Natural Gas Supply Considerations

If the pneumatic system is connected to natural gas, the pneumatic control system constantly
bleeds a small amount of the natural gas into the area around the SVI II ESD. Also, during a vent
cycle (actuator pressure relief), natural gas from the actuator is released into the area around
the SVI vent port. Consider both sources of natural gas when evaluating the Hazardous Classifi-
cation for the area (See GEA18946 Masoneilan SVI II ESD Smart Valve Interface with SIL3 Emer-
gency Shutdown PST Controller Installation and Maintenance Manual for further discussion on
installing an SVI II ESD in a natural gas environment).

Remote piping of the actuator venting is possible to reduce the amount of natural gas released
into the area around the SVI II ESD (See GEA18946 Masoneilan SVI II ESD Smart Valve Interface
with SIL3 Emergency Shutdown PST Controller Installation and Maintenance Manual for further
discussion on installing an SVI II ESD in a natural gas environment). Installing remote actuator
vent gas piping does not capture all gas emitted. A small amount of natural gas still bleeds con-
stantly in the area around the SVI II ESD. Consider the bleeding and releasing of natural gas when
evaluating the Hazardous Clarification for the area.

NOTE

Area classification is the responsibility of the end user.

The interior of the SVI II ESD is positively pressurized with supply medium. Appropriate safety
measures must be taken to handle pressurized natural gas that may enter the electrical conduit
or cable system.

WARNING

Do not remove the instrument cover or connect to an electrical
circuit unless the power is disconnected. Natural gas will escape
into the surrounding atmosphere upon disconnecting any of the
pneumatic connections or removing any cover or pressure
containing component.

WARNING

EXPLOSION HAZARD - Do not disconnect equipment or remove
cover unless power has been de-energized or the area is know to
be non-hazardous.



Natural gas may be contained within the SVI II ESD. Even after
disconnecting the SVI II ESD from all the pneumatic connections
Natural Gas may still be present within the SVI II ESD.

WARNING

EXPLOSION HAZARD - Natural gas may escape from the SVI II ESD
upon removal of any cover or component.



Ensure the cover is correctly installed before putting this unit into
service.
