SAFETY

3.1

General safety warnings

Improper use of pumps and high pressure systems as well as
non-compliance with installation and maintenance standards
can cause serious damage to people and/or property. Anyone
assembling or using high pressure systems must possess the
necessary competence to do so, knowing the characteristics of
the components that will assemble/use and take all precautions
necessary to ensure maximum safety in all conditions of use. In
the interest of safety, both for the Installer and the Operator, no
reasonably applicable precaution should be omitted.
3.2

Essential safety in the high pressure system

1. The pressure line must always be provided with a safety valve.
2. High pressure system components, particularly for systems
that operate primarily outside, must be adequately
protected from rain, frost and heat.
3. The electrical control system must be adequately protected
against sprays of water and must meet specific regulations in force.
4. The high pressure pipes must be properly sized for
maximum operating pressure of the system and always
and only used within the operating pressure range
specified by the Manufacturer of the pipe itself. The same
rules should be observed for all other auxiliary systems
affected by high pressure.
5. The ends of high pressure pipes must be sheathed
and secured in a solid structure, to prevent dangerous
whiplash in case of bursting or broken connections.
6. Appropriate protective casing must be provided in pump
transmission systems (couplings, pulleys and belts,
auxiliary power outlets).
3.3

Safety during work

The room or area within which the high pressure system
operates must be clearly marked and prohibited to
unauthorised personnel and, wherever possible, restricted or
fenced. Personnel authorised to access this area should first
be instructed how to operate within this area and informed
of the risks arising from high pressure system defects or
malfunctions.
Before starting the system, the Operator is required to verify
that:
1. The high pressure system is properly powered, see
chapter 9 par. 9.4.
2. The pump suction filters are perfectly clean; it is
appropriate to include a device indicating the clogging
level on all devices.
3. Electrical parts are adequately protected and in perfect
condition.
4. The high pressure pipes do not show signs of abrasion and
the fittings are in perfect order.
Any fault or reasonable doubt that may arise before or
during operation should be promptly reported and verified
by qualified personnel. In these cases, pressure should be
immediately cleared and the high pressure system stopped.
3.4

Rules of conduct for the use of lances

1. The operator must always place his safety and security
first, as well as that of others that may be directly affected
by his/her actions, or any other assessments or interests.
The operator's work must be dictated by common sense
and responsibility.
2. The operator must always wear a helmet with a protective
visor, waterproof gear and wear boots that are appropriate
for use and can ensure a good grip on wet floors.
Note: appropriate clothing will protect against sprays of water but
not from direct impact with jets of water or very close sprays. Addition-
al protections may therefore be necessary in certain circumstances.
3. It is generally best to organise personnel into teams of at
least two people capable of giving mutual and immediate
assistance in case of necessity and of taking turns during
long and demanding operations.
4. The work area jet range must be absolutely prohibited to
and free from objects that, inadvertently under a pressure
jet, can be damaged and/or create dangerous situations.
5. The water jet must always and only be pointed in the
direction of the work area, including during preliminary
tests or checks.
6. The operator must always pay attention to the trajectory
of debris removed by the water jet. Where necessary,
suitable guards must be provided by the Operator to
protect anything that could become accidentally exposed.
7. The operator should not be distracted for any reason
during work. Workers needing to access the operating area
must wait for the Operator to stop work on his/her own
initiative, after which they should immediately make their
presence known.
8. It is important for safety that all team members are always
fully aware of each other's intentions in order to avoid
dangerous misunderstandings.
9. The high pressure system must not be started up and run
under pressure without all team members in position and
without the Operator having already directed his/her lance
toward the work area.
