TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Gives off irritating or toxic fumes (or gases) in a fire. See Notes.
NO open flames.
Water spray, powder.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE!

 •INHALATION Cough. Shortness of breath. Sore throat. Wheezing.
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
 •SKIN Redness. Pain.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
 •EYES Redness. Pain.
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 take to a doctor.
 •INGESTION Diarrhoea. Weakness.
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Remove all ignition sources. Sweep spilled substance into sealable containers. Carefully collect remainder, then remove to safe place.
Separated from strong oxidants. Well closed.

UN Hazard Class: 4.1
UN Packing Group: III

PHYSICAL STATE; APPEARANCE:
BROWN AMORPHOUS OR BLUISH-RED SOLID.

PHYSICAL DANGERS:
Dust explosion possible if in powder or granular form, mixed with air.

CHEMICAL DANGERS:
Upon heating, toxic fumes are formed. Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: (Inhalable fraction) skin absorption (H); sensitization of respiratory tract and skin (Sah);
Carcinogen category: 2 Germ cell mutagen group: 3A
(DFG 2009).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

INHALATION RISK:


EFFECTS OF SHORT-TERM EXPOSURE:
The aerosol irritates the eyes and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization.
