EGIONELLA
Water systems in buildings have been associated with
o
utbreaks of Legionnaires’ Disease, particularly in health
care facilities where occupants are significantly more
susceptible to infection.
In recognition of the risks in hospitals, a Code of Practice
for the Control of Legionella in Health Care premises has
b
een issued by the Department of Health (1991). Codes
of Practice applicable to other premises have been
published by other organisations, principally the Health
a
nd Safety Executive (HS)(G70) and the Chartered
Institute of Building Services Engineers (CIBSE, TM13).
All Codes of Practice draw attention to the design and
operation of water systems with reference to avoidance of
factors that favour colonisation by Legionella bacteria.
These factors include stagnation, lukewarm conditions
(20°C to 45°C) and the accumulation of debris, scale and
corrosion in the base of tanks and calorifiers.
The MAXXflo range has a Legionella flushing programme
