TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Not combustible but enhances combustion of other substances.	NO contact with flammable substances.	In case of fire in the surroundings: water spray.
EXPLOSION			In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		AVOID ALL CONTACT! AVOID EXPOSURE OF (PREGNANT) WOMEN!	IN ALL CASES CONSULT A DOCTOR!
Inhalation	Cough. Sore throat.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Redness. Pain.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Redness. Pain.	Safety goggles or eye protection in combination with breathing protection.	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. Refer for medical attention. See Notes.

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 absorb in saw-dust or other combustible absorbents. Do NOT let this chemical enter the environment. Chemical protection suit including self-contained breathing apparatus.

IMPORTANT DATA

Physical State; Appearance
WHITE OR COLOURLESS CRYSTALS

Chemical dangers
The substance decomposes on heating (290°C) producing toxic fumes of nitrogen oxides and lead oxides. The substance is a strong oxidant and reacts violently with combustible and reducing materials. Reacts violently with ammonium thiocyanate, red hot carbon, lead hypophosphate.

Occupational exposure limits
TLV: (as Pb) 0.05 mg/m³ 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 of its aerosol and by ingestion.

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 short-term exposure
The substance is irritating to the eyes, the skin and the respiratory tract.

Effects of long-term or repeated exposure
The substance may have effects on the blood, gastrointestinal tract, kidneys, liver and nervous system, resulting in anaemia, hypertension, kidney impairment, liver impairment, convulsions, paralysis. This substance is possibly carcinogenic to humans. Does cause serious reproductive toxicity in humans.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Melting point (decomposes): 290°C Relative density (water = 1): 4.6 Solubility in water, g/100 ml at 20°C: 52	The substance is toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. In the food chain important to humans, bioaccumulation takes place, specifically in marine and terrestrial organism. 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.
