Datasheet

If processing of this product generates dust or if extremely fine particulate is generated, obtain and
follow the safety procedures and equipment guides contained in Aluminum Association Bulletin
F-1 and National Fire Protection Association (NFPA) brochures listed in Section 16.
Use non-sparking handling equipment, tools and natural bristle brush. Cover and reseal partially
empty containers. Provide grounding and bonding where necessary to prevent accumulation of
static charges during metal dust handling and transfer operations (See Section 15).
Local ventilation and vacuum systems must be designed to handle explosive dusts. Dry vacuums
and electrostatic precipitators must not be used, unless specifically approved for use with
flammable/explosive dusts. Dust collection systems must be dedicated to aluminium dust only and
should be clearly labeled as such. Do not co-mingle fines of aluminium with fines of iron, iron oxide
(rust) or other metal oxides.
Dust collection systems must be dedicated to aluminium dust only and should be clearly labeled
as such. Do not co-mingle dust, fines or particulate of aluminium with dust, fines or particulate of
steel, iron, iron oxide (rust) or other metal oxides.
Avoid all ignition sources. Good housekeeping practices must be maintained. Do not use
compressed air to remove settled material from floors, beams or equipment.
Do not allow chips, dust, fines or particulate to contact water, particularly in enclosed areas.
Dust, fines or particulateaccumulation on the floor, ledges and beams can present a risk of
ignition, flame propagation and secondary explosions. Regularly clean building structures,
equipment and machinery to avoid accumulation of dust, fines or particulate that could become
airborne.
Requirements for Processes
which Generate Dusts or Fines
Small amounts of beryllium (<0.0001% or <1 ppm) can be present in aluminium alloys either from
naturally occurring beryllium in aluminium ore or as a alloying element in the aluminium recycling
stream. This beryllium does not present an health hazard during processing (grinding, cutting or
welding) of aluminium products. However, beryllium may concentrate in the dross formed when
aluminium scrap is remelted. Therefore, the potential for exposures to beryllium when handling
dross must be considered. Control of airborne dust levels would be critical in reducing or
eliminating this potential. For more information on the hazards associated with handling dross that
contains beryllium, refer to Arconic SDS No. 1013, Aluminium Dross with Low Beryllium. Copies of
this SDS are available on www.arconic.com or by calling [phone].
