Ensuring Explosion Safety with ATEX Compliance Solutions
Explosion safety is a critical concern for industries dealing with combustible materials. Dust explosions, in particular, pose significant risks in manufacturing environments, but with the right systems and equipment, hazards can be mitigated. At JOA Air Solutions, we provide comprehensive solutions to prevent explosions and ensure compliance with ATEX zoning regulations.
What are Dust Explosions?
Dust explosions can occur in various industries due to the accumulation of combustible dust. These explosions not only threaten worker safety but can also lead to costly damage to facilities.
Explosion Hazard Examples
Common types of dust explosions include solids like:
- Sugar dust explosion – Read blog about Sugar Explosion
- Combustible dust – Read blog about Combustible Dust Control
- Flour explosion – Read blog about Flour Explosion
- Starch dust
- Cocoa dust
- Protein explosion
- Milk powder dust
- Plastics & Rubber dust
- Pigment dust & Toner
- Grain dust
- Textiles & Fibres
- Carbon dust
- Corn dust
- Metal Dust, like Aluminium, Chromium, Magnesium or Steel
Why Explosions May Occur
Explosions occur when a mixture of combustible dust particles and air comes into contact with an ignition source. In industries handling fine powders or dust, these materials can easily become suspended in the air, creating a potentially explosive atmosphere. Common triggers include hot surfaces, open flames, static electricity, or even mechanical friction. Without proper safety measures, such conditions can lead to devastating explosions.
Well known are the three elements of the Fire Triangle: Combustible Dust (fuel), Ignition Source (heat) and Oxygen. Additional elements needed for a combustible dust explosion are confinement of the dust cloud and dispersion of dust particles in the right, sufficient quantity and concentration.
Explosion Hazard Reduction with Reduced ATEX Zoning
Reducing ATEX zoning is one of the most effective ways to mitigate explosion risks. ATEX zoning involves classifying areas where explosive atmospheres may occur and designing equipment and systems that minimize the potential for ignition in these zones.
JOA Air Solutions offers tailored solutions to help companies manage their ATEX zoning effectively, ensuring that explosion hazards are minimized. During the Pre-Engineering phase, JOA will always follow the following priority:
Source elimination
Source extraction
Ventilation
By optimizing extraction systems, our solutions help reduce the extent of ATEX zones, which in turn lowers the investment required for ATEX-certified equipment and costs of expensive insurances.
Next to having the right industrial extraction system and ventilation system in place, regular housekeeping is also important and can by done with Central Vacuum Cleaning Systems or Mobile Vacuum Cleaning equipment.
The right combination of combustible dust management, may lead to explosion risk mitigation and more protection for your operators and assets.

Explosion Safety
Protection against explosions in industrial environments involves a combination of preventive and protective measures. Key methods include:
- Dust collection systems to capture and remove combustible dust before it can accumulate.
- Cyclone separators and scrubbers to efficiently separate hazardous particles from the air.
- Explosion prevention systems designed to mitigate explosion risks by controlling ignition sources and limiting the presence of explosive atmospheres.
- ATEX zoning to classify hazardous areas and ensure compliance with regulations.
To prevent explosions, industrial manufacturers must implement a series of safety measures:
- Dust control through effective dust collection and filtration systems.
- Regular cleaning to avoid dust accumulation on surfaces.
- Proper ATEX zoning to limit areas where explosive atmospheres may form.
- Monitoring and control systems that detect hazardous conditions early.
- Staff training on explosion prevention and the safe operation of equipment.
Reducing the risk of an explosion involves minimizing the presence of combustible dust and ensuring that the atmosphere is free from ignition sources. Using well thought through, custom-made extraction systems helps limit dust accumulation and reduce ATEX zones, lowering the risk of explosion. Using Flow Rate Measurement also reduces the risk of explosion.
An explosion prevention system is a set of integrated safety measures designed to prevent the formation of explosive atmospheres and the ignition of combustible materials. These systems include:
- Dust collection systems that eliminate dust from the air.
- ATEX-certified equipment that operates safely in hazardous zones.
- Control measures to monitor air quality and manage particle concentrations.
Every manufacturer which is working with or produces a explosible substance (dust, vapor or gasses) will need to comply to the ATEX / Explosion Zoning directives, like the 1999/92/EG, also known as the ‘social directive’ or the 2014/34/EU directive, which is also known as the ‘equipment’ or ‘process directive’.
This directive describes the minimum requirements for equipment used in ATEX zones or in which explosive material is handled. This directive is therefore more driven by conformity. Globally, the IECEX certification is widely accepted as well. Â
Effectively eliminating ultrafine particles (UFPs), with < 0.1 mg/m3 is possible through a deep understanding of particles and proper design. Â
A dust explosion occurs when a mixture of combustible dust and air encounters an ignition source, such as static electricity or a hot surface. The dust particles must be fine enough to become suspended in the air, creating a highly combustible atmosphere. For a deeper understanding of dust explosions, visit our blog
Dust explosions can cause severe damage to industrial facilities, including structural damage, equipment loss, and significant production downtime. They also pose serious safety risks to workers, including injuries or fatalities.
An ATEX zone is a classification used to identify areas where explosive atmospheres may form due to the presence of combustible dust or gases. ATEX zones help manufacturers understand the risk level of different areas and ensure that the right safety measures are in place. More about ATEX zones can be found in our ATEX blog.
ATEX explosion zones are categorized based on the likelihood of explosive atmospheres occurring. They include:
- Zone 0: Areas where explosive atmospheres are present continuously or for long periods.
- Zone 1: Areas where explosive atmospheres are likely to occur occasionally.
- Zone 2: Areas where explosive atmospheres are unlikely to occur but may happen for short periods.
