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, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE See EFFECTS OF LONG-TERM OR REPEATED EXPOSURE.  AVOID EXPOSURE OF (PREGNANT) WOMEN! PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!   
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 .

EMERGENCY RESPONSE SAFE STORAGE
Transport Emergency Card: TEC (R)-61GT5-II.  Separated from food and feedstuffs and incompatible materials. See Chemical Dangers. 

IMPORTANT DATA
Physical State; Appearance
RED-TO-YELLOW CRYSTALS. 

Physical dangers
 

Chemical dangers
Reacts violently with aluminium powder. Decomposes on heating. This produces toxic fumes. 

Occupational exposure limits
TLV (as Pb): 0.05mg/m³ as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued; (ACGIH 2005).
MAK (inhalable fraction): Carcinogen category: 2; Germ cell mutagen group: 3A; (DFG 2006). 

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

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


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
