SAFETY REGULATIONS NF10
Disregarding Dantherm Filtration safety regulations entails a heavy safety risk.
Maintenance.
Maintenance must be performed to Dantherm Filtration maintenance directions.
Open fire, sparking or other form of heat generation such as: Welding, grinding, boring/drilling or
smoking etc. may not take place closer than 3 metres to filters, fans, pipe components, waste containers,
etc. working with explosive atmosphere, such as dust laden air.
It must be ensured that cleaning be performed on and around the system components to prevent
inflammable and explosive dust waste from igniting and causing heavy damage.
To prevent static electricity generation in systems with an inflammable and explosive atmosphere, it must
be ensured that such systems with connected ducts etc. be duly earthed.
Maintenance work may not commence until the total system has stopped properly, and the power supply
cut in a safe manner, for instance by locking the main switch.
Inspection inside the system by opening inspection doors and similar may not be performed until after the
usual cleaning periods have been run, until filters are free of dust accumulation, and dust/waste has been
carried to silo/waste bin.
In this connection, it must be checked whether the filter regeneration has been adequate, by examining
the residual dust accumulation on the sleeves.
Inspection by opening inspection doors and similar may be performed only when personal safety
equipment, adapted to the particular conditions, is used.
If a movable ladder is used for the work, the ladder must be secured properly for stability before
commencing the work.
Service and Repair.
Service and repair may be performed by specially trained staff only.
Before any work is begun, the energy supply must be cut by the main switch, and it must be ensured that
no unintended restart may occur, for instance by locking the main switch. Accumulated energy, such as
in a compressed air system, must also be interrupted, possibly discharged altogether, before commencing
the work.
For service and repair work making it necessary to stay in dust laden air, for instance in the filter, as a
minimum the following safety equipment must be used. For toxic dust, supplemented by own special
equipment, the following must be used:
