PROTECTION CONCEPTS FOR ELECTRICAL APPARATUS

‘CE’ marking has been introduced as part of the European Union’s new approach to technical harmonisation
as a means of identifying products that comply with all relevant EC Directives.
Subject to certain safeguards, products bearing the ‘CE’ mark are permitted to be sold throughout the EU
without interference from national regulatory authorities. The Directives have been put in place in order to
remove artificial trade barriers within the European Union previously caused by individual countries’ national
standards, a secondary function is as a means of regulating safety.
The Explosive Atmospheres 94/9/EC ATEX (Equipment) Directive became
mandatory on 1 July 2003.
On this date the existing Explosive Atmospheres and Gassy Mines Directives were
repealed. Since then only equipment and systems ‘CE’ marked as compliant with the ATEX
Equipment Directive (and all other relevant mandatory directives) may placed on the market within the EU.
The Directive applies to all equipment and systems for use in potentially explosive atmospheres within the EU.
The scope of the Directive includes electrical and mechanical equipment for use in Group I (mining) or Group II
(industrial) applications, both on and offshore and considers risks of ignition of potentially explosive gas, vapour,
mist and dust atmospheres. In addition, devices intended for use outside potentially explosive atmospheres that
contribute to the safe functioning of equipment and systems with regard to explosion risk are also included.

A common route to product design compliance is to apply to a Notified Body (Ex. Test House) for an EC
Type Examination Certificate. To comply, the equipment or system must meet the Essential Health and Safety
Requirements (EHSRs) listed in the Directive. Harmonised EU standards have been adopted by CENELEC and
CEN, relating to the design, construction and testing of equipment; a product complying with these standards
is deemed to meet the EHSRs to which the standards relate. Where apparatus follows a protection concept
not covered by these standards, compliance to the 94/9/EC Directive is still possible by compiling a ‘Technical
File’ from first principles, demonstrating compliance through test and assessment to the EHSRs relating to
design and construction of equipment for use in explosive atmospheres.

In addition to the 94/9/EC ATEX (Equipment) Directive, products for use in potentially explosive atmospheres
may require to be compliant with other Directives including the 89/336/EEC Electro-Magnetic Compatibility
(EMC) Directive, which became mandatory on 1/1/96. This Directive applies to virtually all electrical and
electronic apparatus potentially able to generate interfering emissions or exhibit an undue sensitivity to
interference sources.

The production quality stage of the conformity assessment procedures ensure continued product compliance
in manufacturing. Typically a manufacturer should have a certified ISO 9000 quality management system and
comply with one of the quality modules in the ATEX Equipment Directive, however this will vary depending on
product equipment category; equipment used in higher risk areas will require more onerous conformity
assessment procedures to be applied.

Compliance of products to the ATEX Equipment Directive, through conformity assessment, takes a modular
approach, and is generally in two stages; design and production.

Temperature class relates to the hot surface ignition temperature of a particular explosive
atmosphere. It must not be exceeded by the temperature classification of the equipment
intended to be used in that atmosphere.

It lists a set of obligations and safety measures for employers, requiring the adoption of a coherent risk
assessment based strategy for the prevention of explosions. These obligations include:
• Generation of an explosion protection document, evaluating explosion risk, including: likelihood of the
presence of the explosive atmosphere, the presence of ignition sources (including electrostatic discharge),
identification of the substances and processes in use, definition of specific measures taken to safeguard
the health and safety of workers.

• Appropriate training and supervision for workers.

ASSOCIATED STANDARDS

• Classification of areas into zones and marking points of entry with safety signs.
Explosive atmosphere
consisting of a mixture with
air of flammable substances in
the form of gas, vapour or

combustible dust in air.

• Use of written instructions and permits to work.

GARAGE

• Special requirements for work equipment:– Equipment in service before 30 June 2003 may continue to be used after this date if it has been risk
assessed and the explosion protection document indicates it can be safely used.
– Equipment brought into service after 30 June 2003 must be CE marked as compliant with the
94/9/EC ATEX (Equipment) Directive.
• Due consideration of explosion protection measures, encompassing issues such as:

In the UK the 99/92/EC ATEX workplace Directive will be implemented as The Dangerous Substances and
Explosive Atmospheres Regulation 2002 (DSEAR). These regulations will also include the safety aspects of
the 98/24/EC Chemical Agents Directive, resulting in flammable and dangerous substances being covered
by a single set of regulations, thus reducing the volume of legislation covering this area.
