trough.

Combined storage / Labelling / Checks
4.1
Combined storage
Care must be taken that the stored substances cannot undergo dangerous reactions with
each other when stored together in/on the collection system. The combined storage
prohibitions given in the regulations must be observed (e.g. in TRbF 20, TRGS 514,
TRGS 515 … in Germany).
4.2
Markings
Areas in storerooms for storing different hazardous substances must be marked with the
appropriate hazard symbols. A hazardous substances register must also be kept.
4.3
Checks
The collection troughs of the collection systems must be checked regularly, at least every
two days, when in use for leaks, contamination, etc.
Checks must be documented.
The collection troughs of the collection systems must be thoroughly checked once per year
for signs of damage, corrosion, etc.
4.4
Maintenance
Any damage to the construction or paintwork must be remedied immediately so that the
construction remains intact and no corrosion can occur as a result of the damage to the
paintwork.
Damaged grids should only be replaced by grids of the same type and load-bearing
capacity.
Damage that considerably affects the functioning of the collection system as a whole must be
repaired by the manufacturer or and authorized specialist (in Germany a special firm as
per §19 WHG).
