Description Explosion safety: ATEX analysis
Since 2003, ATEX legislation has been mandatory within the EU and EFTA. All machines placed in hazardous areas and built after 2003 must comply with the ATEX 114 directive. This requires manufacturers to affix an Ex marking, declaring that the machine is suitable for zone 1, 2, 21 or 22.
Machine owners themselves are responsible for complying with the ATEX 153 directive. This requires the preparation of an Explosion Protection Document (EDS), which demonstrably defines hazards, zones and measures. ATEX analysis for explosions is often applied to installations such as belt conveyors, elevators and loading bellows.
ATEX analysis for explosion safety
Jansen&Heuning carries out explosion safety analyses based on the NEN-EN-1127-1 standard. Here, potential ignition sources are systematically inventoried and assessed. This process is known as an ignition analysis.
The analysis proceeds in three steps:
- Identification of ignition sources
- Selection and technical assessment of relevant ignition sources
- Assessment of the machine against the installation’s ATEX zone directive
If necessary, we recommend additional measures to make the machine safe to use within the defined danger zone.
An ATEX analysis is required when
- a new machine is built into an installation
- a machine/plant was commissioned earlier than 2003 and an ignition analysis has not yet been carried out for it;
- or a machine/plant is modified in such a way that a new or additional risk analysis is important.
Jansen&Heuning uses ISO 80079-36/37 as the basis for the ignition analysis.
Explosion protection document (EVD) required
Prior to the ignition analysis, a valid Explosion Safety Document (EVD) is required. This document describes:
- The workplaces and processes
- The substances present and their properties
- The hazard sources per zone
- Hazard zone drawings
- Risk assessments
- The safety measures taken
An ESD is required by law for any installation where explosive substances or gases are present.
