Once the collector has reached the end of operational life it will need to be decommissioned.
During decommissioning, there is potential for exposure to the dust in the collector. Most dusts present safety and
health hazards that require precautions. Wear eye, respiratory, head and other protection equipment suitable for the
type of dust when performing any decommissioning activities.
LOCK-OUT all energy sources prior to performing any decommissioning activities on the equipment.
Electrical service must be performed by a qualified electrician.
Disconnection of compressed air must be performed by a qualified pipe fitter.
Disconnection of ducts must be performed by a qualified tinsmith or contractor.
1. Turn off the collector and Lock-Out all energy sources.
2.
Remove all filters from the collector and dispose of in a suitable fashion for the dust in the collector. (See Filter Replacement
for instructions). Close and secure front access doors after filters are removed.
3. Remove and empty the dust drawers of any residual dust.
4.
Disconnect compressed air supply from the collector and remove any associated pipe or fittings from the exterior of the
collector.
5. Disconnect electrical power from the collector and remove any associated conduit or hardware from the exterior of the
collector.
6. Seal the inlet and discharge openings of the collector with shipping covers to prevent residual dust from migrating from the
collector during transport for disposal.
7. Remove anchor bolts and hardware from the collector.
8.
Pick up the collector and place in a location suitable to prepare it for transportation. (See Lifting Information for lifting
