2. Safety
2.1
Intended Use
•
For double-walled pipe/fittings with an interstitial space that is suf-
ficiently pressure resistant
•
The leak detector alarm pressure must be at least 1 bar higher
than the maximum feed pressure in the product-transporting pipe.
•
Grounding/equipotential bonding in accordance with applicable
regulations

.
•
Tightness of the leak detection system according to section 7.3.4.
•
Leak detector installed outside of the explosive area.
•
Lead throughs into and out of the manhole chamber for connection
lines must be closed gastight.
•
Leak detector (electric) cannot be turned off.
•
Based on the use of air as leak detection medium, the following
points must be observed for conveyed media with a flash point
≤ 60 °C (Germany ≤ 55°C according to TRGS 509 and 751):
o
Explosive vapor-air mixtures must be assigned to temperature
code T1 to T3 and gas group II A or II B.
o
The inner wall must not be permeable for media that can lead to
the development of explosive vapor-air mixtures.
o
It must also be noted that in case of a leak in the inner pipe, air
is pressed into the conveyed product. This must be considered
when evaluating explosion protection of pumps/fittings along
the length of the pipe run.
•
Section 3.4.5 must be complied with.
Any claims arising from misuse are excluded.
2.2
Obligation of the Operating Company
The leak detector DLR-P is used in a commercial environment. The
operating company is therefore subject to statutory occupational safe-
ty obligations.
In addition to the safety instructions in this documentation, all appli-
cable safety, accident prevention and environmental regulations must
be adhered to. In particular:
-
Compiling a risk assessment and implementing its results in a di-
rective
-
Performing regular checks as to whether the directive is in com-
pliance with the current standards
-
The directive includes, among others, how to react to an alarm
that might arise
-
Arranging for an annual functional check
