PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance may polymerize due to warming and under the influence of strong bases and metal compounds. The substance decomposes on burning producing toxic and corrosive fumes , including hydrogen cyanide and nitrogen oxides. Reacts violently with acids, alcohols, amines, bases, amides, phenols, and mercaptanes causing toxic, fire and explosion hazard.

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and through the skin. l toxicity (ref.28); LD50 oral-rat: greater than 1000 mg/kg (ref.30); LD50 oral-rat: 1270 mg/kg b.w (ref. 27); 50 : 1060 mg/kg (ref. 25);

INHALATION RISK:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C on spraying.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the skin and is severely irritating to the eyes. The aerosol is irritating to the respiratory tract. ur when heating (ref. 28); iance (ref.27); 38, scores for erythema: 3.61 (rabbit); rat, 30 min: 0.011 mg/l (ref.27); rats),41,47 (high aerosol conc. may cause pulm. oedema - potent. effect), 44,non cardiogenic pulm. edema (ref.30),43; human-severe asthma soon after indroduction of a new paint contain.
