ATEX 94/9/EC Operating and Safety Instructions
Introduction
This Installation Sheet is applicable for regulators
and accessories being used in a potentially explosive
atmosphere under ATEX 94/9/EC requirements.
Marking
Marking of regulator and accessories shall be strictly
in accordance with the requirements of ATEX 94/9/EC,
and includes:
• CE and EX Mark
• Equipment Group II
• Equipment Category 2, as label
• Type of explosive atmosphere, GD
• Equipment protected by constructional safety “c”
• Maximum temperature in service “TX”
Selection
1. Ensure that the equipment is marked with the correct
equipment group, category, type of atmosphere
and temperature class according to hazardous area
classicationoftheareaofinstallation.
2. Ensure that the maximum temperature indicated
on the product nameplate does not exceed the
maximum temperature foreseen by the hazardous
areaclassication.
Installation
1. Ensure that the safety instructions are followed for
each regulator.
2. Ensure that only non-sparkling tools are used, as
per EN 1127-1, Annex A.
3. Ensurethatnofreeamesarepresentnear
the regulator.
4. Be protected against other hazards using adequate
gloves and glasses.
5. Ensure that no metallic shocks/impacts are made
to the regulator or the adjacent pipelines system
during installation.
6. Strictly follow the operating and safety instructions
provided for the regulator.
7. Whentheregulatoristohandlehotuidsoruids
where exothermic reactions may take place,
ensure that all the necessary measures are taken
so that the hot surface of the regulator cannot
provide a source of ignition to the surrounding
gas, vapor, mist or dust atmosphere (including a
periodical removal of the dust deposits from the
hot surfaces of the regulator).
8. Before putting into use or during the operation with
dangerousuid,ensurethatnoreleaseoftheuid
to atmosphere can take place.
9. Make sure that the pressure regulator is
connected to the local earthing system for the
electric continuity.
10. Ensure a proper grounding of the regulator to
mitigate the effects of lightning strikes.
