1.0 SAFETY INFORMATION
The safe operation of this product is ensured only if it is installed, commissioned, used and maintained in an
appropriate way by qualified personnel in compliance with the operating instructions.
1.01 INTENDED USE
Verify that the actuator is suitable for the intended use and application by controlling:
‐
to have arranged an appropriate safety device which prevents, in case of malfunctioning of the actuator, any
hazardous overpressures or overtemperatures.
The OMC actuators are not intended to withstand external stresses which may be induced by the systems in
which they are inserted. The installer must take account of these stresses and take the appropriate measures.
1.02 ACCESS
Ensure a safe access and, if required, a safe working platform (with a suitable protection) before operating on the
product. Arrange the suitable lifting means, if required.
1.03 LIGHTING
Ensure a lighting which is suitable to the required type of work.
1.04 HAZARDOUS FLUIDS IN THE PIPE
Take account of the content of the pipe or anything it may have previously contained. Be careful to: flammable
materials, substances hazardous for the health, temperature extremes.
1.05 ENVIRONMENTAL SITUATIONS
Take account of: areas at risk of explosion, lack of oxygen (such as tanks, wells, etc.…), hazardous gases,
temperature limits, high or low temperature surfaces, risk of fire (for example during welding operations),
excessive noise, moving machines.
1.06 TEMPERATURE
Wait until the temperature normalizes after the interception to prevent any risks of burn or freezing.
1.07 SYSTEM
Take account of the possible effects on the whole expected working system.
May the intended measure put the other parts of the system or the personnel at risk?
Make sure that the shut-off valves are gradually activated in order to prevent any abrupt variations to the system.
1.08 PRESSURIZED SYSTEMS
Make sure that the pressure is isolated and discharged to the atmospheric pressure in safe conditions. Take
account of a double insulation (double block and vent) and the blocking or the labelling of the closed valves. Do
not consider the system depressurized even if the pressure gauge indicates zero pressure.
During the operation the valve is pressurized. Before performing any maintenance operation or action on
the flanges and closing caps, make sure that the line is depressurized (0 bar) and at ambient temperature.
