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.
3.5 Safety during system maintenance
1. High pressure system maintenance must be carried out
in the time intervals set by the manufacturer who is
responsible for the whole group according to law.
2. Maintenance should always be performed by trained and
authorised personnel.
3. Assembly and disassembly of the pump and the various
components must only be carried out by authorized
personnel, using appropriate equipment in order
to prevent damage to components, in particular to
connections.
4. Always only use original spare parts to ensure total
reliability and safety.
