Qualification Of Personnel; Risk Assessment And Minimization - RMG TME400-VMF Operating Manual

Qualification of personnel

1.2.4.4.
Note
In general, the following is recommended for all persons working with or on
the TME400:
• Training / education for work in hazardous areas.
• The capacity to be able to correctly estimate dangers and risks when
working with the TME400 and all connected devices. Possible dangers
include components that are under pressure and consequences of in-
correct installation.
• Recognition of dangers that can arise from the flow medium that is
used.
• Training / education by RMG for work with gas measuring devices.
• Education / instruction in all national standards and directives to be
complied with for the work to be carried out on the device.

Risk assessment and minimization

1.2.5.
According to assessment by qualified employees of RMG, the TME400 is subject to
risks during its use. Risks can arise, for example, due to high pressures and occa-
sionally due to pressures that are too low. Work outside of the permissible tempera-
ture range can also lead to dangers. Impermissible current and voltage values can
trigger explosions in hazardous areas. The risk assessment requires an emptying
and ventilation of the pipeline for connection with installation and removal of a tur-
bine. Then and only then is it assured that there is not an hazardous gas mixture in
the pipeline. Naturally, work must only be carried out by trained personnel (see chap-
ter 1.2.4.4 Qualification of personnel), who are also trained to recognize suitable tools
and use them exclusively. The risks were summarized alongside development and
measures were taken to minimize these risks.
Measures for risk minimization:
All pressurized parts are designed in accordance with AD 2000 rules and regula-
-
tions, Pressure Equipment Directive, Annex 1
The complete pressure design has been inspected by TÜV Hessen
-
All pressurized parts have been manufactured with a material certificate; there is
-
an uninterrupted change of batch tracing of pressurized components
The mechanical properties of all relevant pressurized components have been
-
subjected to tension tests, notch impact bending tests and hardness tests
Non-destructive testing was also carried out: X-ray and ultrasonic inspection of
-
the meter housing for defective points in material, surface crack testing with mag-
netic powder and a color penetration process
