In
recognition of his research work
in helping to understand Legionella
and controlling it as an environmental
pollutant, Clive Broadbent was honoured
with the award of Member of the Order
of Australia.
Evidence
of this contribution to society is
found in the many research-based
publications Clive has produced and
in his work as chairperson for a
number of standards setting committees.
Chief
among these standards is the Australian
standard AS/NZS 3666 : Air-handling
and water systems of buildings – Microbial
control. Part 1 (Design, installation
and commissioning) and Part 2 (Operation
and maintenance) of this standard
set out requirements in Australia
when a prescriptive approach is needed
for microbial control in building
services. Part 3 (Performance-based
maintenance of cooling water systems)
has been developed to provide a risk
management option. It covers the
need for water treatment with appropriate
operating limits and other assessment,
control and monitoring strategies
to help create a low risk environment
within the cooling water system.
The standard has been incorporated
into legislation in most jurisdictions
in Australia.
To
better serve the microbial control
performance requirements at large
installations, AS 5059 entitled “Power
station cooling tower water systems – Management
of Legionnaires’ disease health risk” was
developed. This standard sets out
an advanced risk management methodology
that includes all procedures set
out in AS/NZS 3666.3. Although focussed
on systems at power stations, the
approach is useful for systems of
any size and has proven to be comprehensive
in application.
Clive
Broadbent has presented technical
papers on the full suite of standards
at many conferences within Australia,
the USA, the UK, Singapore, New Zealand,
Hong Kong, Germany, and at other
European forums.
Clive
Broadbent & Associates Pty Ltd has
used all these standards in developing
risk management plans for client
applications as diverse as oil and
gas refineries, large commercial
office buildings, university campuses,
paper manufacturing plants, coal
mines and several power stations.
