Risk Assessment And Minimization - RMG PGC 9300 Operating Manual

1.2.5

Risk assessment and minimization

According to assessment by qualified employees of RMG, the gas chromatograph
PGC 9300 is subject to risks during its use. Risks can also arise due to high pres-
sures and occasionally due to pressures that are too low. Work outside of the per-
missible temperature range can also lead to dangers. Impermissible current and
voltage values can trigger explosions in explosion-prone areas. The risk assess-
ment requires an emptying and ventilation of the pipeline for connection of a
PGC 9300. Then and only then it is assured that there is not an explosion-prone
gas mixture in the pipeline. Naturally, work must only be carried out by trained per-
sonnel (see chapter 1.2.4.4 Qualification of the user) who are also trained to rec-
ognize suitable tools and use them exclusively. These risks were summarized
alongside development and measures were taken to minimize these risks.
Measures for risk minimization:
- The maximum operating pressure and the permissible temperature range
are specified on the type plate of the device. Operation of the device is only
permitted within these specified ranges.
Danger
Work in explosion-prone areas
The following applies for work in explosion-prone areas (all zones):
- Only tools that are approved for Ex Zone 1 are permitted for maintenance
and repair tasks. Components can be damaged if you do not use suitable
tools.
The explosion protection is lost.
- Otherwise, work must only be carried out when there is not an explosive at-
mosphere.
- The risk of ignition due to impact or friction must be avoided.
- The wiring from and installation of the gas chromatograph PGC 9300 in ex-
plosion-prone areas must only be carried out by trained personnel in ac-
cordance with EN60079-14 and in observance of national regulations.
- Qualified persons must satisfy the definitions in accordance with
DIN EN 0105 or IEC 364 or directly comparable standards.
- Only trained and instructed personnel are permitted. Work on the measur-
ing system must only be carried out by qualified persons and inspected by
responsible qualified supervisors.
