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 withcombustible substances andreducing 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
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.

PHYSICAL STATE; APPEARANCE:
BROWN CRYSTALS OR POWDER .

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating at 290°C, 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/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 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:


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): 290°C
Density: 9.38

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.

N O T E S

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.
