Safety Precautions / Remaining Risks

Qualified personnel should use proper care, procedures and tools when operating, maintaining or repairing this equipment in order
to prevent personal injury and/or property damage . The warnings listed below are to be used as guidelines only .
WARNING: Evaporative cooling equipment is considered as "Partly completed machinery" . "Partly completed machinery" is
a totality which almost forms a machinery but in itself cannot fulfil any particular function . The considered cooling
equipment is missing the components to safely connect it to the source of energy and motion in a controlled way .
The considered cooling equipment is custom made but is not designed to address the specific needs and safety
measures for a specific application . Each application requires a unique designed and integrated operational,
control and safety strategy that links all components of the installation and eventually a back-up system in a safe
and controlled way .
WARNING: This equipment should never be operated without fan screens and access doors properly secured, locked and in
place .
WARNING: For assembling or disassembling the unit or unit sections, please follow the rigging instructions or the
instructions on the yellow labels on the individual unit sections .
WARNING: During maintenance operations, the worker must use adequate personal protection equipment (PPE - A
minimum, but not limited list of PPE are safety shoes, glasses, gloves, respiration protection, helmet) as
prescribed by local authorities .
WARNING: For any exceptional, non routine work to be carried out, protection and adequate safety measures should be
considered and a Last Minute Risks Assessment (LMRA) must be made by an authorized person in accordance
with safety requirements of the country .
WARNING: A lock-out / tag-out procedure, integrated with the Process Control System, must be foreseen by the
customer . Before performing any type of service or inspection of the unit, make certain that all power has
been disconnected and locked in the "OFF" position .
WARNING: The top horizontal surface of any unit is not intended to be used as a working platform . No routine service
work is required from this area . For any exceptional, non routine work to be carried out on top of the
unit, use ladders, PPE and adequate safety measures against the risk of a fall, in accordance with safety
requirements of the country in question .
WARNING: The recirculating water system may contain chemicals or biological contaminants including Legionella
Pneumophila, which could be harmful if inhaled or ingested . Direct exposure to the discharge airstream
and the associated drift generated during operation of the water distribution system and/or fans, or mists
generated while cleaning components of the water system, require respiratory protection equipment
approved for such use by governmental occupational safety and health authorities .
WARNING: To avoid water and air contamination as a result of biological fouling, the cooling equipment must be
maintained in accordance, but not limited to the operating and maintenance instructions . All local
legislation related to evaporative cooling equipment must be respected .
WARNING: Accessories like platform and ladders are optional . In case these options are not taken in consideration, the
customer must design the installation to comply with local safety and access requirements and legislation .
