Explosion Hazard Zones
Scope of works
- classification of type and determination of the range of explosion hazard zones depending on the presence of combustible dusts, gases, vapours or hybrid mixtures;
- classification of type and determination of the range of explosion hazard zones on the design stage in order to eliminate any incorrect assumptions and select the equipment and machinery with appropriate explosion protection measures;
- verification of the determined explosion hazard zones, due to the modifications introduced to the process installation in question, with significant impact on explosion safety;
- analysis of the current condition as well as development of a concept for changing the types of the determined explosion hazard zones and limiting their range (increases safety; reduction of equipment purchase costs).
Description of our activities
Our team of engineers provides comprehensive services for the adjustment of industrial facilities to the requirements of the ATEX directive (implemented in Poland by the Regulation of the Minister of Economy of 8 July 2010 on minimum requirements for the occupational safety and hygiene, related to the possible occurrence of explosive atmosphere in the workplace).
One of our main tasks in this regard is the classification and determination of the range of explosive hazard zones. It is one of the key and most important tasks to be undertaken in order to provide the appropriate and legally required explosion safety level in industrial facilities. This report may be provided as an independent document or as part of the Explosion Risk Assessment or Explosion Protection Document. This allows us to deliver our work in stages comfortable for the client (e.g. depending on the progress of works at the facility).
The aforementioned services can be provided for currently operational and newly built process installations. In the case of a new installation, the designs and documentation are taken under careful scrutiny. Acting on such an early stage of implementation of a new production installation or industrial facility investment enables the elimination of many mistakes and incorrect assumptions. One of the advantages is the possibility of appropriate selection of equipment and accessories for operation in the applicable explosion hazard zone (correct ATEX certificate).
Under the Regulation of the Minister of Economy of 8 July 2010 on minimum requirements for improving the occupational safety and hygiene, related to the possible presence of explosive atmosphere in the workplace […], the employer divides explosion hazard areas into zones, based on the probability and duration time of explosive atmosphere occurrence in the following manner: zone 0, zone 1, zone 2, zone 20, zone 21, zone 22.
The same document indicates the requirement for the employer to develop the Explosion Risk Assessment and Explosion Protection Document.
