3.4.3 Note on explosion protection
NOTE
The operation/installation of a UNION combustion calorimeter does not produce
a hazardous area because combustible gas does not escape from the calorime-
ter and form an explosive atmosphere.
No combustible gas escapes from the UNION combustion calorimeter because:
•
in conformity with the intended use of the combustion calorimeter, the gas is
combusted in the device,
•
the gas supply in the device is shut off as soon as the flame in the burner
goes out or if the fan fails, and
•
the gas-conveying lines can be regarded as technically leak-proof on a con-
tinuing basis (compression fittings) or through a systematically recurring
testing of tubes and membranes described in the operating instructions.
All gas inputs in the combustion calorimeter are provided with solenoid valves.
The solenoid valves close automatically in the event of a fault during combus-
tion or ignition of the gas mixture.
The solenoid valves are closed in current-free state.
3.5 Safety precautions on the owner side
WARNING
•
The owner must provide suitable protective equipment for the combustion
calorimeter that can reliably prevent injuries to personnel, e.g., from escap-
ing gas.
•
Exhaust discharged process gas to a safe environment!
•
Tripping hazard from improperly routed supply lines!
