Explosion hazard
Take precautions to avoid the risk of explosion.
WARNING! Dust clouds can form explosive mixtures with air. Take precautionary measures against
s
tatic charges, and keep away from sources of ignition (hot surfaces, hot flames or gases, mechanical
sparks, electrical equipment, electromagnetic waves, exothermic reactions including self-combustion
of solids).
NOTICE: The equipment is not intended for hazardous locations or ATEX classified zones: ordinary
locations only
.
Take the following precautions:
● The customer takes full responsibility for assessing the customer's site according to the Explosion
P
rotection Document (EPD), Dust Hazard Analysis (DHA), or any required document of the local
jurisdiction of the country where the equipment is installed, to avoid the risk of explosion.
● Users and operators conducting cleaning operations must have training in explosive atmospheres
and associat
ed hazards, according to local laws and company requirements.
● Smoking, candles, welding, and open flames should be forbidden close to the equipment or material
s
torage area.
● Inside and outside the equipment should be cleaned regularly with an explosion-protected vacuum
cleaner t
o avoid dust accumulation. Do not sweep the dust or or try to remove it with a compressed-
air gun.
● An explosion-protected vacuum cleaner certified for collection of combustible dust is required for
cleaning. T
ake measures to mitigate material spillage and avoid potential ignition sources such as
ESD (ElectroStatic Discharges), flames, and sparks. Do not smoke nearby.
CAUTION: In case of a massive spillage, immediately clean the bulk of the spilled powder by using
conduc
tive, non-sparking scoops and soft brushes that have natural fiber bristles. Residual
amounts of material remaining after preliminary cleanup, shall be removed using an explosion-
protected vacuum cleaner.
● An explosion-protected vacuum cleaner compliant with the following normative specifications:
– Europe/International Electrotechnical Commission (IEC): Zone 22 or better, temperature Class
2
00°C (392°F) maximum.
– United States/National Electrical Code (NEC): Class II, division 2 or better, temperature Class
2
00°C (392°F) maximum.
– Suitable for conductive powder (IIIB and/or group F).
– Refer to the material safety data sheet (MSDS) and meet local regulations.
– Recommended equipment fitted with wet filter (vacuum with submerged flow inches inert liquid)
or High E
fficiency Particulate Air (HEPA) filter grade.
● Vacuum system required for maintenance operations and general cleaning. Recommended
specifications:
– Air flow > 250 m³/h (150 cfm)
