Before any project begins a design needs to be undertaken. This is the same with your hazardous areas project. In our experience the design is where the project falls over, with insufficient detail for the installers. It's all well and good to say it’s a Zone 1, but what about other factors such as the intrinsically safe calculations and, can the equipment be relocated outside the zone?
There are several protection techniques which can be utilised, all of which have their own Australian Standard.
When it comes to dust, horizontal surfaces can contribute to the problem, although dust sitting on the surface in its own right doesn't create a hazardous area. However, when dust is agitated and can form a dust cloud it becomes an issue. So, keep in mind how the equipment or installation can be cleaned or if dusts can be directed away from electrical equipment by means of a cover.
Whether you are working on a new or existing project our team will work with you to ensure that all hazardous area electrical risks are identified and managed to meet the required standards.
