OPERATION
their functional requirements. It is therefore the customers responsibility to ensure
that sufficient time is allowed for the air flow to have ceased before cleaning is
initiated, fitting interlocks if necessary.
Before restarting the collector, the dust container, if fitted, should be checked for
dust quantity and emptied if necessary.
Refer to Controller manual, Publication IOM AK0303001, for further details.
Dust disposal
For safe handling of the dust container an assessment must be made
to satisfy the requirements of the European Directive 90/269/EEC on
manual handling.
Dust containers may require regular emptying. If the dust being handled
is explosive, then care should be taken to ensure that dust spillage is kept
to a minimum to avoid the creation of potentially explosive atmospheres
and secondary hazards.
Dust containers should be securely replaced and resealed prior to
collector restart. This is a good time to check the dust container for
damage, which may lead to a dust leak or flame emission in the rare
instance of an internal explosion.
