What are the ATEX zones?
What are the ATEX zones?
ATEX Zone 1 (high risk gas/vapour) ATEX Zone 2 (medium risk gas/vapour) ATEX Zone 21 (high risk powder/dust) ATEX Zone 22 (medium risk powder/dust)
What is ATEX Zone 1 certification?
ATEX Zones Zone 1 – a place in which an explosive atmosphere consisting of a mixture with air of flammable substances in form of gas, vapor or mist is likely to occur in normal operation occasionally.
What does ATEX rating mean?
/ explosive atmospheres
If a product / piece of equipment has official ATEX certification, it has been fully tested and approved to be safe to use in hazardous / explosive atmospheres.
How many ATEX zones are there?
four ATEX
There are four ATEX classification to ensure that a specific piece of equipment or protective system is appropriate and can be safely used in a particular application: 1.
What is the difference between Dsear and ATEX?
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 is the purpose of ATEX?
ATEX is the name commonly given to the two European Directives for controlling explosive atmospheres: 1) Directive 99/92/EC (also known as ‘ATEX 137’ or the ‘ATEX Workplace Directive’) on minimum requirements for improving the health and safety protection of workers potentially at risk from explosive atmospheres.
What is the difference between ATEX and UL?
The difference between these three is the testing/classification body. Each rating is created by a recognised standards body with ATEX Being European, UL being American and IECEx often used for international standards. Your company may choose a specific standard to base decisions from.
How do you read an ATEX rating?
The ATEX code is an alphanumeric string that denotes the certification achieved by the product along with the environment and conditions it is suitable for. The code can be broken down into a prefix, for example: CE0518 Ex II 2 G and suffix, for example: Ex d IIC T6 Gb.
What is ATEX certification used for?
ATEX certification ensures that equipment will work safely in explosive environment without causing any accident if used as per the manufacturer’s recommendations. Equipment used in explosive atmosphere within the European Union (EU) and the European Economic Area (EEA) must be ATEX certified.
Is intrinsically safe?
ISA-RP12-6 defines intrinsically safe equipment as “equipment and wiring which is incapable of releasing sufficient electrical or thermal energy under normal or abnormal conditions to cause ignition of a specific hazardous atmospheric mixture in its most easily ignited concentration.”
What do you mean by ATEX Zone 2?
ATEX Zone 2. A place in which an explosive atmosphere consisting of a mixture with air of dangerous substances in the form of gas, vapor or mist is not likely to occur in normal operation but, if it does occur, will persist for a short period only.
What is the ATEX directive 94 / 9 / EC?
2) Directive 94/9/EC (also known as ‘ATEX 95’ or ‘the ATEX Equipment Directive’) on the approximation of the laws of Members States concerning equipment and protective systems intended for use in potentially explosive atmospheres. ATEX classifications are in zones, derived from the US ‘HAZLOC’ standard.
What are ATEX zones for dust explosive risk?
The ATEX zones for dust explosive risk are indicated with zone ATEX 20, 21, 22. In order to define the ATEX zones the following aspects need to be considered: Hazardous sources, all points where gas, damp or dust could possible break out need to be documented The quantities of gas, vapor and dust that can be released in the are calculated
What are the ATEX zones for gas and mist?
The ATEX zones for gas or mist explosive risk are indicated with ATEX zone 0, 1 or 2. The ATEX zones for dust explosive risk are indicated with zone ATEX 20, 21, 22. In order to define the ATEX zones the following aspects need to be considered: Hazardous sources, all points where gas, damp or dust could possible break out need to be documented
