PRESSURE LEAK DETECTOR
DLR-GS ..
- 9 -
If work is performed in areas in which an explosive atmosphere must
be expected, the minimum required equipment is as follows:
Suitable clothing (risk of electrostatic charge)
Suitable tools (in accordance with EN 1127)
Suitable combustible gas indicator calibrated to the existing vapor-
air mixture (work should be performed only at a concentration of
50 % below the lower explosion limit)
2
Measuring equipment to determine the oxygen content in the air
(Ex/O-meter)
2.5 Fundamental
Hazards
DANGER
From electric current
When working on the leak detector, it must be disconnected from the
power supply unless stated otherwise in the documentation.
Comply with relevant regulations regarding electric installation,
explosion protection (e.g. EN 60 079-17), if necessary, and accident
prevention.
DANGER
From explosive vapor-air mixtures
Ensure there is no gas present prior to performing work
Comply with explosion regulations, e.g. BetrSichV (and/or directive
1999/92/EC and the laws of the respective member states resulting
therefrom) and/or others.
DANGER
From working in shafts
The leak detectors are mounted outside the manhole chambers.
Pneumatic connection is usually performed inside the manhole cham-
ber. Therefore, the chamber must be entered for mounting.
Before entering, the corresponding protective measures must be
taken and it must be ensured that no gas and sufficient oxygen are
present.
