EXPOSURE
PREVENT DISPERSION OF DUST!

INHALATION Headache. Nausea. Vomiting. Weakness. Chills. Fever. Symptoms may be delayed (see Notes).
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
SKIN
Protective gloves.

EYES
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 Abdominal pain. Nausea. Vomiting.
Do not eat, drink, or smoke during work.
Rinse mouth. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
ODOURLESS WHITE POWDER OR CRYSTALS.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
Reacts violently with aluminium and magnesium powders, and with chlorinated rubber on heating causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: ppm; 5 mg/m3 (as TWA) as fume; 10 mg/m3 (STEL) as fume (ACGIH 1994-1995).
TLV (as dust): ppm; 10 mg/m3 (as TWA) (ACGIH 1994-1995).
MAK: ppm; 5 mg/m3; Dust III,5a (1993).


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

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the respiratory tract. Inhalation of dust or fume may cause metal fume fever. The effects may be delayed. See Notes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged inhalation exposure may cause asthma.
PHYSICAL

ENVIRONMENTAL
DATA
N O T E S
The symptoms of metal fume fever do not become manifest until a few hours have passed.
