Material Safety Data Sheet
5. Fire Fighting Measures
5.1. Extinguishing media
DO NOT use halogenated fire extinguishing agents.
Metal dust fires need to be smothered with sand, inert dry powders.
DO NOT USE WATER, CO2 or FOAM.
Use DRY sand, graphite powder, dry sodium chloride based extinguishers, G-1 or Met L-X to smother fire.
Confining or smothering material is preferable to applying water as chemical reaction may produce flammable and explosive
hydrogen gas.
5.2. Special hazards arising from the substrate or mixture
Fire Incompatibility: Reacts with acids producing flammable / explosive hydrogen (H2) gas
5.3. Advice for firefighters
Fire Fighting
Alert Fire Brigade and tell them location and nature of hazard.
Wear breathing apparatus plus protective gloves in the event of a fire.
Prevent, by any means available, spillage from entering drains or water courses.
Use fire fighting procedures suitable for surrounding area.
Fire/Explosion Hazard
DO NOT disturb burning dust. Explosion may result if dust is stirred into a cloud, by providing oxygen to a large surface of hot
metal.
DO NOT use water or foam as generation of explosive hydrogen may result.
With the exception of the metals that burn in contact with air or water (for example, sodium), masses of combustible metals do
not represent unusual fire risks
because they have the ability to conduct heat away from hot spots so efficiently that the heat of combustion cannot be
maintained - this means that it will require a
lot of heat to ignite a mass of combustible metal.
May emit poisonous fumes.
May emit corrosive fumes.
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 aluminum 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.
