No modifications should be carried out to any item of
COMMANDO
®
equipment
without the prior written approval of HCCE Ltd
Any components replaced must be to equal standards as the original equipment. As
such it is recommended that any such components are sourced directly from HCCE
Ltd.
Cleaning and Jetting Activities
– High Pressure Water Jets.
High pressure jetting and cleaning are by nature tasks involving significant hazards,
specifically due to the pressure and flow of water generated by
COMMANDO
®
units.
High Pressure Jets can be highly dangerous if subject to mis-use.
It is critical therefore that such activities are only carried out by suitably trained and
competent operators in controlled environments.
It is essential that a full risk assessment, and method statement if required, are in
place to cover all tasks. Specifics to consider within these include:
o
The machine must not be misused in any way, nor any hazardous areas
accessed, for example by directing the water jet at other person or animals.
o
Nor should the equipment/jet be directed by the operator at himself, for
example used for cleaning the operator or his clothing.
o
The machine should only be used in a safe location away from other persons
not involved in the activity and a safe working area should be established with
other persons kept away and clear of the hazard area.
o
The machine should only be located in well ventilated areas where exhaust
fumes can safely disperse.
o
The machine should not be left unattended where there is the possibility of
access or operation by unauthorised persons.
o
“Hold to Run” controls, notably the lance trigger or foot pedal, must never be
wedged or tied in their open/ operating positions.
o
Only use hand-held lances of the correct type, design and length
– normally a
minimum length of 75cm, below which particular requirements apply (refer to
BS EN 1829
– 1, Section 5.3.2.2).
The need for personal protective equipment (PPE) should always be considered as
part of the assessment. As a minimum it is suggested that this should include the
requirement for eye/face protection and the wearing of waterproof clothing. Plus
potentially hearing protection, safety/waterproof footwear, hard hat, hi - visibility
garment and gloves depending on the task and the actual equipment used.
Hoses, hose lines, connectors
Only high pressure hoses, spraying devices and accessories rated at or above the
capacity of the machine should be used. In the case of higher pressures of > 350
bar, hoses, hose lines, connectors and their use should comply with BS EN 1829 -2.
The use of connector safety devices (restraints) across connections to restrain the
hose ends should the connector, swage or hose end fail is recommended (and is
mandatory for machines with a drive input exceeding 40kW or a working pressure
exceeding 500 bar where significant presence of persons is foreseeable) .
