Horizontal downflow pleated cartridge dust collector
18
Workers must wear protective clothing and apparatus such as safety goggles, gloves, respiratory
equipment, etc. when working inside the collector.
Instructions in this booklet must be read and understood prior to performing tasks on the collector.
15.2 Electrical components
All electrical components must be shut down and main breaker locked to avoid any possible risk
of electrocution when handling or working on such components.
15.3 Explosive dusts
If the dust to be collected is naturally explosive or inflammable once inside the collector, an
explosion relief venting system and/or a fire extinguishing device will be required. If you have any
doubt as to the nature of the dust to be collected, call your A.Q.C. representative.
15.4 Anchors
All sections of the dust collector including the optional equipment must be bolted to the slab in
order for the unit to be stable and secured should an explosion occur or in case of high winds.
15.5 Interior installation
When a dust collector equipped with an explosion relief venting system is installed inside the
premises, the unit must be installed within 3 meters (10 feet) of an exterior wall and the explosion
vents has to be connected to an exhaust duct leading outside. This duct must be designed to
sustain the same pressure as the one within the dust collector.
If clean air is returned back into the premises, dispositions must be taken to exhaust the air back
outside should a filter be defective or any other possible failure. A safety after-filter should be
installed to protect the staff against accidental breathing of unfiltered dusts.
The air flow coming out of the collector should be headed away from the staff, offices, pedestrian
walkways and any other area accessible to people.
15.6 Spark producing activities
When the dust or particles to be collected are stocked within the collector or adjacent equipment,
there should be no welding process or any other spark or flame producing activities around
the collector until the system has been shut down and cleaned. If such operations have to be
performed, the filter elements have to be removed from the collector and stored in a dry area.
