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: powder, water spray, foam, carbon dioxide.
EXPLOSION


EXPOSURE
AVOID ALL CONTACT!

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 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.
Do not transport with food and feedstuffs.

LEAD CARBONATE ICSC: 0999
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS.

CHEMICAL DANGERS:
The substance decomposes on heating to 315C, producing toxic fumes of lead oxide. Reacts violently with fluorine, 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, hemolysis, encephalopathy (e.g., convulsions), peripheral nerve disease, kidney impairment. Causes toxicity to human reproduction or development.
PHYSICAL PROPERTIES
Melting point (decomposes): 315C
Density: 6.6 g/cm
Solubility in water, g/100 ml: 0.0001
ENVIRONMENTAL DATA
In the food chain important to humans, bioaccumulation takes place, specifically in plants and mammals. It is strongly advised not to let the chemical enter into the environment because it persists in 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 sections Occupational Exposure Limits, Emergency Response.
