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.	Foam, powder, carbon dioxide, water in large amount.
EXPLOSION

EXPOSURE		PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
INHALATION	Abdominal cramps. Confusion. Cough. Dizziness. Headache.	Local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
SKIN	Dry skin. Redness.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
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. Diarrhoea. Nausea. Vomiting (further see Inhalation).	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Let solidify if molten. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water (extra personal protection: P2 filter respirator for harmful particles).

Separated from strong oxidants. Dry.

PHYSICAL STATE; APPEARANCE:
WHITE, HYGROSCOPIC FLAKES OR CRYSTALS.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance decomposes on heating and on burning producing toxic fumes including nitrogen oxides, ammonia. Reacts violently with strong oxidants producing toxic fumes.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: ppm; 1 mg/m³ (as TWA, as dust) (ACGIH 1993-1993).
TLV (as vapour): 4.3 ppm; 20 mg/m³ (as TWA) (ACGIH 1993-1993).

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour or dust.

INHALATION RISK:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the skin. The vapour irritates the eyes, the skin and the respiratory tract. Inhalation of the vapour may cause effects on the central nervous system.

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, liver.
