NO contact with acid(s) , alcohol , oxidants and water . Dry sand, special powder. NO water. NO carbon dioxide, foam. EXPLOSION Finely dispersed particles form explosive mixtures in air. Risk of fire and explosion on contact with acid(s) , alcohol , oxidants and water . Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Local exhaust or breathing protection. Fresh air, rest.  •SKIN Protective gloves. Rinse skin with plenty of water or shower.  •EYES Safety goggles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Do not eat, drink, or smoke during work. Rinse mouth. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into covered and dry containers. (Extra personal protection: P2 filter respirator for harmful particles).

International Chemical Safety Cards ALUMINIUM POWDER ICSC: 0988 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: SILVERY- WHITE TO GREY POWDER . PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: Reacts with water and alcohols , and violently with oxidants , strong acids , strong bases , and chlorinated hydrocarbons causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV: (as Al) 5 mg/m³ as TWA (pyroforic powder) (ACGIH 2000). TLV: 10 mg/m³ as TWA (metal dust) (ACGIH 2000). OSHA PEL: TWA 15 mg/m3 (total) TWA 5 mg/m3 (resp) NIOSH REL: TWA 10 mg/m3 (total) TWA 5 mg/m3 (resp) NIOSH IDLH: No data ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation . INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Lungs may be affected by repeated or prolonged exposure to dust particles. The substance may have effects on the nervous system , resulting in impaired functions . PHYSICAL PROPERTIES Boiling point: 2327°C Melting point: 660°C Density: 2.7 g/cm3 Solubility in water: none reaction , Auto-ignition temperature: 590°C ENVIRONMENTAL DATA N O T E S Other UN number: UN1309 Aluminium powder, coated, Hazard class 4.1, Pack group II.
