SPECIFIC RESPONSIBILITIES
A comprehensive list of OHS responsibilities is provided in the document OHS Roles,
Committees and Responsibilities Procedure. A summary of the specific responsibilities
relevant to Cooling tower management is provided below:
5.1
FACILITIES AND SERVICES
Responsibility for the active management of all cooling tower systems rests with the
university’s Facilities and Services Division, including responsibility for legal
compliance with legislation relating to cooling tower systems, which is managed by
the division’s Occupational Health and Safety Unit.
5.2
THE MAINTENANCE PLANNER
Mechanical Services will work with relevant campus Manager, Maintenance
Operations, Property and Venues Branch representatives and Occupational Health
and Safety to ensure the registration, risk management, maintenance, testing and
auditing of cooling tower systems is carried out in compliance with this procedure
and with relevant government requirements.
5.3
MANAGER, MAINTENANCE OPERATIONS
On a day-to-day basis the relevant campus Manager, Maintenance Operations will
oversee registration renewals, changes and decommissioning, risk assessments,
risk management plans, maintenance and testing of systems and record keeping,
and will provide reports to the Maintenance Planner – Mechanical Services on these
matters and on auditing of systems.
5.4
PROPERTY AND VENUES SERVICES BRANCH
For cooling tower systems on Monash University property (or part thereof) that is
leased to a third party, Property and Venues Services Branch will take responsibility
for the day-to-day management, in accordance with these procedures, of
registrations, renewals, changes and decommissioning, risk assessments, risk
management plans, maintenance and testing of systems and record keeping, and
will report through to the Maintenance Planner – Mechanical Services on these
matters and on auditing of systems. In some instances Property and Venues
Services Branch may choose to delegate this day-to-day management to the tenant,
in which case this will be clearly stated in the lease agreement and Property and
Venues Services Branch will take responsibility for obtaining from the tenant all
paperwork relevant to the registration, risk assessment and plans, maintenance and
testing reports and audit reports. In addition, the Property and Venues Services
representative will ensure the tenant has provided the university with a statutory

Company Director or a person in charge. The Property and Venues Services Branch
representative will ensure these are filed in the university TRIM system on a monthly
basis. Property and Venues Services Branch will also notify the Maintenance
Planner – Mechanical Services if and when any new lease is finalised, amended
and/or terminated which includes cooling towers in the property.

COOLING TOWER SYSTEM RISK ASSESSMENT
Every cooling tower system must undergo a risk assessment and from this a grading from A
to D is granted to each tower. This grading determines the frequency of the maintenance
program applicable to that cooling tower system. A risk rating template to determine the risk
assessment for a new cooling tower or to reassess the risk assessment for a current cooling
tower is available at:
http://www.health.vic.gov.au/environment/downloads/0501001part2.pdf on Page 30.
While this template will determine the minimum risk rating applicable to a cooling tower
system, Facilities and Services can choose to allocate a higher risk rating to any or all of its
cooling tower systems.
A copy of the cooling tower risk assessment for each cooling tower system should be
forwarded to the Maintenance Planner – Mechanical Services and another copy filed on the
university’s TRIM filing system.
Responsibility
Relevant campus Manager, Maintenance Operations or Property and Venues Services
Branch representative
Availability

8.
COOLING TOWER SYSTEM RISK MANAGEMENT PLAN
8.1
DEVELOPING A RISK MANAGEMENT PLAN
A risk management plan must be developed for every cooling tower system on
Monash University property. The plan should be developed after completing the risk
assessment and grading of the tower (see step 3 above) and must be completed
within 12 months of the first registration of the cooling tower system. A risk
management plan must continue to exist at all times the cooling tower system is in
operation.
A risk management plan should contain a number of basic components, namely:
• Site and contact details;
• Assessment of each of the critical risks;
• Summary of the overall risk classification;
• Details of the system collected during the risk assessment process; and
• Attachments or reference to other documents such as operational plans,
shut-down procedures etc.

Whilst there is no prescribed format for a risk management plan the Department of
Health provides a template which can be used, or modified to use, in the
development of a risk management plan. A copy of this template, together with
guidelines on how to complete a risk management plan for cooling tower systems, is
available at:
http://www.health.vic.gov.au/environment/legionella/risk-plans.htm
The risk management plan must address five critical risks namely:
• Stagnant water, including lack of water recirculation in a cooling tower
system and the presence of dead-end pipework and other fittings in the
cooling tower system;
• Nutrient growth, including the presence of biofilm, algae and protozoa in a
cooling tower system, water temperature within a range that will support
rapid growth of microorganisms in a cooling tower system and the exposure
of the water of a cooling tower system to direct sunlight;
• Poor water quality, including the presence of solids
• Deficiencies in a cooling tower system, including deficiencies in the physical
design, condition and maintenance of the system;
• The location of, and access to, a cooling tower system or cooling tower
system, including the potential for environmental contamination of the
system and the potential for exposure of people to the aerosols of the
system
The plan must also address any matters raised in a report from any person engaged
by the owner of the land or the owner of the cooling tower system which refers to
control measures being inadequate or requiring improvement.
Set out the steps to be taken to ensure compliance with the maintenance, service
and testing requirements described in the Public Health and Wellbeing Regulations
2009 of a cooling tower system. For example, the plan will need to describe how
you will respond to an adverse microbiological test result e.g. detection of Legionella
or a high HCC result.
Risk Management plans must be reviewed annually, and a copy of the latest plan
forwarded to the Maintenance Planner – Mechanical Services.
Occupational Health and Safety may undertake periodic audits of cooling tower
system risk management plans.
Responsibility
Relevant campus Manager, Maintenance Operations or Property and Venues
Services Branch representative.
8.2
AVAILABILITY OF RISK MANAGEMENT PLAN
The risk management plan, once completed, must be made available to an
authorised officer of the Department of Health on request. The current plan should
be kept in a readily accessible place on each campus, with a copy placed on the
Facilities and Services intranet and in TRIM.
Responsibility
Relevant campus Manager, Maintenance Operations or Property and Venues
Services Branch representative.
Availability
Risk management plan:
• One copy in readily accessible place on relevant campus
• On Facilities and Services intranet
• In TRIM
