EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol. Effects of short-term exposure The substance is irritating to the eyes and skin. The substance may cause effects on the nervous system. Exposure at high levels could cause lowering of consciousness. Inhalation of high levels of the aerosol may cause lung oedema. See Notes. The effects may be delayed. Exposure at high levels could cause death.	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 long-term or repeated exposure

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes and skin. The substance may cause effects on the nervous system. Exposure at high levels could cause lowering of consciousness. Inhalation of high levels of the aerosol may cause lung oedema. See Notes. The effects may be delayed. Exposure at high levels could cause death.

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 long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT
The substance is very toxic to aquatic organisms.

NOTES
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.
