HP Jet Fusion 4200 Product Documentation Site Preparation Manual page 11

NOTE: An explosion-protected vacuum cleaner certified for collection of combustible dust is required for
cleaning. Take measures to mitigate material spillage and avoid potential ignition sources such as ESD
(ElectroStatic Discharges), flames, and sparks. Do not smoke nearby. Do not manipulate covers, isolation and
equipment filtering enclosures beyond what is specified in the maintenance chapter of the user guide.
Can the printer and processing station be installed in the same room as other
equipment?
The printer and processing station can be installed in the same room as other printers or equipment in general,
but they should be installed away from other equipment that could create a combustible dust cloud or metallic
dust during operation.
When installing the printer in a room with other equipment, it is important to know whether the other equipment
requires an exclusion zone around it, as this is an indicator of a potential hazardous location or ATEX-classified
location. In this case, follow the manufacturer's recommendations and material Safety Data Sheets about how
much space needs to be left around the equipment, and do not locate the printer and processing station inside
its exclusion zone. Follow your Environmental, health and safety processes and procedures.
Notice that we are referring to a combustible dust cloud. Operation does not need to be 100% dust free: any
dust quantity under 30 g/m³ is considered non-combustible. As a general indication, most market-available 3D
printers do not create combustible dust clouds during normal operation, therefore most printers can be installed
close to our system without any problem, following only the recommendations of both systems in terms of
space needed for access to doors, maneuverability, and so on. Some material management systems can create
a hazardous or ATEX-classified location, so always check the documentation of your other equipment to assess
the potential risks and decide what is the best setup for all your systems.
