3.3 Safety During Operation
The working area of a high pressure system must be clearly indicated. Access must be prohibited to non-authorized
personnel and, as far as possible, it must be restricted or fenced off. The personnel authorized to access this area must
be previously 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 unit is correctly fed (see paragraph 9.4).
2. That pump intake filters are perfectly clean; we advise to use a device that indicates the filters clogging level.
3. That electrical parts are adequately protected and in perfect condition.
4. That high pressure hoses do not show apparent signs of abrasion, and that fittings are in perfect shape.
Any anamoly or reasonable doubt that may arise before or during operation must be promptly reported and verified by
competent personnel. In these cases, pressure must be immediately released and the high pressure unit 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 actions should always
be dictated by good sense and responsibility.
2. The Operator must always wear a hard hat with a protective visor, waterproof clothing, and suitable boots
capable of providing a good grip on wet pavement.
Note: appropriate clothing will effectively protect against water spray, but it may not offer adequate protection against the
direct impact of water jets or sprays at a close distance. Some circumstances may require further protection.
3. It is good practice to work in teams of at least two Operators, able to provide mutual and immediate assistance if
needed, and to rotate their duties in case of long and demanding tasks.
4. Access to the work area that is within the water jets’ range must be absolutely prohibited; the area must be
free of objects that may be inadvertently hit by the pressurized jet, causing damage or dangerous situations.
5. The water jet must only and always be directed towards the work area, even during testing or preliminary
inspections.
6. The Operator must always pay attention to the trajectory of the debris removed by the water jet. If necessary,
adequate side guards must be provided by the Operator in order to protect anything that may be accidentally
exposed.
7. For no reason must the Operator be distracted during operation. The personnel that needs to access the
working area must wait for the Operator to suspend his work, and then immediately make his presence known.
8. For safety reasons, it is important that each member of the team is completely aware of the intentions and actions
of other team members in order to avoid dangerous misunderstandings.
9. The high pressure system must not be started and brought up to pressure unless each member of the team is in his
designated position, and the Operator has already directed the nozzle towards the work area.
3.5 Safety During System Maintenance
1. Maintenance of the high pressure system must be done within the time intervals indicated by the Manufacturer, who
is responsible for the entire unit’s compliance with the regulations in force.
2. Maintenance must always be carried out by specialized and authorized personnel.
3. Assembly and disassembly of the pump and its various components must be performed exclusively by authorized
personnel, using appropriate tools in order to avoid damage to components and connections.
4. To guarantee total reliability and safety, always use original spare parts.
