Question 1

What is explosion protection in industrial facilities?

Accepted Answer

Explosion protection covers the measures and devices designed to limit the consequences of an explosion once it has started, preventing harm to people, equipment and facilities. It includes systems such as explosion vent panels, flameless venting, chemical suppression and isolation valves, which contain the pressure and stop flame propagation within the process.

Question 2

How is explosion prevention different from explosion protection?

Accepted Answer

Explosion prevention acts before an event occurs by eliminating or controlling ignition sources and the conditions that create an explosive atmosphere (spark detection and extinguishing, bucket elevator monitoring, grounding). Protection, on the other hand, mitigates the effects once an explosion has started. A safe strategy combines both disciplines in an integrated way.

Question 3

What are ATEX solutions and when are they required?

Accepted Answer

ATEX solutions are products, equipment and services certified under the European ATEX directives (2014/34/EU and 1999/92/EC), which apply to any facility where explosive atmospheres can form from gases, vapors or combustible dusts. They are mandatory in industries such as chemicals, food, pharmaceuticals and wood products, where compliance is a legal and safety requirement.

Question 4

What does an industrial explosion safety system include?

Accepted Answer

Industrial explosion safety systems integrate prevention, protection and isolation into a single coordinated package: spark detectors, active and passive isolation valves, explosion vent panels, suppression systems and continuous monitoring. The goal is to create a complete barrier that stops the hazard at any point in the process.

Question 5

How is safety ensured in ATEX environments?

Accepted Answer

Safety in ATEX environments is ensured by combining a rigorous risk assessment, hazardous area classification, the installation of certified equipment and personnel training. This is complemented by preventive maintenance and after-sales service to keep protection and prevention systems reliable over time.

Question 6

What is explosion isolation and why does it matter?

Accepted Answer

Explosion isolation prevents an explosion that starts in one piece of equipment from spreading through ducts and pipes to other parts of the facility. Explosion isolation flap valves (NOVEx, NOVEx II), active isolation valves (ExPINCH) and chemical barriers contain the event and prevent secondary explosions, which are often the most destructive.

Question 7

Which industrial equipment are these solutions used on?

Accepted Answer

Prevention and protection solutions are used on equipment that handles or stores combustible powders: dust collectors, bucket elevators, silos, hammer mills, cyclones and pneumatic conveying systems. Each piece of equipment requires a specific design based on its geometry, the type of dust and the explosibility parameters of the process.

Question 8

Which industries need explosion protection?

Accepted Answer

Any industry that generates combustible dust or handles flammable gases and vapors. The most common are food, chemicals, pharmaceuticals, recycling, wood products, grain and metalworking. In all of them, the presence of explosive atmospheres requires ATEX solutions tailored to each production process.

Question 9

Which standards govern explosion protection?

Accepted Answer

In Europe, the main framework is the ATEX directives, supplemented by technical standards such as EN 14460, EN 14491 and EN 16447, and by the widely recognized international NFPA standards (NFPA 68, NFPA 69). Compliance with these standards is the basis for designing certified, legally valid industrial safety systems.

Question 10

Is a risk assessment needed before installing a system?

Accepted Answer

Yes. An explosion risk assessment is the starting point of any project: it identifies ignition sources, classifies hazardous areas and determines which combination of explosion prevention, protection and isolation the facility needs. Without this prior assessment, it is not possible to design an effective solution or comply with ATEX regulations.
