Dust explosion protection in Europe
  • We can conduct dust testing and determine eight dust explosion parameters to analyse the risks of an explosive dust environment in your production facility. We cooperate with leading Russian and foreign laboratories, so we can arrange tests not only of common substances, but also of rarely encountered ones.
  • The customer will be provided with basic data for analysing the risks of accidents in production. On the basis of this, he will be able to plan prevention and explosion protection measures.

Combustible dust is a hazard in metallurgy, woodworking, food processing and pharmaceutical production. Combined with air, it forms an explosive aerosol suspension which, on contact with an ignition source, leads to an explosion. First localised and then secondary, with widespread destruction.

Dust, air and ignition sources are present in every production facility. Therefore there is always a risk of explosion. Dust testing helps to accurately assess the risk because its explosion and fire hazard properties depend on the presence of specific substances in it.

Operating companies are not always able to carry out the studies themselves. A 'controlled explosion' is needed to determine several dust parameters, which can only be safely arranged at a test site.

Explosion protection in production facilities has its own requirements:

  • ATEX 114 (2014/34/EU) — establishes the employer's obligation to protect people against explosion;
  • IEC 60079-10-2:2015 - gives definitions of combustible dust and explosive dust environments and sets out the classification of explosive zones;
  • EN 1127-1-2014 - describes ignition sources;
  • ATEX 114 (2014/34/EU) - contains requirements for equipment for use in potentially explosive environments.

National legislation also establishes its own specificities in technical regulation.

Regulations require that the owner of a hazardous facility must carry out a risk analysis of the workplace and take measures for explosion prevention and explosion protection. Dust testing is the first step to fulfil this obligation.

Dust testing will allow planning of explosion prevention and explosion protection measures, resulting in:

  • significant reduction of accident risk for the owner of the hazardous facility and protection of personnel and equipment against explosion;
  • the owner prevents losses from destruction of capital facilities, payments to victims;
  • the owner complies with industrial safety rules and avoids administrative sanctions.

Dust testing traditionally includes:

  • laboratory analysis of dust to determine dispersity, humidity, smouldering and ignition temperatures, and other parameters;
  • a series of experimental explosions in an explosion chamber.

Each laboratory is accredited for its own test area, so it is not always possible to carry out all tests in one place. We cooperate with leading institutes in the field of explosion protection from various countries and can arrange dust analysis even for rare substances. We can accurately determine the parameters of airborne dusts in your plant and their flame propagation limits.

ATEX.CENTER is an official partner of RSBP spol. s r.o., a Czech company with 30 years' experience in explosion protection. RSBP has its own research and development facility, where we organise "controlled explosions".


  • Determine characteristics and parameters

  • Сonduct a series of experimental explosions

  • Provide a report on the substance being handled

  • Give recommendations on reducing risks and costs

Work stages

Step 1 Dust sample collection
Step 2 Delivery of dust samples to the laboratory
Step 3 Determination of dust explosion characteristics
Step 4 Conduction of experimental dust explosions to confirm dust explosion characteristics and parameters.
Step 5 Submission of a dust explosion report with risk reduction recommendations


  • We will take dust samples for analysis and deliver them to the laboratory ourselves. You will receive a report with the dust explosion hazard parameters:
    - minimum explosion concentration / LEL
    - maximum explosion pressure / Pmax
    - maximum explosion pressure growth rate / (dp/dt)max
    - explosion class / Kst
    - minimum explosion temperature / MIT
    - minimum explosion temperature / GT
    - minimum explosion energy / MIE
    - oxygen concentration limit / LOC
  • This set of characteristics is sufficient for a full assessment of the risk of an accident in production and for the selection of explosion protection equipment.
