Explosion safety (ATEX 153)

Depending on the material, a dust cloud can lead to explosions. The risk of a dust explosion is sometimes greater than you think. Sometimes a spark is enough. After the first dust explosion, there can be a domino effect of several explosions. This happens when dust is scattered throughout the factory and is thrown into a dust cloud by the first explosion. This can have major consequences for the factory and your employees. By preparing an explosion protection document (EPD) and implementing appropriate measures, you can minimise the risk of dust explosions. An explosion protection document is required by law and regulations. In addition, many insurance companies require an EPD.


Laws and regulations

Every organization that works with solid substances is obliged to carry out an in-depth investigation (also known as an in-depth RI&E) into dust explosions. This in-depth study is based on the European directive ATEX 153, which has been adopted in the Arbowet (Dutch Working Conditions Act). The Working Conditions Actstipulates that the hazard zone classification, risk assessment and explosion safety measures must be recorded in an explosion safety document.


What does an explosion protection document mean for your company?
In the in-depth RI&E Explosion Safety, an inventory is made of which dust explosion hazards are present within your organisation. During the inventory, the following will be investigated:

  • the physical properties (explosion parameters) of the substances;
  • the hazard zone classification (explosion danger of rooms/installations);
  • the ignition sources;
  • the controle measures;
  • the risk analysis.


The results of the investigation are compiled in an explosion protection document. Based on the identified hazards, an Action Plan is drawn up in which a management proposal is made for each risk. An EPD by Schouten Advies contains at least:

  • a description of the workplace and workstations;
  • a description of the processes and activities;
  • a description of the materials used and safety-technical parameters;
  • a description of the substance properties (explosive parameters);
  • the hazard zone classification of the company (zone 20, zone 21, zone 22);
  • the identification of ignition sources;
  • technical control measures;
  • organisational control measures;
  • a risk analysis and action plan.


Given the impact that a dust explosion can have on a company, the preparation of an explosion protection document is essential. Would you like more information about the Explosion Safety Document or the method of Schouten Advies? Please contact us.
