What is the difference between ATEX and DSEAR?
DSEAR is for the assessment of a dangerous substance (gas, liquid, dust etc.) and ATEX provides guidance on the type of equipment you should use in each area once you have classified them as the result of an assessment.
What are ATEX zones?
ATEX uses Zone numbers to distinguish between environments with different levels of danger. ATEX distinguishes between explosive atmospheres that arise because of gases, vapours and mists and those that arise from dusts. ATEX Zone 0 is the most hazardous workplace type where gases, vapours and mists are present.
What comes under DSEAR?
The Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) are concerned with preventing or limiting the harmful effects of fires, explosions and similar energy-releasing events and corrosion to metals. Gases under pressure and substances corrosive to metals. Celluloid.
How do you classify ATEX zones?
ATEX zones are classified according to two parameters: – the types of combustibles that may be encountered (dust or gas) – the frequency or duration during which an explosive atmosphere is likely to occur.
What is a DSEAR zone?

What does DSEAR stand for?
the Dangerous Substances and Explosive Atmospheres Regulations 2002

Does Diesel fall under DSEAR?
Diesel is generally recognised to have a flashpoint between 55 and 60 ºC and is therefore now under DSEAR. Diesel is known to become flammable when the temperature of the fuel is raised to its flashpoint or is presented to a source of ignition in the form of a mist.
What does ATEX stand for?
explosive atmospheres
What Does ATEX Stand For? ATEX comes from the description of the hazardous materials in question, as written in French — “Appareils destinés à être utilisés en ATmosphères EXplosives.” The translation into English reads, “Devices intended for use in explosive atmospheres.”
