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 combustible substances or reducing agents.  In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION Risk of fire and explosion on contact with combustible substances.     
 
EXPOSURE   PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!   
Inhalation Sore throat. Cough. Shortness of breath.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective gloves. Protective clothing.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. 
Eyes Redness. Pain.  Wear 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 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
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT absorb in saw-dust or other combustible absorbents.  Do not transport with food and feedstuffs and combustible materials.

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic gases including nitrogen oxides. Reacts with combustible substances. This generates fire hazard. 

Occupational exposure limits
TLV (as Co): 0.02mg/m³ as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued; (ACGIH 2012).
MAK (inhalable fraction): Carcinogen category: 2; Germ cell mutagen group: 3A; Skin absorption (H); Sensitization of respiratory tract and skin (SAH); (DFG 2012). 

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

Inhalation risk
A harmful concentration of airborne particles can 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
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma. Ingestion may cause effects on the bone marrow, heart and thyroid. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 100-105°C
Density: 2.49 g/cm³
Solubility in water: soluble 
Environmental effects from the substance have not been investigated adequately. It is strongly advised not to let the chemical enter into the environment. 

NOTES
Anyone who has shown symptoms of asthma due to this substance should avoid all further contact.
The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.
Depending on the degree of exposure, periodic medical examination is suggested.
Do NOT take working clothes home.
