TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Water spray, foam, powder, carbon dioxide.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Do NOT expose to friction or shock.
In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.
EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE!

 •INHALATION Blue lips or finger nails. Blue skin. Dizziness. Headache. Laboured breathing. Nausea. Vomiting. Disturbed vision.
Local exhaust or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
 •SKIN MAY BE ABSORBED! Redness. Pain. (Further see Inhalation).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
 •EYES Redness. Pain.
Face shield or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION Abdominal pain. Blue skin. Dizziness. Headache. Laboured breathing. Nausea. Vomiting.
Do not eat, drink, or smoke during work.
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Wear protective gloves when inducing vomiting. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
PALE YELLOW CRYSTALS , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
May explosively decompose on shock, friction, or concussion. May explode on heating even in the absence of air. Reacts with strong oxidants and strong bases. On combustion, forms toxic and corrosive gases and fumesincludinghydrogen chloride and nitrogen oxides.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: sensitization of skin (Sh); (DFG 2004).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and through the skin and by ingestion.

INHALATION RISK:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the respiratory tract and is severely irritating to the skin . The substance may cause effects on the blood , resulting in formation of methaemoglobin. Exposure to high concentrations may result in death.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the nervous system , resulting in impaired vision.
