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 amounts .
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. 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:
TLV: 5 mg/m3 as TWA; A5 (not suspected as a human carcinogen); (ACGIH 2004).
MAK: (Inhalable fraction) 5 mg/m3;
Peak limitation category: I(2); Pregnancy risk group: C;
(DFG 2004).
OSHA PEL: none
NIOSH REL: Dust: TWA 1 mg/m3 ST 3 mg/m3 Vapor: TWA 0.22 ppm (1 mg/m3) ST 0.66 ppm (3 mg/m3)
NIOSH IDLH: N.D. See: IDLH INDEX


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 is irritating to the skin . The vapour is irritating to the eyes 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 .
