g. Do’s and don’ts
Based upon several hazards a list of do’s and don’ts is given.
Perform a regular maintenance by disposing the dust in a regular fashion and
inspecting the cleaning mechanism on a regular basis at least once a month.
Return the installation in its original state after maintenance (fixing, closing
and bonding and grounding).
Check the grounding and bonding at least once a year.
The housing of the dust collector should never be changed or painted on the
inside with a non-conducting coating.
Vents should never be blocked or painted.
Use the original bursting panel types only.
Do not alter the vent area or vent location.
Vent ducts should never be altered.
Do not tamper with explosion protection systems such as explosion
suppression and explosion barriers as quick acting valve.
Use original equipment as filter cartridges, electrical equipment, rotary valves
etc..
Do not use non-conductive plastic hoses and pipes.
Prevent goods and forbid personnel to be near such a vent.
Never open the dust collector during operation.
After emptying the receiver bin, fix it as in the original state.
Keep the working place clean.
For any changes in the dust collector, safety system, process, product or dust
collector location consult the manufacturer.
h. Applications having a risk of sparks and fires
1. Good Housekeeping
Accumulation of potentially combustible dust, for example dust layers is
considered a potential ignition source. Failure to keep the dust collector
clean and empty the hopper / dust bins regularly will increase the risk of fires
and/or explosions.
2. EU Directive 99/92/EC.
A reinforced and/or vented dust collector must be used when handling dusts
that have the potential to form an explosive atmosphere. If a non-reinforced
and/or non vented dust collected is used on these applications then the end
user must ensure an equivalent, secure, and fool proof basis of safety, which
must be clearly documented in the end users Explosion Protection Document
in line with Article 8 of EU Directive 99/92/EC.
3. Self Heating Materials
Please note that some materials have the potential to self generate heat and
hence to become an ignition source, that could result in a fire and / or an
explosion. For this reason ferrous and non-ferrous materials should not be
extracted in to the same dust collector, as when combined they can create
a violent thermite reaction that would ignite a fire and/or explosion.
