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 to be assembled/used and taking all
the necessary precautions 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
unauthorized personnel and, wherever possible, segregated
or fenced to ensure restricted access. Personnel authorized
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.
5. In relation to the application, use and environmental
conditions, during the operation the outer surfaces of the
pump may reach high temperatures.
Therefore we recommend to take precautions to avoid
contact with hot parts.
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 effectively protects against splashes
but not so effectively against direct impact with very close water
spray or splashes. Additional protections may therefore be
necessary in certain circumstances.
