Zone 1, and Zone 0 depending on the level of risk. With the ATEX Directive, every Zone is associated to a Category, and every electrical equipment is classified according to these categories, certifying in which areas it can be safely used. Under the reviewed ATEX Directive for Zone 0 1 areas, the standard EN 600790:2012 came into effect in ...
ATEX Zone 0. The ATEX 137 Workplace Directive (Directive 99/92/EC) defines safety standards that apply to different levels of dangerous working environments. The more dangerous the environment, the more stringent the requirements. ATEX Zone 0 is one of the two most dangerous zoning classifications.

Hazardous Gas, Vapour and Mist Environments: ATEX Zones 1 and 2. A good example of an ATEX Zone 1 or ATEX Zone 2 classified operation would be a chemical or petrochemical plant, where there is a heightened risk for explosion during the course of normal day to day operations.
• In Division 2, Zone 1 and Zone 2 industrial areas such as: chemical plants, oil and gas refineries, paint and varnish manufacturing plants, gasoline bulk loading terminals, grain elevators and processing industries, coal processing or handling areas, or finishing areas where atmosphere may contain hazardous gases and/or dust
ATEX Dangerous Zone Definition Group I – coal mine with probable presence of firedamp and/or combustible dust. Underground workings in mines and in their machinery aboveground, probably exposed to the risk of firedamp and/or combustible dust emissions.
All of them will have classified areas, as explained in the Atex Zone Classification. 1. Chemical industry. In the chemical industry, flammable gases, liquids and solids are processed and used in many processes. Explosive mixtures may form in these processes. Plants for the production and handling of sulfur. Work, handling and storage areas.
ATEX dust zones Zone 20 Zone 21 Zone 22 For example, a mill or pneumatic conveying system. Zone 21 Primary grade of release gives rise to Zone 21 a place in which an explosive atmosphere, in the form of a cloud of combustible dust in air, is likely to occur occasionally in normal operation.
Equipment category (Could be 1, 2, 3 depending upon Zone of intended use) Type of flammable atmosphere (G = Gas, D = Dust) Mining applications (M1 = equipment remains energised, M2 = .

Components and solutions with ATEX certification for all steps in the automation process. Legal directives such as NEC/CEC in the USA and Canada, and Europe''s 2014/34/EU (ATEX) are in place alongside other regulations to reduce the risk of explosions in high risk operating areas and increase industrial machine safety.
The Vortex® Aggregate Diverter™ is designed to meet the demanding applications with handling material such as sand, gravel, whole grains, and coal. The optional inlets, chute liners, and bucket liners extend the life of this valve when handling abrasive materials. The diverter''s access panel allows for quicker entry to the interior of the diverter for inspecting and cleaning the valve.
ATEX Groups Zones ... Temperatures < 150°C or < 450°C according to coal dust accumulation on equipment. Group II. Temperature class for gas (G) Permissible surface temperature of electrical equipment. T1 T2 T3 T4 T5 T6. 450°C 300°C 200°C 135°C 100°C 85°C. Ignition Temperature for Dusts
after ignition. So the liquid being pumped has nothing to do with ATEX. Typical examples of productions where combustible dust is of major concern, is the handling of cereals, animal feed, paper, wood, chemicals, plastics and coal.
Zone 21 (ATEX 1999/92/EC) definition. What is a Zone 21 hazardous area? A Zone 21 area is classified as a place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of powder or dust is likely to occur in normal operation occasionally.
