Additional Information

Dust Ignition Prevention

Combustible dust can be ignited by electrical equipment in several ways, for example by: - Surfaces of the equipment that are above the minimum ignition temperature of the dust concerned. - The temperature at which a type of dust ignites is a function of the properties of the dust;

Sources of Ignition

Ignition of a flammable mixture, or explosive atmosphere, may occur following an arc, spark or hot surface during the use of electrical as well as nonelectrical equipment. Arcs can result from the discharge of stored energy or from switching contacts.

Sources of Release & Grades of Release

Sources of release may originate from almost anywhere in the process or storage area of an explosive atmosphere site. Flammable materials may be released from pumps, pipes, flanges, valves, sampling points, or other similar equipment. The release may be caused for example by either process seal failure, leakage to flanged joints, ruptures to pipe work, spillage from over filling of floating roof storage tank (e.g. following faulty level switch reading), other mechanical failure, or an inadvertent operations error.

Zone Definitions

Under IEC rules explosive atmospheres are divided into three zones, or areas of risk (in the case of gas and vapour), and IEC 60079-10 recognises these as Zone 0, Zone 1 and Zone 2.

Read more

Ambient Temperature

The service temperature is the surrounding temperature of the environment in which the equipment is installed, whether indoors or outdoors. A given piece of electrical equipment will be approved for a stated maximum service temperature in which it is safe to operate. For example under the IEC 60079 series the normal service temperature range would be -20°C to +40°C, unless otherwise stated on the product certification. In some cases the maximum (or minimum) permitted service temperature will be adjusted taking into account any temperature rise under normal operation and the surface temperature rating of the equipment.

Explosion Hazards

The danger of explosion exists when flammable materials are combined with air in amounts that can create an explosive mixture. This can occur during storage, movement, process, production, accidental release and manufacture of such flammable materials. The primary requirement is for the operator to prevent conditions where a flammable mixture is released to the atmosphere.

Relationship between EPLs & Zones

Relationship between EPLs & Zones Where only the zones are identified in the area classification documentation, then the relationship between EPLs and zones from Table 1 of IEC 60079-14 shall be followed. As an alternative to the relationship given in Table 1 of IEC 60079-14 between EPLs and zones, EPLs can be determined on the basis of a risk, i.e. taking into account the consequences of an ignition.

ATEX Directive Development

When did the initial ATEX Directive take effect? The ATEX Directive 94/9/EC of March 23rd 1994, was the first ATEX Directive for products and equipment and was adopted by the European Union (EU), under its “new approach” strategy. This was primarily to facilitate free trade in the EU by aligning the technical and legal requirements in the member states, for products intended to be used in potentially explosive atmospheres.
