ATEX Case Studies / ATEX Training

GRUPA WOLFF carries out complex works in the field of explosive safety in industry. Basically, our activities include: conducting an Explosive Safety Audit, carrying out an Explosion Risk Assessment and preparing Explosion Protection Documents for both existing and newly established process systems.

An integral part of both the Explosion Risk Assessment document and the Explosion Protection Document is determination of the scope and type of explosion risk zones. Moreover, our engineers organise training course on explosive safety and ATEX Directives.

ATEX Audit

The ATEX Audit is the cheapest and quickest method of assessing the critical points in an the plant that should be addressed first. The audit report will therefore allow you to focus on the tasks that will most powerfully and often most quickly reduce the risk of explosion and fire in your facility. Such an approach not only makes it possible to prioritise actions, but also to schedule them over time, which is important, especially in the case of costly modifications.

ATEX Tailored Training

Closed-type training sessions are organized specifically for a given company or organization. The flexibility of such a solution allows for better adaptation of the thematic scope, date, and place of training to the client's requirements. Typically, between 5 and 15 people participate in the training. During ATEX training, you will learn about, among other things: the causes of exemplary explosions that occurred in the industry; employer's obligations regarding explosion safety; principles of classification, determining the range, and marking of explosion hazard zones; changes resulting from the new ATEX directive; principles of operation and selection (limitations) of explosion protection measures; principles of carrying out repairs and servicing of devices in explosion-proof design; videos with practical tips.

Dust explosivity testing

Testing dust explosivity is intended to answer the question of whether a particular dust type is explosive and, if so, how hazardous it is. For example, it may be that the particular dust is explosive, but its minimum ignition energy is so high that the risk of explosion is virtually non-existent. It may also be the case that the dust is not explosive and thus a full range of tests would generate unnecessary cost. For these reasons, it is extremely important to divide the tests into two stages and to select only those parameters that need to be established. This reduces the cost of testing.

Explosion Protection Document

We prepare Explosion Protection Documents (known as EPD) for: Existing facilities and process installations that do not have the respective document Installations and facilities where changes affecting the level of explosion safety have been made (e.g., changes in technology, raw materials, use of new devices, etc.) Importantly, the Explosion Protection Documents prepared by the WOLFF GROUP always include an explosion risk assessment and classification of explosion hazard zones.

Explosion Risk Assessment

Our team of Engineers conducts professional risk assessments of installations at the design stage and for existing process installations, the final stage of which is the preparation of an Explosion Risk Assessment document. It identifies hazards present in the workplace related to the occurrence of flammable and explosive dusts, powders, liquids, vapors, and gases. Additionally, it specifies the steps that need to be taken to eliminate and/or reduce these threats.

Explosion Risk Zones

Engineers of GRUPA WOLFF perform works consisting in determining proper explosion risk zones with their scope for both existing and newly constructed plants and facilities. In the case of newly constructed facilities / plants, the engineers asses the plant safety in the design phase, which allows to determine at the right moment technical specifications for electric or non-electric equipment that may be installed in explosion risk zones. This solution allows to select properly the equipment category prior to the purchase process.

Model approach to explosive safety in an industrial plant

Model approach to explosive safety in an industrial plant

Step 1
ATEX Audit

During the ATEX Audit, we will focus on deficiencies in explosive safety and indicate tasks that should be performed first to have the strongest impact on safety improvement.

Step 2
Protection Concept

The result of the ATEX Audit is also a preliminary concept of protecting the installation from explosion. It allows estimating the costs of protections. After testing the explosiveness parameters of the dust from the installation, we move on to the final concept and design.

Step 3
Design and selection of protections

After accepting the concept and testing the explosiveness parameters of the dust from the installation, we proceed to the final selection of explosion protections and create a design that takes into account all required changes in production.

Step 4
“Turnkey” delivery and installation

We coordinate the entire delivery and installation process of protections. We have our own service teams with experience in performing installation without the need to stop the investor’s plant operation.

Step 5
Execution of ERA and EPD

We conduct a post-implementation Explosion Risk Assessment (ERA) and prepare (or update) the Explosion Protection Document (EPD). We usually also conduct training for the crew in the field of explosive safety.
