Petrol stations, warehouses, some production chains - risks exist wherever explosive substances are handled. In this blog post, we will discuss the most important issues related to explosion-hazardous areas and present you with the highest level of safety equipment designed to work in explosive environments.
An ex zone refers to a potentially explosive atmosphere. The risk is particularly present where explosive substances such as dusts, liquids or gases are produced, processed, transported or stored.
The Ex mark is part of the safety marking. It indicates that an explosive atmosphere, i.e. a risk of a potential explosion, may occur in or near a building. It should be displayed in a prominent position.
Ex zone
This space requires appropriate measures. The employer is obliged, among other things, to:
designate Ex areas
avoid sources of ignition in these areas
prevent the consequences of a possible explosion
A potentially explosive atmosphere is an area where it is possible that an explosive mixture (of at least 0.01 m3 volume in a confined space) can occur whose explosion would cause a pressure increase of at least 5 kPa.
An explosion will not occur if the flammable substance in a mixture with air takes values below the lower explosive limit and above the upper explosive limit.
EX Zone
The division model is mainly used in the United States and Canada, while the rest of the world generally uses a zone system. Division 2 corresponds to zone 2, while Division 1 is either zone 0 or 1.
The division of explosion danger zones is made on the basis of the probability and duration of occurrence of an explosive atmosphere.
The JUMO PROCESStemp resistance sensor has ATEX and IECEx approvals for hazardous areas. It is ideal for use in hazardous environments due to its robust housing made of stainless steel, titanium, tantalum, Inconel® or HASTELLOY®, an operating temperature of up to 600°C and an IP65 protection rating.
My name is Saskia van der Laan, I have been working for JUMO for over 33 years. Since 2012 I have been working with great enthusiasm in the marketing department. It is my passion to use written text to translate technology into practice with the aim of informing and inspiring the reader.
