General safety reQuIrements
The explosion relief assembly, where fitted to the dust collector, is not
suitable for use with dusts that are classified as poisonous, corrosive, irritant,
carcinogenic, teratogenic or multigenic unless the dust released during the
explosion venting process can be contained to a safe level.
In order to ensure the required venting efficiency is maintained, the explosion
relief assembly, if fitted to the collector, should not be obstructed in any way.
It may be necessary to provide a facility to shut down the equipment in the
event of an explosion (where collectors are fitted with explosion relief panels).
The signal should be taken from the bursting panel detection device.
Part of the risk assessment on possible ignition sources for dust and gas
mixtures with very low MIE, has considered the electrostatic risk from cone
discharges. Here the basis of safety is based on using a conductive bin, dusts
with a median particle size of less than 400µm and advising frequent emptying.
You may wish to consider the use of a sprinkler system when handling explosive
or flammable materials.
None of the fan assemblies can be considered to be a fully sealed design,
indeed most are arranged with either an open inlet or an open outlet. For this
reason, the internal and external atmospheres can be considered the same in
terms of any potentially hazardous classification.
Standard fan assemblies should not exceed 3000 rpm (50 Hz supply) on
systems fitted with an inverter drive.
The filtration media is suitable for filtering particulate only (and not gas).
Some applications are prone to risk of fire. This risk can be reduced by pulse
cleaning and emptying the dust container regularly.
Any extinguishing technique and material used must be suitable for the
flammable nature of the dust.
A water sprinkler system can be fitted as a special option.
Materials handled by the dust collector may be hazardous (e.g. toxic). Conduct
a Risk Assessment to ensure correct technique is employed.
The dust collector should be cleaned and put into a safe condition prior
to decommissioning. All equipment decommissioning/removal is to be
executed in a manner consistent with applicable codes, regulations and sound
engineering practice.
