ATEX is short for the French phrase “Atmosphères Explosibles”, and refers to two EU Directives which set out legal requirements relating to potentially explosive atmospheres:
It is primarily the Workplace Directive which would be relevant to the operations of a pharmaceutical facility. It is likely that the facility handles materials such as flammable solvents (e.g. ethanol, IPA, hexane) and fine organic powders (e.g. cellulose), which due to their inherent material properties, have the potential to form an explosive atmosphere on site. If not managed correctly, there is a risk that handling of these materials could lead to an explosion, which could cause severe consequences for those present on site, the plant and equipment, and even for those off-site.
In Ireland, the ATEX Workplace Directive is implemented by Part 8 (Explosive Atmospheres at Places of Work) of the Safety, Health and Welfare at Work (General Application) Regulations 2007. Under these regulations, those in control of a workplace where an explosive atmosphere could form have a number of legal responsibilities. These include:
The requirement to classify places where explosive atmospheres may occur is also known as “Hazardous Area Classification”. Hazardous areas can be classified into zones based upon the expected frequency of the occurrence and duration of an explosive atmosphere, as follows:
All hazardous areas (also known as ATEX Zones) must be clearly indicated by signage, and all equipment within these areas must be suitably Ex-rated for use in that zone.
