1. General notes
1.1 Safety
The relevant accident prevention regulations according to BGV C22 must be observed during all work.
Particularly when walking on the tanks, a 2nd person is required to secure the tank.
The relevant regulations and standards must additionally be taken into consideration during installation,
assembly, servicing, repair, etc. Relevant notes can be found in the corresponding sections of these
instructions.
During all work on the system or parts of the system, the entire system must always be rendered
inoperable and secured to prevent unauthorised reactivation.
GRAF offers an extensive range of accessories, all of which are designed to match each other and which
can be extended to form complete systems. The use of other accessories may lead to impediments to the
system's functional capability, therefore invalidating liability for resulting damage.
