Filling and water control in Germany
According to § 2 “Specific obligations regarding filling and draining” of the Ordinance on
Installations for the Handling of Substances Hazardous to Water (Verordnung über Anlagen
zum Umgang mit wassergefährdenden Stoffen) from 31 March 2010, the following is
applicable additionally:
“The person filling or draining an installation for storing water-hazardous substances shall be
obliged to monitor this process and to make sure, prior to starting any work, that the required
safety equipment is in a proper condition. The admissible exposure limits of the installations
and safety equipment must be adhered to when filling or draining.”
ADJUSTING DIMENSION X
The tables of the manual issue 2 regarding the adjusting dimension
X
are based on a level
L
1
for the length of the filler line
to 20m
. Level
L
1
is the reference dimension for
X
.
If, for storing, filling, and handling water-hazardous substances, the filler line on the
installation is
longer than 20m
, the level
L
1
must be reduced:
Criterion:
•
Overrun volume in the filler line
•
the adjusting dimension
X
must be re-determined according to the special conditions
•
the admissible level with
L
max
of tanks according to
table 5
must not be exceeded, e.g. level
indicator maximum on the tank and on the level gauge, respectively
