TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.
NO contact with flammable substances. NO contact with reducing agents.
In case of fire in the surroundings: water spray.
EXPLOSION Risk of fire and explosion on contact with combustible substances and reducing agents.


EXPOSURE
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

LEAD DIOXIDE ICSC: 1001
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
BROWN CRYSTALS OR POWDER.

CHEMICAL DANGERS:
The substance decomposes on heating at 290C, producing oxygen and toxic fumes. Reacts violently with combustible substances, organic compounds, sulphur, hydrogen peroxide, and phosphorus, causing fire hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as Pb) 0.05 mg/m as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued; (ACGIH 2004).
MAK: (as Pb) (Inhalable fraction); Carcinogen category: 3B; Germ cell mutagen group: 3A; (DFG 2004).
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 when dispersed, especially if powdered.

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.
PHYSICAL PROPERTIES
Melting point (decomposes): 290C
Density: 9.38 g/cm
Solubility in water: none
ENVIRONMENTAL DATA
Bioaccumulation of this chemical may occur in plants and in mammals. It is strongly advised that this substance does not enter the environment.
NOTES
Depending on the degree of exposure, periodic medical examination is suggested. Do NOT take working clothes home.
Card has been partly updated in April 2005. See section Occupational Exposure Limits.
