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, explo-
sion protection (e.g. EN 60 079-17), and accident prevention.
CAUTION:
From moving parts
If work is being done on the leak detector, it must be disconnected
from the power supply.
DANGER:
From explosive vapor-air mixtures
Explosive vapor-air mixtures can exist in the leak detector and in the
connection lines.
Ensure there is no gas present prior to performing work
Comply with explosion regulations, e.g., German Ordinance on Indus-
trial Safety and Health (Betriebssicherheitsverordnung, BetrSichV)
(and/or directive 1999/92/EC and the laws of the respective member
states resulting therefrom) and/or others.
DANGER:
From working in chambers
The leak detector is usually assembled in the open air, whereas the
assembly kit is usually assembled in manhole chambers. Therefore,
the chamber must be entered for assembly.
Before entering, the corresponding protective measures must be tak-
en and it must be ensured that no gas and sufficient oxygen are pre-
sent.
