LEGIONELLA STATEMENT
BACKGROUND
There is a growing awareness, through education and publicity, of
LEGIONELLA (Legionnaires Disease). This is a respiratory disease,
contracted by inhaling small droplets of contaminated water.
Concerns have been raised with regard to the possibility that the water
supply system in road sweepers could be a breeding ground for Legionella
bacteria, which occur naturally in fresh water, sea water and moist natural
environments throughout the world. They do not become a health hazard
until they have multiplied.
The conditions that are conducive to the multiplication of Legionella
bacteria are:
• A water temperature between 20 ° C and 45 ° C.
Legionella bacteria cannot grow below 20 ° C.
Legionella bacteria cannot live above 60 ° C.
• The presence of sludge, rust, algae etc. in the storage tank
or filtration system.
• Direct sunlight.
RECOMMENDATIONS
The water dust-suppression system used on all Scarab sweepers is of a
TOTAL LOSS type i.e. there is no re-cycled water stored on the vehicle.
Provided that the water tank is replenished regularly with mains water, the
risk of the bacteria growing is low, however, it might be prudent to take the
following basic precautions:
• Drain the water system at the end of the working day,
especially in hot weather.
• Flush/clean out the water tank and filtration system
regularly to remove sludge, debris, algae etc.
• Ensure that, if the pipe runs have been modified, there are
no ‘dead legs’ (i.e. no water flow) where the bacteria
might grow.
After discussions with the UK Health & Safety Executive, the Scarab water
system, is considered to be LOW RISK as it does not have any heaters, is not
used for cooling and is not recycled.
The foregoing advice is for guidance purposes only. For further information
or advice it is recommended that you consult your local environmental
health authority.
