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, explo-
sion protection (e.g. EN 60 079-17), if necessary, and accident pre-
vention.
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
chamber. Therefore, the chamber must be entered for mounting.
Before entering, the corresponding protective measures must be tak-
en and it must be ensured that no gas and sufficient oxygen are pre-
sent.
