1.4.2 Safety Procedures
Safety procedures must be observed while working on the pump, or any high
pressure part of the installation. Service should only be performed by
qualified personnel.
• The high pressure water, 3,800 bar (55,000 psi) in waterjet cutting systems
should not be a cause for concern. Users must have due respect for these
pressures and use proper SAFETY PROCEDURES and SAFE WORK HABITS.
• Everyone associated with the waterjet cutting system must realize that the
force of the waterjet cutting stream can penetrate many dense or strong
materials.
• Keep all untrained people away from the waterjet cutting area. Use barriers
or partitions if needed.
• Safety glasses must be worn at all times in the waterjet cutting area.
• All EMERGENCY STOP buttons must be checked periodically. The normal
operating position is pulled out.
• To check: turn on power and activate the EMERGENCY STOP buttons by
pushing them in to see if the power goes off. Each device should be checked
on a specified schedule. Each time the device is checked, it must function or
be replaced before operating the system.
• Apply High Purity Goop (P/N 10084440) to all threaded high pressure
connections. All tubing, fittings and bolted connections should be torqued to
recommended values. Do NOT attempt to tighten or loosen a HP water fitting
when the circuit is pressurized, see High Pressure (HP) Piping Safety.
• All high pressure leaks must be repaired immediately.
• Inspect all equipment on a scheduled basis.
• Before performing any maintenance on the unit, MECHANICALLY LOCK
THE MAIN CONTROL POWER OFF, and assure the high pressure has been
bled off.
