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 Risk of explosion on contact with reducing agents or organic materials.  NO contact with incompatible materials: See Chemical Dangers   
 
EXPOSURE   PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!   
Inhalation Cough. See Effects of long-term or repeated exposure.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety goggles or eye protection in combination with breathing protection if powder.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion See Effects of long-term or repeated exposure.  Do not eat, drink, or smoke during work.  Rinse mouth. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Do NOT absorb in saw-dust or other combustible absorbents. Vacuum spilled material with specialist equipment. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.  Do not transport with food and feedstuffs.

Physical dangers
 

Chemical dangers
Decomposes on heating above 440°C . The substance is a strong oxidant. It reacts violently with reducing agents and organic compounds. 

Occupational exposure limits
TLV: 0.01mg/m³ as TWA; A1 (confirmed human carcinogen); (ACGIH 2011).
MAK: Carcinogen category: 1; Germ cell mutagen group: 2; Sensitization of skin (SH); (DFG 2011). 

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

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

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

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. Repeated or prolonged inhalation may cause nasal ulceration. This may result in perforation of the nasal septum. Repeated or prolonged contact may cause skin sensitization. This substance is carcinogenic to humans. May cause toxicity to human reproduction or development. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 316°C
Density: 3.4 g/cm³
Solubility in water: none 
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur along the food chain. It is strongly advised not to let the chemical enter into the environment. 

NOTES
NEVER use a domestic-type vacuum cleaner to vacuum the substance, only use specialist equipment.
Depending on the degree of exposure, periodic medical examination is suggested.
Do NOT take working clothes home.
