ATEX REQUIREMENTS
According to:
a) I-N97 CEN/SFG-I "ATEX-Guidance Sheet" and
b) FAREGAZ Positions on ATEX Topics (see abstracts below),
The Dosaodor-D odorizing system is classified as an "installation" according to clause 5.2.2 of the ATEX GUIDELINES - 4th
Edition – September 2012 (see abstract below), therefore it's not covered by Directive 2014/34/UE (ATEX I).
ATEX products included in the Dosaodor-D odorizing system have to be Ex-certified.
Dosaodor-D odorizing system complies with the Directive 1999/92/EC (ATEX II) and other applicable National standards.
Odorizing Systems (absorption and/or injection types) are designed as stand-alone skids or as part of pressure regulating
stations (ref.: EN 12186).
Dosaodor-D is delivered with its complementary parts, e.g. by-pass to activate the back-up absorption odorizing systems,
electrical equipment and other components to be installed in the field, ...
Relevant technical standards are released at national level (e.g. in Italy UNI 9463-1 and UNI9463-2), but odorizing systems are
installed under the responsibility of the user after a risk assessment (hazardous area classification, ...) and, any commissioning,
tests and adjustments carried out are under the responsibility of the user.
HAZARDS
WARNING
!
Failure to follow these instructions or to
properly install and maintain this equipment
could result in an explosion and/or fire
causing property damage and personal
injury or death.
Odorizing systems should be installed,
operated and maintained in accordance with
international and national applicable codes
and regulations. Only qualified personnel
shall install an odorizing system. Installation,
operation and maintenance procedures
performed by unqualified personnel may
result in unsafe operation.
This condition may result in equipment
damage or personal injury. If a leak develops
in the system, the escaping gas may
accumulate and become a fire or explosion
hazard. Immediately call qualified service
personnel should this arise. Hazards arising
from mis‑use and mis‑operating are:
•
Personal injury, equipment damage, or
leakage due to escaping gas or bursting of
pressure‑containing parts may result if the
equipment is installed where its capabilities
(PS and TS) can be exceeded or where
conditions exceed ratings of the adjacent
piping or piping connections.
•
Physical damage could result in breakage,
causing personal injury and property damage
due to escaping gas. Installing the equipment
where its capabilities, or those of any
downstream equipment, can be exceeded may
cause personal injury or property damage due
to bursting of pressure‑containing parts or
explosion of accumulated gas.
To avoid above hazards, install the
equipment where:
•
service conditions are within the capabilities
as described in this manual.
•
service conditions are within applicable local,
federal or national codes or regulations.
•
the unit is protected from exposure to physi‑
cal damage and/or corrosive substances.
•
suitable pressure‑limiting or pressure‑relieving
devices have been installed where pressure
supply is capable of exceeding the maximum
allowable downstream equipment pressure.
HANDLING
Careful, established transport and handling procedures shall
be followed to avoid any damage on the pressure containing
parts by shocks or anomalous stresses. The equipment is
self stiffened and standard lifting devices may be used for
handling. Special care must be taken to avoid damaging the
pressure accessories installed, including the Dosaodor-D
calibration cylinder tank.
PRESERVATION AND STORAGE
All surfaces of the Dosaodor-D pneumatic panel equipment
are delivered completely protected (paint or stainless steel
material). We recommend to store the equipment indoor, and
it is strongly advised to carry out below recommendations.
Upon delivery on site, the unit shall be completely inspected
for any damage caused by transportation. Repairs should
be carried out without delay to avoid paint scaling and rust
propagation. Inspection is also advised on the assembled
pressure accessories (valves, level indicator, etc).
