FIRE & EXPLOSION	Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.		In case of fire in the surroundings, use appropriate extinguishing media.

AVOID ALL CONTACT!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation		Use local exhaust or breathing protection.	Fresh air, rest.
Skin		Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes		Wear safety spectacles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	Abdominal pain. Nausea. Vomiting.	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .

Formula: PbCO₃
Molecular mass: 267.2
Decomposes at 315°C
Density: 6.6 g/cm³
Solubility in water, g/100ml: 0.0001

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation and by ingestion. Effects of short-term exposure	Inhalation risk Evaporation at 20°C 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. This may result in anaemia, haemolysis, encephalopathy (for example, convulsions), peripheral nerve disease and kidney impairment. Causes toxicity to human reproduction or development.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation and by ingestion.

Effects of short-term exposure

Inhalation risk
Evaporation at 20°C 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. This may result in anaemia, haemolysis, encephalopathy (for example, convulsions), peripheral nerve disease and kidney impairment. Causes toxicity to human reproduction or development.

OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.05 mg/m³, as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans). MAK: carcinogen category: 2; germ cell mutagen group: 3A. EU-OEL: (binding): 0.15 mg/m³ as TWA

ENVIRONMENT
Bioaccumulation of this chemical may occur in plants and mammals. It is strongly advised not to let the chemical enter into the environment because it is persistent.

NOTES
Depending on the degree of exposure, periodic medical examination is suggested. Do NOT take working clothes home.
