ATEX Specification Requirements
When specifying a pressure washer for use within an ATEX or zoned hazardous area, it is important to establish the exact requirements of the zone before a machine can be specified.
Due to the wide variety of sites, processes and operations carried out within ATEX-zoned areas, the required equipment specification can vary significantly from one application to another.
Establishing the ATEX Zone Rating
The first requirement is to establish the exact Zone rating for the area in which the pressure washer will be used. We may require additional information before we can prepare a proposal, including the required T class and any other classifications that apply to the area.
The risk assessment used to determine the required Zone rating for equipment entering a zoned area should be carried out by the client or end user. It is the responsibility of the client or end user to specify exactly what equipment is permitted to enter and operate within the zoned area.
The examples shown are not intended to suggest that any particular rating is suitable for your application.
The required ATEX rating must be specified by the client or end user based on the site’s risk assessment and zoning requirements.
Every project is tailored to suit the site, operational requirements and environmental obligations.
