International Chemical Safety Cards NICKEL ICSC: 0062 Ni Atomic mass: 58.7 (powder) ICSC #    0062 CAS #     7440-02-0 RTECS # QR5950000 EC #         028-002-00-7 October 17, 2001 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Flammable as dust. Toxic fumes may be released in a fire. Dry sand. NO carbon dioxide. NO water. EXPLOSION Finely dispersed particles form explosive mixtures in air. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. EXPOSURE PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!  •INHALATION Cough. Shortness of breath. Local exhaust or breathing protection. Fresh air, rest.  •SKIN Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Safety spectacles, or eye protection in combination with breathing protection. 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 Vacuum spilled material. Carefully collect remainder, then remove to safe place. Personal protection: P2 filter respirator for harmful particles. Separated from strong acids. Xn symbol R: 40-43 S: 2-22-36 SEE IMPORTANT INFORMATION ON BACK ICSC: 0062 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

International Chemical Safety Cards NICKEL ICSC: 0062 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: SILVERY METALLIC SOLID IN VARIOUS FORMS. PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: Reacts violently, in powder form, with titanium powder and potassium perchlorate, and oxidants such as ammonium nitrate, causing fire and explosion hazard. Reacts slowly with non-oxidizing acids and more rapidly with oxidizing acids. Toxic gases and vapours (such as nickel carbonyl) may be released in a fire involving nickel. OCCUPATIONAL EXPOSURE LIMITS: TLV: (Inhalable fraction) 1.5 mg/m³ as TWA; A5 (not suspected as a human carcinogen); (ACGIH 2004). MAK: (Inhalable fraction); sensitization of respiratory tract and skin (Sah); Carcinogen category: 1; (DFG 2004). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of the dust. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: May cause mechanical irritation. Inhalation of fumes may cause pneumonitis. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation exposure may cause asthma. Lungs may be affected by repeated or prolonged exposure. This substance is possibly carcinogenic to humans. PHYSICAL PROPERTIES Boiling point: 2730°C Melting point: 1455°C Density: 8.9 g/cm3 Solubility in water: none ENVIRONMENTAL DATA N O T E S At high temperatures, nickel oxide fumes will be formed. Depending on the degree of exposure, periodic medical examination is suggested. The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance. Card has been partly updated in April 2005.
