Following maintenance work on any part of the unit, the affected part of the installation shall be re-commissioned by
checking to ensure safe start-up and operation.
After a maintenance shutdown, isolation of the unit or interruption to the water or electrical supply an appropriately
qualified person shall conduct start up checks to confirm safe operation.
When a unit is being decommissioned it shall be physically disconnected from the water supply, purged and sealed.
Where possible components should be recycled in accordance with government regulations.
1.1.8 Operational Safety
AIRA AL Evaporative Coolers must not be operated until the unit has been commissioned by a qualified person. The
unit should not be operated if any safeguards, panels or controls have been removed, damaged or bypassed.
If the unit is not operating as intended turn off the unit at the wall switch and then isolate the power and water supply.
The unit should remain isolated until a qualified service technician has inspected the unit and resolved any issues.
1.1.9 Safety Points to Consider
•
What is the best and safest access to the roof and/or work areas?
•
If a worker is alone, who knows they are there and if they get into difficulty, how can they summon help? (Call
someone on the ground? Mobile phone? Etc.)
•
Has the roof section or structure been assessed to ensure that it can withstand the load of the appliance and
workers.
•
Does the worker have appropriate foot wear? (Flat sole jogger type is advisable.)
•
Are all power cables / extension leads safe and appropriately rated?
•
Are all ladders, tools and equipment suitable in good condition?
•
Where ladders are to be used, is there a firm, stable base for them to stand on? Can they be tied or secured in
some way at the top? Is the top of the ladder clear of electricity supply cables?
•
Is there a roof anchor to attach a harness and lanyard to? If so, instruction should be issued for the use of an
approved harness or only suitably trained people used.
•
Are all tools and materials being used, prevented from slipping and falling onto a person at ground level? Is the
area below the work area suitably protected to prevent persons walking in this area?
•
Does the work schedule take into account weather conditions, allowing for work to be suspended in high winds,
thunder storms/lightning or other types of weather giving wet, slippery surfaces?
•
Is there an on-going safety check system of harnesses, ropes, ladders and access/lifting equipment and where
they exist on roofs, anchor points before the commencement of work?
•
Is there a system which prevents employees from working on roofs if they are unwell or under the influence of
drugs or alcohol?
•
Are there any special conditions to consider i.e. excessive roof pitch, limited ground area, fragile roof, electrical
power lines?
•
Is the person conducting the installation and maintenance appropriately qualified and familiar with local authority
and Australian Standards.
