Hazardous area classification

It is part of the DSEAR requirements to identify hazardous areas in processing plants, and to identify them clearly. Euratex 3D Zonal Mapping is a tool to achieve this requirement, and creating these maps in 3D makes hazardous area classification clear and easy.

An Interactive 3D Map

It is of vital importance that potentially hazardous areas (dust and gas explosions) within a production area are well defined, so that all personnel operating in and around those locations are aware of any potential dangers around them. Zonal mapping is a way to highlight these areas in a way that all personnel can understand and recognise. Hazardous area classification zonal maps are usually 2 dimensional, but at Euratex we aim to bring safety to the next level with Euratex 3D Zonal Mapping. This is a valuable tool to allow engineers and contractors to analyse hazardous area zones before entry, via an interactive 3D map.

These maps often feature a customisable animated walk-through that can be easily created to allow engineers and personnel to see each zone. This new tool grants access for design engineers to see where zones exist before process plant modifications are even produced. These maps are easily adaptable to any changes or modifications to the process.

Figure 1 is a screenshot of a sample 3D map of a main building assembly. On 3D software, it can be rotated and enlarged, with the potential added feature of an interactive walk-through tour of the map. You can create a pathway for the spectator to walk through the map, turning left and right to see the surrounding equipment and area, as if you were a site worker navigating around the area.

One of the great things about our maps is that you don’t need fancy or expensive software. They can be viewed on almost any device including tablets and smart phones, by simply downloading an application.

Figure 2 shows hazardous area zones within a production facility. The vessels are colour coded to represent the internal zone classification. External zone “bubbles” represent an potentially hazardous area outside of the vessel when a hatch is open for instance. A scaled “worker” is placed to help identify the size of the structure and the size of the hazardous areas.

Personnel can easily see from this that certain areas require special care and attention when entering or working, which saves time and reduces the likelihood of injury.
