EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. Effects of short-term exposure The aerosol is irritating to the eyes, skin and respiratory tract. Inhalation of high concentrations may cause lung oedema, bronchitis and bronchospasm. The effects may be delayed.	Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. Effects of long-term or repeated exposure Repeated or prolonged inhalation of high concentrations of dust or fumes may cause effects on the lungs. The substance may cause a greenish-black discolouration of the tongue.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The aerosol is irritating to the eyes, skin and respiratory tract. Inhalation of high concentrations may cause lung oedema, bronchitis and bronchospasm. The effects may be delayed.

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

Effects of long-term or repeated exposure
Repeated or prolonged inhalation of high concentrations of dust or fumes may cause effects on the lungs. The substance may cause a greenish-black discolouration of the tongue.

OCCUPATIONAL EXPOSURE LIMITS
TLV: (as V, inhalable fraction): 0.05 mg/m³, as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans). MAK: carcinogen category: 2; germ cell mutagen group: 2

ENVIRONMENT
The substance is harmful to aquatic organisms.

NOTES
Depending on the degree of exposure, periodic medical examination is suggested. The symptoms of lung oedema 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. Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered.
