6. LEGIONELLA/LEGIONNAIRE’S DISEASE:
All pressurised water jetting, spraying and cleaning equipment has the potential to produce
aerosols and if the water supply to the machine contains legionella bacteria, these bacteria
can become airborne within the jetting aerosol.
The attention of users is thus also drawn to the UK Health & Safety Executive “Approved
Code of Practice” L8 which details the precautions that employers are required to take in
respect of legionnaire’s disease including the needs to carry out a risk assessment; have an
appointed competent person; have in place a legionella control scheme; and review of
control measures.
7.
NOISE:
In normal operation the Commando washer powering the Dustguard unit generates noise
levels of typically 116dB.
Customers are advised that they should carry out their own noise survey with the machine in
place in its normal work environment to determine actual noise levels to which operators are
exposed and any precautions necessary.
8. OPERATING INSTRUCTIONS.
8.1 GENERAL
8.1.1
Before putting the Dustguard unit into operation it is vital to risk assess the
task and environment and formulate a plan/”Safe System of Work” which
ensures protection of all persons who could potentially enter the area of
operation including operators.
Any persons or properties directly affected by the spraying should be
notified prior to work commencing and measures taken to keep them clear
of hazard areas, for example using signage, barriers, and supervision/
monitoring.
High pressure jets are dangerous if subjected to misuse.
Care should be taken to ensure that animals and children are well away
from the working area.
The jet/spray must not be
directed at people,
animals, the machine itself, non-waterproof, fragile or electrical equipment,
or overhead electric cables.
8.1.2
It is essential that any person who is required to operate or use high
pressure water jetting equipment is trained and totally competent to use that
equipment. By the very nature of the equipment and the purposes for which
it is used, it is essential that only physically capable people use the
equipment.
