WARNING
HAZARDOUS ENVIRONMENT
Risk of explosive atmosphere
.
Avoid electrostatic potential, especially on plastic
components. Adapters, isolation valves, or sealing rings that
are not compatible with process gasses will corrode and fail.
This failure may result in gas leaks, fire, explosion, or
projectiles.
De-energize all devices before placement or removal. To
prevent corrosion and failure, verify that all components are
compatible. Verify that hazardous materials, atmospheres, and
conditions have been removed or that relevant risk mitigation
measures have been implemented.
Installations and maintenance tasks performed in potentially hazardous areas must be
performed only after the area has been verified to be free of hazardous materials, atmospheres,
and conditions.
The following situations could cause a spark enough to ignite an explosion:
l
Potential of electrostatic discharge on plastic components, or
l
Removal or placement of an energized connection.
