IMPORTANT DATA

Physical State; Appearance
WHITE POWDER

Chemical dangers
Reacts slowly with water to produce acid.

Occupational exposure limits
TLV not established.

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol.

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly
when dispersed.

Effects of short-term exposure
The substance is irritating to the eyes, the skin and the respiratory tract.

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation exposure may cause asthma.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 371°C Melting point: 255°C Solubility in water, g/100 ml at 20°C: 0.4 Flash point: 362°C c.c.

NOTES

The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance.
