  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Risk of explosion on contact with reducing agents or organic materials.    NO contact with incompatible materials: See Chemical Dangers  In case of fire in the surroundings, use appropriate extinguishing media.   

 PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
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 CLASSIFICATION & 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.

EXPOSURE & HEALTH EFFECTS

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

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

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

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. 


Occupational exposure limits
TLV: 0.01 mg/m3, - ppm, as TWA; A1 (confirmed human carcinogen).
MAK: skin absorption (H); sensitization of skin (SH); carcinogen category: 1; germ cell mutagen group: 2 

ENVIRONMENT
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.
