3. SAFETY
3.1 General Safety Indications
Improper use of pumps and high pressure systems, and the non-compliance with installation and maintenance
instructions may cause severe injury to people and/or damage to property. Anyone assembling or usinge high pressure
systems must possess the necessary competence to do so, should be aware of the characteristics of the components
assembled/used, and must take all precautions necessary to ensure maximum safety in any operating condition. In the
interest of safety, both for the Installer and the Operator, no reasonably applicable precaution should be omitted.
3.2 High pressure unit safety requirements
1. The pressure line must always be equipped with a safety valve.
2. High pressure system components, in particular for those units working outside, must be adequately
protected against rain, frost and heat.
3. The electrical control system must be adequately protected from water spray, and must comply with the
specific regulations in force.
4. High pressure hoses must be properly sized for maximum operating pressure of the system and always and only
used within the operating pressure range specified by the hose manufacturer. The same rules should be observed
for all other auxiliary systems affected by high pressure.
5. The ends of high pressure hoses must be sheathed and secured to a solid structure to prevent dangerous
whiplash in case of bursting or broken connections.
6. Appropriate safety guards must be provided for the pump transmission systems (couplings, pulleys and belts,
auxiliary drives).
3.3 Safety During Operation
The working area of a high pressure system must be clearly marked. Access must be prohibited to un-authorized
personnel and, wherever possible, the area should restricted or fenced. The personnel authorized to access this area
should first be trained, and informed about the risks that may arise from failures or malfunctions of the high pressure unit.
Before starting the unit, the operator must check:
1. That the high pressure system is properly powered (see paragraph 9.5).
2. That pump intake filters are perfectly clean; we advise the use of a device that indicates the filters clogging level.
3. Electrical parts are adequately protected and in perfect condition.
4. The high pressure hoses do not show apparent signs of abrasion, and that fittings are in perfect shape.
Any fault or reasonable doubt that may arise before or during operation should be promptly reported and verified by
competent personnel. In these cases, pressure should immediately be released and the high pressure system stopped.
3.4 General Procedures For Using Nozzles
1. The Operator must always place his own and other worker’s safety before any other interest; his and should always
be governed by good sense and responsibility.
2. The Operator must always wear a helmet with a protective visor, waterproof clothing, and appropriate boots capable
of guaranteeing grip on wet pavement.
