10.3. Possibility of hazardous
reactions
Grinding, sanding, buffing and polishing operations may generate potentially explosive aluminum
dust, fines or particulate that must not be co-mingled with dust, fines or particulate of steel, iron,
iron oxide (rust) or other metal oxides. Vacuum and dust collection systems utilized for processing
aluminum must be placarded as follows:
WARNING – Aluminum Metal Only – Fire or Explosion Can Result with Other Metals.
Chips, fines, dust and molten metal are considerably more reactive with the following:
• Heat: Oxidizes at a rate dependent upon temperature and particle size.
• Water: Slowly generates flammable/explosive hydrogen gas and heat. Generation rate is greatly
increased with smaller particles (e.g., fines and dusts). Molten metal can react violently/explosively
with water or moisture, particularly when the water is entrapped.
Explosions can occur with coils of foil that have been submerged or partially submerged in water
for an extended period of time. Water can penetrate between the layers of foil, react with the
aluminium surface and generate heat and hydrogen gas. When the coils are removed from the
cooling effects of the water, rapid temperature increases can occur causing steam explosions
which result in the rupture of the coils and discharge of debris.
Coils of foil may be a potential hazard under the following conditions:
• Coil has been annealed (annealing removes residual oil that could prevent penetration of water)
• Foil is very thin gauge (5-9 µm thickness which increases surface area)
• Coil has been immersed for an extended period of time (several hours or more)
• Wetted coil has recently been removed from the cooling effects of the water
In such situations, the coils should be isolated (30 meters from any personnel) for at least 72 hours
as soon as possible after removal from the water. Coils making crackling sounds or emitting steam
should not be approached or transported in commerce. Wetted coils should not be charged into a
furnace for remelting until completely dry.
