Much early equipment having Ex s protection was designed with encapsulation and this has now been incorporated into IEC [Ex m]. The technical dossier must be kept for a period of 10 years. The main purpose is to facilitate the proper selection and installation of apparatus to be used safely in that environment, taking into account the properties of the flammable materials that will be present. The temperature classification on the electrical equipment label will be one of the following in degree Celsius :. The most recent general source of advice was drafted by a European standards working group, but was published in the UK as BS PD R and not as a full standard. Equipment built to such a harmonised standard may assume automatic conformity with those essential safety requirements of relevant directives that are covered by the standard. The two parts of the older BS 1 Code of Practice for the control of undesirable static electricity remain current, because they contain some useful information not duplicated by the PD.

    Hazardous Area Classification and Control of Ignition Sources

    In electrical engineering, hazardous locations are defined as places where fire or explosion Technical standards were developed to identify the features of electrical. Class I, Division 2 or Zone 2 classified locations: An area where ignitable .

    Mark for ATEX certified electrical equipment for explosive atmospheres. the ATEX 95 equipment directive 94/9/EC, Equipment and protective systems Areas classified into zones (0, 1, 2 for gas-vapor-mist and 20, 21, 22 for dust) This usually involves testing and certification by a 'third-party'.
    IEC Ex is a voluntary system which provides an internationally accepted means of proving compliance with IEC standards.

    The main purpose is to facilitate the proper selection and installation of apparatus to be used safely in that environment, taking into account the properties of the flammable materials that will be present.

    The most recent general source of advice was drafted by a European standards working group, but was published in the UK as BS PD R and not as a full standard.

    The consequences of the failure of a pipe carrying process materials within the furnace should be considered in any HAZOP study.

    Class 1 / Division 2 and ATEX Zone 2 Explained

    As world trade becomes more important in distribution of electrical products, international standards are slowly converging so that a wider range of acceptable techniques can be approved by national regulatory agencies.

    It was important in the development of ideas, but provides no new methodology for users. The ATEX directive is covering explosions from gases but also solid dust which, contrary to common perception, can lead to hazardous explosions [3].

    Area classification may be carried out by direct analogy with typical installations described in established codes, or by more quantitative methods that require a more detailed knowledge of the plant.

    Equipment built to such a harmonised standard may assume automatic conformity with those essential safety requirements of relevant directives that are covered by the standard. The flash point determines if an area needs to be classified. Explosions can cause significant damage along with severe injury or worse loss of life. The introduction of electrical apparatus for signaling or lighting in coal mines was accompanied by electrically-initiated explosions of flammable gas and dust.

    Every substance has a differing combination of properties but it is found that they can be ranked into similar ranges, simplifying the selection of equipment for hazardous areas.

    There is in practice little overlap between the codes.

    Zone 0: Explosive atmosphere for more than h/yr; Zone 1: Explosive atmosphere for more than 10, but less than h/yr; Zone 2: (as in zones shown in the table above);; Temperature class or ignition temperature of Standard EN sets out the requirements for diesel powdered ATEX category 2 or 3 lift trucks. Standard intended to be applied where there may be an ignition hazard due to the presence of 2 ATEX directives (1 for products, 1 for workers).

    ➢ N ti ll l Installations at Petroleum facilities classified as Class I, zone 0, zone1, zone2». Within Europe ATEX certification of products for use in potentially hazardous atmospheres is compulsory. Zone 20 (dusts), Class II Division 1 (dusts).

    Zone 1​.
    Division 1 Flammable substances are continually present or are likely to exist under normal operating conditions. If several different flammable materials may be present within a particular area, the material that gives the highest classification dictates the overall area classification.

    Heat producing elements such as motor winding, electrical heaters, including heat tracing and lighting fixtures are often designed to limit their maximum temperature below the autoignition temperature of the material involved.

    Retrieved A dust explosion could then be an initiator of a major accident.

    The Dangerous Substances and Explosive Atmospheres Regulations DSEAR provide for the first time a specific legal requirement to carry out a hazardous area study, and document the conclusions, in the form of zones.

    Effective ignition source is a term defined in the European ATEX directive as an event which, in combination with sufficient oxygen and fuel in gas, mist, vapour or dust form, can cause an explosion.

    Zone 0 and 20 require Category 1 marked equipment, zone 1 and 21 require Category 2 marked equipment and zone 2 and 22 require Category 3 marked equipment.

    Protecting the public, workforce and environment from explosive atmospheres is paramount but not a universal standard. Every substance has a differing combination of properties but it is found that they can be ranked into similar ranges, simplifying the selection of equipment for hazardous areas. Flammable substances are continually present or are likely to exist under normal operating conditions.

    Industrial electrical equipment for hazardous area has to conform to appropriate parts of standard IEC for gas hazards, and IEC for dust hazards, and in some cases, be certified as meeting that standard.

    1. No specification is available for vehicles with spark ignition engines, and it is unlikely that such an engine could be built economically.
