EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE!

  • INHALATION

  • Local exhaust or breathing protection.
    Fresh air, rest.
  • SKIN

  • Protective gloves.

  • EYES

  • Safety spectacles.
    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 containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place (extra personal protection: P3 filter respirator for toxic particles).
    Separated from strong oxidants, aluminium, sodium, food and feedstuffs.
    Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
    RED TO REDDISH-YELLOW CRYSTALS (see Notes).

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:
    Reacts violently with strong oxidants, aluminium powder and sodium. Upon heating, toxic fumes of lead compounds are formed.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV (as Pb): ppm; 0.15 mg/m3 as TWA (ACGIH 1992-1993).


    ROUTES OF EXPOSURE:
    The substance can be absorbed into the body by inhalation and by ingestion.

    INHALATION RISK:
    Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

    EFFECTS OF SHORT-TERM EXPOSURE:


    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    The substance may have effects on the central nervous system, kidneys and blood , resulting in anaemia and impaired functions. Does cause serious reproductive toxicity in humans.
    PHYSICAL
    PROPERTIES
    Melting point: 888C
    Relative density (water = 1): 9.5
    Solubility in water, g/100 ml: none
    ENVIRONMENTAL
    DATA

    N O T E S
    The substance exists in two forms: at ordinary temperatures red to reddish-yellow crystals and yellow crystals stable above 489C. Litharge, massicot are other names of lead(II) oxide. Also consult ICSC # 0052 (Lead).
