2 HEALTH AND SAFETY RECOMMENDATIONS
Use caution when working on Veolia Water equipment. The following items are likely to present
possible hazards - chemicals, ion exchange resins, electricity, air pressure, water pressure, hot
water and hot surfaces. Please ensure personnel are familiar with these hazards and that adequate
precautions are maintained.
2.1 CHEMICALS
Chemicals used on Orion systems during normal use are
–
Salt which is added to the Brine Tank(s) for regenerating the softeners
Elgalite RU3 which is an organic acid cleaner for the Reverse Osmosis membranes
Elgalite LF12 which is an alkaline detergent also used to clean the Reverse Osmosis membranes
Refer to safety data sheets supplied with the above products and follow the safety instructions during
use.
2.2 ELECTRICITY
The unit must be properly earthed and the correct rated fuses should be fitted. Power should be
switched off at a remote isolator before commencing work on the equipment.
2.3 EMERGENCY SHUTDOWN
In an emergency the unit can be turned off at the door isolator, since the Shutdown command on the
HMI touch panel requires a pass key and takes time to activate.
2.4 AIR AND WATER PRESSURE
Veolia Water equipment operates at pressure and, where possible, this should be reduced before
commencing work. Normal protection from freezing should be taken, as ice inside pressure vessels
and pipework can cause rupture. Compressed air can be dangerous and care should taken with its
use.
2.5 HOT WATER AND HOT SURFACES
Whilst the ORION unit operates at ambient temperatures during normal operation, components from
the soft water break tank onwards (generally the stainless steel part of the unit) are periodically
elevated to 85
o
C to sanitise the system. When the unit is at elevated temperature a warning beacon
flashes to highlight this danger and care should be taken to prevent the risk of burning by touching
hot stainless steel surfaces, or scalding by opening valves etc.
