International Chemical Safety Cards LEAD ICSC: 0052 Lead metal Plumbum Pb Atomic mass: 207.2 (powder) ICSC #    0052 CAS #     7439-92-1 RTECS # OF7525000 October 08, 2002 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: use appropriate extinguishing media. EXPLOSION Finely dispersed particles form explosive mixtures in air. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. EXPOSURE See EFFECTS OF LONG-TERM OR REPEATED EXPOSURE. PREVENT DISPERSION OF DUST! AVOID EXPOSURE OF (PREGNANT) WOMEN!  •INHALATION Local exhaust or breathing protection. Fresh air, rest.  •SKIN Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Safety spectacles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Abdominal pain. Nausea. Vomiting. Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Give plenty of water to drink. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment. Personal protection: P3 filter respirator for toxic particles. Separated from food and feedstuffs and incompatible materials . See Chemical Dangers. R: S: SEE IMPORTANT INFORMATION ON BACK ICSC: 0052 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994.

International Chemical Safety Cards LEAD ICSC: 0052 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: BLUISH-WHITE OR SILVERY-GREY SOLID IN VARIOUS FORMS. TURNS TARNISHED ON EXPOSURE TO AIR. PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: On heating, toxic fumes are formed. Reacts with oxidants. Reacts with hot concentrated nitric acid, boiling concentrated hydrochloric acid and sulfuric acid. Attacked by pure water and by weak organic acids in the presence of oxygen. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.05 mg/m³; A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued; (ACGIH 2004). MAK: Carcinogen category: 3B; Germ cell mutagen group: 3A; (DFG 2004). EU OEL: as TWA 0.15 mg/m³; (EU 2002). OSHA PEL*: 1910.1025 TWA 0.050 mg/m3 See Appendix C *Note: The PEL also applies to other lead NIOSH REL*: TWA 0.050 mg/m3 See Appendix C *Note: The REL also applies to other lead NIOSH IDLH: 100 mg/m3 (as Pb) ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and by ingestion. INHALATION RISK: A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the blood , bone marrow , central nervous system , peripheral nervous system and kidneys , resulting in anaemia, encephalopathy (e.g., convulsions), peripheral nerve disease, abdominal cramps and kidney impairment. Causes toxicity to human reproduction or development.
