the manufacturing process. Since dust is inevitable in the process, manufacturing facilities must take the proper measures to understand the risks, learn as much as possible about the threat and take solid measures to prevent potential hazards and be prepared should an incident take place.

What is Combustible Dust?

The technical definitions for combustible dust will differ depending on the source that you reference. The Occupational Safety and Health Administration (OSHA) in the United States defines combustible dust as “a solid material composed of distinct particles or pieces, regardless of size, shape, or chemical composition, which presents a fire or deflagration hazard when suspended in air or some other oxidizing medium over a range of concentrations”. In Canada, one example is Alberta’s Occupational Health and Safety Code which defines combustible dust as “a dust that can create an explosive atmosphere when it is suspended in the air in ignitable concentrations”.

What are examples of materials that can be a combustible dust hazard?

Believe it or not the Occupational Safety and Health Administration (OSHA) lists over 120 materials as combustible dust makers. See the chart below for a full list:

What Industries Are at Risk for Combustible Dust?

OSHA notes some of the industries at risk include:

  • Agriculture
  • Food
  • Pharmaceutical
  • Pesticide
  • Rubber
  • Plastic
  • Woodworking
  • Textiles
  • Chemical
  • Recycling
  • Coal fired Power Plants

Causes of a Combustible Dust Explosion

There are three elements needed for a dust fire to
occur and is referred to as the “Fire Triangle”. They are:

  • Combustible dust (i.e. the fuel)
  • Oxygen
  • Heat source


There are also two additional elements needed to cause a combustible dust explosion, often called the “Dust Explosion Pentagon”

  • Dispersion of dust particle in sufficient quantity
  • Confinement of the dust cloud


Secondary Explosions

After the initial combustible dust explosion, there is often a secondary explosion caused. The second explosion is caused by dust that is shaken loose from the primary explosion which also ignites. The secondary explosion may be actually larger and more severe than the initial explosion.

Conditions Needed for a Dust Explosion to Occur

The simple recipe for a dust explosion to happen is for combustible dust particles to be suspended in air and include an ignition source. In reality, several other conditions generally need to be present

  • The combustible dust must release enough heat to sustain the fire.
  • The dust must be suspended in air.
  • The dust must have a particle size large enough to spread the flame.
  • The concentration of the dust suspension must be within the explosive range.
  • An ignition source must be in contact with the suspended dust.
  • Adequate oxygen must be present to support and sustain combustion

Dust Hazard Assessment for Your Facility

Plants should carefully look at the following areas to determine the potential for dust explosions:

  • Materials
  • Processes
  • Open Areas of dust
  • Hidden Areas of dust
  • Dust dispersion sources
  • Ignition sources

Preventative Measures

  • Develop a housekeeping plan
  • Use only approved vacuum cleaners for dust collection
  • Find and eliminate hidden areas where dust accumulates
  • If possible, avoid or minimize horizontal surface where dust may accumulate
  • Use cleaning methods that do not generate dust clouds
  • Use proper electrical and ventilation systems


  • Develop and implement a combustible dust inspection and control program including when inspections will take place and specific actions to control dust.
  • Develop a hot work permit system for activities such as welding and cutting.
  • Develop an ignition control program to eliminate or reduce sources of ignition. Keep ignition sources away from dusty areas or use suitable controls.
  • Educate and train employees regarding the hazards of combustible dusts and their role in eliminating the threat of explosions
  • Inspect for dust at regular intervals.
  • Regularly inspect machines, ducts, and ventilation systems for dust.

Intrinsic Safety

HafcoVac explosion-proof industrial vacuums are suitable for use in Class I, Class II, and Class III environments, Division 1 and 2. Our explosion-proof pneumatic vacuums:

  • contains no moving parts, eliminating the possibility of ignition from mechanical friction or contact.
  • uses no electricity, eliminating sparks from motor arcing, shorts, switches, etc.
  • are fully grounded when an explosion-proof vacuum unit configuration is ordered, ensuring dangerous static electricity will not accumulate.

Intrinsic Safety is a protection technique for equipment operating in explosive environments. The principle states that electrical and thermal energy must not build up sufficiently to discharge. With heat or friction risks such as those present when using an electrically operated industrial vacuum safely eliminated, static electricity remains.

The complete grounding of all components, including air supply line, vacuum generating head, collection drum, dolly and vacuum hose ensure that static electricity is continuously dissipated, protecting against dangerous static buildup, which could lead to electrostatic discharge (ESD), posing potentially serious consequences when in the presence of combustible substances. HafcoVac explosion-proof vacuum models factory equipped as an explosion-proof configuration ensures static electricity will not accumulate.

It is critically important that the operator understands the functions of the grounding system. Inspections are suggested prior to each use to ensure the integrity of all grounding wires and points. Care must be taken to not circumvent any grounding safeguards, and should also be exercised to ensure parts such as hoses aren’t used interchangeably with those from non-explosion proof systems.

Are HafcoVac’s Vacuums Certified Explosion Proof?

Stainless Vac

To this date, there are no published certification procedures for air-powered (pneumatic) equipment.

HafcoVac anti-static grounded units (“x” model designation) machines meet the criteria for intrinsically safe operation – no moving parts, non-electric & fully grounded means the unit will not spark and will not generate dangerous amounts of heat.

Additionally, we have designed these machines specifically for use in hazardous locations – building in a double safeguard of conductive static dissipative materials & connections, coupled with complete grounding of all components of the unit.
