	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion on contact with combustible substances or reducing agents.	NO contact with flammables. NO contact with reducing agents.	In case of fire in the surroundings, use appropriate extinguishing media.

AVOID EXPOSURE OF (PREGNANT) WOMEN!
	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 .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING

LEAD DIOXIDE

ICSC: 1001

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance BROWN CRYSTALS OR POWDER. Physical dangers No data. Chemical dangers Decomposes at 290°C. This produces oxygen and toxic fumes. Reacts violently with combustible substances, organic compounds, sulfur, hydrogen peroxide and phosphorus. This generates fire hazard.	Formula: PbO₂ Molecular mass: 239.2 Decomposes at 290°C Density: 9.38 g/cm³ Solubility in water: none

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 A harmful concentration of airborne particles can 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, encephalopathy (for example, convulsions), peripheral nerve disease, abdominal cramps and kidney impairment. Causes toxicity to human reproduction or development.
