2.3
Main hazards
2.3.1
Hazards due to hot, cold (cryogenic) or aggressive gases, or high pressure
The FLSE100-XT sender/receiver units are mounted directly on the gas-carrying pipeline.
On equipment with low hazard potential, e.g., non-toxic, aggressive or explosive gases,
gases not hazardous to health, uncritical pressure, moderate gas temperature (not hot,
very low/cryogenic), the installation or removal can be performed while the equipment is in
operation, however only as far as the valid regulations and equipment safety notices are
observed and suitable protective measures are taken. Special regulations that apply to the
plant must be observed.
2.3.2
Hazard through electrical equipment
2.3.3
Hazards through explosive or ignitable gases
FLSE100-XT sender/receiver units may be used in potentially explosive atmospheres only
according to the respective specifications.
WARNING:
Gas hazard
▸
Activities on equipment with increased hazard potential, e.g. by toxic,
aggressive, explosive gases, health endangering, higher pressure, high
temperatures, low temperature (cryogenic), have to follow legitimate regula
-
tions, general standards and guidelines as well as plant operator instruc
-
tions. Only authorized personnel with special qualification for fitting using
the “Hot Tapping” method may install the devices when the plant is in oper
-
ation (requirements on the qualification of the personnel, see
).
Otherwise, serious injuries might occur, e.g. poisoning, burns etc.
These persons must be trained and technically adept in “hot tapping”
installation work and must know and implement legal as well as generally
applicable regulations and in-house regulations.
▸
The express approval of the plant operator in written form is required for
installations on running equipment at all times. The plant operator carries
the responsibility for professional implementation alone. All safety
requirements relevant for the equipment must be observed as well as
essential and suitable protective measures taken. All regulations/special
regulations that can be applicable for the plant must be observed.
WARNING:
Danger through power voltage
▸
Disconnect power supply lines before working on power connections or
parts carrying power voltage.
▸
Refit any contact protection removed before switching the power voltage
back on again.
WARNING:
Hazards through explosive or ignitable gases
▸
In potentially explosive atmospheres, only use the version of the FLSE100-
XT sender/receiver units specified for such use (
).
▸
Observe the information on
running equipment (“hot tapping” method).
